How Long Do Braces Take?
Average Time for Braces Treatment
How long do braces take? The answer depends on your child’s specific case, but the average time for braces treatment is typically between 18 and 24 months. This is based on the severity of misalignment, the type of braces used, and how consistently patients follow their orthodontist’s instructions.
“How long do braces take?”
It’s the first question most parents ask at an orthodontic consultation—and understandably so. You’re planning around school schedules, sports seasons, family photos, and a teenager who wants the answer as much as you do.
The honest answer is that treatment time varies. But it doesn’t vary randomly. It follows predictable patterns based on factors your orthodontist can identify and explain during a thorough evaluation.
When looking at braces treatment duration for children, kids, and teens often experience faster results than adults because their jaws are still developing. A well-planned orthodontic treatment timeline for kids usually includes consultation, appliance placement, active treatment, and a retention phase.
What Is the Average Time for Braces for Kids and Teens?
According to Mayo Clinic, orthodontic treatments like braces typically take between 1 and 3 years, depending on the complexity of the case.
There’s no single answer that applies to every child, but there are reliable ranges.
Most patients wear braces for 18–24 months, but treatment can range from 6 months for minor cases to 36 months for complex issues. The more crooked or crowded the teeth are, the longer the braces treatment takes.
For children and teens, here’s a practical breakdown by treatment type:
Traditional Metal Braces — 18 to 24 months
The most reliable option for complex cases. Metal braces work continuously and don’t depend on patient compliance with removal, making them well-suited for younger patients or more involved cases.
Damon System Braces — 15 to 20 months
The Damon System’s self-ligating technology reduces friction during tooth movement. Cases that might take 22 months with traditional braces often complete more quickly with a self-ligating system, and fewer appointments may be needed for adjustments. For active Montana families with packed schedules, this efficiency has real value.
Clear Aligners — 12 to 18 months
Suitable for mild to moderate alignment cases. The average time for braces treatment is highly dependent on compliance — aligners must be worn 20–22 hours per day to stay on schedule. Teens who frequently remove their aligners will experience delayed results.
The American Association of Orthodontists recommends that children have their first orthodontic evaluation by age 7 to identify potential issues early.
Factors Affecting Braces Duration
Several key factors affecting braces duration include:
- Severity of misalignment
- Age and jaw development
- Type of braces or aligners used
- Patient compliance (rubber bands, aligner wear)
- Oral hygiene and appointment consistency
6 Key Factors That Determine How Long Your Child’s Braces Treatment Takes
1. Severity and Complexity of the Case
This is the single biggest variable.
Minor misalignments like gapping or crowding might only require braces for 12–18 months. Conversely, more severe issues like rotations, deep bites, or open bites can take 24–30 months or even longer to correct.
A child with mild crowding in the front teeth has a fundamentally different treatment timeline than one with a significant overbite, underbite, crossbite, or multiple rotated teeth. Your orthodontist’s first task is assessing where your child’s case falls on this spectrum.
2. Your Child’s Age and Jaw Development
Children and teens whose jaws are still actively growing typically respond faster to orthodontic treatment than adults with fully set bone structure.
Because a child’s jaw is still growing and developing, the teeth tend to reposition more quickly. The average length of braces treatment for kids tends to be 15–18 months.
This is one reason why starting treatment at the right developmental stage — typically between ages 9 and 14 for comprehensive Phase 2 treatment — optimizes both speed and outcome.
3. Whether Phase 1 Early Treatment Was Done
If your child had Phase 1 interceptive treatment (usually between ages 7–10) with a palate expander or partial appliance, they arrive at Phase 2 with many structural issues already addressed.
A child who had Phase 1 early intervention comes into Phase 2 with a jaw that’s already the right size and in the right position. Phase 2 for that child is often 12 to 14 months. A child who didn’t have Phase 1 and needs more comprehensive correction in Phase 2 might take 20 to 24 months for the same end result.
This is why the age 7 evaluation — recommended by the American Association of Orthodontists — can directly impact how long your child ultimately wears braces.
4. Patient Compliance — The Factor Families Control
This is the variable that parents and children can actually influence.
For children in traditional or Damon braces, compliance means wearing rubber bands exactly as prescribed, avoiding foods that break brackets, maintaining good oral hygiene, and attending every scheduled appointment.
Braces work by applying gentle, controlled pressure to move teeth into their desired positions. Skipping wear time or neglecting to replace elastics can significantly extend treatment duration.
For clear aligner patients, compliance is even more critical. Aligners that spend time in a backpack instead of in the mouth simply don’t move teeth. Every day of underuse extends the timeline.
Missed appointments also add time. Each skipped adjustment visit can push the final date back by weeks.
5. Oral Hygiene During Treatment
Poor oral hygiene during orthodontic treatment can slow progress and even pause it. When teeth and gums are inflamed from inadequate brushing and flossing, the body’s response to tooth movement changes — and the process slows down.
Children who keep their teeth clean throughout treatment consistently finish closer to their estimated timeline than those who struggle with hygiene around their braces.
6. Type of Braces and Technology Used
At Pediatric Dentistry & Orthodontics, Dr. Dawson uses advanced digital technology — including 3D computer imaging and intraoral scanners — to plan treatment precisely before a single bracket is placed. This level of accuracy from the start is one of the most underappreciated factors in keeping treatment efficient.
