What is the main purpose of fluoride treatments?

The main purpose of fluoride treatments is to enhance the enamel's resistance to decay. Fluoride works by remineralizing tooth enamel, making it more resistant to acid attacks from bacteria in the mouth. This process helps to prevent the formation of cavities and can even reverse early stages of tooth decay.

Fluoride strengthens the mineral composition of the enamel, effectively fortifying the teeth against the demineralizing effects of dietary sugars and acids. Regular fluoride treatments can be particularly beneficial for individuals at higher risk for cavities, making them an essential part of preventive dental care.

Other options focus on different aspects of dental and oral health that do not align with the primary function of fluoride treatments. For instance, lightening the color of teeth pertains to cosmetic whitening procedures rather than decay prevention, reducing gum sensitivity relates to managing gum health rather than strengthening enamel, and replacing missing teeth involves restorative procedures that do not involve fluoride's role in preventing cavities.
