What is Fluoride Varnish?
Fluoride is a naturally occurring element that is found in water, foods, and soil. When applied to the teeth, it can help to strengthen and repair the tooth enamel to prevent cavities. Fluoride varnish is a coating that is painted on teeth by a dental professional. Since it is sticky, it stays on the tooth longer than other fluoride treatments. The varnish can stick to a tooth, even when the tooth is wet from saliva. It dries almost immediately and provides long-term protection from cavities.
