I bet it is, they just haven't noticed it yet.
Periodontitis is linked to heart disease and inflammation. Inflamation and circulatory problems can probably be linked to all kinds of stuff.
The company Viome has a oral kit out along with the rest of their testing protocol. And they’re supposed to tell you what’s going on in your mouth in the way of cancers and other problems. I ordered the kit and I plan to take it in 2 1/2 months. My problem is that I started a penicillin protocol and you have to wait 2 1/2 months before he can take a test. But I’m interested to see how my mouth rates because I have had periodontal problems for the last 40 years.
