Fluoride use in dentistry helps to prevent what?

Fluoride use in dentistry is primarily aimed at preventing caries formation, which is the development of cavities caused by the demineralization of tooth structure. When fluoride is applied to the teeth, it enhances the remineralization process of enamel and makes it more resistant to acid attacks from bacteria that produce acids as they metabolize sugars. This leads to a significant reduction in the rate of caries formation.

Fluoride works by integrating into the tooth structure and forming a stronger mineral that is less soluble in acid, thus providing a protective effect. Regular use of fluoride, whether through toothpaste, mouth rinses, or professional applications, is a key preventive strategy in dental practice. This underscores the importance of fluoride in maintaining oral health and preventing tooth decay throughout a person's life.
