Most people think of brushing and flossing as a way to avoid cavities and bad breath. But did you know that your oral health could also be connected to Alzheimer’s disease? A fascinating study published in Science Advances found that 96% of Alzheimer’s patients had Porphyromonas gingivalis—a bacteria commonly linked to gum disease—present in their brain tissue. This finding has sparked new discussions about the impact of oral bacteria on overall health.
We often hear that what happens in the mouth affects the rest of the body, but this research takes that idea to another level. Let’s explore how gum disease might contribute to Alzheimer’s and, most importantly, what you can do to protect both your teeth and your brain.
The Unexpected Connection Between Gum Disease and Alzheimer’s
For years, scientists have speculated that there might be a link between gum disease and Alzheimer’s, but this study provides some of the most compelling evidence yet. So how does a bacteria that thrives in your mouth end up in your brain? Researchers believe:
- Bacteria from infected gums can enter the bloodstream and travel to the brain.
- The inflammation caused by gum disease may contribute to brain cell damage.
- Toxins produced by oral bacteria could play a role in Alzheimer’s progression.
While more studies are needed to fully understand the connection, one thing is certain: keeping your mouth healthy is about more than just your smile—it’s an investment in your long-term well-being.
Simple Steps to Protect Your Oral and Brain Health
Maintaining good oral hygiene isn’t just about fresh breath—it could be a key factor in protecting your cognitive health as well. Here are a few practical steps you can take:
1. Step Up Your Brushing and Flossing Routine
- Brush twice a day with fluoride toothpaste to remove bacteria and plaque.
- Floss daily to prevent harmful bacteria from accumulating between teeth and gums.
2. Use an Effective Mouthwash
Not all mouthwashes are created equal. ProFresh, unlike alcohol-based mouthwashes that provide only temporary freshness, works to reduce the risk of gum disease.
3. Stay on Top of Dental Check-Ups
- Professional cleaning can help remove stubborn plaque that regular brushing can’t tackle.
- Your dentist can catch early signs of gum disease before they become serious problems.
4. Watch What You Eat
- Reduce sugar intake, as sugar feeds harmful bacteria in the mouth.
- Eat foods rich in vitamin C and calcium to keep your gums strong and healthy.
5. Pay Attention to Early Warning Signs
If you experience bleeding gums, persistent bad breath, or gum tenderness, don’t ignore them. These are often the first indicators of gum disease, and early intervention can make all the difference.
The Bottom Line: Oral Health Impacts More Than Just Your Teeth
This study reinforces what dental professionals have been saying for years: your oral health is closely tied to your overall health. While we can’t say for certain that preventing gum disease will stop Alzheimer’s, taking care of your mouth is one simple step toward a healthier future.
If you’re looking for a way to improve your oral hygiene, try ProFresh mouthwash. It’s a clinically tested solution that ensures that you are giving your mouth and gums the best chance to have optimal oral health.

Top Tips for Fresh Breath on a Date
If you want to ensure fresh breath on your next romantic outing, follow these tips:
Brush, Floss and Use ProFresh Mouthwash
Brushing twice a day and flossing removes food particles and bacteria that cause halitosis. Using an alcohol-free mouthwash like ProFresh can give long-lasting freshness.
Stay Hydrated
Be careful beforehand and whilst on the date as even non-alcoholic drinks like fresh orange juice’s high acidity can temporarily alter your mouth’s pH balance, dairy products like milk may leave residues that promote bacterial growth, potentially contributing to bad breath. Drink plenty of water during the day and before your date to keep your mouth moist and wash away bacteria. Avoid excessive coffee or alcohol, as they can dry out your mouth and worsen bad breath. On the night if you are drinking alcohol, try and have a glass of water between drinks.
Choose Breath-Friendly Foods
Before your date, opt for foods that promote fresh breath. Crunchy fruits and vegetables like apples, carrots, and celery help remove plaque buildup naturally. Avoid pungent foods like garlic or strong cheeses before an important night out (on and on the night too!).
Chew Sugar-Free Gum
Chewing gum stimulates saliva production, which helps wash away bacteria. Look for sugar-free options with xylitol, known to reduce bacteria in the mouth.
Carry a Fresh Breath Kit
A small pack of sugar-free mints, a ProFresh Mini Spray Bottle, or even a mini toothbrush can be a lifesaver before a date. Freshening up right before meeting (and during) your date can boost your confidence.
