When Should a Child First See an Orthodontist?

Why orthodontists recommend a first check-up by age 7, what happens at that visit, and what early Phase I treatment is and is not meant to do.

The short answer: by age 7

The American Association of Orthodontists (AAO) recommends that children have their first orthodontic check-up no later than age 7. That surprises many parents, because most kids who need braces do not get them until their pre-teen or teen years. The point of an early visit is not to start treatment right away. It is to have a specialist look at how the teeth and jaws are developing while there is still time to guide that growth if it is needed.

Why age 7?

Around this age most children have a mix of baby teeth and permanent teeth. The first permanent molars have usually come in, which establishes the back bite, and the front permanent teeth are arriving. That mix gives an orthodontist enough information to spot developing problems, such as:

• Crowding, where there may not be enough room for the permanent teeth that are still coming.
• Crossbites, where upper teeth sit inside or behind the lower teeth, which can affect how the jaw grows.
• Narrow upper jaws, which in younger children can sometimes be widened with a palatal expander because the jaw is still growing.
• Teeth that are likely to become impacted, meaning they may get stuck and not erupt properly.
• Habits like prolonged thumb or finger sucking that can change how teeth and jaws develop. The AAO has a parent guide on pacifiers and thumb sucking.

Your family dentist may also notice these issues at a routine cleaning and suggest a visit. If you have concerns of your own, such as teeth that do not meet when your child bites down, a jaw that shifts to one side, or front teeth that stick out noticeably, it is reasonable to ask for an evaluation sooner.

Before the first visit

• Ask your family dentist to send recent X-rays. HIPAA lets one provider share records with another for treatment without a separate authorization (45 CFR 164.506), so a call from either office is usually enough. The orthodontist decides whether those images are enough or new ones are needed.
• Write down what you have noticed, such as teeth that do not meet, a jaw that shifts, or a thumb habit, and roughly when it started.
• Ask about cost when you book. Find out whether the evaluation, X-rays or photos are billed, and whether your dental plan covers them. The guide to paying for orthodontic treatment covers insurance, Medicaid and payment plans.
• Check the provider. The orthodontist or general dentist guide shows how to look up an NPI record, a state dental license and board certification.

What usually happens at the first visit

An orthodontic check-up for a young child is typically a look at the teeth, bite and jaw, sometimes with X-rays or photos. The AAO notes that "not all early visits result in orthodontic treatment." In general, there are three possible outcomes:

• No treatment needed right now, with development looking on track.
• Monitoring, where the orthodontist wants to see your child periodically as teeth come in and the jaws grow, and decide later whether treatment makes sense.
• Early (interceptive) treatment, recommended because a specific problem is easier to correct while the child is still growing.

Many orthodontists offer the initial evaluation as a consultation, but policies vary, so ask about any charges when you book.

What early (Phase I) treatment is

When early treatment is recommended, it is often called Phase I of a two-phase approach. According to the AAO's overview of two-phase treatment, Phase One usually starts while a child still has some baby teeth and is aimed at jaw development differences, bite problems, severe crowding or eruption issues. The AAO puts it this way: "In Phase One, the goal is not perfection; it is to set the stage for healthier development."

Phase I might involve a palatal expander, a limited set of braces on some teeth, a space maintainer, or an appliance to help with a habit. It is usually shorter than full treatment. It is typically followed by a resting period while the rest of the permanent teeth come in, and then, if needed, Phase II: comprehensive braces or aligners to fine-tune the position of all the permanent teeth.

What early treatment is not

Early treatment is not a way to get braces "over with" sooner, and it is not needed for every child. The AAO states plainly that two-phase treatment "is not required for all kids" and that "for many children, a single phase of comprehensive orthodontic treatment is still the right path." Many common issues, such as mild crowding, are routinely treated later in a single phase once the permanent teeth are in.

Early treatment also does not always eliminate later treatment. A child who has Phase I care may still need braces or aligners as a teenager, although the second phase may be simpler as a result. If an orthodontist recommends early treatment, it is fair to ask:

• What specific problem are we treating now, and what happens if we wait?
• Is this problem easier to fix while my child is still growing?
• Will my child likely still need a second phase later, and is that included in the fee?
• How long will this phase last, and how often are appointments?

A clear explanation of why timing matters for your child's particular problem is a good sign. If the answer is vague, a second opinion from another orthodontist is a normal and reasonable step.

If your child has Medicaid or CHIP

Children under 21 enrolled in Medicaid are covered by the EPSDT benefit. Medicaid.gov says every child must be referred to a dentist on a schedule the state sets after consulting dental organizations, and that covered dental services must include medically necessary orthodontic services. States decide what counts as medically necessary, so a recommendation for early treatment does not by itself mean Medicaid will pay for it.

Separate CHIP programs choose their dental package within federal rules, so orthodontic coverage differs by state. InsureKidsNow.gov has a dentist locator for providers who see children and accept Medicaid and CHIP. Before the visit, ask the office whether it takes your child's plan and whether any treatment would need prior approval.

Teens and adults are not too late

Missing the age-7 check-up does not rule anything out. Most comprehensive orthodontic treatment happens in the pre-teen and teen years, and the ADA's MouthHealthy notes that many adults also seek treatment. Some jaw-growth problems are easier to address in childhood, so an early look is useful, but teeth can be moved at any age as long as the gums and bone supporting them are healthy.
