Fluoride applied to teeth helps prevent decay.
Fluoride varnish is temporarily adhesive form of fluoride applied to the tooth surface by a dentist, dental hygienist or other health care professional as a type of topical fluoride therapy. Fluoride varnish is not permanent, but is designed to adhere to the tooth surface and keep fluoride in contact with the tooth for several hours. Fluoride varnish may be applied to the enamel, dentine or cementum of the tooth and can be used to help prevent decay, remineralise the tooth surface and treat dentine sensitivity.
We apply fluoride varnish to all children's teeth between the ages of 4 and 18 years routinely at dental inspections. We also encourage patients to use fluoride toothpaste in the morning and evening and not to rinse out. Additionally if patients are susceptible to decay they will receive dietary advice and may be prescribed a higher fluoride toothpaste which will protect their teeth more thoroughly.