When to Seek Professional Help
If you suffer from chronic bad breath despite good oral hygiene, it may be time to visit a dentist or try using a clinically proven bad breath solution like ProFresh Mouthwash every day to keep on top of the issue. Professional treatments can identify and address any underlying dental or medical conditions causing persistent halitosis.
Final Thoughts: Fresh Breath, Fresh Start
Bad breath shouldn’t stand in the way of your dating success. By maintaining good oral hygiene, staying hydrated, and using a reliable mouthwash like ProFresh, you can ensure your breath stays fresh and your confidence stays high.
If you want a bad breath solution that has millions of satisfied customers (over 7.1 million bottles sold worldwide), then try ProFresh Mouthwash. Our customers keep coming back, because they love the freedom from anxiety and embarrassment.
Try ProFresh Mouthwash ready for your next special get together – its formulated to eliminate halitosis at its source so you can focus having a great date, not worrying about your breath!
Is it Better to use Alcohol-Free Mouthwash? We look at the benefits of using an alcohol-free mouthwash
Maintaining good oral health is essential and includes brushing your teeth, scraping your tongue, flossing and using mouthwash. What is equally important are the products and tools you are using during your oral care routine.
Let’s look at mouthwash. Years ago, many of us weren’t aware that mouthwash contained alcohol, it was probably only when alcohol-free mouthwashes became available that we realised that our regular mouthwash had alcohol as one of its ingredients.
These are the benefits of using an alcohol-free mouthwash
Prevents Dry Mouth
Alcohol is a drying agent and it has the same affect on the inside of your mouth. Saliva plays an important role in good oral health as it neutralises acid produced by bacteria and washes away food particles. Bacteria can thrive in an oral environment that is dry and this can lead to bad breath and an increased risk of oral cavities.
Switching to an alcohol-free formula, like ProFresh, helps to maintain a healthy level of moisture in the mouth, allowing saliva to do its job effectively.
More Gentle on Gums and Soft Tissues
Mouthwashes that contain alcohol can cause a burning sensation in the mouth. This can irritate sensitive gums and soft tissues and could make people more susceptible to gum disease. Some people suffer from xerostomia (dry mouth) and this is made worse by exposure to alcohol.
Ideal for those with Dental Composites
Alcohol-free mouthwash is generally recommended for people with dental composites because it’s better for the colour, hardness, and wear of tooth composite restorations.
Better for Long Term Use
Ideally you should be using mouthwash a minimum of 2 times a day, some people brush their teeth and rinse after every meal or snack. Long term use of alcohol based mouthwash can cause tooth sensitivity and can erode the enamel on teeth and irritate the soft tissues of the mouth. Using alcohol-free mouthwash allows you to rinse as many times as you need without the worry of discomfort.
Alcohol-Free Mouthwash Effective at Fighting Bacteria Without the Harsh Effects
Alcohol-free mouthwash is no less effective than mouthwash that contains alcohol, you just don’t have the negative side effects that alcohol containing mouthwash can bring.
With the right alcohol-free mouthwash, like ProFresh, you can enjoy fresh breath, healthy gums, and a cleaner mouth – all without the harsh effects of alcohol.
How to Overcome Social Anxiety due to Bad Breath
And how ProFresh Mouthwash can help…
People can feel social anxiety for many reasons; lack of confidence, poor self-esteem, trauma etc but did you know that it’s possible to suffer social anxiety due to having or fearing you have bad breath.
Worrying about bad breath can lead to anxiety that can affect both personal and professional relationships. We’d like to explore how you can overcome anxiety and get your confidence back.
What is Social Anxiety?
Social anxiety is an overwhelming fear of social situations. You can feel fear about starting face to face conversations at work or socially, going to parties, work meetings and even going shopping. The physical symptoms are your heart may race and you could suffer palpitations, your mouth gets dry (which makes bad breath worse!), you could blush or sweat. Mentally you are convinced people are judging you or whispering about you. When you think you have bad breath social anxiety is even more difficult to deal with as you probably feel you can’t tell anybody your fears.
Ways to Cope with Social Anxiety
- Mindfulness and relaxation – including deep breathing and meditation.
- Professional support – Consider help from a therapist who can provide you with tools to cope with social situations.
- Positive Self-Talk – When you hear negative thoughts in your head challenge them and defend yourself from those negative thoughts with positive ones.
- Gradual Exposure – Slowly build up to social events by starting with one or two people and working your way up.
- Live healthily – get sleep, eat healthily, exercise (which is a great stress reliever) and avoid alcohol (which dries out the mouth AND can cause anxiety).
