Fluoride varnish and fissure sealants

  • Fissure sealants can be done once your child’s permanent back teeth have started to come through (usually at the age of about 6 or 7) to protect them against decay. This is where the chewing surfaces of the back teeth are covered with a special thin plastic coating to keep germs and food particles out of the grooves. The sealant can last for as long as 5 to 10 years.
  • Fluoride varnish can be applied to both baby teeth and adult teeth. It involves painting a varnish that contains high levels of fluoride onto the surface of the tooth every 6 months to prevent decay. Some children may need this more often. It works by strengthening tooth enamel, making it more resistant to decay.
  • From the age of 3, children should be offered fluoride varnish application at least twice a year. Younger children may also be offered this treatment if your dentist thinks they need it.
