What impact does fluoride have on teeth?

Fluoride plays a crucial role in dental health primarily by strengthening tooth enamel. This mineral is incorporated into the structure of enamel, which is the hard outer layer of teeth, making it more resistant to decay. When fluoride is present, it enhances the remineralization process, which helps to repair early stages of tooth decay and can even reverse damage caused by acid-producing bacteria in the mouth.

Furthermore, fluoride can inhibit the activity of these bacteria, reducing the production of acids that lead to cavities. Regular exposure to fluoride through drinking water, toothpaste, and dental treatments can significantly lower the incidence of tooth decay, underscoring its importance in maintaining dental health over a lifetime. This strengthening effect is why fluoride is widely recommended as a preventive measure in oral care.
