Most kids complete orthodontic treatment in 12 to 24 months. Mild cases involving minor crowding or spacing may wrap up in 6 to 12 months, while more complex bite issues can extend treatment to 24 to 36 months. Two-phase treatment plans span longer because they include a resting period between phases. Your child’s specific timeline depends on the severity of their alignment issues, their growth stage, and how well they follow care instructions at home.
No two smiles follow the exact same path. Some kids need a quick tune-up. Others benefit from a longer, more involved treatment plan. At Speaks Ortho, we take the time during your complimentary exam to map out what your child actually needs, no guesswork involved. We want Denver families to feel informed and confident before any treatment starts.
What Are the Stages of a Child’s Orthodontic Treatment?
Children’s orthodontic treatment generally involves four stages: Phase 1 (6 to 12 months of early interceptive care), a resting period for monitoring growth, Phase 2 (12 to 24 months of full alignment work), and a retention phase requiring long-term retainer wear. The total timeline varies by case, but most kids spend between one and four years in active orthodontic care.
What Happens in Phase 1 (Early or Interceptive Treatment)?
This stage typically happens between ages 7 and 10, lasting 6 to 12 months. Phase 1 focuses on addressing specific issues while your child’s jaw is still growing. Common goals include correcting crossbites, creating space for incoming teeth, or breaking habits like thumb-sucking. Because the bones are still flexible, early action often prevents bigger problems later.
What Is the Resting Period?
After Phase 1, your child enters a monitoring phase. We watch how their permanent teeth come in and how their jaw develops. This period can last a year or more. No active treatment happens during this time, just periodic check-ins to track progress.
What Happens in Phase 2 (Full Treatment)?
This is what most people picture when they think of braces. Phase 2 typically starts around age 11 or later, once most permanent teeth have emerged. Treatment usually runs 12 to 24 months. The goal is full alignment of all teeth and proper bite function.
How Long Is the Retention Phase?
After active treatment ends, retainers keep teeth in their new positions. Your child will wear retainers long-term, often nightly for years, to maintain their results.
Throughout active treatment, expect adjustment visits every 4 to 8 weeks. These appointments keep everything on track and let our team make small tweaks as your child’s smile shifts into place.
Why Starting Orthodontic Treatment Early Can Shorten Timelines
Early intervention works with your child’s natural growth instead of against it. When we address problems while jaw bones are still developing, we can guide growth in the right direction. Dr. Speaks, who is Board-Certified by the American Board of Orthodontics, has worked with many Denver kids whose timelines were shortened simply by starting at the right age.
Here’s what early treatment can accomplish:
- Guides jaw development while bones remain flexible and responsive
- Creates room for adult teeth by addressing crowding before it becomes severe
- Corrects crossbites and underbites before they cause lasting skeletal changes
- Breaks habits like thumb-sucking or tongue thrusting that affect tooth position
- Shortens Phase 2 treatment since much of the groundwork is already done
According to the American Association of Orthodontists, children should have their first orthodontic evaluation by age 7 . This timing catches problems early, even if treatment doesn’t start right away.
Early evaluation gives your orthodontist the chance to monitor growth and step in at the right moment. Sometimes that means starting treatment. Other times it means watching and waiting until the time is right.
How Long Do Braces vs. Clear Aligners vs. Two-Phase Treatment Take?
Different treatment approaches come with different timeframes. Here’s a general breakdown:
Clear aligners can work well for kids, but they require commitment. Your child needs to wear them 20 to 22 hours daily for treatment to stay on schedule. Braces stay put, which can be an advantage for younger patients who might forget to pop aligners back in after meals.
Dr. Speaks can help you figure out which option fits your child’s needs and lifestyle during a complimentary exam.
Factors That Affect How Long Orthodontic Treatment Takes for Kids
Several variables influence your child’s treatment timeline. Some are outside your control. Others depend on daily habits.
Clinical Factors:
- Severity of crowding, spacing, or bite misalignment
- Your child’s age and current growth stage
- The treatment method selected (braces tend to handle complex movements well; aligners do well with certain cases)
- How teeth need to be guided into their new position
Compliance Factors:
- Wearing elastics as directed (skipping them adds months)
- Keeping aligners in for the required hours each day
- Avoiding foods that break brackets
- Showing up for scheduled adjustment appointments
Health Factors:
- Overall dental health during treatment
- Oral hygiene habits (cavities or gum issues can pause treatment)
- Any underlying conditions affecting bone or tooth development
Kids who follow instructions closely and keep their teeth clean tend to finish on time, or even early. Missed appointments and broken brackets push timelines back, so consistency really pays off.
When Should Your Child Start Orthodontic Treatment?
Your child should have their first orthodontic evaluation around age 7. At this age, enough permanent teeth have emerged for an orthodontist to spot developing issues like crossbites, crowding, or jaw growth problems. Early evaluation doesn’t always mean early treatment. It gives your orthodontist the chance to monitor growth and step in at the right time.
Signs that warrant an evaluation:
- Crowded or overlapping teeth. When teeth don’t have enough room, they twist or stack on top of each other. Catching this early can prevent more involved treatment down the road.
- Teeth that don’t meet properly when biting. Bite problems can wear down enamel and make chewing uncomfortable over time.
- Crossbite (upper teeth sitting inside lower teeth). Left alone, crossbites can shift jaw growth in the wrong direction.
- Persistent thumb-sucking past age 5. Prolonged sucking habits push teeth out of position and can change the shape of the palate.
- Mouth breathing or snoring. These signs may point to airway or jaw development concerns worth a closer look.
- Early or late loss of baby teeth. Timing matters because baby teeth hold space for the adult teeth coming in behind them.
- Difficulty chewing or biting. Trouble with everyday meals often signals a bite that needs attention.
Not every 7-year-old needs braces. Many kids just need monitoring until more permanent teeth arrive. A complimentary exam at Speaks Ortho helps Denver families understand whether their child needs treatment now, later, or not at all.
Frequently Asked Questions About Kids’ Orthodontic Timelines
Can kids’ braces be done in under a year?
Yes, in some cases. Mild crowding or spacing issues may only need 6 to 12 months of treatment. Most kids, though, fall into the 12 to 24 month range. The only way to know your child’s specific timeline is through an evaluation with our team at Speaks Ortho.
Does treatment take longer for younger kids?
Not necessarily. Younger kids in Phase 1 treatment often have shorter active treatment periods (6 to 12 months). But if they need Phase 2 later, the total span of orthodontic care extends over several years with a resting period in between.
Do clear aligners work faster than braces for children?
Clear aligners can be efficient for the right cases. They typically take 12 to 18 months for mild to moderate issues. Speed depends heavily on wear time, though. Kids who don’t wear aligners consistently will see slower progress than those with traditional braces.
What happens if my child doesn’t wear their elastics or aligners?
Treatment takes longer. Elastics correct bite issues, and skipping them stalls progress. Aligners need 20 to 22 hours of daily wear to work properly. Inconsistent wear can add weeks or months to your child’s treatment plan.
How long will my child need to wear a retainer?
Retainers are a long-term commitment. Most orthodontists recommend nightly wear indefinitely to prevent teeth from shifting back. Some patients transition to wearing retainers a few nights per week after the first year, but this varies from one child to the next.
Can missing appointments extend treatment time?
Yes. Adjustment appointments keep treatment moving forward. Missing or rescheduling frequently can add months to the overall timeline. Our team at Speaks Ortho recommends keeping appointments every 4 to 8 weeks as scheduled, since steady progress depends on those regular check-ins.
