Fluoride treatment
Fluoride strengthens tooth enamel and helps it resist the acids that cause cavities. A professional application takes a few minutes at the end of a cleaning.
Who benefits
Children while their teeth are developing, and adults with a history of cavities, dry mouth, gum recession or sensitive teeth.
What to expect
A fluoride varnish is brushed onto the teeth. It sets on contact, and we will tell you how long to wait before eating or brushing.

How it works
How fluoride is applied
The simplest protection we offer.
1Your teeth are cleaned
Fluoride works best on clean teeth, so it follows your cleaning.
2The varnish is brushed on
A thin coat is painted on every tooth in a minute or two.
3It keeps working
The varnish stays on the teeth for a few hours while the enamel takes it up.
