Fluoride and fluoridation can help reduce tooth decay.

For the past 65 years, the publicly funded program that fluoridates water has helped many millions of Americans prevent and reduce tooth decay by 20-40%.  Fluoridation is one of the most effective ways to prevent dental decay.   In fact, a study showed that for every dollar spent in fluoridation, $38 dollars were saved in dental costs.  Fluoride is not only found in water, but also in toothpastes and certain mouthwashes.  Fluoride acts on the teeth by making them stronger so they can be more resistant to acid attacks.  Fluoride also repairs and remineralizes places of acid attacks.  This can help to reverse early cavities and prevent new ones from occurring.  For more information on Fluoride, please visit the American Dental Association.
