When Should Children First See a Dentist?

Professional guidance points at the first birthday, or within six months of the first tooth appearing, whichever comes first. That routinely surprises parents, who often assume three or four is early enough.

Why so early?

Two reasons, and neither is about drilling. The first is that decay can affect baby teeth remarkably early, particularly with prolonged bottle use at night. The second is that a first visit at one year old is an easy, uneventful experience — which is exactly the point.

A child whose first dental memory is a friendly appointment where nothing happened has a very different relationship with dentistry than one whose first visit came at five because something hurt.

What a first visit actually involves

• A quick, gentle look at the teeth and gums, often with the child on a parent's lap
• A check that teeth are coming in as expected
• Practical guidance on brushing a small child's teeth, which is genuinely awkward until someone shows you
• A conversation about bottles, cups, and night-time feeding
• Advice on thumb sucking and dummies where relevant
• Time for your questions, which is most of the value for many parents

Why baby teeth matter

The most persistent myth in children's dentistry is that baby teeth do not matter because they fall out. They hold space for the adult teeth developing underneath and guide them into position. A baby tooth lost early to decay can let neighbouring teeth drift into the gap, which affects how the adult tooth comes through.

Decay in baby teeth also causes real pain and can lead to infection. Losing a tooth eventually is not the same as it not mattering now.

Practical things that reduce risk

• Do not put a child to bed with a bottle of anything except water
• Start cleaning as soon as the first tooth appears, with a soft brush and a smear of fluoride toothpaste
• Brush for them, or at least after them, until they have the coordination to do it properly — usually well into primary school
• Move to a cup rather than a bottle around the first birthday
• Keep juice to mealtimes rather than sipping through the day

Our guide to helping children feel comfortable at the dentist covers preparation and language that works, and it is worth reading before a first visit.
