fluoride
Definition
Fluoride is a mineral that is found in nature. It is also added to water and toothpaste to help prevent tooth decay.

Fluoride can also help to repair early signs of tooth decay. This is why it is important to brush your teeth with fluoride toothpaste and to drink fluoridated water.
