Topical fluoride is a mineral that helps strengthen tooth enamel and prevent cavities. It is commonly found in toothpaste and mouth rinses, and can also be applied by dental professionals in the form of gels, foams, or varnishes. When applied directly to the teeth, it enhances the remineralization process, making teeth more resistant to decay. Using topical fluoride is especially beneficial for children, as their teeth are still developing. It can also be helpful for adults at higher risk of cavities due to factors like dry mouth or gum disease. Regular use of topical fluoride contributes to overall dental health and hygiene.
