This is "ONLY" a problem for those who do not take enough Alkalizing Minerals to enable the body to rebuild it's self!
Those people who just take a token amount and are still very short of the needed Alkaline Minerals , may be those who have these problems!
For, "IF" you have enough of the needed Alkaline Minerals, then your teeth may grow Fast and Strong and the lemon juice or ACV may not cause "ANY" problems!
And generally those people who run into these problems may be "VERY" short of the needed Calciums!
So "IF" you provide your body with enough Calcium and other needed Alkalizing Minerals, then you may "NOT" have this problem!!!!!!!!!!!!!!!!!!!!!!!
