How much is fluoride varnish in London?

Fluoride varnish at Sure Smile Clinic starts from £25 and is often included as part of routine children's dental care.

Does fluoride varnish hurt?

Not at all. It is simply painted onto the tooth surface with a tiny brush and sets within seconds — no drilling and no injection.

How often should it be applied?

Twice a year for most children and adults. Patients at high risk of decay may benefit from three or four applications a year.

Can adults have fluoride varnish?

Yes. It is particularly useful for adults with sensitivity, gum recession, dry mouth or a history of frequent fillings.

What should we avoid afterwards?

Avoid hot drinks, hard or crunchy food and vigorous brushing for the rest of the day so the varnish stays in contact with the enamel.

How it is applied

Teeth are dried, the varnish is brushed on with a small applicator and sets straight away. There is no injection and nothing to hold in your mouth. We ask you to avoid hot drinks and hard brushing for a few hours so the fluoride has time to work.

Is fluoride safe?

Yes — professionally applied varnish is safe and strongly supported by evidence, including guidance in the NHS Delivering Better Oral Health toolkit. The dose is tiny and controlled. We check for allergies to colophony and adjust for very young children or those with severe asthma.
