Fluoride varnish is a highly concentrated form of fluoride which is applied to the tooth's surface, by a dentist, dental hygienist or other health care professional, as a type of topical fluoride therapy.
Fluoride varnish provides extra protection against tooth decay when used in addition to brushing. Fluoride varnish is a pale yellow gel that sets quickly when applied to children’s teeth using a soft brush. The varnish sets quickly, has a pleasant taste and a fruity smell.
Scientific studies have shown that fluoride varnish gives added protection to teeth against decay when used in addition to brushing teeth regularly with fluoride toothpaste.
Your child should be offered fluoride varnish application at least twice yearly from the age of two. This is applied to teeth at the dental practice by a member of the dental team.
You should let your dental practice know if fluoride varnish has recently been applied at nursery or school. This allows the dental practice to space out your child’s fluoride varnish applications to ensure maximum benefit.
