Quick answer: The best age to get braces is usually between 10 and 14, when most permanent teeth have erupted and the jaw is still growing — which makes treatment faster and more effective. But the first orthodontic evaluation should happen much earlier, by age 7, according to the American Association of Orthodontists (AAO). And there is no upper age limit: adults of any age can get braces or clear aligners as long as their teeth and gums are healthy. The “best” age is less about a birthday and more about dental development, jaw growth, and the specific problem being corrected.
The Short Answer: There Is No Single “Best” Age
If you search for the best age to get braces, you will find a different number on almost every website — 10, 11, 12, 13, or 14. That is because there is no single age that fits everyone. The right time depends on how your teeth and jaws are developing, what orthodontic problem is present, and your personal goals.
What the evidence does agree on is this:
- Age 7 is the best time for the first orthodontic evaluation — not necessarily for braces, but for a check-up that spots problems early.
- Ages 10–14 are the most common and effective years for full braces, because most permanent teeth are in and the jaw is still growing.
- Adults can get braces at any age. The AAO states that age is rarely a deciding factor for orthodontic treatment, as long as the teeth and gums are healthy.
In other words, the question is not really “what age should I get braces?” but “what stage of dental development am I (or my child) in, and what needs correcting?” This guide walks through every age group, what happens at each stage, how long treatment takes, what it costs, and how to tell whether it is time to book an evaluation.
What the Experts Recommend: The Age 7 Evaluation
The American Association of Orthodontists recommends that every child have their first orthodontic screening by age 7. That surprises many parents — after all, a 7-year-old still has plenty of baby teeth. But age 7 is a diagnostic window, not a treatment deadline.
By age 7, children are entering the “mixed dentition” phase: they have a combination of baby teeth and their first permanent molars and incisors. That is enough for an orthodontist to see how the jaws are growing and whether bite or alignment problems are developing. At this visit, the orthodontist can:
- Check how the upper and lower jaws line up
- Spot crowding, spacing, or teeth coming in the wrong direction
- Identify harmful habits such as thumb sucking or tongue thrusting
- Detect crossbites, underbites, or open bites early
- Decide whether to simply monitor growth or start early interceptive treatment
For most children, the age-7 visit ends with “everything looks fine — let’s check again in a year or two.” Only a minority need treatment at that age. But catching a serious problem at 7 instead of 12 can mean simpler treatment, fewer extractions, and sometimes avoiding jaw surgery later.
Key point: an evaluation at age 7 does not mean braces at age 7. It means a professional is watching growth while there is still time to guide it.
The Best Age for Braces at Every Life Stage
The table below summarises what typically happens at each stage, what treatment is common, and how long it usually takes.
| Age group | Dental stage | Typical action | Typical treatment time |
|---|---|---|---|
| 6–7 years | Mixed dentition begins; first permanent molars and incisors erupt | First orthodontic evaluation (AAO recommendation) | Evaluation only for most children |
| 7–10 years | Mixed dentition; jaw still growing fast | Early interceptive treatment (Phase 1) only if a specific problem needs it | 6–12 months for Phase 1 |
| 10–14 years | Most permanent teeth erupted; jaw still growing | Full braces — the “sweet spot” for most children | 18–24 months |
| 14–17 years | Jaw growth slowing; all permanent teeth in | Full braces or clear aligners; still highly effective | 18–30 months |
| 18–30 years | Adult dentition; growth complete | Braces or clear aligners; excellent results | 18–36 months |
| 30+ years | Adult dentition | Braces or clear aligners; no upper age limit | 18–36 months |
The rest of this article explains each stage in detail, so you can see exactly where you or your child fits.
Ages 7–10: The First Check and Early (Phase 1) Treatment
Between ages 7 and 10, the jaw is growing quickly and the bone is still soft and responsive. Most children do not need braces at this age, but some benefit from early interceptive treatment — called Phase 1 — that fixes a specific problem while growth can still be guided.
Phase 1 treatment is usually recommended for:
- Severe crossbite — upper teeth biting inside the lower teeth, which can wear teeth unevenly and shift the jaw
- Severe crowding or a narrow upper jaw — a palatal expander can widen the upper jaw while the bones are still flexible
- Protruding front teeth — teeth that stick out are more likely to be chipped or knocked out in a fall or sports injury
- Underbite — the lower jaw growing ahead of the upper jaw
- Harmful habits — persistent thumb sucking or tongue thrusting that is changing how the teeth grow
Phase 1 typically lasts 6–12 months and uses a partial set of braces, an expander, or another appliance. It is not the full treatment. After Phase 1, the orthodontist usually pauses treatment and lets the remaining permanent teeth erupt, then starts Phase 2 (full braces) around ages 11–14 if still needed.
