What Age Should a Child Start Seeing a Dentist?

A clear guide for parents in the UK

One of the most common questions parents ask is:
When should my child first see a dentist?

The simple answer in the UK is:
Children should see a dentist by their first birthday, or within six months of their first tooth appearing — whichever comes first.

Why so early?

Many parents are surprised by this advice. After all, babies may only have one or two small teeth. However, early dental visits are not just about checking teeth — they are about prevention, guidance and building confidence.

Early appointments allow the dentist to:

• Check that teeth are developing normally
• Spot early signs of decay
• Give advice on brushing and fluoride toothpaste
• Discuss dummy use, bottle feeding and diet
• Help your child become comfortable in a dental setting

What happens at the first appointment?

The first visit is usually short and gentle. It may include:

• A quick look at the teeth and gums
• Advice for parents about brushing techniques
• Guidance on the correct strength of fluoride toothpaste
• Discussion about sugar intake and drinks

There is rarely any treatment at this stage. The main goal is to make the experience positive and relaxed.

Is it free in the UK?

Yes. NHS dental care is free for children under 18 (or under 19 in full-time education). That includes routine check-ups from infancy.

Why not wait until they are older?

Tooth decay can develop soon after baby teeth appear. In the UK, tooth decay remains one of the most common reasons children are admitted to hospital for dental extractions under general anaesthetic.

Early visits significantly reduce this risk because problems can be spotted and prevented before they become severe.

How often should children see a dentist?

After the first visit, most children are seen every six months. However, the dentist may recommend shorter or longer intervals depending on:

• Risk of tooth decay
• Diet and sugar intake
• Oral hygiene habits
• Medical history

Tips for a successful first visit

• Choose a morning appointment when your child is well-rested.
• Keep explanations simple and positive.
• Avoid using words like “pain” or “needle”.
• Read children’s books about visiting the dentist beforehand.
• Stay calm — children pick up on parental anxiety.

What if my child is already older and has never been?

It is never too late to start. Even if your child is 3, 4 or older, booking an appointment as soon as possible is the best step. Dentists are experienced in helping children feel at ease, even if it is their first visit.

Key takeaway

• First dental visit: by age 1 or within six months of the first tooth.
• NHS check-ups are free for children.
• Early visits prevent problems rather than treat them.
• Building confidence early reduces dental anxiety later in life.

Starting dental care early gives children the best chance of maintaining healthy teeth for life.
