What does topical fluoride refer to?

Topical fluoride refers specifically to fluoride that is applied directly to the surfaces of the teeth. This form of fluoride helps to strengthen tooth enamel and can provide protection against cavities and decay. By being applied topically, either through treatments at the dentist's office or through the use of fluoride toothpaste and mouth rinses at home, it allows for a direct benefit to the areas that are most at risk for developing dental issues.

In contrast, the other options describe forms of fluoride that do not involve direct application to the teeth. Oral administration of fluoride is different from topical application, as it is absorbed into the bloodstream and not applied directly to the teeth. Similarly, fluoride consumed in food or produced by bacteria does not provide the same targeted benefits for dental health as topical fluoride does. Thus, option B accurately reflects the nature and use of topical fluoride in dental care.
