Fluoride Varnish

Fluoride varnish is a new way to deliver in-office fluoride treatment to patients, without the foam, gel or soft trays. It is easy to apply directly to the teeth, and is found to be extremely effective in the prevention of tooth decay. Because varnish adheres to the tooth surface for a longer time than other topical fluoride treatments, it is more effective and allows the tooth to uptake the mineral more efficiently.

Topical fluoride such as varnish is usually performed on children up to the age of 14. However, it can also be useful for older patients that have a history of recurrent dental decay, are undergoing orthodontic treatment, or suffer from tooth sensitivity. It is an effective therapy for tooth sensitivity and remineralization of tooth enamel.

Application of fluoride varnish is a little different than traditional methods, and is great for patients that have sensitive gag reflexes. Unlike other fluoride treatments, only a very small amount of varnish is used on each patient and it does not need to be held inside of the mouth for several minutes.  A small brush is used to distribute the thick gel across the teeth, which quickly spreads over the enamel and sets into a firmer consistency. The gel does appear as a slight yellow tint, leaving behind a very thin film on the surface of the teeth. This is only temporary and should be allowed to sit for at least 6 hours before brushing the teeth. However, after a varnish application there is no need to wait for food or drink after your dental appointment.
