Children's dental guide
5 min readFluoride toothpaste for children
Fluoride toothpaste helps protect children's teeth when used in age-appropriate amounts. A dentist may advise a different strength for individual risk.
Fluoride toothpaste is part of UK dental prevention guidance, but the amount used and toothpaste strength matter. Children should be supervised so toothpaste is used sensibly.
This guide explains general NHS advice. It does not replace a dentist's personalised recommendation for a child with higher or lower dental risk.
At a glance
Check the label
Fluoride level
- NHS guidance refers to toothpaste containing at least 1,000ppm fluoride for young children unless advised otherwise.
- Older children commonly use 1,350ppm to 1,500ppm fluoride toothpaste.
- A dentist may advise a different strength for a child's individual risk.
Use small amounts
Supervise
- Under 3s usually use a smear of toothpaste.
- Children aged 3 to 6 usually use a pea-sized amount.
- Children should spit out after brushing and should not eat toothpaste.
Ask for advice
Individual risk
- Ask a dentist if your child has decay, visible marks or repeated toothache.
- Ask for advice if a child regularly swallows toothpaste.
- Use urgent services if you think a child has swallowed a harmful amount of any product.

Fluoride supports prevention but does not remove all risk
Fluoride helps protect enamel, but decay risk also depends on diet, brushing effectiveness, dental development and individual circumstances. It does not prevent every dental problem.
Possible causes or contributing factors
- Too little fluoride exposure can reduce protection against decay.
- Too much toothpaste can increase swallowing risk in young children.
- Children with visible decay or higher risk may need personalised dental advice.
What you can do now
- Use the toothpaste amount recommended for the child's age and risk.
- Store toothpaste where young children cannot eat it from the tube.
- Supervise brushing and encourage spitting out after brushing.
What not to do
- Do not tell children to swallow toothpaste.
- Do not use more toothpaste than needed because more is not automatically better.
- Do not ignore visible decay or pain because the child uses fluoride toothpaste.
When to ask a dentist
- You are unsure which toothpaste strength to use.
- A child has toothache, visible marks or previous decay.
- A child finds toothpaste difficult because of taste, texture or sensory needs.
When prompt advice is needed
- Dental pain, swelling or trauma is present.
- A child seems unwell alongside mouth or dental symptoms.
- You are worried about possible ingestion of a dental product and need urgent advice.
What a dentist or relevant professional may assess or do
- Assess decay risk, brushing and diet factors.
- Advise on fluoride toothpaste strength and amount.
- Discuss prevention options where clinically appropriate.
Frequently asked questions
Does fluoride toothpaste stop all decay?
No. It helps protect teeth, but decay risk also depends on brushing, diet, dental development and individual risk.
Can I use adult toothpaste for my child?
NHS guidance supports family toothpaste with higher fluoride levels in some situations, but ask a dentist if you are unsure what is suitable.
What if my child swallows toothpaste?
Small accidental amounts during brushing are common. If you are worried a child has swallowed a harmful amount, contact an appropriate urgent service for advice.
