Baby toothbrush: when to start and how to choose the best one for your baby

A baby’s first tooth is exciting, and it also raises a question: when do we start brushing, and what kind of toothbrush is right for such a small mouth?

This guide covers when to start, what to look for in a baby toothbrush, and a few tips for brushing calmly. Ask your child’s dentist or doctor about anything specific to your baby.

Quick answer: what to look for in a baby toothbrush

Toothbrush with a safety stopper

A stopper on the handle keeps the brush from going too far into the mouth. Handy when little ones want to hold it themselves.

Finishing toothbrush for parents

Long handle and small head make it easy for a grown-up to reach the back teeth.

When should a baby start using a toothbrush?

Many dental groups suggest cleaning the gums even before teeth come in, and starting to brush as soon as the first tooth appears, often around 6 months.

If a toothbrush still feels strange to your baby, you can start with a finger wipe or soft gauze, then add the toothbrush little by little.

Baby tooth wipes

Wrap one around a finger to wipe teeth and gums. Handy before a toothbrush feels OK, or when you are out.

Two brushes: one to hold, one to brush

Babies love to chew on a toothbrush. Letting them hold their own brush helps them get used to it, while a grown-up does the actual cleaning with a second brush.

In our family, when our child was little we used a kids toothbrush with a stopper on the handle, so it could not go too far into the mouth. It made it easier to let our child hold the brush while we watched.

How to brush a baby’s first teeth

Kids toothpaste (fruit flavors etc.)

A different flavor can change how much they resist. Check the age range and amount on the package.

Ask your dentist

A first dental visit is often suggested around the first tooth or first birthday. Bring your baby’s toothbrush and ask whether it fits well and how to brush at this age.

Turn brushing into an island adventure

Hamigaki Island is a kids app: during a two-minute brushing adventure, a boat sails around six islands, and lost baby teeth open new places to explore.
