Fluoride is one of the main active ingredients in nearly every toothpaste, and can sometimes be found in the water supply to help make teeth resistant to tooth decay.
Fluoride varnish uses a concentrated gel or liquid that is applied directly to the teeth, hardening and releasing fluoride into the enamel.
In this, it serves two purposes; along with releasing fluoride into the tooth gradually, it also provides a solid layer to directly protect teeth, in a similar way to the commonly used fissure sealant technique that fills in grooves and pits and makes teeth easier to clean.
It takes around ten minutes, and dentists tend to recommend waiting until the next morning before brushing teeth, as well as avoiding hot, crunchy, chewy and hard foods for the rest of the day.
Whilst it is a routine part of preventative dentistry for children, it can also sometimes be recommended for adults with chronic tooth decay, sensitive teeth or have damaged teeth from bruxism or other causes.
It is not a replacement for good oral hygiene, but it can be a highly effective aid to ensure teeth are as healthy for as long as possible.
