How does fluoride protect teeth?

Fluoride is a natural anti-caries substance. Proper use of fluoride can protect teeth:

◆ Strengthen teeth and prevent dental caries;

◆ In the early stages of tooth decay, before a cavity is formed, fluoride can quickly replenish the lost minerals on the tooth surface, so that early demineralization can be repaired;

◆ Inhibit bacterial growth.
