When to take your baby to the dentist

Ask three people when a child should first see a dentist and you might hear three answers: age one, age two, or "wait until there's a problem." Even some dental offices still say two or three.

The answer is six months after their first tooth

Take your child for a first dental visit within six months of the first tooth coming in, or by their first birthday — whichever comes first. This isn't one group's preference. As the American Academy of Pediatrics states it, "The AAP, the American Academy of Pediatric Dentistry, the American Dental Association, American Dental Hygienists' Association, and the American Association of Public Health Dentistry all recommend a dental visit for children by 1 year of age."¹² An office still telling parents to wait until two or three is working from older advice.

Why so early — and why it changed

For most of the last century, that first visit happened around age three. The recommendation moved earlier when dentistry's understanding of cavities changed. As one clinical history puts it, "Once dental caries was understood as a chronic bacterial disease with a behavioral component, the paradigm shifted from treating the resulting damage to addressing the cause (prevention)."³ Decay can begin the moment the first teeth appear, so waiting until three meant waiting too long to prevent it. The shift had momentum behind it: the year 2000 U.S. Surgeon General's report had just called tooth decay "the single most common chronic childhood disease."⁴ In 2001 the pediatric dentists built the new thinking into a "dental home" policy — the idea that a child should have a steady dental relationship by age one, the way they already have a pediatrician.

How strong is the evidence?

Experts agree on the age-one timing, but the trial evidence behind it is thin. A University of North Carolina review of the research behind it was blunt: "the currently available evidence base supporting the effectiveness of EPDVs and the year 1 first dental visit recommendation is weak."⁵ (EPDV is shorthand for an early preventive dental visit.) The studies that support it are mostly older insurance records showing lower dental costs later, not the controlled trials that would prove cause. The U.S. Preventive Services Task Force, which grades this kind of evidence, found "the current evidence is insufficient" to judge routine dental screening for children under five one way or the other, while finding that fluoride varnish helps.⁶ The clearest benefit shows up in children at higher risk of decay.

None of that is a reason to wait. An early visit gets your child used to the chair before anything is wrong, and it costs little. That, plus catching trouble early in the children most likely to have it, is why to go — even if the exact timing isn't settled science.

"They fall out anyway"

The other common doubt is whether baby teeth are worth the trouble, since they fall out. They are. Baby teeth hold the space for the adult teeth and guide them in: "Missing baby teeth leave gaps, causing nearby teeth to shift around. This can keep your child's permanent teeth from coming in correctly."⁷ They also let a child chew and speak clearly, and a decayed baby tooth can hurt enough to need pulling. Decay this early is common: about 11% of children aged two to five already have an untreated cavity.⁸

The simple version: book that first visit about six months after the first tooth. It's mostly a look and a few questions about brushing and bottles, and the habit it builds outlasts the appointment. We're glad to be that first visit.
