NHS Dentistry for Children: A Parent's Guide

Author : George Brown | Published On : 06 Nov 2026

Parents have plenty to think about, and dental care can slip down the list until a child complains of toothache. Yet tooth decay is one of the most common childhood health problems, and it is almost entirely preventable.

The good news is that NHS dental care is free for children in England. This guide explains when to start, what to expect at visits, and simple habits that protect little teeth.

Is NHS Dental Care Free for Children?

Yes. NHS dental treatment is free for everyone under 18, and for 18-year-olds in full-time education. That covers check-ups, fillings, extractions, and other clinically necessary care. There is no charge for urgent treatment either.

Because cost is not a barrier, there is every reason to book regular check-ups early.

When Should My Child First See a Dentist?

The NHS advises taking your baby to the dentist as soon as their first teeth appear, rather than waiting until they are older. Early visits are usually short and low-pressure. The dentist checks how the teeth are coming through, talks to you about cleaning and feeding, and helps your child get used to the setting.

Many parents find it helpful to bring their baby along to their own check-up first, so the dental chair becomes familiar.

What Happens at a Child's Check-Up?

Expect the visit to be simple and friendly:

• The dentist looks at your child's teeth, gums, and mouth.
• They check for early signs of decay and how the teeth are developing.
• They may apply fluoride varnish to strengthen the enamel, usually from around age three.
• They may recommend fissure sealants, a protective coating on the chewing surfaces of back adult teeth, once those teeth appear.
• They talk about brushing, diet, dummies, thumb-sucking, and anything else on your mind.

X-rays are only taken when there is a clear reason.

How Often Should Children Go?

The dentist will decide based on your child's risk of problems. Children are often seen every 6 to 12 months, and more often if they are prone to decay. Ask at the end of each visit when to return.

Everyday Habits That Protect Children's Teeth

Brushing

• Start brushing as soon as the first tooth appears.
• Brush twice a day, including last thing at night.
• For children under three, use a smear of toothpaste containing at least 1,000 ppm fluoride.
• From age three to six, use a pea-sized amount of toothpaste with 1,350 to 1,500 ppm fluoride.
• Help or supervise until at least age seven, because young children cannot brush thoroughly alone.
• Encourage them to spit out toothpaste rather than rinse with water.

Food and Drink

• Keep sugary foods and drinks to mealtimes, rather than snacking throughout the day.
• Offer water and plain milk as the main drinks between meals.
• Avoid putting juice, squash, or fizzy drinks in a baby's bottle.
• Move from bottle to free-flow cup from around six months, aiming to stop bottles by about 12 months.
• Check labels, as "no added sugar" drinks can still be acidic.

Dummies and Thumb-Sucking

These are normal for babies and toddlers, but prolonged use can affect how teeth line up. Gently encouraging children to stop, ideally by age three to four, helps. Never dip a dummy in sugar or honey.

Helping a Nervous Child

Many children are fine at the dentist, but some feel anxious. A few things can help:

1. Talk about the visit in a positive, matter-of-fact way.
2. Avoid words such as "hurt," "needle," or "drill."
3. Read a children's story or play pretend dentist at home.
4. Choose a time when your child is rested and not hungry.
5. Stay calm yourself, because children pick up on our feelings.

If a child needs treatment, tell them honestly and simply what will happen. A caring team will explain steps in child-friendly language.

What About Braces?

NHS orthodontic treatment is available to some children and young people, but only when it is clinically needed. Dentists assess how severe the problem is, and there can be waiting lists. If you are concerned about your child's bite, ask the dentist early.

Signs Your Child Needs to See a Dentist Sooner

• Toothache or sensitivity
• Brown or black spots on teeth
• Swollen or bleeding gums
• Facial swelling
• A knocked or broken tooth
• Bad breath that does not go away

For emergencies, call your dentist or NHS 111. Go to A&E for swelling that affects breathing or swallowing, or a serious injury.

Finding a Practice That Welcomes Families

Look for a practice that sees children, offers convenient appointment times, and has a team who are friendly and patient. Practices offering NHS dentistry in London often welcome families and can explain what is covered for your child.

The Bottom Line

NHS dental care for children is free, and a few simple habits go a long way: a first visit when teeth appear, twice-daily brushing with fluoride toothpaste, fewer sugary drinks and snacks, and regular check-ups. Starting early helps children grow up with healthy teeth and without fear of the dentist.
