A 30-second treatment with outsized benefits
Topical fluoride remineralizes early decay and makes enamel more resistant to acid. Professional fluoride varnish — applied at your cleaning — is more concentrated than what's in toothpaste, and lingers on teeth for hours.
It's especially valuable for kids whose adult teeth are still maturing, but adults with high cavity risk benefit too. Application takes about 30 seconds. Most insurance covers it.

Cleaning first
Applied after the cleaning to bond directly with enamel.

Common questions
Is fluoride safe?+
Yes, at recommended doses. Decades of research support both topical fluoride treatments and fluoridated drinking water as safe and effective.
How often do kids need it?+
Every 6 months with their routine cleaning. More often for high-decay-risk kids.
What about adults?+
Not routinely recommended for low-risk adults. For adults with dry mouth, frequent cavities or active orthodontics — yes.
