This review is from: Kiss Your Dentist Goodbye: A Do-It-Yourself
  Mouth Care System for Healthy, Clean Gums and Teeth (Paperback)
  I picked up this book from the library yesterday. Read it cover
  to cover and just finished it. Photocopied several pages and
  took copious notes. I was first introduced to tooth
  remineralization a few years ago by a lonely webpage which
  talked about the chemistry of the teeth, how enamal is
  continuously created, eaten away, and restored when your saliva
  is in an alkaline state and you are breathing. I experimented
  with sucking on magnesium tablets, calcium tablets, flouride
  rinses and found my teeth rejuvinating very quickly. I even
  managed to get a dental cary at the base of my gumline to go
  from black to white in a matter of days as new enamel formed
  over the old rot spot. The author of this book does such an
  amazing job explaining the chemistry of teeth, analogizes the
  enamel to the toughness an eggshell, and talks about the
  dangerous practices people use on a regular basis thinking their
  helping but are in fact HURTING their teeth. The program is
  simple, cheap and very easy to do. As soon as I get to the
  drugstore, I'll be picking up the things mentioned in the book,
  and I've already ordered some xylitol products via amazon. I've
  got some nasty tooth work ahead of me, and I'm going to try to
  improve things to see if I can avoid the expensive procedures
  they have in store for me. I'll let you know how it progresses.
