Simple prevention at home

This area offers practical preventive oral-health education for parents, carers and families. It focuses on everyday routines, explains why they matter and helps families know when to contact a dental professional.

Brushing and fluoride

A regular routine and the right amount of fluoride toothpaste help protect children's teeth.

  • Brush twice each day for about 2 minutes: last thing before bed and on one other occasion.
  • For children up to age 3, use a smear of toothpaste with at least 1,000ppm fluoride. For ages 3 to 6, use a pea-sized amount with 1,000 to 1,500ppm fluoride. From age 7, use 1,350 to 1,500ppm fluoride.
  • A parent or carer should brush younger children's teeth and help or supervise until the child can brush every surface well. Many children still benefit from supervision after age 7.
  • Encourage children to spit out after brushing rather than rinse with water, so the fluoride is not washed away.

Food, drinks and tooth decay

Small, realistic changes to when sugary foods and drinks are offered can reduce how often teeth face an acid challenge.

  • Bacteria in dental plaque can turn sugars from food and drink into acid. Frequent sugary snacks or drinks mean repeated acid challenges for teeth.
  • Keep sugary foods and drinks to mealtimes where possible instead of offering them frequently between meals.
  • Make water the usual drink between meals and throughout the day.
  • There is no need for an all-or-nothing change. One achievable swap or a less frequent sugary snack is a useful place to start.

When professional advice is needed

A dental professional can examine a child's mouth and decide what care, if any, is needed.

  • Contact a dentist if a child has dental or mouth pain, swelling, a dental injury, symptoms that persist, or anything else about their teeth, gums or mouth that concerns you.
  • For an urgent dental problem, contact a dentist or use NHS 111 for advice. Follow NHS emergency guidance for serious facial or jaw injuries, uncontrolled heavy bleeding, or severe swelling that affects breathing.
  • This page does not assess symptoms, diagnose a condition, provide individual treatment instructions or create a risk score.

Frequently asked questions

Brief answers to common questions about children's everyday oral health.

How often should children brush their teeth?

Children should brush twice a day for about 2 minutes: last thing before bed and on one other occasion.

Sources: OH-UK-001, OH-UK-002

Why is brushing before bed important?

Bedtime brushing removes plaque and leaves fluoride on the teeth during the night, when saliva flow is lower.

Sources: OH-UK-001, OH-UK-002

What does fluoride toothpaste do?

Fluoride helps prevent and control tooth decay by making tooth enamel more resistant to acid damage.

Sources: OH-UK-001, OH-UK-002

Should children rinse after brushing?

No. Encourage them to spit out the excess toothpaste without rinsing with water, so fluoride stays on the teeth for longer.

Sources: OH-UK-001, OH-UK-002

Why does the frequency of sugary snacks and drinks matter?

Each sugary snack or drink can lead to an acid challenge. Having them often gives teeth less time to recover, so keeping them to mealtimes where possible can help.

Sources: OH-UK-002, OH-UK-004

At what age should a parent help with brushing?

Parents or carers should brush young children's teeth and help as they learn. Many children can brush independently from around age 7, but they may still need watching or help to clean every surface well.

Sources: OH-UK-001, OH-UK-002

What should I do if I am worried about my child's teeth or mouth?

Contact a dentist for an examination and advice. For pain, swelling, injury or another urgent concern, contact a dentist or use NHS 111 to find the right service.
