Child Brushes First, Parent Finishes: Tips for When Kids Start Brushing

Kids who grab the toothbrush still can't brush well alone. The child-first, parent-finishes routine, tips for 2 minutes, and why to keep it up to age 7 or 8.

"Me! I want to do it!" When your child starts demanding the toothbrush, it's exciting, but it also raises questions. If you let them brush alone, you're not sure the teeth are clean. If you do it yourself, your child protests. Here's the "child brushes first, parent finishes" approach, which keeps your child motivated and the teeth clean.

They want to try, but it's still hard

Around 30 months, kids start grabbing the toothbrush and copying what grown-ups do. Wanting to do it themselves is the start of a great habit. But no child this age can brush well on their own.

Brushing is more delicate than it looks. You need to change the angle of the brush to reach the back molars and the tongue side, and gently clean along the gum line. Kids usually just rub the fronts of the front teeth they can see, or chew on the brush and taste the toothpaste and call it done. Until their hand skills catch up, food and plaque (the sticky film of bacteria on teeth) are likely to stay behind in the back, even when it looks like they brushed.

So the order matters. Your child brushes first, and a parent always finishes. Until hand skills catch up, around age 7 or 8, your finishing pass is needed. Even if your child seems to do a good job alone, keep up the finishing pass until then.

Here are some common mistakes at this stage.

• Stopping when your child says "Done!" Your child's brushing is practice. The finishing pass is the real brushing.
• Letting your child squeeze out the toothpaste. The amount quickly gets too big.
• Turning brushing into a time for scolding. When brushing feels like a bad thing, the pushback gets worse.
• Skipping bedtime brushing on tired days. Saliva drops during sleep, so the mouth isn't rinsed as well. That makes it the most important brushing of the day.

Brush together in this order

1. Brush twice a day at set times. Brush in the morning and before bed, and never skip bedtime brushing.
2. Squeeze out the toothpaste yourself. Use a rice-grain smear of fluoride toothpaste, and a pea-sized amount from the third birthday. When kids squeeze it, it's easy to use too much.
3. Let your child brush first, for about 1 minute. Give lots of praise. The goal isn't brushing well, it's the experience of doing it themselves.
4. Go over every surface yourself. Setting an order keeps you from missing spots. For example, start on the outside of the upper right teeth, go all the way around, then do the bottom the same way. Brush the chewing surfaces, cheek sides, and tongue sides.
5. Make 2 minutes easy to see. Playing the app's brushing timer or a toothbrushing song lets your child know when it'll be over, so they fight less.

For the finishing pass, lay your child in your lap with their head toward you. You'll see inside the mouth better, and most kids settle. If your child gets bigger and doesn't want to lie down, you can stand behind them and let their head rest against your body while you brush.

When your child refuses the finishing pass, try these.

• Offer small choices, like picking one of two toothbrushes.
• Brush a stuffed animal's teeth first, then say "Now it's your turn."
• Make it a game, like "Let's find the cracker crumbs hiding in your molars!"
• On days when brushing doesn't go well, skip the scolding and calmly carry on at the next brushing.
