What is topical fluoride used for in dental care?

Topical fluoride is primarily used in dental care to strengthen tooth enamel and reduce the risk of cavities. It works by remineralizing enamel that may have begun to demineralize due to acid attacks from bacterial plaque. When fluoride is applied topically, it helps in making the teeth more resistant to decay by enhancing the enamel's hardness. This prevention strategy is crucial in promoting long-term dental health, particularly in children and adolescents, as their teeth are still developing.

The other options do not accurately represent the primary use of topical fluoride. Whiten teeth is not a function of topical fluoride; instead, whitening agents specifically target discoloration. While fluoride can have some beneficial effects on gum health as part of a comprehensive oral hygiene strategy, its primary action is not to treat gum disease. Additionally, sedation does not fall under the scope of topical fluoride application, which is focused on preventive care rather than managing patient anxiety or pain during dental procedures.