Why not just wait? For the problems listed above, waiting can make treatment harder. A narrow jaw, for example, is far easier to widen at age 8 than at age 14, when the bones have begun to fuse. Early treatment can also reduce the need for tooth extractions or jaw surgery later.
For most children, though, the right answer at ages 7–10 is simply: get the evaluation, then monitor. Starting braces too early for a problem that would have resolved on its own wastes time and money.
Ages 10–14: The Sweet Spot for Full Braces
Most orthodontists consider ages 10–14 the ideal window for full braces. There are three reasons:
- Most permanent teeth have erupted. By around age 12–13, all permanent teeth except wisdom teeth are usually in. The orthodontist can align the complete set in one course of treatment.
- The jaw is still growing. During the pre-teen and early teen years, the jaw bone is still soft and growing, and cellular metabolism peaks during puberty growth spurts. Teeth move faster and more predictably.
- Treatment is shorter. Full braces at this age typically take 18–24 months. Starting later, after growth has finished, the same correction often takes longer.
This is also the age when children are most socially comfortable starting treatment — many of their friends are getting braces too, which removes much of the self-consciousness. And because the jaw is still developing, the orthodontist can guide growth as well as straighten teeth, correcting bite problems that would be much harder to fix in an adult.
The NHS in the UK notes the ideal age is often around 12 or 13, while the mouth and jaws are still growing — although it can be slightly earlier or later depending on the child. Most US practices give the same guidance: roughly 11–14 is when braces are most commonly fitted.
What if my child misses the 10–14 window?
Nothing is lost. Braces work just as well at 15, 16, or 17 — treatment may take a few months longer because jaw growth has slowed, and in some cases an extraction is needed to create space. The 10–14 window is the most efficient, not the only, window.
Ages 15–18: Still a Great Time
Teenagers aged 15–18 are the traditional orthodontic group, and braces remain highly effective in these years. By this age, all permanent teeth are in and the bite is fully formed, so the orthodontist can see exactly what needs correcting.
The main differences from the 10–14 window are:
- Treatment may take slightly longer — typically 18–30 months — because jaw growth has slowed and teeth move a little more slowly.
- Compliance matters more. Clear aligners become a realistic option for responsible teens, but only if the trays are worn 20–22 hours a day.
- Wisdom teeth may need monitoring. An orthodontist will check whether erupting wisdom teeth could crowd the newly aligned teeth.
For many families, ages 15–18 are also when the practical pieces fall into place: dental insurance coverage, a teenager old enough to manage cleaning around brackets, and a schedule that can fit regular appointments.
Adults: Is There an Upper Age Limit for Braces?
There is no upper age limit for braces. Adults in their 20s, 30s, 40s, 50s, and beyond get braces and clear aligners every day. The AAO states that age is rarely a deciding factor — what matters is whether your teeth and gums are healthy enough for tooth movement.
That said, adult treatment has some differences worth knowing:
| Factor | Children and teens (10–14) | Adults (18+) |
|---|---|---|
| Jaw growth | Still growing; growth can be guided | Growth complete; only teeth move, not the jaw |
| Treatment time | Usually 18–24 months | Usually 18–36 months |
| Tooth movement | Faster; bone remodels quickly | Slower; bone is denser |
| Extractions | Sometimes needed | More often needed to create space |
| Gum health | Rarely an issue | Must be checked first; gum disease must be treated before braces |
| Appearance options | Metal or ceramic braces common | Ceramic, lingual, or clear aligners often preferred |
| Cost | Often covered by family dental plans | Usually paid out of pocket |
Adults should know: if you have gum disease, it must be treated before orthodontic treatment begins. Moving teeth in the presence of active gum disease can damage the bone that supports them. A healthy mouth is the only real prerequisite — not a birthday.
Many adults choose clear aligners for professional reasons, but aligners only work if they are worn as directed. Adults who want a fixed option often pick ceramic braces, which blend with the teeth, or lingual braces, which sit behind the teeth.
Phase 1 vs Phase 2: What Is the Difference?