The Orthodontic Treatment Timeline: What Each Phase Looks Like
Here’s what the journey from consultation to finished smile actually involves:
Week 1 — Initial Consultation Digital X-rays, 3D scans, photographs, and a personalized treatment plan. For most families, this consultation is complimentary. This is when your child gets their personalized timeline estimate.
Weeks 2–4 — Records and Appliance Placement Custom braces brackets are bonded to the teeth, or aligner trays are fabricated and fitted. The process takes 1–2 hours and is not painful, though some soreness over the following days is normal as teeth begin to adjust.
Months 1–20 — Active Treatment Phase This is the longest phase. Adjustment appointments occur every 6–10 weeks for braces patients. Each visit involves wire changes, rubber band checks, and monitoring of progress. Clear aligner patients receive their next set of trays and have check-in appointments at similar intervals.
Most patients notice the biggest visible changes in the first few months as significantly crowded or misaligned teeth begin moving into position.
Months 18–24 — Refinements As treatment nears completion, the focus shifts to fine-tuning. Minor tooth positions are adjusted, bite relationships are perfected, and preparation begins for removing the braces.
End of Active Treatment — Debanding and Retainers Braces are removed and retainers are fitted the same day. This appointment is often one of the most anticipated of the entire process.
Retention Phase — Ongoing Retainers are not optional. They are part of treatment.
Retainers are not optional after braces — they’re part of the treatment. Teeth will shift back toward their original positions if not held in place after braces come off. Most patients wear retainers full-time for the first few months, then nights-only indefinitely.
Skipping retainer wear is the most common reason teeth relapse after orthodontic treatment. The active phase has an endpoint. The retention phase doesn’t — it becomes a permanent nightly habit, as routine as brushing.
How Long Do Metal Braces Take?
If you’re wondering how long do metal braces take, traditional braces generally require 18 to 24 months, making them ideal for moderate-to-severe alignment issues.
Can Braces Treatment Be Made Faster?
This is a common question from teens who want the braces off as quickly as possible.
The honest answer: treatment cannot be safely accelerated beyond what the biology of tooth movement allows. Rushing risks root damage, bone loss, and unstable results.
What families can do to keep treatment on the most efficient possible timeline:
- Wear rubber bands exactly as prescribed — every day, not just before appointments
- Attend every scheduled adjustment — don’t reschedule unless absolutely necessary
- Brush and floss properly around brackets
- Avoid foods that break brackets (hard candy, ice, popcorn, sticky foods)
- For clear aligner patients: keep aligners in for the full 20–22 hours per day
These habits won’t shave months off a complex case, but they consistently prevent the delays that push treatments past their estimated completion date.
Common Myths About Braces Treatment Time — Cleared Up
“Braces always take 2 years.” Not true. Many cases finish in 12–18 months. Some complex cases take longer. The right answer is specific to your child’s case.
“Clear aligners are always faster than braces.” Only for mild to moderate cases — and only when worn as directed. For complex cases, traditional or Damon braces are often faster.
“Once braces are off, it’s over.” Braces coming off is the end of the active phase, not the end of treatment. Retainer wear is what locks in the result permanently.
“Missing one appointment doesn’t matter much.” It matters more than most families expect. One missed appointment can shift the completion date back by 4–6 weeks, especially during critical phases of tooth movement.
How Much Do Braces Cost?
Orthodontic treatment typically ranges from $3,000 to $7,000 depending on treatment type, case complexity, and duration. Most insurance plans with orthodontic coverage offset a portion of this cost, and flexible in-house payment plans are widely available.

Frequently Asked Questions — How Long Do Braces Take
How long do metal braces take for kids?
Traditional metal braces for children and teens typically take 18 to 24 months, depending on case complexity. Mild cases may finish in 12–18 months; severe cases involving bite correction can take up to 30 months. Your orthodontist will provide a personalized estimate after reviewing X-rays and a clinical exam.
How long do clear aligners take for teens?
Clear aligner treatment for teens typically takes 12 to 18 months for mild to moderate cases. The timeline depends heavily on compliance — aligners must be worn 20–22 hours per day to stay on schedule. Consistent wear is the single most important factor for aligner patients.
Does the Damon System make braces faster?
The Damon System’s self-ligating design reduces friction during tooth movement, which can shorten treatment time compared to traditional braces in many cases — often by several months. It also typically requires fewer adjustment appointments, which is practical for busy families.
What happens if my child misses orthodontic appointments?
Missed appointments slow progress and can extend total treatment time by weeks or months. If an appointment must be rescheduled, contact our office as soon as possible to minimize the delay.
How long must retainers be worn after braces?
Most orthodontists recommend full-time retainer wear for the first few months after braces, transitioning to nightly wear indefinitely. Without consistent retainer use, teeth gradually shift back — potentially requiring repeat treatment. Retainer wear is a permanent, nightly habit, not a temporary one.
My child had Phase 1 treatment — do they still need braces?
Possibly, yes — but likely for a shorter time. Phase 1 addresses structural issues like jaw size and spacing while a child is still growing. Phase 2 braces then refine tooth alignment once permanent teeth have arrived. Children who completed Phase 1 treatment often need Phase 2 for only 12–14 months.