Last but not least – if your social anxiety is related to bad breath then ProFresh can help.
ProFresh Mouthwash is formulated to get rid of bad breath, not just mask it. Unlike other mouthwashes that provide temporary relief, ProFresh ensures your breath stays fresh for hours.
Using ProFresh twice a day ensures your breath stays fresh giving you the confidence to walk into a room and not have to worry about covering your mouth with your hand or standing back from people. We even have a ProFresh Mini Refresher Bottle that’s small enough to keep in your small bag or pocket should you need that extra confidence boost.
How many of us have been in a situation where you are having a close-up conversation with a loved one or friend and you get hit with a bad smell? Could be eggy, plastic like, gassy, or even chemical like (read here on what different breath smells mean) but whatever it smells like, you know it’s bad breath.
Bad breath is a very embarrassing issue to deal with but it’s also very common. You obviously want to help this person but it’s a very difficult subject to address and has to be done with the utmost sensitivity and empathy. Let us help give you some advice should you be in this situation.
- Get the Timing Right. We won’t need to tell you this but don’t have a sensitive conversation like this in public or in front of other people. The person you are telling is going to feel embarrassed enough without others hearing. I have witnessed someone telling their partner their breath smells in front of a room full of people and I felt awful for them. Find a quiet moment when you know you won’t be disturbed.
- Be Compassionate. This subject needs to be approached with kindness. You could say something like “I noticed your breath smells a little recently, have you been feeling unwell”. Explain that you don’t want them to feel embarrassed, you just want to help them. If you can, try and avoid using the term “bad breath”.
- Offer Suggestions to Help Them. How about saying something like “I suffered with my breath a while back and I found that …….. really helped me”. Or “I know a friend who uses …….”. Try and help them by making them feel that others suffer with bad breath too and they aren’t the only ones.
- Reassure. At the end of the conversation make sure you say you are always there to talk to and you are happy to help them try and find a solution to their breath issue.
If you really can’t face telling them, you could drop subtle hints like offering them a mint or gum or you could order them a bottle of ProFresh anonymously. It’s always kinder to tell someone but it’s a difficult conversation to have with someone you care about. Just remember.
- Don’t make fun of them
- Don’t tell them in front of others
- Don’t call it bad breath (“your breath isn’t so fresh recently”).
- Be there for them if they need to talk about it.
The Link between Oral Health and Wellbeing
Did you know that there is a direct link between good oral hygiene and your overall wellbeing?
Well there is and we think it’s really important for you to understand this connection.
We already know that good oral hygiene is essential for a healthy mouth however most people don’t realise the impact oral health has on your overall health and wellbeing. Research papers have been written that demonstrate this link.
Oral Health and Heart Health
A few studies have shown a link between gum disease and an increased risk of cardiovascular diseases such as heart attack and stroke. A study published by the American Heart Association found that those with periodontitis had a higher risk of developing heart disease than those with healthy gums. It is believed that inflammation and bacteria from the gums might play a role in the development of cardiovascular disease. Another recent study examined this link more closely and tried to find out the actual cause of this correlation : Cardiovascular and Oral Health Study
Oral Health and Diabetes
Research has shown that those with diabetes are at a higher risk of developing gum disease and those with gum disease are more likely to develop diabetes. If your diabetes is not controlled well, this can lead to increased levels of glucose in the saliva. This provides an ideal environment for bacteria to thrive which leads to gum inflammation. On the flip side, gum disease makes it more difficult to control blood sugar levels which could worsen diabetes symptoms. Looking after your oral health as a diabetic is so important if you wish to avoid complications. Diabetes and Oral Health Study
Oral Health and Respiratory Health
A link has been found between poor oral health and infections of the respiratory system. Bacteria from the mouth can be aspirated into the lungs leading to infections such as pneumonia. The elderly and those with weakened immune systems are particularly vulnerable. Read this really interesting research paper from the UK. Respiratory and Oral Health Research Study
Oral Health and Mental Wellbeing
Some studies have pointed towards a connection between poor oral health and mental health issues such as depression and anxiety. Persistent oral infections and gum disease could contribute to systemic inflammation which has been link to mood issues. Equally if someone is suffering from mental health issues, they may start to neglect their oral health which simply exacerbates their mental health issues. Another useful study for you to look at: Mental Health and Oral Health.
These are just a handful of studies that have been done, but these show you the extensive research that has been done into the correlation between oral health and wellbeing.
