For children, the best technique is simple, gentle, and parent-supervised.
Tooth brushing technique for children
1. Use the right brush and toothpaste
Use a soft, small-headed child toothbrush. Brush twice daily, especially before bed. Start brushing as soon as the first tooth erupts. For toothpaste: use a rice-grain smear of fluoride toothpaste for children under 3, and a pea-sized amount from age 3 to 6.
2. Position the child well
For toddlers, stand or sit behind the child, gently support the chin, and brush while looking into the mouth. For infants, you can lay the child on your lap.
3. Brush at the gumline
Place the bristles at about 45 degrees toward the gumline. Use small circular motions or tiny back-and-forth wiggles. Avoid hard scrubbing.
4. Follow a sequence
Brush all surfaces:
- Outer surfaces
- Inner surfaces
- Chewing surfaces
- Behind the front teeth
- Along the gumline
Aim for about 2 minutes, but for very young children, thoroughness matters more than timing.
5. Spit, don’t rinse
Teach the child to spit out excess toothpaste. They do not need to rinse with water, because leaving a little fluoride on the teeth helps protect against decay.
6. Parent help is essential
Young children usually cannot brush effectively by themselves. Parents should brush for them or supervise/finish brushing until they develop good hand control, often around 7–8 years old.
Easy instruction for parents
“Brush in tiny circles, touching the gums, every morning and night. Use only a rice-sized smear under 3 years old, and a pea-sized amount after 3. Let the child spit, but don’t rinse.”
For children with high caries risk, bleeding gums, crowding, braces, or poor cooperation, the technique may need to be modified.
