Children's Oral Health

How can I care for my child's teeth?

A regular teeth-cleaning routine is essential for good dental health. Follow these tips and you can help keep your children's teeth pearly white and free from cavities.

In Short
Fizzy drinks, sweets and fruit juice all can cause tooth decay and enamel erosion.

If they do have sweets and fruit juice occasionally as a treat - give them straight after a meal - then wait half an hour before brushing their teeth.

The last thing on your child's teeth before bedtime should be fluoride toothpaste.

Ages 0 - 3 - use a smear of toothpaste containing more than 1000ppm fluoride.

Ages 3-6 – use a pea sized amount of toothpaste containing more than 1000ppm fluoride.

Age 7+ - use a pea sized amount of toothpaste containing between 1350-1500ppm fluoride.

At least 2 minutes twice a day - use an eggtimer or a free app to make it more fun.

Until your child is at least 7, you can brush their teeth for them - or at least supervise the brushing. It's better for them to have properly brushed teeth than insist on them doing this on their own.

You can start teaching your child to brush their teeth by guiding the brush with your hand and showing them the movements.

Until their 18th birthday, dental appointments should never be more than 12 months apart. Your dentist may advise more regular appointments.

Toothbrushing tips

Brush your child’s teeth for about two minutes twice a day: once just before bedtime and once in the morning.

The last thing on your child’s teeth at bedtime should be fluoride toothpaste.

Don’t brush straight after sugary treats – including drinks such as fizzy drinks or fruit juice. This is because sugar softens the enamel – so if you brush straight away, you can erode it away. Wait half an hour and then brush.

Encourage them to spit out excess toothpaste, but not to rinse with lots of water. Rinsing with water after tooth brushing will wash away the fluoride and make it less effective.

Supervise tooth brushing – or do it yourself – until your child is at least seven years old, even older if necessary.

Make tooth brushing as fun as possible by using an egg timer to time it for about two minutes – or find a fun app, like BrushDJ.

Saliva plays a vital role in keeping teeth protected from plaque acid as it has a pH of 7.1. Saliva production is reduced at night-time so avoid food and sugary drinks before bedtime.

Change the brush regularly – especially when the bristles start to curve or look worn out.

Don’t let children run around with a toothbrush in their mouth, as they may have an accident and hurt themselves.

Toothpaste & fluoride
  • Ages 0 – 3 – use a smear of toothpaste containing more than 1000ppm fluoride.
  • Ages 3 – 6 – use a pea sized amount of toothpaste containing more than 1000ppm fluoride.
  • Age 7+ use a pea sized amount of toothpaste containing between 1350-1500ppm fluoride.

Make sure children don’t eat or lick toothpaste from the tube.



Taking your child to the dentist – Fluoride varnish and fissure sealants

In the UK, you can register for free with an NHS dentist. He or she will recommend appointment intervals. Dental care is free for children up to the age of 18 (or up to 19 if in full-time education).

Every child should have fluoride varnish painted on their teeth twice a year from the age of two or 4 times a year if they are at high risk of dental decay. Once permanent molars come through, from the age of about 6 or 7, fissure sealants can be placed on chewing surfaces to help protect them from decay. Sealants should be applied as soon as the molar teeth come through if the child has had decay in their first teeth. If there is decay in a permanent molar, then fissure sealants should be placed on all other permanent molar teeth.

My child doesn’t like cleaning his teeth – what can I do?

It’s important for your child to be independent, but if they’re not cleaning their teeth properly, you’ll need to step in. You can teach them independence with other activities.

Note from Essential Parent Co-Founder, Diana Hill – “My dentist cleaned her own children’s teeth until they were 10. She felt it was more important for them to have clean teeth, and avoid cavities, than worrying about whether they were cleaning them independently.”

If your child is resistant to you cleaning his teeth you could negotiate a situation where they are allowed to do the first clean (or the last clean) and you get to clean as well for around 2 minutes.

Be really gentle as it can be very uncomfortable and painful having someone else clean your teeth.

You can use toothbrushes that light up for 2 minutes, or a fun app like BrushDJ, or an egg timer to help your child to see how long to clean his teeth. These tricks help the time go by and side-tracks a reluctant tooth brusher.
