Fluoride is a mineral that helps to strengthen teeth and prevent cavities. It is often added to toothpaste, mouthwash, and drinking water. Fluoride treatments can also be applied directly to the teeth by a dentist.
Fluoride treatments have been shown to be effective in preventing cavities in both children and adults. Children who receive fluoride treatments have a 40% lower risk of developing cavities than those who do not. Fluoride can also help to strengthen the teeth of adults and reduce the risk of root decay.