Now we understand more about the link between oral health and our general wellbeing, we owe it to ourselves to have the best oral care routine we can. This involves:
- Floss
- Rinse with mouthwash
- Tongue scrape
- Rinse with mouthwash again
- Brush
If you already use ProFresh Mouthwash you know you are already taking an important step towards maintaining good oral health which of course has a positive effect on your general wellbeing.

Can Bad Breath be Tasted or Smelt whilst Kissing?
Many people who suffer from bad breath may wonder whether the person they are kissing can smell their breath. We hope to help find the answer to that.
Kissing isn’t just a physical act, multiple senses are involved such as taste and smell.
So can the person you are kissing smell your breath?
Understanding Taste and Smell
Taste and smell are very closely interlinked. When we eat, drink or breathe in through our nose, tiny receptors pick up on molecules. These receptors send signals to our brains to create the sensation that we interpret as taste and smell.
Whilst kissing, your noses are close together and your breath will no doubt be part of the same air space as the nostrils of the person you are kissing. Unfortunately its highly likely they will be able to smell it.
Can someone Taste my Bad Breath whilst Kissing?
Our taste buds can detect certain flavours and bad breath can sometimes be tasted during a kiss particularly if someone has strong or offensive breath. The food and drink you have consumed will also have an impact on whether your breath smells and can therefore be tasted. For example eating garlic or onions can make one’s breath smell very strong. Smoking makes your mouth taste like an ashtray and drinking alcohol dries your mouth out which can also cause bad breath.
What can you do to stop your partner smelling bad breath whilst kissing?
- Stay hydrated – drink water to prevent dry mouth and wash away bacteria.
- Have good oral hygiene – brush teeth and rinse with mouthwash twice a day and floss once a day too. Tongue scraping is also vital to your oral care routine – on the back of most people’s tongues is a layer of mucus where food debris and bacteria will get stuck. Read here to find out more about how important tongue scraping is.
- Use an effective mouthwash – rinsing with a good mouthwash (like ProFresh Mouthwash) will not only help get rid of the bad bacteria but can reach those hard to reach places.
- Diet – if you know you are going to be getting up close and personal then watch what you eat! Avoid spicy or strong smelling foods beforehand. If you are drinking alcohol, then try and drink water in between drinks to keep your mouth hydrated. You could always keep a mini spray bottle of mouthwash with you ready for those romantic moments!
- Regular Dental or Hygienist appointments – this is SO important. Make sure you visit your Dentist regularly for check-ups so you can maintain good oral hygiene.
To summarise, yes bad breath can have an unwelcome presence whilst kissing. It’s more likely the smell of the bad breath will be an issue than the taste (unless you’ve been eating spicy foods or smoking). Taking good care of your oral health at all times will stop the anxiety of these intimate moments with your partner.
They say communication is important but bad breath is a subject that none of us really want to talk about quite frankly. If you are the person who suffers with bad breath then follow our tips above to ensure you have fresh breath but if it’s your partner with bad breath, that could be more tricky. That might well make for another blog post! Read How to Tell Someone they have Bad Breath
Can you smell your own breath if it’s bad?
Bad breath also know as halitosis is or has been a concern for most of us at some point of our lives. Whatever causes the bad breath, it’s impact on one’s confidence can be fairly stressful.
The short answer to the question of whether you can smell your own breath is – no. It’s fairly difficult for a person to smell their own bad breath. Unfortunately it may take someone else to comment or you may just notice a different taste in your mouth.
When it comes to detecting different smells, the nose is an amazing tool for the body but unfortunately not when it comes to smelling our own odours. Our brains are designed to filter the smells we are used to which is known as the “olfactory adaption”. Think about the scent of your own house – you don’t think your house has a scent but other peoples houses do. Your house does have its own signature scent – you smell it all the time, so your nose filters it out.
Why can’t I smell my own bad breath?
When you breathe out, air comes out from your mouth and any odour from your breath will mix with the surrounding air and away from your nostrils thus making it difficult to smell your own breath. Therefore it’s much harder to smell your own breath the way we easily smell someone else’s.
So how do I know if I have bad breath?
Well in our opinion, in order of reliability:
- Most Reliable : Ask someone.
Yes we know it sounds like the worst suggestion in the world BUT it is the only truly reliable way to know for sure. Ask your partner, best friend, family member or even your child (let’s face it, kids can be brutally honest). Don’t ask after a sip of coffee or after spicy food. Brush your teeth, wait a couple of hours and then ask. You could always ask your Dentist or Dental Hygienist. That way you will get an honest professional and more importantly, confidential opinion.
