Q: Can adults benefit from fluoride?

A: Topical fluoride is of benefit to cavity prone adults as well, especially for those who have had radiation to the head or neck, suffer from dry mouth, or have gum recession. Fluoride is also helpful for those with sensitive teeth. Topical fluoride preparations are available both with and without a prescription. Prescription fluoride preparations are stronger and are available as gels, rinses and may even be used in custom fabricated mouth trays for those at greatest risk of decay.
