Which dental practice helps to prevent the development of cavities?

Fluoride treatments are an effective preventive measure against cavities. Fluoride is a naturally occurring mineral that strengthens tooth enamel and makes it more resistant to acid attacks from plaque bacteria and sugars in the mouth. When applied topically through treatments or incorporated into dental hygiene products such as toothpaste and mouth rinses, fluoride helps to remineralize weakened areas of enamel before they develop into full-blown cavities. This preventive approach is supported by extensive research, demonstrating that fluoride can significantly reduce the incidence of dental caries in both children and adults.

In contrast, root canal therapy, extractions, and veneer placement are restorative and corrective treatments rather than preventive measures. Root canal therapy is used to treat an infected or damaged tooth, while extractions may be necessary for teeth that are beyond repair. Veneer placement is a cosmetic procedure aimed at improving the appearance of teeth, but it does not address cavity prevention directly. These practices focus on addressing existing dental issues rather than protecting against the formation of cavities.
