Prevention, Madison
Sealants and fluoride are two simple ways to help protect children teeth from cavities. Both take a few minutes, neither needs numbing, and the dentist will tell you whether your child is a good fit.
The idea
The best cavity is the one that never starts. Sealants cover the deep grooves where food hides, and fluoride helps make enamel stronger. Together with brushing, they do a lot of quiet work.
The visit
We show the little brush and the blue light, and let your child hold the light.
The tooth is cleaned and dried with a gentle puff of air. It can feel a little cool.
A thin liquid is painted into the grooves of the tooth. Children often say it tastes like nothing at all.
A small light makes the sealant set in a few seconds, tooth by tooth.
The dentist checks the sealant, and your child picks a sticker. Eating normally is usually fine right away.
Fluoride

A small amount of fluoride toothpaste, twice a day, is the everyday source.
Many communities add fluoride to tap water. Ask us if you use filtered or well water.
Too much is not better. We help you use the right amount for your child age and weight.

Good to know
Sealants and fluoride reduce the chance of cavities in the teeth they protect. They do not make teeth cavity-proof, and they do not replace brushing, flossing or a balanced diet. Results vary from child to child.
