How fluoride treatment helps your teeth
Fluoride makes tooth enamel stronger and better able to resist the acid that plaque bacteria produce after you eat or drink something sugary. It also helps early decay, which often looks like a chalky white spot, harden again before it turns into a cavity.
The varnish or gel your dentist uses holds much more fluoride than toothpaste. It is painted on clean teeth in a few minutes and stays on the teeth for a while afterward, which is why the aftercare steps on this page matter.
For children, fluoride treatment is one of the simple ways to lower the risk of cavities in both baby and adult teeth. Your dentist suggests how often based on your child's risk of decay, usually at regular check-ups.
Who fluoride treatment can help
- Children, while their teeth are developing.
- Adults who get cavities often, or have early decay or white spots.
- People with a dry mouth, braces, or exposed roots from gum recession.
Fluoride helps but does not prevent every cavity, so brushing, cleaning between the teeth and a healthy diet still matter.
Due for a check-up?
Book a check-up and cleaning. Your dentist checks your teeth and gums and tells you if anything else needs attention before treatment.
What happens
Check-up and cleaning
Your dentist checks and cleans the teeth so the fluoride can reach the enamel.
Applying fluoride
A fluoride varnish or gel is painted or placed on the teeth. It takes only a few minutes.
After fluoride treatment
Avoid eating and drinking for about 30 minutes, or as your dentist advises. If a child needs to eat after a varnish, give soft food and avoid hot food and drinks. Your dentist tells you when your child can brush again.
Cost of fluoride treatment
Fluoride treatment is usually done with a check-up and cleaning. Your dentist confirms the fee before treatment, and the prices page lists our cleaning and prevention fees.
Prices on our prices page are shown as ranges. Your final fee depends on what the examination finds, and may include additional items — such as a rubber dam or special materials — when your treatment needs them. Your dentist explains these before treatment.
Fluoride FAQs
Is fluoride varnish safe for children?
Yes. Fluoride varnish is widely used by dentists to help prevent decay in children. Only a small amount is applied, and it is not meant to be swallowed.
How much fluoride toothpaste should my child use?
Under three: a thin smear, about the size of a grain of rice, with an adult brushing. From three to six: a pea-sized amount. Teach children to spit out, not swallow, the toothpaste.
What is fluorosis?
Fluorosis is white or brown marking on the teeth caused by swallowing too much fluoride while the adult teeth are forming in early childhood. Using the right amount of toothpaste and spitting it out helps prevent it.
Do adults need fluoride treatment?
Not every adult does. It helps adults who get cavities often, have early decay, a dry mouth, braces or exposed roots. Your dentist suggests it at your check-up if it would help.
How often should fluoride be applied?
Usually at regular check-ups, about every six months. Your dentist may suggest a different interval depending on your risk of decay.
How much does fluoride treatment cost?
It is usually done with a check-up and cleaning. Your dentist confirms the fee before treatment, and the prices page lists our cleaning and prevention fees.
