Hand your toddler a toothbrush and let them brush your teeth first. Open wide, make funny faces, and let them be in charge. Then swap: 'My turn now!' The novelty of brushing a grown-up's teeth is irresistible, and the turn-taking structure makes the handover to 'parent's turn' feel fair rather than forced. What was a nightly battle becomes a game both of you look forward to.
From our family
This one changed our bedtime routine completely. My son (nearly 3) now genuinely looks forward to brushing — my wife recently commented on how good his teeth look, and it’s entirely down to the turn-taking making it something he wants to do rather than something done to him.
Best for this moment
for calmer, lower-pressure moments, especially when you need an indoor option.
Parent tip
Start before you overthink it. No-prep activities work best when you begin while the moment is still recoverable.
What success looks like
A good outcome is a few minutes of engaged play, some back-and-forth with you, and a small sign of progress in fine motor.

Why it helps
Toddlers resist teeth brushing largely because it feels like something done to them rather than with them. Turn-taking restores autonomy — they experience both roles, which builds cooperation. The sensory discomfort of brushing is also easier to tolerate when preceded by the fun of being in charge. Over time, the routine becomes associated with connection rather than conflict.
Variations
Let your toddler brush in front of a mirror so they can watch themselves being the 'dentist.'
Add a timer or short song — whoever is being brushed has to keep their mouth open until it finishes.
Take turns brushing a stuffed animal's teeth first to ease into the routine.
Safety tips
Use a soft-bristled brush and supervise closely when your toddler brushes your teeth.
Keep toothpaste amounts small — a smear for under-threes, a pea-sized amount for older toddlers.
Never leave your toddler unattended with a toothbrush as they could poke themselves.
When to pause and seek extra support
Stop if your child becomes distressed, unsafe, or consistently frustrated by the activity. If play, behaviour, or development worries keep showing up across settings, check in with a qualified professional.
