When Should A Child First See An Orthodontist

Reviewed and updated by the Milk Orthodontics specialist team, July 2026.

The short answer: around age 7 to 8

Orthodontic associations here and overseas recommend a first orthodontic check around age 7 to 8. By then the first adult teeth are through, there is still a mix of baby and adult teeth, and the jaws are growing quickly. That mix tells a specialist a great deal about how the adult smile is shaping up.

A first check this young is not about starting treatment early. Most children we see at this age need nothing at all yet. It is about catching the small group of problems that are much easier to guide while the jaws are still growing.

Why a specialist look matters

All orthodontists are dentists first, but orthodontists then complete around three extra years of specialist university training focused only on teeth, bites and jaw growth. Your dentist watches for decay and gum health. A specialist orthodontist reads how the face and bite are developing, and some of the most important things we look for are invisible without that training, even in a child with straight looking teeth.

Signs worth an early look

• A crossbite, where the upper and lower teeth do not line up when the jaws close
• Very crowded, rotated or protruding front teeth, which are more at risk of damage
• Baby teeth lost very early or very late
• Thumb or finger sucking that continues past about age 6 or 7
• Mouth breathing, snoring or other persistent habits that shape the jaw
• A lower jaw that sits noticeably forward or back, or shifts to one side when biting

None of these mean something is definitely wrong. They simply mean it is worth having a specialist take a look sooner rather than later.

What happens at the first visit

At Milk Orthodontics the first step is a free 20 minute Smile Assessment, in the clinic or over Zoom, and you do not need a referral from your dentist. We look, we explain what we see in plain language, and we tell you honestly whether anything needs doing. Very often the answer is that everything is developing normally, and we simply keep an eye on things with a check each year, at no charge.

If early treatment is needed

When early treatment genuinely helps, it is usually gentle: plates, expanders or a short course of early braces to guide growth and make room. Where we can see from the start that a child will benefit from early treatment and full braces later, we plan and quote both phases together upfront, so there are no surprises along the way. You can read more, including honest pricing, on our children's orthodontics page.

Is my older child too late?

Not at all. The years from 11 to 15 are still the classic time for braces or aligners, because growth is on our side. If your child is already a teenager, our guide to orthodontics for teenagers covers timing, options and costs.

Already have a treatment plan from elsewhere and feel unsure? We are always happy to give a second opinion.
