Last Update: 5/22/2026
You’ve got an 8-year-old, and the dentist just mentioned an orthodontist. Or your 11-year-old’s friends are getting braces and you’re wondering if it’s your kid’s turn. Or your 13-year-old finally lost the last baby tooth and now you’re thinking, okay, are we doing this?
If you’ve ever wanted to know exactly what happens at each age, this guide is for you.
We’ll walk through what an orthodontist looks for at every age from 7 through 14, what kinds of decisions tend to come up at each stage, and how to know if your child is on a typical timeline or somewhere off the usual path. For the broader question of what age kids get braces in general, see our general overview of orthodontic timing. This page goes age by age.
What to Watch For at Each Age (A Quick Look)
If you only have 30 seconds, here’s the whole timeline. We’ll go deeper on each age below.
| Age | What’s typically happening | Common ortho decision |
|---|---|---|
| 7 | First permanent molars and front teeth in | First evaluation (not first braces) |
| 8 | Mixed dentition phase, jaw still flexible | Monitor; flag any crossbite or severe crowding |
| 9 | More permanent teeth erupting | Phase 1 decision point if early issues are present |
| 10 | Most front teeth permanent; canines coming | Often the “pre-braces” planning year |
| 11 | Permanent teeth largely in (except second molars) | Full braces commonly start |
| 12 | Almost all permanent teeth present | Peak year for starting braces |
| 13 | Permanent teeth complete (except wisdom) | Still very common starting age |
| 14+ | Jaw growth winding down | Treatment still effective, sometimes a little longer |
That table is the cheat sheet. The next sections give you what each age actually looks like in our office.
Age 7: First Evaluation, Not First Braces
Seven is the age the American Association of Orthodontists recommends every child get a first orthodontic evaluation. It’s also the age that catches most parents off guard because it feels too early.
Here’s the thing: it’s an evaluation, not a treatment. At 7, most kids have their first permanent molars and front incisors. That mix of baby and permanent teeth is exactly what gives an orthodontist a useful read on how the bite is developing. Crowding patterns, crossbites, jaw growth issues, and missing or extra teeth all become visible at this age in ways they weren’t a year earlier.
For most 7-year-olds we evaluate, the recommendation is simple: come back in 6 to 12 months and let’s keep watching. No appliances. No braces. Just a baseline.
For a smaller group, about 1 in 5 of the kids we see at 7, there’s a specific issue that benefits from early action. Crossbites are the most common. A narrow upper jaw responds well to an expander while the bones are still flexible, and getting that done at 7 or 8 often prevents bigger problems later.
The job at age 7 is information. You leave knowing whether your child is on a standard track, needs a watchful eye, or has a specific issue worth addressing now.
Age 8: Watching for Mixed-Dentition Issues
By 8, most kids have lost their bottom front baby teeth and are working on the top ones. The mouth looks chaotic, and that’s normal. This is peak mixed-dentition phase.
What we’re watching for at this age:
How the new permanent teeth are landing. Are they coming in straight, or tipping in a strange direction? A little crookedness in a single tooth often resolves as more adult teeth come in and push things into place. Consistent crowding across multiple teeth is a different story.
The bite when the mouth is closed. Is the upper jaw sitting outside the lower jaw all the way around, or does one side cross over? A crossbite at age 8 is easier to address than the same crossbite at 14.
Habits. Thumb-sucking and tongue-thrust patterns still active at this age can reshape the palate over time. If your kid is still sucking their thumb at 8, mention it. There are gentle interventions that don’t involve braces.
Most 8-year-olds still don’t need anything beyond monitoring. If your child had a clean evaluation at 7, age 8 is typically a check-in, not a decision year.
Age 9: When Phase 1 Decisions Get Made
Nine is the age where, for kids who do need early care, the conversation usually shifts from “let’s watch” to “let’s do something now.”
Why 9? Two reasons. First, more permanent teeth are in, so we have a clearer picture of how everything is going to fit. Second, the jaw is still actively growing, which means an expander or partial braces can guide that growth in ways they can’t do once growth slows down.
Phase 1 care at this age typically lasts 6 to 12 months. The goal isn’t a perfect smile yet. It’s about correcting a specific problem (a crossbite, a narrow palate, severe crowding that’s blocking incoming teeth) so that the standard treatment later, if it’s needed, is shorter and simpler.
For the kids who don’t need Phase 1, age 9 is still mostly a monitoring year. You might leave the appointment with a sense of what’s coming. “Looks like she’ll be a candidate for full braces around 12” gives you a real timeline to plan around.
Age 10: The “Pre-Braces” Sweet Spot
Ten is the planning year. Most kids at this age have a mix of permanent front teeth, canines pushing through, and a clearer picture of how the adult bite is setting up. But not quite all the teeth needed for full braces are in.
For families thinking about full braces or Invisalign, age 10 is when we typically map out the timeline. We can usually predict within 6 months when treatment will be ready to start, what we’ll be addressing, and roughly how long it’ll take.
This is also a common age for kids who had Phase 1 care to be in their resting period. They finished an expander or partial braces at 8 or 9, and now they’re waiting for more permanent teeth to come in before standard treatment.
Most 10-year-olds aren’t ready to start braces yet. But this is the age where parents start asking real planning questions, and we can give real planning answers.
Age 11: Most Permanent Teeth Are In
Eleven is when things shift. By this age, most kids have most of their permanent teeth (the second molars are often the holdout). That means the bite is finally fully visible to evaluate, and full braces become a realistic option.
