Tooth Town Street Sweeper

The mouth becomes a little town with six streets, and the toothbrush is the street sweeper that must visit every one before the two-minute timer runs out.

  1. Draw the map. On a piece of paper, draw a big smile with a top row and a bottom row of teeth. Divide each row into three “streets” — left, front, right. Stick it by the mirror.
  2. Load the sweeper. The child squeezes on a pea-sized dab of fluoride toothpaste. Show a real dried pea or draw one so they know how small that is.
  3. Start the timer — a two-minute sand timer, a kitchen timer, or one favourite song.
  4. Sweep street by street. About 20 seconds per street, using small gentle circles. On each street sweep the outside (cheek side), the inside (tongue side), and the tops (chewing surfaces). The child points to the street on the map with their free hand, or you call it out — “Now Top Left Street!”
  5. Finish with the tongue — a few gentle sweeps — then spit the foam out.
  6. Grown-up inspection. You are the town inspector — look in with a “torch” (phone light), then do a quick finishing brush of your own, especially the back molars and along the gumline. Tell them one street they swept really well.

Variation: let the child brush your teeth, or a doll’s, while naming the streets — teaching the route is a great way to learn it. For an occasional eye-opener, use a plaque-disclosing tablet (sold in pharmacies; follow the pack’s age guidance) before brushing so the child can see the colour that marks where the sweeper needs to go.

Requirements

  • Space: The bathroom, in front of a mirror the child can see into
  • Surface: A sturdy, non-slip step stool if needed so the child can see their own mouth in the mirror
  • Materials: Child-sized soft toothbrush, fluoride toothpaste, a two-minute timer or song, paper and pen for the map, a cup
  • Participants: 1 adult + 1 child
  • Supervision: Close — an adult watches the whole brush and finishes off afterwards

Rationale & Objective

This subdomain’s measurement is “brushes teeth covering all areas with supervision only for checking.” The American Dental Association and the NHS both recommend brushing twice a day for about two minutes with a pea-sized amount of fluoride toothpaste from age three, and fluoride toothpaste is one of the best-evidenced ways of preventing decay in children (Marinho et al., Cochrane review). What five-year-olds typically lack is coverage and duration: left alone they brush the front teeth they can see for twenty seconds and stop. Research on brushing ability (Unkel et al., 1995) found that a child’s age is a reasonable predictor of how well they can brush — which fits the NHS advice to supervise brushing from ages three to six and to keep watching even after seven. Dividing the mouth into named zones turns a vague instruction (“brush properly”) into a route the child can remember and self-monitor, and the inspection step keeps the adult’s finishing brush as a friendly ritual rather than a correction. Motorically, reaching the inner surfaces demands wrist rotation and grip changes that also support fine motor development.

Progress Indicators

  • Early: brushes only the front teeth; chews or sucks the brush; stops after 20–30 seconds; needs the adult to guide the hand to each area
  • Developing: visits all six streets when they are called out; brushes outside surfaces well but forgets insides or chewing surfaces; keeps going for about a minute; spits out most of the foam
  • Proficient: follows the whole route from the map or from memory for the full two minutes; covers outside, inside, and tops on each street; uses a pea-sized amount without reminders; adult only needs to check and touch up
  • Advanced: starts brushing morning and evening with little prompting; angles the brush to reach the back molars and gumline; explains the route to someone else; notices by feel when a tooth still seems “fuzzy”

Safety Notes

  • Use only a pea-sized amount of fluoride toothpaste and teach spitting rather than swallowing; store the tube out of reach, as children are tempted to eat sweet-tasting paste
  • No walking, running, or climbing with a toothbrush in the mouth — falls with a brush can cause serious injuries to the mouth and throat. Feet stay planted at the sink
  • Use a soft-bristled, child-sized brush and gentle pressure; hard scrubbing can make gums sore
  • Loose baby teeth are common from around this age — brush gently around a wobbly tooth and never force it
  • If your child gags strongly, refuses brushing because of how it feels, or has bleeding gums, white or brown spots, or tooth pain, talk to your dentist; an occupational therapist can help with strong sensory aversion
  • If you use disclosing tablets, follow the age guidance on the pack, use them only occasionally, and expect lips and tongue to stay coloured for a while

Hints

  • Playfulness: give the streets names — Molar Mews, Front Tooth Avenue — and narrate the rubbish being swept up: “There’s a bit of breakfast hiding on Bottom Right Street!”
  • Sustain interest: redraw the map with a new theme each month (a zoo with six enclosures, a castle with six rooms), or let the child choose the two-minute song for the week
  • Common mistake: handing brushing over completely once the child “can do it.” They can do the motions long before they can do the job — keep the inspector’s finishing brush going for a couple more years
  • Limited space: no reachable mirror? Sit facing each other with a hand mirror, or brush side by side so the child copies your route like a mirror image
  • Cross-domain: left/right and top/bottom on the map build spatial vocabulary; counting ten circles per spot builds numeracy; estimating “is the sand halfway yet?” introduces time concepts
  • Progression: adult calls each street and guides the hand → child follows the map with reminders → child runs the route from memory with the timer → adult only inspects and touches up
