Topical fluoride can be applied by your dentist’s office in two ways: as a gel (which is the more traditional method) or as a varnish. Topical fluoride varnish is relatively new in the United States, but it has been commonly used in other parts of the world. Basically, the varnish is a coating that is “painted” on the enamel of teeth, and it allows the fluoride to be absorbed. It is generally applied at a routine dental cleaning appointment, and it is especially useful for young kids and kids who have difficulty with the traditional fluoride trays.

According to the American Academy of Pediatric Dentistry, “using fluoride for the prevention and control of cavities is documented to be both safe and highly effective.” Fluoride varnish has made this useful tool easier to apply to the teeth of young kids. Fluoride varnish sets quickly, is easy to apply, and adheres to the teeth for a longer period. Next time your young children are at the dentist, ask about fluoride varnish.
