Fluoride Treatments

Protecting Teeth with a Preventive Coating

Closeup of healthy smile Fluoride is a natural mineral found within the earth. Fluoride is also present in some foods that we eat, such as fish, and also present in our water supply. Fluoride has many benefits for your teeth, but studies have long shown the use of fluoride as an effective agent in reducing tooth decay. Fluoride prevents decay in both teeth that are currently formed as well as in teeth that are still forming in children's mouths. When teeth start to break down due to acid demineralization, fluoride can help strengthen the teeth and prevent the loss of enamel.

  • Are chemotherapy and radiotherapy patients
  • Take multiple medications
  • Have crowns
  • Have old fillings
  • Have a high sugar diet

  • Experience tooth sensitivity
  • Wear removable appliances

  • Have receding gums
  • Are undergoing orthodontic treatment

The only and BEST prevention for root cavities is fluoride, and the best and most reliable fluoride delivery is immediately after your cleaning. This is due to the natural biofilm layer that lies over the teeth, which your body will recoat with within 24 hours after your cleaning. The best time for fluoride is at the end of your cleaning since fluoride does not penetrate the biofilm layer well.

Not only does fluoride help prevent decay, it will also:

  • Kill bacteria within plaque and slow the colonization of pathogens
  • Reduce the volume of plaque
  • Decrease sensitivity

What is Fluoride Varnish?

Closeup of teeth during fluoride application

Fluoride varnish is a protective coating that is painted on teeth to help prevent new cavities and to help stop cavities that have already started.

The paint-on fluoride varnish is sticky, so it attaches to the teeth easily and makes the outer layer (enamel) of the teeth harder, helping to prevent cavities.

All patients who have had a lot of dental work in their mouth also can benefit from fluoride as it protects the margins of the dental work where decay can easily start again. Fluoride varnish can also reduce teeth sensitivity.
