The toothpaste manufacturers claim about their flouride containing toothpaste prevents the tooth decay. What does this flouride do to the tooth? Any chemistry?

Flouride has a chemistry which kills the bacteria,which stays as normal flora in teeth of human being.By lowering the numbers of bacteria we can slow down the decaying of teeth.

flouride combats the formation of tooth decay in 3 principle ways. 1. Flouride promotes tooth remineralization 2. Flouride can make a tooth more decay resistant. 3. Flouride can inhibit oral bacteria's ability to create acids. it is a very good thing for teeth for people of all ages.an exposure to flouride is the most effective cavity prevention treatment today available.
