Anyone have any recommendations for a "natural" toothpaste? I do have sensitive teeth and Sensodyne is the only toothpaste I have found that really helps. I've recently found out however, that the parent company tests on animals :-( The natural toothpastes, I have seen do not have fluoride and am wondering if this is an issue. When I lived in NB, there was no fluoride in the water and we were told that fluoride supplements were recommended. Does anyone have any advice for my toothsome dilemma?
