Most kids get braces between ages 10 and 14, when nearly all their permanent teeth have come in. But the process starts earlier than most parents expect. The American Association of Orthodontists recommends every child have their first orthodontic evaluation by age 7, even if their teeth look fine. That screening helps catch problems that are easier to fix while a child is still growing.
Why Age 7 for the First Visit
Seven might sound early for thinking about braces, but it’s not about putting brackets on a second grader. By age 7, most children have a mix of baby teeth and permanent teeth, and an orthodontist can spot developing problems in jaw growth, bite alignment, and spacing that aren’t obvious to parents. The goal is to identify issues early, not necessarily to treat them right away.
Many kids who get evaluated at 7 won’t need any immediate treatment. The orthodontist may simply monitor their development over the next few years and recommend braces later when the timing is right. But for some children, catching a problem early can prevent more invasive treatment, including surgery, in adulthood. If you notice something that looks off before your child turns 7, there’s no reason to wait for that birthday. You can bring them in at any age.
Early Treatment: Ages 6 to 9
A smaller group of kids benefit from what’s called Phase 1 treatment, which typically happens between ages 6 and 9. This isn’t full braces. It’s a targeted intervention lasting about 9 to 12 months that addresses a specific structural problem while the jaw is still growing and more responsive to correction.
Common Phase 1 treatments include palatal expanders, which widen a narrow upper jaw to reduce crowding, and space maintainers, which hold open gaps left by lost baby teeth so permanent teeth have room to come in straight. Sometimes a short course of partial braces corrects an issue like a front crossbite (where upper teeth sit behind the lower ones). In some cases, removing a baby tooth or an impacted tooth can guide permanent teeth into better positions without any appliance at all.
The problems that benefit most from early intervention include underbites, crossbites, significant crowding, excessive spacing, extra or missing teeth, teeth that don’t meet properly when biting down, and thumb or pacifier habits that have affected jaw growth. Left untreated during childhood, some of these issues become harder and more expensive to fix once the jaw stops growing.
The Most Common Age for Full Braces
The majority of kids start comprehensive orthodontic treatment, meaning full upper and lower braces or clear aligners, between ages 10 and 14. This is the sweet spot for several reasons. Most or all permanent teeth have erupted by this age, giving the orthodontist a complete picture to work with. The jaw is still growing, which makes it easier to guide teeth into alignment. And treatment during adolescence tends to move a bit faster than in adulthood because the bone surrounding the teeth is less dense.
Full treatment typically lasts 18 to 24 months, though complex cases can take longer. Kids who had Phase 1 treatment earlier may have a shorter Phase 2 round of braces during adolescence, since some of the groundwork was already laid. Others skip early treatment entirely and do everything in one phase during their teen years.
Does Age Affect How Well Treatment Works?
Braces work at any age, but younger patients and older patients bring different strengths to the process. Adolescents have the biological advantage of active growth, which helps teeth move efficiently. Adults, on the other hand, tend to be more cooperative. Research comparing the two groups found that adolescents had roughly double the rate of broken brackets (25.4%) compared to adults (12.3%), largely because adults who chose treatment themselves were more motivated to follow care instructions.
For kids and teens, compliance matters more than most parents realize. Wearing rubber bands as directed, avoiding hard and sticky foods, and keeping teeth clean around brackets all influence how smoothly treatment goes and whether it finishes on schedule. Kids who are old enough to understand and care about the outcome tend to do better than those who feel like braces were imposed on them.
Signs Your Child May Need Braces
Some indicators are visible at home well before an orthodontist weighs in. Watch for teeth that are visibly crooked or overlapping, a noticeable gap between the upper and lower front teeth when the mouth is closed, difficulty chewing or biting, mouth breathing, or jaws that click or shift to one side. If your child lost baby teeth very early or very late compared to peers, that can also signal spacing or alignment issues worth checking.
Keep in mind that crooked baby teeth don’t necessarily predict crooked permanent teeth, and straight baby teeth don’t guarantee the permanent ones will come in aligned. The underlying jaw structure matters as much as the teeth themselves, which is why that age 7 screening catches things that a mirror at home can’t.
