I’ve had parents cry in my clinic about toothbrushing. Not about cavities — about the fight. Two minutes, twice a day, and somehow it becomes the worst part of the day for everyone in the house.

So let’s separate two things: what actually has to happen, and how you get there. The first list is short and non-negotiable. The second is where all the flexibility lives.

The part that isn’t negotiable

  • Twice a day, and one of those times is the last thing before bed — after the last food or drink of the day.
  • Fluoride toothpaste, every time. A rice-grain smear under three, a pea from three to six, a full brush after six.
  • Spit, don’t rinse. No water, no cup, no swishing. The thin film of toothpaste left behind is doing the work for the next half hour.
  • An adult brushes, or finishes brushing, until about seven. Children don’t have the fine motor control before then, no matter how capable they look.
  • Floss once a day from the moment two teeth touch — a brush physically cannot reach between them.

Everything below is about how to get those five things to happen without a nightly battle.

Why it’s a fight in the first place

It helps to know you’re not being defied. A toddler resisting the toothbrush is usually dealing with one of three things: autonomy (this is one of the few parts of their day they can control), sensory discomfort (the mouth is an intensely sensitive place and mint is genuinely unpleasant to many children), or timing (you are asking an exhausted person to hold still).

None of those respond well to more force. All of them respond to design.

Six things that work

1. Anchor it to the same two moments, every single day

Not “after dinner sometime” — immediately after pyjamas, before the story, every night. Children argue with decisions. They rarely argue with routines that have simply always existed.

2. Fix the position before you fix the attitude

Standing in front of a toddler and coming at their face is the hardest possible angle, for you and for them. Instead, stand or sit behind them and tilt their head back against your body — or, for little ones, lie them on your lap with their head towards you. You can see every surface, and your hand moves the way it does on your own teeth.

3. Let them go first, then check for sugar bugs

Give them the brush. Let them have their turn, badly, for as long as they want. Then: “my turn to check for sugar bugs at the back.” They get the autonomy; you get the actual cleaning. This single swap fixes more households than anything else I suggest.

4. Offer real choices — never the choice

Which toothbrush, which flavour, which song, bathroom or bedroom, standing or lying, you first or me first. What is never on the table is whether brushing happens at all. Choice defuses a power struggle; a question invites one.

5. Give two minutes a container

Two minutes is an eternity to a three-year-old with no way to measure it. A song they know, a sand timer, a brushing app, counting teeth out loud in fours — anything that turns an open-ended ordeal into a thing with a visible end.

6. Narrate everything, negotiate nothing

We use “tell, show, do” in the clinic and it works just as well at the bathroom sink. Say what’s about to happen, show it on a toy or on your own teeth, then do it — calmly, at the same speed, whether or not there’s complaining. Confidence is contagious. So is hesitation.

The amounts, precisely
  • First tooth to 3 years: a smear the size of a grain of rice, fluoride 1000 ppm or more.
  • 3 to 6 years: a pea-sized amount, 1000–1450 ppm.
  • 6 years and up: a full brush head, 1450 ppm.
  • Spit out. Don’t rinse. Supervise until around seven.

Three things that don’t

Bribing with something sweet

It teaches that brushing is a price you pay for sugar, and it usually adds one more sugar exposure right at the end of the day. Rewards work — stickers, a chart, an extra story, choosing tomorrow’s song. Sweets undo the thing you just did.

“If you don’t brush, the dentist will drill your teeth”

I understand why it’s tempting. But the child who arrives in my chair believing I am a punishment for bad behaviour is far harder to treat, and stays harder for years. Please don’t hand me to your child as a threat — I’d much rather be the person who counts their teeth and gives out stickers.

Skipping the night brush “just this once”

Saliva flow drops during sleep, so whatever is left on the teeth at bedtime sits there for eight or nine hours with nothing to wash it away. The night brush is the one that matters most, and “just this once” has an unfortunate habit of becoming three nights a week.

A boring ninety seconds every single night beats a brilliant three minutes on Sundays.

If your child is autistic, or sensitive to touch, taste or sound

Standard advice often doesn’t transfer, and that isn’t a failure. Things that help: an unflavoured or very mild toothpaste, a visual schedule with photos of each step, the same order of teeth every time so nothing is a surprise, letting your child hold the brush handle with you, brushing somewhere other than the bathroom, choosing a calmer time of day than bedtime, and trying a vibrating brush — or firmly avoiding one, because for some children the buzz is the problem.

Tell us before the appointment and we’ll book a longer, quieter slot, keep the lights down, and go entirely at your child’s pace.

When to call instead of trying harder

  • Gums that still bleed after two weeks of genuinely good brushing.
  • Any white, chalky or brown patch — especially along the gumline.
  • A child who suddenly refuses after months of cooperating; that’s often pain, not attitude.
  • Bad breath that doesn’t clear with brushing.
