Fluoride varnish is a treatment that dentists use to help protect teeth from sensitivity and cavities.
The varnish contains five percent sodium fluoride and, for application, it is painted directly on the teeth.
Fluoride varnish is commonly used on children because of its ability to help protect from cavities, an issue most prominent in children.
When used in congruence with everyday tooth brushing, fluoride varnish can also help reduce tooth decay.
After the varnish is applied onto the teeth by a dentist or professional health care provider, it should stay on the teeth for an extended period, several hours.

After that time, usually the next day, the fluoride varnish can be brushed off with a tooth brush and some fluoride toothpaste.