A meaningful share of the standard-treatment cases we start each year start at age 11. Why? Because the timing lines up. Teeth are in, jaw is still growing enough to work with, and kids at this age are usually old enough to manage their own braces care (brushing carefully, avoiding certain foods, wearing their elastics).
If you’re at this age with your kid and haven’t seen an orthodontist yet, you’re not behind. Eleven is squarely inside the normal range for a first evaluation. You can come in fresh and have a useful conversation.
Age 12 to 13: Peak Braces Years
If we had to pick the most common years to start braces in our practice, it would be 12 and 13. By this age the second molars are usually in (or close), the bite is fully readable, and there’s still enough jaw growth left to work with.
This is also the social sweet spot. Most kids’ friends are either getting braces or already have them, so the experience feels normal. Treatment duration is typically 12 to 24 months at this age, which usually lines up with finishing sometime in middle school.
What we see most often at 12 and 13: crowding (permanent teeth ran out of room), spacing (gaps that aren’t closing on their own), and bite issues (overbite, underbite, or open bite that didn’t resolve as the jaw grew). For most cases starting at this age, treatment is straightforward and outcomes are excellent.
What About Ages 14+? Late Starters and Catch-Up Care
If your child is 14, 15, or 16 and you haven’t started braces yet, the honest truth is: you’re fine. You’re not late. Late teens and adults are an increasing share of orthodontic care, and outcomes at these ages are still very good.
A few things to know about starting in the mid-teens. Treatment may take slightly longer because the jaw is growing more slowly. Where a 12-year-old might be in braces 18 months, a 15-year-old might be in braces 20 to 24 months for a similar case. Some growth-dependent corrections become less of an option once jaw growth slows down, but they can still be addressed with a different approach.
Aligner-style options work well at this age, and many teens prefer them for look-and-feel reasons. The window for orthodontic care doesn’t snap shut at 14. It changes shape, but it stays open.
Phase 1 vs Phase 2 (and Why Some Kids Need Both)
You’ve seen Phase 1 mentioned at a few ages above. Here’s the short version of how the two stages relate.
| Factor | Phase 1 (Early Care, Ages 7-10) | Phase 2 (Standard Braces, Ages 11-14) |
|---|---|---|
| Teeth present | Mix of baby + permanent | Most or all permanent teeth |
| Primary goal | Correct a specific issue while the jaw is growing | Align all permanent teeth and finalize the bite |
| Common tools | Expanders, partial braces, space maintainers | Full braces or Invisalign |
| Duration | 6 to 18 months | 12 to 24 months |
| Who needs it? | About 1 in 5 of the kids we evaluate at age 7 | Most kids who need orthodontic care |
| Followed by | Usually a resting period, then Phase 2 | Retainers to maintain results |
Phase 1 is not “early braces.” It’s a targeted intervention for a specific problem. A kid who needs Phase 1 at 8 won’t necessarily need Phase 2 at 12. About half the time they do; the other half, the Phase 1 work resolves the issue and standard braces aren’t needed.
Frequently Asked Questions
Is age 7 too young to start braces?
For most kids, yes. Age 7 is the recommended age for a first orthodontic evaluation, not for starting braces. The vast majority of 7-year-olds are evaluated, monitored, and not actively treated. About 1 in 5 of the kids we see at this age have a specific issue (typically a crossbite or significant crowding) that benefits from Phase 1 care, but even Phase 1 isn’t the same as full braces.
What’s the best age to get braces?
For most kids, ages 11 to 13 hit the practical sweet spot. By that age, most permanent teeth are in, the bite is readable, and there’s still enough jaw growth for treatment to work efficiently. But “best” depends on the issue being addressed. A kid with a crossbite might be best served by starting Phase 1 care at 8, while a kid with simple crowding might be best at 12.
My child is 10 and the dentist says no braces yet. Is that right?
Probably, yes. Age 10 is often the planning year, not the starting year. Most 10-year-olds are still waiting for the canines and second molars to come in, which means starting full braces too early can mean a longer overall treatment time. If your dentist or orthodontist is recommending waiting a year, that’s usually a good call. They’re timing it for efficiency.
Can my 14-year-old still get braces?
Yes. Fourteen is well inside the normal range, and outcomes are excellent.
Why do orthodontists keep telling us to come back every 6 months without doing anything?
Because we’re tracking how the bite is developing in real time, and timing matters more than you’d think.
Between ages 7 and 11, your child’s mouth is changing constantly. Baby teeth fall out, permanent teeth come in, the jaw grows, and the bite shifts. A pattern that looked concerning at 8 might resolve completely by 10. A pattern that looked fine at 9 might become a clear issue by 11. We need to see how those changes are happening to know what to recommend.
Equally important: we want to avoid treating issues that would resolve on their own. Aggressive early intervention on a self-correcting problem means a kid wears appliances they didn’t actually need.
So the 6-month visits are real work, even when nothing visible happens. Most families who come in for evaluations during these years end up being grateful for the watchful waiting later, especially when their kid’s treatment ends up shorter and simpler because the timing was right.
Does the age my child starts braces affect how long they’ll need them?
Sometimes, slightly. Kids who start at the earlier end of standard treatment (ages 11 to 12) sometimes finish a touch faster than kids who start at 14 or 15, because the jaw is still helping the teeth move. But the bigger driver of treatment length is the complexity of the issue being treated, not the starting age. A simple alignment at 14 will finish faster than a complex bite correction at 11.
