Dentist told me yesterday actually, I'm a classic example...either people have tooth decay and no bone loss, or bone loss but no tooth decay....
I've had my share of cavities no doubt but I have boneloss beneath the gums and did that "scaling" to help grow back and tighten the gums at least....so I think your stuck with getting cavities
Although I did read the raw milk drinkers swear that they stop brushing their teeth and have zero dental issues....maybe it'll help?
