I have heard that Xylitol actually helps to prevent tooth decay. Is that right?

In studies over more than 30 years, dental researches have pointed to Xylitol as a key ingredient in helping to protect against tooth decay. In fact it is extensively used in many oral hygiene products. Many health professionals in Europe have been using Xylitol since the 1970’s – in particular the Finnish government is thought to have saved millions of dollars by using Xylitol in its health programs.
