How Long Should Kids Brush Their Teeth? (And How Much Toothpaste)
SmartSmile Team
Quick answer: kids should brush twice a day for at least two minutes, with a parent supervising. That's the American Dental Association's advice. Use a smear the size of a grain of rice of fluoride toothpaste for children under 3, and a pea-sized amount for ages 3 to 6.
Toothpaste by age
| Age | Fluoride toothpaste amount | Who brushes |
|---|---|---|
| First tooth to 3 years | No more than a smear, about the size of a grain of rice | Parent brushes and supervises |
| 3 to 6 years | Pea-sized amount | Child brushes; parent supervises and reminds them not to swallow toothpaste |
| Older kids | Pea-sized amount | Child brushes, parent checks in |
Teach kids to spit out the toothpaste rather than swallow it. Ask your child's dentist about their specific needs. The American Dental Association recommends a first dental visit within six months of the first tooth appearing, and no later than the first birthday.
How to actually make it to two minutes
- Use a timer or music they enjoy. The ADA suggests upbeat songs, videos or brushing apps. Our free Brush Quest lets kids pick a buddy, follow the four quarters of the mouth, collect stars and badges, and earn a printable Brush Boss certificate.
- Let them choose the brush. A fun handle like the Paw Print or a brush that stands up on a suction cup gives them ownership.
- Brush together. Kids copy what they see.
- Track the streak. The Brush Quest keeps a 7-day streak on your device, with no account needed.
Which toothbrush for my child?
Choose a soft brush with a small head that fits their mouth. Check it regularly and replace it every 3–4 months, or sooner if the bristles are frayed. Kids who chew their brush may need a new one sooner.
FAQ
My child hates brushing. What can I do?
Keep it short, positive and routine: same time, same place. Make it a game with a song or timer, and celebrate the streak. If brushing is painful for them, check with your dentist.
