Can Snoring Cause Bad Breath?


Can snoring cause bad breath? The simple answer is yes it can contribute to it and be a cause. In this article, we will show you how and the best ways to help bad breath caused by snoring.



Snoring: The Cause Of Bad Breath Or A Convenient Scapegoat


Snoring and mouth breathing and snoring are significant causes of bad breath. Mouth breathing dries your mouth’s mucous membrane – that’s the smooth, wet lining of your mouth. Saliva is a natural antibacterial agent, so when this dries up as a result of mouth breathing, it becomes easier for those bugs to grow. These bugs can cause nasty smells. If you particularly notice your bad breath in the morning it is possible you have been mouth breathing and even snoring through the night.

The ‘bugs’ discussed are bacteria. These bacteria change and multiply, before beginning to release sulphur-based compounds, often in the form of gases. These are sometimes referred to as Volatile Sulphur Compounds (VSCs) and give the smell that results in bad breath. Saliva, therefore, plays a critical role in the prevention of bad breath1. Snoring dries out saliva. This is the link between snoring and bad breath. This is exactly how snoring can be a cause of halitosis.

How To Stop Bad Breath


We often hear about trying to improve our mouth odours through good oral hygiene. This would include brushing our teeth, flossing and using mouthwashes to remove these harmful bacteria. Good follow-up dental care is also critical. This all ensures there are no places in the mouth for these potentially ‘smelly bacteria’ to hide.

It’s also vital that we ensure that there are no other medical conditions that may also be causative, such as sinusitis. In this search for a cause of bad breath, it is interesting to consider how critical saliva is2 and to understand how dramatically mouth breathing and snoring may affect it. If you have good oral hygiene or improving it hasn’t helped your own bad breath you may need to seek a healthcare professionals advice. However, if you think that snoring might be a cause of your problem – read on.



What Does Research Say about snoring and bad breath?


There has been much research that links bad breath (halitosis) with alcohol intake and obesity. Interestingly, both of these are also factors that increase snoring3.

It could be that people who drink more alcohol and are obese are more likely to snore, therefore drying their mouth membranes. That then increases sulphur-producing bacteria around their mouth and gums. However, it is also possible that the mechanism is completely separate, and that alcohol and obesity are independently able to cause bad breath.

This 2007 research paper by Rosenberg does seem to confirm the link between alcohol intake, obesity and halitosis. It arguably appears the simplest explanation and certainly one to closely consider when looking for an answer.

In this search though, it is interesting to consider that our snoring could be contributing to the bacteria in our mouths that cause bad breath. Therefore, if we can address our snoring we may have a solution. We do not need to try and prevent the smell of the VSCs or to try and ‘cover up’ the issues. By addressing the snoring, we may be able to tackle the issue at its root.



How To Stop Snoring To Prevent Bad Breath


The problem is that snoring itself is not the easiest condition to cure. In fact, you may be interested to read this article, for more detailed information on stopping snoring: “What Can I do to Stop Snoring?”.

When considering the research around this link we must also consider that the issues arise, not just from snoring but also from mouth breathing. For this reason, mouth devices that are worn overnight may not be the right solution. Even when they are effective in preventing snoring, it is unlikely to be as effective in reducing halitosis and dry mouth. In fact, if the device encourages an open mouth it would make it worse. If it increases mouth breathing, it would be detrimental.

Few devices offer solutions to snoring without having to wear a device at night.




Snorgo is one such device. This simple product offers a potential ongoing solution to not snoring at night without needing to wear a device overnight. Snorgo is used during the day at the user’s convenience. Evidence suggests using the device for just one minute, three times per day, can bring great results. Some users beginning to see a benefit in their first week. Ideally, this exercise is continued for 6 weeks to help strengthen the palate and stop it from becoming floppy. Initial work reported 100% satisfaction with the product and further independent research was done by The Innovation Agency NW. Their role is to find potential medical products for the future and Snorgo is one such device. Their research found 75% of users and partners reported significant improvement in snoring a few weeks.


Whilst highlighting bacteria, it may also be of interest to learn that Snorgo is a device that has taken the trouble to incorporate Biomaster technology. Biomaster has been a pioneer in antimicrobial additives. Check out how Biomaster works with Snorgo or the Biomaster website for more details.







In Summary


So, can snoring cause bad breath – In short – yes it can. There is little doubt snoring can contribute to bad breath by drying out the membranes of our mouths, causing bacteria to build up. Saliva is one of the mouth’s primary defence systems, but mouth breathing and snoring can contribute to the removal of saliva.

Whilst other causes of bad breath are well recognised when considering your own problem, if you have ruled out other conditions, you may wish to consider snoring as a potential issue. If you want to explore options for addressing your snoring, we have directed you to further papers that might help.

It’s important to be aware though that many snoring devices, in particular those worn at night, may not help the mouth-drying issue and therefore, even if they do help with your snoring, may not stop the bad breath.

Snorgo however is different. Rather than simply reducing the snoring, it works to tackle the root cause through exercise. This can potentially offer you a solution to both your snoring and your bad breath.
