Fluoride varnish is a concentrated fluoride treatment applied to children’s teeth during well-child visits. It looks like a pale yellow or clear varnish and is painted on the teeth with a small brush in about one minute. The AAP recommends fluoride varnish starting at the first tooth eruption and applied every 3–6 months. It is safe, effective, and dramatically reduces the risk of tooth decay in young children.
Exciting news! We are now offering topical fluoride varnish treatments for young children! The American Academy of Pediatrics recommends that children have fluoride varnish applied to their teeth every 3-6 months starting when their first tooth appears. We are happy to offer this service as part of children’s check-ups! The varnish is painted onto each tooth with a small brush and quickly dries on the teeth. Dental health is so important and we love helping to keep kids’ teeth cavity-free!
As a reminder, the AAP also recommends brushing children’s teeth with a smear of fluoride toothpaste twice daily starting from the appearance of their first tooth. At 3 years old, it can be increased to a pea-sized amount of fluoride toothpaste. Happy brushing!
What is fluoride varnish and how does it work?
Fluoride varnish is a concentrated fluoride compound (usually 5% sodium fluoride) that is painted onto teeth. Once applied, it sets quickly on contact with saliva and releases fluoride over time, strengthening the outer layer of the tooth (enamel) and helping to repair early areas of decay. It is one of the most effective preventive treatments for early childhood cavities.
When does fluoride varnish get applied at Spring Valley Pediatrics?
Fluoride varnish is applied at well-child visits starting when your child’s first tooth erupts — even before their first dentist appointment. We typically apply it at the 6-, 9-, 12-, 18-, 24-, and 30-month visits, and annually thereafter until we recommend transitioning to regular dental visits. The AAP recommends fluoride varnish every 3–6 months for children at risk of tooth decay.
Is fluoride varnish safe for babies and young children?
Yes. Fluoride varnish has been used safely in children for decades and is recommended by the AAP, the American Academy of Pediatric Dentistry, and the CDC. The amount of fluoride used is very small, and most of it stays on the teeth rather than being swallowed. It is safe even for infants with their first teeth.
What should my child eat or drink after fluoride varnish is applied?
After fluoride varnish is applied, your child can eat and drink normally — soft foods and cool liquids are preferred for the rest of the day to give the fluoride maximum contact time. Avoid hot, hard, or sticky foods for a few hours. Do not brush your child’s teeth the night of the application, but resume normal brushing the next morning.
Does fluoride varnish replace going to the dentist?
No. Fluoride varnish at well-child visits is a preventive measure, not a substitute for dental care. The AAP recommends that children see a dentist by their first birthday. If your child has not yet established dental care, talk with your Spring Valley Pediatrics physician — we can help identify local pediatric dentists.
Does fluoride varnish change the color of teeth?
The varnish may give teeth a temporary yellowish or whitish appearance immediately after application, which fades within a few hours. It does not cause any permanent color change in teeth.
