When Should Kids Start Going to the Dentist?

Almost every parent I meet is late to this, and nobody should feel bad about it, because the recommendation is genuinely counterintuitive.

Age one sounds absurd for a dental appointment. There are barely any teeth. Nothing needs treating. What could possibly be the point.

The point is that the first visit is not about the teeth.

Why age one, when there is nothing to treat

Three reasons, and none of them involve doing anything to your child.

First, cavities in baby teeth are common and they start earlier than people think. Decay in a two year old is not rare, and the highest risk period begins as soon as teeth are in the mouth and being exposed to sugars, including milk and juice at night.

Second, the visit is mostly for you. What to do about bottles at bedtime, whether that thumb habit matters yet, how much toothpaste to use, whether the water in your area is fluoridated, what to do when a toddler will not open their mouth. That is a genuinely useful twenty minutes and it happens before there is a problem to fix.

Third, and this is the one that pays off for a decade, it establishes that the dental office is a normal place. A child who has visited three times before anything is ever done to them has a completely different relationship with the chair than a child whose first visit is at four years old because something hurts.

The American Academy of Pediatric Dentistry and the ADA both put the first visit at age one or within six months of the first tooth.

What the first visit actually looks like

Short, and often on your lap.

For a one or two year old, the most common approach is a knee to knee examination, where the child sits facing you on your lap and lies back with their head in the dentist lap. It takes a couple of minutes, they can see you the entire time, and it works far better than trying to get a toddler to sit alone in a large chair.

A quick look for early decay, a check on how the teeth and jaws are developing, sometimes a fluoride varnish painted on, which takes about a minute.

Then the conversation with you, which is most of the appointment.

Nobody is going to force anything. If a child is having a bad day, the visit becomes even shorter and we try again in six months. Building tolerance across several visits is the strategy, not winning the first one.

What to expect at each age

Roughly what matters when.

Tap and drag the table sideways to see every column.

They are just baby teeth, though

This is the objection, and it is worth answering properly rather than dismissing.

Baby teeth hold space for the permanent teeth coming in behind them. Lose one early to decay and the neighbouring teeth drift into the gap, which means the permanent tooth has nowhere to go. That is a straightforward path to crowding that could have been avoided, and it is one of the more common reasons a nine year old ends up needing orthodontic treatment they would not otherwise have needed.

They also matter right now. A decayed baby tooth hurts, gets infected, and affects eating, sleeping, and school in exactly the way an adult toothache would.

And the back baby teeth are not shed until around ten to twelve years old. A cavity at three in a tooth that is staying for another nine years is not a temporary problem.

The two things that prevent the most cavities

Beyond brushing, which everyone knows about.

What happens at night. Milk, juice, or anything sweet in a bottle at bedtime pools around the front teeth for hours while saliva flow drops. This single habit accounts for a substantial share of early childhood decay, and it is the one worth changing first. Water only after teeth are brushed.

Sealants on the six year molars, as soon as they are fully erupted. The chewing surface of those teeth has deep narrow grooves that a toothbrush bristle physically cannot enter, and that is where most childhood cavities start. Sealing them takes minutes, requires no numbing, and it is the highest return preventive thing available for a school age child.

Fluoride varnish at each visit is the third, and it is two minutes.

If you are already past age one

Which is most people, so this is not a reprimand.

Just book. There is no penalty and nobody is going to comment on the timing. What matters is starting.

If your child is older and nervous, say so when you book so the appointment is scheduled with enough time. A first visit that is unhurried is worth two rushed ones. Nitrous oxide is available for genuinely anxious kids and is a much lighter option than people assume, which we covered in the piece on laughing gas.

And if cost is the reason it has been delayed: dental coverage for children in Texas is far better than for adults. Medicaid and CHIP cover comprehensive dental care for anyone under 21, and we see those patients. Details are in how Medicaid and CHIP work here.

Common questions

When should my child first see a dentist?

By their first birthday, or within six months of the first tooth erupting. Both the ADA and the American Academy of Pediatric Dentistry recommend this.

What happens at a one year old dental visit?

A short examination, often with the child on your lap, a check for early decay and development, usually a fluoride varnish, and a conversation with you about bottles, brushing, and habits.

Do baby teeth really matter if they fall out anyway?

Yes. They hold space for the permanent teeth, and losing one early lets neighbouring teeth drift into the gap, which causes crowding. The back baby teeth are not shed until around age ten to twelve.

How much toothpaste should a young child use?

A smear the size of a grain of rice under age three, and a pea from three to six, with an adult supervising and teaching them to spit.

When should my child first see an orthodontist?

Around age seven, and usually not to begin treatment. It is an assessment of how the adult teeth and jaws are developing while there is growth left to work with.

My child is anxious about the dentist. What can we do?

Say so when you book so extra time is scheduled. Building tolerance across several short visits works better than one long one, and nitrous oxide is available for children who need it.
