Tooth Decay & Gum Disease

The mouth is a constant battleground where billions of invading bad bacteria attempt to displace the natural good bacteria that protect our teeth and gums. BLIS M18™ is a special strain of good bacteria designed to prevent bad bacteria occupying the oral cavity and keep teeth and gums healthy.

Isn’t it enough to brush and floss my teeth every day?

Billions of bacteria live in the mouth and we encounter many millions more on a daily basis.  The bad ones invade our teeth and gums with every intent to displace the good bacteria.   When the bad bacteria succeed, we see dental problems such as tooth decay and gum disease.

Every time you have a meal, the bacteria that naturally reside in your mouth feast on the food you eat. Just like every other living organism, these bacteria excrete waste after a meal. This waste is highly acidic and breaks down tooth enamel, causing root decay and cavities.

It’s important to brush and floss to get rid of as much of that waste as possible but there are places that brushing and floss cannot reach.  And the little particles of food left in your mouth continue to break down and cause damage.


Over time plaque forms and then hardens and calcifies on your teeth.  Once plaque has calcified, it’s impossible to remove with a toothbrush and floss and can only be removed by the hygienist during teeth cleaning.

Gingivitis (gum inflammation) usually precedes periodontitis. However, it is important to know that not all gingivitis progresses to periodontitis. In the early stage of gingivitis, bacteria in plaque build-up, causes the gums to become inflamed and to easily bleed during tooth brushing.

Without care and attention, dental issues like tooth decay, cavities, plaque, and gingivitis could lead to periodontal disease and potentially cause more serious medical complications such as heart disease.

ToothGuard and ToothGuard Jr. are advanced oral probiotics that contain BLIS M18™ - a patented strain of Streptococcus salivarius that has been clinically proven to support and promote healthy teeth and gums.
