Brush Teeth Timer for Kids: A Montessori Toothbrushing Routine

Two minutes is a long time to a three-year-old with a toothbrush. A visual timer shows them how long that is. In a Montessori home, the adult starts the timer and stands nearby, and the child does the brushing.

Toothbrushing as practical life

In Montessori education, everyday tasks like dressing, pouring and cleaning are called practical life. The American Montessori Society says "Practical Life activities are the activities of everyday life," and its home guide lists "brushing one's teeth" among them. AMS describes the child's inner plea as "Help me to do it alone!"

Toothbrushing fits well. It happens twice a day, the steps are always the same, and a young child can do most of them. The adult's job is to set up the space and then step back. The AMS guide puts it this way: "Try not to intervene or correct unless asked."

How long and how much

The American Dental Association "recommends brushing teeth twice a day for two minutes using a fluoride toothpaste."

For toothpaste amounts, the CDC's 2019 report on children's toothpaste use says:

The CDC also says to watch children younger than 6 brush, and to ask your doctor or dentist about fluoride toothpaste before age 2. The same report found that more than 38% of children aged 3 to 6 used more toothpaste than recommended, so it's worth checking what's on the brush.

A prepared bathroom

A Montessori-style bathroom is set up so a child can do the routine without asking for help. Greenspring Montessori School's guide to the bathroom puts the goal plainly: "prepare the home environment for toddlers to be as independent as possible." Its advice includes keeping "all necessary items within reach," a step stool and a suction-cup mirror.

For toothbrushing, it suggests a tray with a toothbrush, toothpaste, "a timer, and a small water glass." It also suggests portioning toothpaste into small containers at first instead of handing over the whole tube.

What that looks like at home:

• A sturdy step stool so your child can reach the sink and see the mirror.
• A mirror at their eye level, or a small suction-cup mirror low on the wall.
• A low shelf or tray with their toothbrush, toothpaste and a small cup.
• A towel on a hook they can reach.
• The timer where they can see it from the stool, out of splash range.

Starting the timer

You start the timer; the brushing is your child's job. In Montessori Visual Timer, the Brush Teeth quick timer is already set to two minutes. Tap it and your child brushes until the color is gone.

Some practical details:

• Decide on a PIN. If small fingers like to fiddle, set one. Auto-lock on start is on by default, so once brushing begins the timer you set can't be paused or changed without the PIN. The app stays locked afterwards, so you'll enter the PIN before the next session.
• Leave "Keep Screen Awake" on. It's on by default and only applies while a timer runs, so the clock doesn't go dark at the one-minute mark.
• Decide on sound. The alert plays until someone taps it, so tap the screen and your child rinses. If you'd rather a quiet ending, turn off Play Sound in settings.
• Keep the quick timer. The app holds four quick timers. Brush Teeth comes with it, so leave it in place if you use it twice a day.

A step-by-step toothbrushing routine

1. Step up. Your child climbs onto the stool.
2. Get ready. Wet the toothbrush and put on the right amount of toothpaste for their age (or use one you've portioned out).
3. Start the timer. Tap Brush Teeth where your child can see it.
4. Brush. Top teeth, bottom teeth, fronts, backs and chewing surfaces, until the color is gone.
5. Stop the alert. Tap the screen when it plays.
6. Spit and rinse the brush. Put the brush back in its cup.
7. Your turn. For young children, finish with a quick check or a brush of your own, then let them wipe their face and hang the towel.

Keep the order the same morning and night. For the rest of the morning and bedtime routine, see our toddler routine chart.

When brushing is hard

Some children resist brushing whatever you try. A few things that may help:

• Practice when it's calm. Start the timer and let your child brush a doll's teeth first.
• Name what's left. "Half the color is gone. Now the bottom teeth."
• Keep it short and predictable. The timer ends at two minutes every time, so your child knows when it will stop.

If your child has sensory sensitivities, our guide to visual timers for kids with ADHD or autism covers quiet endings and transition warnings. If brushing stays a struggle, ask your child's dentist.
