A first orthodontic check at about seven does not mean braces at seven. The American Association of Orthodontists suggests a check by that age because most children then have a mix of baby and adult teeth, which is enough to judge how the jaws and teeth are developing. For most children the result is a plan to keep watching. For a smaller group, there is a specific problem that is easier to correct while they are still growing.
What can be judged at seven
With a few permanent teeth through, a dentist or orthodontist can see how the upper and lower jaws line up front to back and side to side, whether there is likely to be enough room for the adult teeth still to come, and whether a habit is starting to affect the shape of the mouth. X-rays can show missing or extra teeth and adult teeth heading in the wrong direction. Many of these checks happen as part of routine visits, and a dentist or OHT can refer to a registered orthodontist when something needs a closer look.
Problems where acting early can help
Crossbites. When upper back teeth bite inside the lower ones, a child may slide the jaw to one side to close, and over time growth can follow that shift. Widening the upper jaw with an expander is often more straightforward in younger children, because the midline joint in the palate tends to respond more readily before it matures. That maturation varies widely between individuals, as research by Angelieri and colleagues in 2013 showed, so age alone does not decide it. In older teens and adults, conventional expanders become less effective, and options such as miniscrew assisted expansion (MARPE) or surgically assisted expansion may be considered; see adult palatal expansion with MARPE. Our guide to palatal expanders explains how they work in children.
Prominent upper front teeth. Teeth that stick out are more likely to be chipped or knocked out in a fall. A Cochrane review by Batista and colleagues in 2018 found that early treatment for prominent upper teeth reduced the chance of front tooth injury, though it offered little other advantage over starting treatment in early adolescence.
Baby teeth lost too early. If a back baby tooth is lost to decay or injury long before its adult replacement is due, neighbouring teeth can drift into the gap. A space maintainer can hold it open; see our article on space maintainers.
Habits that persist. Thumb or finger sucking continued after the adult front teeth arrive can push them forward and narrow the upper jaw. Helping a child stop is usually the first step.
Other bite patterns, including underbites, are discussed in our guide to overbite, underbite and crossbite.
Many things that worry parents are normal
Gappy, slightly crooked or oversized looking front teeth at seven or eight are often part of a normal phase that improves as the canines come through, sometimes called the ugly duckling stage. Mild crowding of the lower front teeth is also common at this age and may ease. Knowing what is expected spares a lot of worry, and our article on when baby teeth fall out gives the usual order.
Why waiting is often the right call
Starting full braces before most adult teeth are through usually means wearing appliances for longer overall, often without a better final result. Unless there is a clear reason to act, many orthodontists prefer to wait until the early teens, when most adult teeth have erupted and treatment can be done in one stretch. Being told your child does not need anything yet is a good outcome, as long as you know what is being watched and when to come back.
How two phase treatment works
When early treatment is advised, it is usually aimed at one problem: widening a narrow upper jaw, holding space or reducing very prominent teeth. That first phase is followed by a rest period while the remaining adult teeth come through. A second phase in the teens, with braces or aligners, then aligns the full set if needed. Some children need only the first phase, many need only the second, and the plan should be explained with that in mind.
Costs and cover
Assessment fees and treatment costs vary with what is needed, so the only reliable figure is a written treatment plan with fees after your child is examined. The Child Dental Benefits Schedule covers check ups and many basic services for eligible children, but it does not cover orthodontic treatment. Private health extras may include an orthodontic benefit, usually with waiting periods and a lifetime limit. Current consultation options are on our deals page.
Questions parents ask
My child is ten and has never had an orthodontic check. Is it too late?
No. Some problems are easier to address earlier, but an assessment at any age will show what can be done now.
Will early treatment mean no braces later?
Sometimes, not always. Early treatment targets a specific problem. Many children still have a shorter course of braces or aligners as teenagers.
Can our regular dentist do the check?
Yes. Routine check ups include looking at how the teeth and bite are developing, with referral to a registered orthodontist when needed.
If you are unsure if your child needs an early look, the team at Lumi Dental can check their teeth and bite and explain whether to treat, refer or simply watch. Our guide to your child's first dental visit covers what to expect. See current options or contact us to book.
