Fluoride varnish

Fluoride varnish can be applied by dental teams at your family dental practice and at some nurseries and schools.

Fluoride varnish is a golden gel that is applied to a dried tooth surface. It has a pleasant taste and a fruity smell. It helps to prevent tooth decay by strengthening the teeth, and has shown to be most effective if applied to the teeth at least twice a year.

The varnish hardens on the tooth just after being applied, so the fluoride can be in contact with the outer surface of the teeth for a long period of time. The golden colour can take a few days to fade.
