I've been fairly strictly primal for just over 2 years, and the only complaint (amidst all the good stuff) is that my teeth seem to have become worse over that period, as in more discolouration and more sensitivity. There may or may not be any connection, but I did come across this article which suggests this way of eating would be great for oral health

Does anyone else have concerns with Primal / healthy teeth? I guess one point I'm concerned about is that meat is quite acidic, so from a simpleton point of view increasing your consumption could cause acid erosion.... any thoughts / experiences out there?
