Fluoride Varnish

Fluoride varnish is a commonly used dental treatment that plays a crucial role in maintaining healthy teeth and preventing tooth decay. It’s a thin, protective coating that’s applied to the teeth, and contains a high concentration of fluoride. Fluoride is a mineral that strengthens tooth enamel and makes it more resistant to decay.

Fluoride varnish protects young teeth

Typically used for children, and adults in danger of developing cavities, fluoride varnish protects the teeth by remineralising weakened areas of the enamel. It also helps to reduce sensitivity and can even reverse early signs of decay. It’s a quick and painless procedure that can be done during a routine dental visit. Regular application of the varnish can help reduce the need for more invasive dental procedures in the future.



  • The length of time that the varnish should stay on the teeth depends on several factors, including the type of varnish used, and the age and dental health of the patient. Generally, fluoride varnish is left on the teeth for anywhere from 4 to 12 hours after application.

  • The varnish goes into the tooth enamel to harden it. It can slow down the spread of existing tooth decay and, in mild cases, even potentially repair the damage.

  • The varnish is painted directly onto the teeth using a brush. It becomes hard almost immediately.

  • You may be able to see it, but it still disappear after you’ve brushed your teeth the next day.

  • Swallowing the varnish can cause minor side effects such as stomach upset, nausea, and vomiting, but it is also highly unlikely that it will be swallowed.

“Dr Laura Mazecaite has gone above and beyond to help my daughter and to reassure her during our appointments. She gave my daughter her time, kindness and confidence to help reach the point where the idea of the treatment was acceptable – this is HUGE progress and I want to credit Laura for her patient, respectful and understanding care. I wouldn’t hesitate to recommend Laura to anyone in need of dental care. We are so grateful to have her as our dentist.”
