ago, or when ever pro health crest came out, I was one of the first to try it. Until I read all comments, I never associated the skin inside
. Thinking back, it was a little while after brushing & i had changed to P.H. Crest. I didn't care much for it & switched to something else & i haven't had it since. someone mentioned menopause, well i was in the worst part of it, if there is one part worse than the others. Now, I have no teeth in my mouth.