- Fairly Reliable: The Lick Test
Ever heard of the Lick and Sniff test? Simply lick your wrist from as far back on the tongue as you can, allow to dry for a few seconds and then sniff. This will give you an idea of what your breath may smell like to others because the compounds in our saliva mimic those found in your breath.
- Fairly Reliable: Floss and Sniff
Use floss or interdental brushes between the backs of your teeth and then smell the brush or floss. If there is a bad smell coming from the tool, then it could mean you have bad breath causing bacteria in your mouth. We do have a solution to this! Firstly, ensure flossing is a daily part of your oral routine. Between each tooth, dip the floss into a cap of ProFresh Mouthwash, this not only clears the gunk of your floss or brush, but when you place the tool back between your teeth, the ProFresh Mouthwash will get to work in places that your mouthwash and toothbrush may not reach with simply rinsing or brushing.
- Not very reliable: The Mirror Test
Most of us at some point have tried the “breathe into your hands and smell trick”. Your breath will disappear very quickly into the surrounding environment and the only way you will notice any odour is if your breath leaves some residue on your hands which we can smell when we sniff our hand. Which is fairly unlikely.
- Jurys out: Breath Checker
This is a handheld electronic gadget designed to sense VSC’s (Volatile Sulphur Compounds) and produces a parts per billion (PPB) measure of foul smelling compounds. My personal opinion is, that unless your breath is being measured in a professional Dental Clinic using a more sophisticated piece of equipment such as a Halimeter, I would take the readings of a hand held gadget with a pinch of salt.
So the final verdict?
Can you really smell your own breath – not really. Aside from number 1 – Ask someone – the other methods are not fool proof. So if you think you have bad breath, if you are too embarrassed to ask your friend, family member or partner, book an appointment with a Dentist or Hygienist. They are there to help.
If you want to understand more about bad breath, you may be interested in our blog post on What Does Bad Breath Smell Like which describes the different bad breath odours and their possible causes.

In this blog we ask
- Why do I still have bad breath even though my oral hygiene is good?
- Does my breath really smell bad?
- What is bad breath?
- What are the causes of persistent bad breath?
Why do I still have bad breath even though my oral hygiene is good?
Bad breath is a condition that affects millions of people worldwide, yet it’s a subject that most people are too embarrassed to discuss or ask advice about. We all know that the best oral care routine involves brushing, flossing, tongue scraping and rinsing but what if you are already doing that and you still have bad breath – or think you still have bad breath.
Does my breath really smell bad?
Our first piece of advice would be – ask someone to smell your breath. I know this sounds like it’s the most excruciating thing you could do but you may not have bad breath – you may just have a bad taste in your mouth or if someone else has it you assume you have it too. You could ask your parent, best friend or partner. Lets face it, kids are quite honest about things like this so they are worth a try. Don’t ask if you’ve just brushed your teeth, used mouthwash or eaten/had a strong tasting drink, just ask spontaneously. If you are told your breath does smell a bit whiffy, read on.
What is bad breath?
Bad breath also known as halitosis is a condition where your breath has a bad or odd smell to it. If someone is sitting very close to you, you should be able to just feel the warmth of their breath not smell anything. Bad breath can be an embarrassing condition and can cause anxiety in social, intimate and work situations. Some people even avoid getting into a lift if they think their breath smells bad. Poor oral hygiene more often than not is the cause of halitosis but if you think your oral care routine is very good then there are causes of bad breath.
What are the causes of persistent bad breath?
- Food stuck between teeth or inside mouth. You’ve been told by your dentist or hygienist many times that you need to floss every day. We may think we have removed every food particle from the mouth or between the teeth, but the chances are there are still some food particles lingering around somewhere. As these particles break down they release sulphur compounds which release a smell into your mouth and out through your breath. The gaps between each tooth will differ and therefore you need the right equipment. You could try Wisdom Clean Between Flossers or Wisdoms Interdental Brushes which are available in different sizes to enable you to floss between each tooth effectively. Drinking water after a meal is a good idea, give the water a good slosh around in your mouth before swallowing, this will help get rid of a lot of the main food particles.
- Gum Disease – You may have a super oral care routine but sometimes with the best will in the world, you can still end up with gum disease. If your gums are red or inflamed, this is often a sign of gum disease and your gums will become a breeding ground for bacteria that cause bad breath. If you think you may have gum disease, please visit your Dentist or Dental Hygienist where you can get professional advice. In the meantime, use an alcohol-free mouthwash such as ProFresh to keep your mouth in good condition.
