This guide is for grown-ups choosing a toothpaste for kids around ages 3 to 8. It covers what to look for on the label, how much to use, and what to try when your child dislikes the taste. For toddlers under 3, see our toddler toothpaste guide. Your dentist can tell you what fits your child best.

Quick answer: what to look for in a kids toothpaste

If you are unsure, start with a toothpaste made for your child’s age and pick a flavor they like. A toothpaste your child is happy to use is easier to stick with every day.

Kids toothpaste (fruit flavors etc.)

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

How much toothpaste should kids use?

Kids tend to squeeze out far too much, so let a grown-up put the toothpaste on the brush. Teach your child to spit out the toothpaste instead of swallowing it.

Fluoride or fluoride-free?

Many dental organizations recommend fluoride toothpaste for children in age-appropriate amounts. Some families prefer fluoride-free options for their own reasons.

Because every child is different, ask your dentist which type and amount suits your child. Bring the toothpaste you use to the checkup so they can see the label.

When your kid hates the taste

In our home, finding a favorite toothbrush made a big difference. When kids help choose their tools, brushing feels more like their own thing.

Kids toothbrush (favorite character or color)

Picking it themselves makes brushing “their own thing”. Choose a head size that suits their age.

Make brushing time easier

Every day we put a sticker on the calendar after brushing, and it became a routine our child looks forward to.

Toothbrushing sand timer

A 2–3 minute sand timer for days without the phone or when traveling. It can sit by the sink.

Finishing toothbrush for parents

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

Ask your dentist

If your child has sensitive teeth, gum worries or trouble spitting, talk to your dentist before switching toothpastes. They can recommend the type and amount that fits your child.
