Re-activateOur dentist suggests that my husband and I receive topical fluoride treatments twice a year. Is that necessary? —A.C., Lawrence, Kan.
Extra fluoride may be helpful if you're at increased risk of developing cavities, indicated by frequent tooth decay in recent years, dry mouth caused by medications or disease, or gum recession that exposes the vulnerable tooth roots. But home treatments with a nonprescription fluoride rinse, such as ACTor Fluorigard, or a prescription gel or paste, such as Gel-Kam or PreviDent, may be adequate if your risk is only moderately elevated. If it's not elevated at all, brushing twice a day with a fluoridated toothpaste should supply enough fluoride, especially if your water is fluoridated.