- Dry Mouth – A reason why we suggested an alcohol-free mouthwash in the paragraph above is that alcohol is not only an irritant but it can also dry your mouth out causing bad breath or making existing bad breath worse. A dry mouth does have an official name – xerostomia – and this can create a breeding ground for bacteria. Saliva is our body’s natural cleaning process for the mouth and rinses away bacteria and food particles and if there is not enough saliva – then bad breath rears its ugly head. Dry mouth can be a side effect of medication so it is worth mentioning to your GP if that’s the case.
- Sinus Infections and Issues – Sinus infections can cause post-nasal drip (dripping down the back of your throat – into your throat or onto the back of your tongue) and other respiratory issues. Bad breath isn’t always caused by an issue in the mouth and infection in your sinuses can cause foul smelling breath from the mouth. Post nasal drip (mucus) can sit on the back of the tongue and food particles can get stuck to it and that will attract bacteria. With persistent sinus infections it is worth visiting your GP surgery. In the meantime use a Tongue Scraper to ensure you tongue is clear.
- Other Health Factors and Diseases – Bad breath can sometimes be a symptom of other underlying health issues. Diabetes, gastrointestinal disorders, liver or kidney problems can produce a particular odour that can be smelt on the breath. For a breakdown of the different types of smells of bad breath and their possible meaning, read our last article on What Does Bad Breath Smell Like?
To ensure your oral care routine is the best in can be read our How to Use article which gives you step by step instructions on how to get the best out of your oral care routine and products.
What does bad breath smell like?
Halitosis – more commonly known as bad breath smells differently depending on the cause. It’s difficult to know whether your own breath smells or not, we can sometimes tell by the taste in our mouths. Hopefully you have a really honest friend or family member that you can ask. You might find your breath doesn’t smell at all!
We have researched the various odours that can occur and described them below and suggested some solutions:
Faeces or Poo-like
There could be issues with the digestive system. Are you constipated or do you have any bowel issues? IBS or other digestive problems? It may be worth speaking to your Nurse or GP.
Rotten eggs or sulphur
This is bad breath caused by the breakdown of proteins by bacteria in the mouth. It is quite common. The sulphur compounds in your mouth such as hydrogen sulphide and methyl mercaptan leads to this eggy smell. Unfortunately there are many foods that can cause this rotten smell and they include, garlic, onions, egg, cruciferous veg (broccoli, cabbage etc), high protein meat and fish, coffee and alcohol.
We clearly can’t stop eating these foods as they are good for us (well aside from the alcohol) so if we are aware they can cause an eggy smell from your mouth, you can use ProFresh Mouthwash after eating them and then brush your teeth if it is convenient to do so.
Mouldy or musty
These type of smells could mean you have sinus issues/infection or that you have respiratory issues. If you think this could be the case, then again, please consult your GP. I have personally smelt this on a couple of people who have respiratory issues and it’s not pleasant.
Acidic or sour
This may indicate issues such as acid reflux or GERD (gastroesophageal reflux disease) where stomach acids flow back up into the mouth and esophagus. You can prevent acid reflux by maintaining a healthy weight, avoid certain foods like spicy or fatty foods, citrus fruits, tomatoes, chocolate, caffeine and alcohol. Make sure your portion sizes are smaller and you don’t eat anything for a few hours before bed.
Sweet or fruity
Has been described as a smell similar to pear drops, the sweets we may have eaten as children. There are a few reasons for this smell – a high protein, low carb diet, fasting and some mouthwashes which containing sweeteners or fruity flavours. This smell can also be a sign of diabetic ketoacidosis where the body products high levels of bloods acids called ketones so please bear that in mind. My midwife smelt this on me during my pregnancy. All was ok, but they kept a close eye on me.
Chemical smell
Some drugs or medications can make the breath smell similar to chemicals. Some prescription drugs cause a dry mouth which can cause bad breath – saliva has bad breath fighting properties so it’s important to practice good hygiene but of course speak to your local pharmacist or GP if you are concerned.
Antibiotics for example, though are great at fighting infection can disrupt the natural balance of bacteria in the mouth leading to an overgrowth which causes bad breath. Again, ensure your oral hygiene is excellent at all times, particularly when taking medicines.
Bad breath can be an annoying side effect of your diet but could also indicate a health issue. Please do speak to your Dentist, Oral Hygienist or GP if you have concerns.
