Topical Fluoride

Definition: Topical fluoride is fluoride applied directly to the teeth, as a varnish, gel or foam at the dental office or in toothpaste at home, to strengthen enamel and help prevent tooth decay.

Why it matters

Fluoride helps rebuild weakened enamel before a cavity forms. Families have different views on fluoride, so it is worth discussing the options, the amount used for young children and alternatives with your dentist.
