The Science Behind a Smelly Dental Guard

If you've used a dental guard before, you're well aware of the perils of long-term use... not to your teeth, obviously, your teeth are protected! Rather, the result of months of use: The smelly guard.  But what causes that awful smell?

Let's talk a little bit about what's going on inside your mouth and the ways that you can protect your guard, just as you would your teeth and your overall oral health.

Oral ecology: It sounds fancy, but it's basically just a way to describe the system of organisms that live in your mouth. And we all have them – don't think that just because you brush your teeth four times a day that your mouth is bacteria-free! In fact, a microbe-free mouth something that you absolutely do not want.

The two main components of oral ecology are bacteria and saliva, both of which have the capability to harm you but also, in many instances are both beneficial and necessary in order to protect your immune system. Saliva, for example, contains many of its own bacterial enzymes such as lysozomes which are there to kill any harmful bacteria you might encounter and ensure that the ecology of your mouth stays balanced.

The surfaces of your teeth, of course, are extremely complex and therefore saliva can't possibly wash away all of the bad bacteria... and this is what leads to plaque.

The main suspects in poor oral hygiene are:

• Streptococcus mutans: These are the bacteria that feed on sugar and starches, producing acids that erode your tooth enamel. They are the main cause of cavities and other oral diseases.
• Porphyromonas gingivalis: Over time, poor oral hygiene can also lead to periodontitis a.k.a. gum disease. These bacteria begin to take up residence when gums are damaged and over time, will also wreck havoc on the alveolar bone that supports your teeth.

In short, the generation of these tissue and enamel-damaging substances is what creates that unpleasant smell; bad habits such as smoking, chewing tobacco or vaping can exacerbate things, too. Provided you cut out bad habits, you'll still need to ensure that you brush and floss regularly in order to keep the bad bacteria in check. (Using an antimicrobial mouthwash also helps!)

You should rinse or soak your dental guard in warm water immediately after you wear it, brush it with a soft toothbrush – not the brush you use for yout teeth, one that is just for your guard – using a small amount of anti-microbial soap, then rinse very thoroughly. 

Of course, over time both the wear and tear on your guard from grinding – which is what keeps your teeth safe! – as well as cumulative bacterial growth means that replacing your guard every few months is your best bet. We described this a bit in a previous blog, but basically ClearClub's subscription option offers a convenient, low-cost way to receive a new guard every three to six months using the same impressions you only need to take once.
