Prevent dental decay with fluoride varnish

Our mouth contains bacteria that feeds on the sugars in the foods we eat and the beverages we drink. This produces acid that can wear away the hard, outer shell of your tooth (enamel). This can lead to cavities. Fluoride protects teeth by making your teeth stronger and more resistant to acid, not only reducing the risk of cavities but even helping to reverse the early signs of decay.

Unfortunately some children are more susceptible to cavities than others - genetics and salivary flow (how much saliva your child’s mouth is producing in a day) play a big role in this. In cases where, despite all parents’ and carers’ efforts, a child still has decay, fluoride varnish is applied by the dental care professional directly to the tooth surface to prevent cavities.

What is fluoride varnish?

This is a simple solution that can slow and prevent tooth decay in children, and Happy Kids Dental is your destination for effective, monitored fluoride treatment in London.

How does fluoride varnish prevent cavities?

Fluoride varnish leads to heavy remineralisation of the enamel surface, and subsequent acid attacks will allow fluoride ions to penetrate more deeply into the tooth structure. Varnishes like Duraphat® are useful because they stay on the tooth surface for some hours, allowing slow release of the fluoride ion.

Who should be having a fluoride varnish?

  • Children with a history of frequent cavities. If your child has one cavity every year or every other year, you might discuss with a paediatric dentist the need for a fluoride varnish.
  • Children with crowns. This treatment can put teeth at risk of decay at the point where the crown meets the underlying tooth structure.
  • Children with orthodontic appliances or braces. This treatment can put teeth at risk around the brackets of orthodontic appliances.

Fluoride varnish at Happy Kids Dental

At Happy Kids Dental, our paediatric team will recommend the right amount of fluoride for your child, as well as scheduling a regular fluoride varnish.

Fluoride varnish is a quick and simple procedure, which involves a gel being painted onto your child’s teeth using a soft brush. The gel has a fruity taste which temporarily colours the teeth for up to 3 days, before it gradually wears off.

We recommend fluoride varnish applications twice a year for all children above two years of age.