Parents often hear “Phase 1” and “Phase 2” and wonder whether their child needs two rounds of braces. Here is the comparison.
| Feature | Phase 1 (early interceptive) | Phase 2 (full braces) |
|---|---|---|
| Typical age | 7–10 years old | 11–14+ years old |
| Goal | Guide jaw growth; fix a specific problem early | Straighten all permanent teeth; perfect the bite |
| Appliances | Expander, partial braces, habit appliance | Full braces or clear aligners |
| Duration | 6–12 months | 18–24 months |
| Needed by | A minority of children | Most children who need orthodontics |
| Followed by | A resting period while teeth erupt | Retainers to hold the result |
Not every child needs Phase 1. If the age-7 evaluation shows normal growth, the orthodontist will simply monitor and wait for the Phase 2 window. Two-phase treatment costs more overall, so it should only be recommended when early intervention genuinely changes the outcome.
Signs Your Child May Need Braces
You do not need to wait for the age-7 evaluation if you notice any of these signs. Book an orthodontic check sooner if your child has:
- Crowded, overlapping, or crooked teeth
- Teeth that stick out noticeably (protruding front teeth)
- A large gap between teeth that is not closing
- Difficulty chewing or biting food
- Mouth breathing, or breathing through the mouth while sleeping
- Thumb sucking or pacifier use past age 4
- Teeth that meet abnormally, or jaws that shift or click
- Baby teeth lost too early, or baby teeth still present past age 12
- Speech difficulties linked to tooth or jaw position
- A bite where the upper teeth sit inside the lower teeth (crossbite)
Any one of these is a reason for an evaluation — not a diagnosis. Only an orthodontist can say whether treatment is needed and when it should start.
What Happens If You Wait Too Long?
Braces still work at any age, but waiting has real costs:
- Treatment takes longer. After jaw growth finishes, teeth move more slowly and the same correction can take 6–12 months longer.
- Extractions become more likely. A growing jaw can create space naturally; an adult jaw cannot, so teeth may need to be removed to make room.
- Jaw surgery may be needed. Severe bite problems (such as a major underbite) can often be corrected with growth guidance in a child, but may require surgery in an adult.
- Wear and damage accumulate. A bad bite wears teeth unevenly, chips edges, and strains the jaw joint. Years of grinding on a misaligned bite can cause damage that braces alone cannot undo.
- Gum problems increase. Crowded teeth are harder to clean, which raises the risk of gum disease and cavities over time.
None of this means it is ever “too late” — adults get excellent results every day. It means the earlier the evaluation, the more options you keep open.
How Much Do Braces Cost at Each Age?
Cost depends on where you live, the type of braces, and how complex the case is. The figures below are typical US ranges.
| Treatment | Typical cost (US) | Notes |
|---|---|---|
| Metal braces (child/teen) | $3,000–$7,000 | Most affordable; often partly covered by dental insurance for children |
| Ceramic braces | $4,000–$8,000 | Tooth-coloured brackets; popular with teens and adults |
| Clear aligners | $3,000–$8,000 | Removable; depends on the number of aligner sets |
| Lingual braces | $8,000–$10,000 | Hidden behind the teeth; most expensive |
| Phase 1 (early treatment) | $1,000–$3,000 | In addition to Phase 2 if both are needed |
| Retainers after treatment | $150–$500 | Essential — teeth shift back without them |
Children’s braces are more often covered by dental insurance than adult treatment. Many orthodontists offer payment plans, and treatment cost should be discussed at the first consultation — before any commitment. If cost is a barrier, ask about dental schools, which often provide orthodontic treatment at a reduced price under specialist supervision.
Braces vs Clear Aligners at Each Age
| Age group | Best option | Why |
|---|---|---|
| 7–10 (Phase 1) | Braces or expanders | Aligners cannot guide jaw growth the way fixed appliances can |
| 10–14 | Metal or ceramic braces | Most reliable; no compliance risk; fastest for complex cases |
| 15–18 | Braces or clear aligners | Aligners work well for responsible teens who wear them 20–22 hours a day |
| Adults | Clear aligners, ceramic, or lingual braces | Appearance matters more; aligners suit professional life |
The “best” appliance depends on the problem, not just the age. Severe rotations, large bite corrections, and vertical problems are usually handled better with fixed braces. Mild to moderate crowding and spacing often suit aligners well. Your orthodontist will recommend based on your case, not on trends.
How to Choose the Right Time: A Simple Checklist
Use this checklist before booking a consultation:
- Has your child had an orthodontic evaluation by age 7? If not, book one now, whatever their age.
- Are most permanent teeth in (usually by age 12)? If yes, the full-braces window is open.
