Fluoride and Your Child's Smile: A Parent's Guide

Fluoride is one of the best tools for protecting your child's developing teeth, but as a parent you may wonder how much they need and whether it is safe. The answer comes down to using the right amount at the right age. Here is a clear guide for Kingman families.

How fluoride helps kids

Fluoride strengthens tooth enamel and helps it resist the acids that cause cavities. For children, whose teeth are still developing, it offers lasting protection and can even reverse the earliest signs of decay. It is a big reason childhood cavities have declined over the decades.

How much toothpaste by age

• Under age three: a tiny smear about the size of a grain of rice
• Ages three to six: a pea-sized amount
• Always supervise brushing so your child spits rather than swallows

Other sources of fluoride

Besides toothpaste, children may get fluoride from many community water supplies and from professional treatments at the dentist, such as a quick fluoride varnish applied at checkups. Together these provide steady, low-level protection.

A note on safety

At recommended amounts, fluoride is safe and effective. The main thing to watch is young children swallowing too much toothpaste while their teeth are forming, which can cause faint white spots called fluorosis. Using the correct amount and supervising brushing prevents this.

When in doubt, ask
