Good brushing habits are one of the simplest, most powerful gifts you can give your child, and they almost always start at home, not in the dental chair. The challenge for busy Wimbledon families is turning a twice-daily chore into something children actually do well, and willingly. Here is our practical, no-nonsense guide to building brushing habits that genuinely stick.
Why early brushing habits matter so much
Tooth decay is still one of the most common, yet most preventable, conditions in children in England, and it remains a leading reason young children are admitted to hospital for extractions, according to NHS and Oral Health Foundation guidance. Milk teeth matter: they hold space for adult teeth, help with speech and chewing, and decay in them can be painful and disruptive to school and sleep. Habits formed before the age of seven tend to last for life, which is exactly why the early years are worth the effort.
The basics: how, when and with what
The NHS brushing advice for children is refreshingly straightforward. Start brushing as soon as the first tooth appears, and stick to these principles:
- Brush twice a day, last thing before bed and on one other occasion, for about two minutes each time.
- Use a fluoride toothpaste in the right amount for your child's age (see the table below).
- Spit, don't rinse. Spit out the toothpaste but skip the water afterwards, so the fluoride keeps protecting the teeth.
- Supervise until at least seven. Let your child have a go, then finish off the bits they have missed.
- Cut down on sugar, especially sugary drinks and snacks between meals, brushing can't outrun a high-sugar diet.
| Child's age | Toothpaste amount | Fluoride (ppm) | Who brushes |
|---|---|---|---|
| Under 3 years | A smear | At least 1,000ppm | Parent brushes |
| 3–6 years | Pea-sized | 1,350–1,500ppm | Parent leads, child helps |
| 7+ years | Pea-sized | 1,350–1,500ppm | Child brushes, supervised |

Making brushing a habit children enjoy
The mechanics are easy; the motivation is the hard part. A few tricks reliably help:
- Brush together. Children copy what they see, so let them watch you brush and make it a shared routine rather than a solo task.
- Use a two-minute timer. A sand timer, a favourite song, or a brushing app turns the clock into a game.
- Give them some control. Letting your child choose their own brush colour or character toothpaste boosts buy-in enormously.
- Use a reward chart. A sticker for every morning and night, with a small treat at the end of the week, works wonders for under-eights.
- Tell the story of the "sugar bugs". Framing plaque as bugs to brush away makes the job feel purposeful and fun.
Electric or manual?
Either works well when used properly. Many children find a small electric brush easier to use and more engaging, and the built-in timers help with the two-minute target. A manual brush with a small head and soft bristles is perfectly effective too, consistency matters far more than the type of brush.
Wimbledon has hard water, but it isn't fluoridated. South-west London's tap water is hard, which is great for limescale-fighting kettle adverts but offers no real protection against tooth decay, as our area is not part of an artificial water-fluoridation scheme. That makes the fluoride in your child's toothpaste their main daily defence. With the Common nearby for weekend sport and plenty of post-match treats around the Village, a solid twice-a-day brushing routine is worth its weight in gold for SW19 kids.

Almost every parent hits a few hurdles. Here is how we suggest handling the most common ones:
- The refusenik toddler. Try brushing while they lie back on your lap so you can see clearly, sing a short song, and keep it brief but consistent. A struggle that lasts 30 seconds is still better than skipping it.
- The "I already did it" fibber. Older children sometimes wet the brush and claim victory. A disclosing tablet, which stains plaque a bright colour, turns missed spots into an honest game.
- The bedtime rush. Brush before the bedtime story rather than after, so teeth-cleaning doesn't become the last hurdle before sleep when everyone is tired and tetchy.
- Bleeding gums. A little bleeding usually means gums need more gentle brushing, not less, but mention it at your next visit so we can check.
When to involve your dentist
Brushing at home and professional care go hand in hand. NHS dental care is free for children under 18 in England, and most children should be seen every 6 to 12 months depending on their individual risk of decay. Regular visits let us spot early decay, apply protective fluoride varnish, and keep coaching your child's technique as they grow. As they get older, a hygienist visit adds another layer of protection and reinforces the habits you have built at home.

Frequently asked questions
Children can start having a go from a young age, but the NHS advises that you supervise brushing until your child is at least seven. Until then their coordination isn't reliable enough to clean every surface properly, so it helps to brush for them or finish off after their turn.
The NHS recommends a smear of fluoride toothpaste (at least 1,000ppm fluoride) for children under three, and a pea-sized amount of toothpaste containing 1,350–1,500ppm fluoride from age three upwards. Encourage your child to spit out but not rinse, so the fluoride keeps working.
South-west London has hard water, but tap water here is not artificially fluoridated, so it doesn't add meaningful protection against decay. That makes brushing twice a day with the right amount of fluoride toothpaste even more important for Wimbledon children.
