Fluoride is a mineral that helps enamel stand up to cavities.

In kid words

"Fluoride is a little helper in your toothpaste that makes your teeth stronger." Say it the same easy way you would talk about vitamins in food. Sometimes at a checkup we paint a bit more of it onto your teeth with a tiny brush, and it comes in a flavor you get to pick.

The parent version

Fluoride is a naturally occurring mineral that helps strengthen tooth enamel and makes it more resistant to the acid that causes cavities. It occurs in small amounts in water and soil, and it has been added to toothpaste and many community water supplies for decades. The American Dental Association and the American Academy of Pediatric Dentistry both include fluoride as a standard part of mainstream cavity prevention.

At home, the American Dental Association's general guidance is a rice-grain smear of fluoride toothpaste before age 3, and a pea-size amount after, with an adult supervising. What routine actually fits your own child is still worth confirming, so ask your pediatric dentist.

Where you might hear it at our office

Fluoride comes up at an ordinary preventative care visit, usually as a varnish painted on with a small brush toward the end of a cleaning. It sets quickly and is one of the shortest parts of the whole appointment.

Whether a fluoride treatment fits your child's plan, and how often, is worked out with your pediatric dentist based on their own teeth and history, not a one-size rule. If another word from today's visit is still a mystery, the rest of the dictionary is right here.
