Fluoride Varnish

Fluoride Varnish is a highly concentrated form of fluoride which is applied to the tooth’s surface as a type of topical fluoride therapy. It is not a permanent varnish, but due to its adherent nature, it is able to stay in contact with the tooth surface for several hours.

Indications for use:

  • For patients with a moderate to high risk for tooth decay, especially children 6 years and younger
  • Desensitizing agent for exposed root surfaces
  • Decay prevention for exposed root surfaces
  • Fluoride application around orthodontic bands and brackets
  • Fluoride treatment on patients where there is a concern that a fluoride rinse, gel, or foam might be swallowed

Advantages:

  • The fluoride varnish does not have the bitter taste of some fluoride gels
  • They are quickly and easily applied, as it sets rapidly in the presence of saliva
  • Varnish contains xylitol to increase cavity prevention
  • They are suitable for patients with a strong gag reflex, because they are quickly applied and do not require fluoride trays
  • The varnish has a sticky consistency which helps it to adhere to the tooth’s surface, thereby allowing the fluoride to stay in contact with the tooth for several hours
  • Based on published findings, professionally applied fluoride varnish does not appear to be a risk factor for dental fluorosis, even in children under the age of six. This is due to the reduction in the amount of fluoride which may potentially be swallowed during the fluoride treatment, the small quantities used, and the adherence of the varnish to the teeth
  • The newest product on the market does not discolour teeth or dental restorations during application. At one time you would have expected a temporary yellow/brown stain but this is no longer the case