- Is there a specific problem — crossbite, severe crowding, protruding teeth? If yes, do not wait for the “perfect” age.
- Are teeth and gums healthy? Any cavities or gum disease should be treated first.
- Can you commit to regular appointments (usually every 4–8 weeks) for 18–24 months?
- Does your dental insurance cover orthodontics, and up to what age?
- Is your child (or are you) ready to keep braces clean and follow food and care rules?
If you can tick most of these boxes, it is time to book the consultation. The orthodontist — not a calendar date — makes the final call on timing.
Common Myths About the Best Age for Braces
Myth 1: “Braces are only for children.”
False. Around one in four orthodontic patients today is an adult. Teeth can be moved at almost any age as long as the bone and gum tissue are healthy.
Myth 2: “You must wait until all baby teeth fall out.”
False. The age-7 evaluation exists precisely because some problems are best fixed while baby teeth are still present. Waiting for every baby tooth to fall out can close the window for guiding jaw growth.
Myth 3: “Getting braces too early damages teeth.”
False when treatment is properly planned. Phase 1 treatment is short and targeted. What wastes time is starting full braces years before the permanent teeth are ready — which is why a good orthodontist will often say “not yet” and monitor instead.
Myth 4: “Adults can’t get braces because their teeth won’t move.”
False. Adult teeth move — just more slowly. The limiting factor is gum and bone health, not age.
Myth 5: “The best age is the same for everyone.”
False. Two 12-year-olds can be at very different stages of dental development. Biological development matters more than chronological age, which is why the evaluation matters more than the birthday.
Frequently Asked Questions
What is the best age to get braces for a child?
The best age for full braces is usually 10–14, when most permanent teeth have erupted and the jaw is still growing. But the first orthodontic evaluation should happen by age 7, so any problems are spotted while growth can still be guided.
Is 7 too young for braces?
Age 7 is not too young for an orthodontic evaluation, and a small number of children do need early interceptive treatment (Phase 1) at that age — for example, to correct a severe crossbite or widen a narrow jaw. Most 7-year-olds do not need braces yet; the visit is mainly diagnostic.
Is 16 too old for braces?
No. Braces work very well for 15- and 16-year-olds. The jaw is closer to its final hardened state, so teeth move slightly more slowly and treatment may take 6–12 months longer than it would at age 12, but results are excellent.
Can adults get braces at 30, 40, or 50?
Yes. There is no upper age limit for braces or clear aligners. Adults of any age can be treated successfully as long as their teeth and gums are healthy. Gum disease must be treated first.
What is the best age for braces — 10, 12, or 14?
Most orthodontists agree the sweet spot is between 10 and 13 years. Most permanent teeth have erupted by age 10–11, the jaw bone is still flexible so teeth move faster, and treatment is shorter. Starting at 14 or later is still possible but may take longer and sometimes requires tooth extraction.
How long do braces take at different ages?
At ages 10–14, full treatment typically takes 18–24 months. At ages 15–18, expect 18–30 months. For adults, treatment usually takes 18–36 months, depending on complexity.
Should I get braces or Invisalign?
It depends on your age and your case. Braces are usually better for complex corrections and for younger patients, where compliance is a factor. Clear aligners suit responsible teens and adults with mild to moderate crowding, and they are nearly invisible. Your orthodontist will advise based on your teeth, not on preference alone.
Does getting braces early save money?
Sometimes. Early interceptive treatment can prevent a problem from becoming more expensive later — for example, avoiding extractions or jaw surgery. But two-phase treatment costs more than one phase, so early treatment only saves money when it genuinely changes the outcome. A trustworthy orthodontist will tell you when waiting is the better option.
What happens if I never get braces?
Crooked teeth and a bad bite do not always cause problems, but they can lead to uneven tooth wear, difficulty cleaning (and therefore more cavities and gum disease), jaw pain, and chipped teeth. If your bite is comfortable and you can clean your teeth well, braces are optional — an evaluation will tell you whether treatment is medically useful or purely cosmetic.
The Bottom Line
The best age to get braces is usually 10–14 for full treatment — but the most important age is 7, when the first orthodontic evaluation should happen. That single check-up is what lets an orthodontist catch problems early, guide jaw growth while it is still possible, and time full treatment for the window when it works fastest.
If you are past that window, do not worry: braces work at 16, at 30, and at 60, as long as your teeth and gums are healthy. The worst time to get braces is never — the second-best time is now. Book the evaluation, ask what stage your teeth are at, and let the orthodontist time the treatment to your development, not to a number on a chart.
