Take Care of Your Teeth to Support Your Immune System

The gut starts at the mouth so it should be no surprise that the bacteria and microbes that live in our oral cavity affect overall health and wellness. But chances are good that if you’re feeling under the weather, the last thing that’s on your mind is what’s happening in the world of your oral microbiome. You just want to feel better, fast!  

The reality is that our mouth is the gateway to the body and scientists are discovering what a vital role it plays in how we feel each day. And, believe it or not, your entire oral cavity is teeming with bacteria—this includes your teeth, gums, tongue, tonsils, and sinuses.

Furthermore, if there aren’t enough of the good guys dwelling within your oral microbiome to maintain a healthy microbial balance, it can become challenging to keep feeling your best.

Supporting Your Oral Microbial Superheroes


It's so important to maintain a plentiful population of the right oral probiotic strains. These strains were designed by nature to assist in the immune system’s first line of defense—guarding the gate, if you will—so your whole body benefits.

Specifically, S. salivarius K12 and M18 are two highly beneficial probiotic strains traditionally present in the mouths of healthy individuals. In fact, S. salivarius bacteria colonize in the upper respiratory system just a few hours after birth and become some of our body's first defenders, helping to keep us well as the immune system matures during early childhood.1

These two key strains also produce powerful antimicrobial molecules called BLIS (bacteriocin-like-inhibitory substances) that work to keep bad guys at bay by competing for space and nutrients in the oral cavity.2 

An abundance of good bugs paired with this specialized BLIS activity supports overall microbial balance, a robust immune system, strong teeth and gums, and a healthy upper respiratory system.

Unfortunately, there are many reasons that most of us don’t have an abundance of these two key strains of bacteria present in our mouths. They range from using oral hygiene products like common mouthwashes and toothpastes designed to wipe out bacteria to consuming sugary beverages, smoking, or simply not caring for our oral health as we should.

Supplementing for Oral and Immune Health

While you can get probiotics into your system through fermented foods, it’s very difficult to obtain enough of these two important probiotic strains: S. salivarius K12 and S. salivarius M18, and thus an excellent option is to supplement with a probiotic designed specifically for maintaining oral health.

Beyond dental and immune system benefits, taking an oral health probiotic can also benefit your breath (which may in turn benefit your life). In the Archives of Oral Biology, L. Masdea and other Swiss scientists reported that S. salivarius K12 produces antimicrobials that help curb the bacteria that creates bad breath.3

If you’re looking to support your oral and immune health—and freshen up your breath while you’re at it—then a natural, chewable probiotic supplement like Hyperbiotics PRO-Dental is the perfect choice.

With S. salivarius strains BLIS K12 and BLIS M18, you’ll help maintain a thriving community of your body’s natural, powerful superheroes to keep your upper respiratory and immune systems functioning at their best. PRO-Dental also includes Lactobacillus strains L. paracasei and L. reuteri that further act on your behalf to help discourage intruders, while supporting oral wellness.

We have roughly 90% more bacterial cells than we have human cells which means that it’s imperative to keep microbial health at the forefront of your mind if you’re looking to feel your finest.

In addition, there are a myriad of startling and fascinating studies on the direct correlation between oral wellness and heart health, blood sugar levels, pregnancy wellness, bone and joint health, and immune function—each implicating poor oral health as a factor in the degradation of health in other areas. We look forward to learning more as the quest for understanding continues.

So whether you’re seeking to support overall wellness or maintain your health throughout the seasons, remember that a vital part of your immune health actually begins within your mouth.
