How much toothpaste, and which kind?
| Age | Fluoride toothpaste amount |
|---|---|
| First tooth to age 3 | A smear, about the size of a grain of rice |
| Ages 3 to 6 | A pea-sized amount |
Fluoride is what makes toothpaste protective, so choose one that contains it. Our toothpaste buying guide goes deeper on flavors and labels. The small amounts above keep the swallowed portion low while still protecting enamel.
The step-by-step technique
- Get in position. For young toddlers, sit knee-to-knee with another adult, or lay your child’s head in your lap facing up. For older toddlers, stand behind them at the mirror and cradle the chin.
- Wet the brush and add the smear. Use a soft brush sized for small mouths.
- Tilt the bristles toward the gums. Angle about 45 degrees and use small, gentle circles, not scrubbing.
- Cover every surface. Outsides, insides, and the chewing surfaces of each tooth. Molars have grooves where food hides.
- Brush along the gumline. That is where plaque tends to collect first.
- Spit, don’t rinse. Encourage spitting out the extra foam. Skipping the rinse leaves a little fluoride on the teeth to keep working.
Two minutes is the target, but honestly, a thorough 60 seconds every night beats a heroic two minutes once a week. Build up as your child gets used to it.
Knee-to-knee, step by step
The knee-to-knee position is what pediatric dentists use with little ones, and it works well at home:
- You and another adult sit facing each other, knees touching.
- Your child sits facing the first adult, with legs around their waist, and lies back with head on the second adult’s knees.
- The second adult has clear sight of the teeth and steady access, and your child gets to look at a familiar face.
- If you’re solo, a lap and a bathroom mirror or a nearby toy can do the same job.
Making it a routine (without a nightly battle)
Same time, same order
Brushing right after pajamas and before the story creates a pattern. Kids resist less when they know what’s next.
Let them go first
Give your toddler the brush for 20 seconds to explore, then say “my turn” and finish the job.
Sing, count, or use a song
A short favorite tune gives you a natural timer and takes attention off the brush.
Narrate the fun
Silly narration works: “Now the front teeth… now the ones way in back…” keeps the mouth open and the mind busy.
Model it
Kids copy what they see. Brush next to them when you can.
Pick your battles
If bedtime is a meltdown, brush earlier and save story time as the reward.
When your toddler simply refuses
This phase is normal, and most families find a rhythm within a few weeks. If you’re in the middle of it, try these:
- Brush for as long as they’ll allow, then try again a few hours later. Something is better than nothing.
- Let them pick a brush with a favorite character or color, and a toothpaste flavor that isn’t too spicy.
- Brush at a different time or place, for instance, on the changing table or on the bed.
- Stay calm. Frustration tends to make the mouth close tighter.
- Ask us for a demonstration. Watching hands-on technique can help your child and you.
When do I need a dentist for this?
Brush at home, and have your child seen by their first birthday for a check-up. Our kids’ cleanings and checkups are built around toddler-friendly pacing, and we’re happy to show you technique. If you see white or brown spots, or your toddler complains of tooth pain, contact us sooner. Fluoride varnish from the dentist can add extra protection, which you can read more about on our fluoride treatments page.
Beaverton and Aloha families who’d like coaching on brushing, or who feel stuck, can request an appointment and mention “brushing help” so we can plan time for it.
Toothbrush basics
Choose a soft-bristled brush with a small head and a handle that’s easy for you to grip, since you’re the one doing the brushing. Replace it about every three months, or sooner if the bristles splay out or after your child has been sick. Electric brushes are fine for toddlers if they tolerate the vibration; a quiet manual brush is equally good in the right hands. What matters most is time and thoroughness, not price.
Flossing, too?
Once two teeth touch, floss between them once a day. Floss picks with a small handle are often easier than string for small hands and small mouths. If you’re unsure how to do it, ask at your child’s next visit and we’ll show you.
A word on bedtime
Nighttime brushing is the most important brush of the day, because saliva flow drops during sleep and leftover food and sugar sit on the teeth longer. After the last brush, only water until morning. If your toddler is a wanderer at bedtime, brushing right before the story rather than after keeps that rule easy to follow.
