Well either way, it exists, and the FDA is apparently going to say it's not harmful. I'm in the "nobody in my entire extended family has ever had a single cavity" club, so no dog in the race for me other than my strong suspicion that the line of reasoning behind managing the risk of cavities by managing the microbiome in the mouth is the right approach.

Is there a good way to order genetic sequencing of s.mutans from my own mouth? Have we gotten to the point where a lab test like this is inexpensive enough to be done for the sake of curiosity?
