I just went down a rabbit hole researching a toothpaste that's giving me constant ads. I went looking for reviews and ended up posting a comment on /r/PeriodontalDisease - https://old.reddit.com/r/PeriodontalDisease/comments/1bcna04...

TL;DR: EDTA is the magic ingredient that will annihilate the disease-causing biofilm on your teeth & gums, especially when you fund your own studies and spend the rest of your money made from your overpriced toothpaste gel on marketing.

Just brush and floss 2x a day, and chew gum if you like to.
