Hmm as you know I think anecdotal evidence is often worth less than no evidence at all, but this is interesting.

I ate huge amounts of dairy while I had my baby teeth, and had huge amounts of cavities. I think about midway through high school I stopped drinking milk altogether (i lost my baby teeth late)  and never started drinking it again.

Recently I went to the dentist for the first time in over a decade, expecting the worst and all I needed was one very minor filling.

I need more alkaline foods by the sound of things. Most of the enamel on my teeth has disappeared since i've been on this diet.

Did a dentist tell you that, or are you guessing?

I have paid for something like $6000 worth of dental work in my life - my teeth are terrible. Believe me, you'd know it if you had no enamel - it'd hurt quite a bit and be very temperature sensitive.

If you have been inconsistant with your dental care the yellowing is probably from a plaque buildup and staining; stuff like coffee, tea can discolor teeth. As indicated a lack of enamal would be painfully evident.

FTR - saliva glands in the mouth contribute to plaque buildup in certain areas, especially top rear and bottom front. Even if you get a cleaning every 6 months most folk still develop a buildup.

Shouldn`t be an issue on a paleo forum but soda pop is BRUTAL on the teeth. That crap is the Satan of the nutritional world....IMHO.
