Average Braces Treatment Time
Most braces treatments fall within the 12 to 24 month range. This is the figure most orthodontists give at the initial consultation, and it applies to the majority of adolescent and adult patients with moderate alignment or bite issues.
However, average treatment time varies depending on what needs to be corrected. A patient with mild crowding in the front teeth will wear braces for a much shorter period than a patient with a severe overbite combined with crowding and rotated teeth. Your orthodontist will give you a more specific estimate after examining your teeth, taking X-rays, and creating a treatment plan.
It is also worth noting that the initial estimate is just that: an estimate. Treatment may take slightly longer or shorter than predicted depending on how your teeth respond to the forces applied by the braces.
How Long Do Braces Take by Case Type?
The type and severity of your orthodontic problem is the single biggest factor determining how long you will wear braces.
Mild Cases: 6 to 12 Months
Mild cases involve minor crowding, small gaps, or slight rotations of one or two teeth. These cases require relatively small tooth movements and can often be completed in 6 to 12 months. Some mild cases can also be treated with clear aligners instead of traditional braces, which may offer a similar or slightly shorter timeline.
Moderate Cases: 12 to 18 Months
Moderate cases involve noticeable crowding, spacing, or a mild to moderate overbite, underbite, or crossbite. These are the most common cases in orthodontic practice. Treatment requires moving multiple teeth into new positions and may involve extracting one or more teeth to create space. The 12 to 18 month range applies to most patients in this category.
Severe Cases: 18 to 30+ Months
Severe cases involve significant skeletal discrepancies (jaw size or position problems), severe crowding, impacted teeth, or complex bite issues that require moving teeth over longer distances. These cases may require extractions, temporary anchorage devices (TADs), or even surgical correction of the jaw (orthognathic surgery) in combination with braces.
Patients with severe underbites or open bites typically fall into this longer treatment window. If jaw surgery is part of the plan, braces are usually worn for 12 to 18 months before surgery and 6 to 12 months after surgery for final alignment, which means the total time in braces can exceed 30 months.
Factors That Affect How Long You Wear Braces
Several factors beyond case severity influence your overall treatment time.
Age
Teeth tend to move faster in children and adolescents because their jawbones are still growing and are less dense than adult bone. Adult patients can absolutely achieve excellent results with braces, but treatment often takes several months longer than it would for a teenager with the same issue. Adults also have a higher likelihood of needing additional procedures like extractions or minor surgical exposure of impacted teeth.
Patient Compliance
Compliance is one of the few factors you can control. Your orthodontist may ask you to wear rubber bands (elastics), headgear, or other appliances for a specific number of hours per day. These appliances apply forces that braces alone cannot, particularly for correcting bite problems.
Not wearing elastics as directed is one of the most common reasons treatment takes longer than planned. Similarly, missing scheduled appointments delays adjustments and extends treatment. Broken brackets from eating prohibited foods (hard candy, ice, popcorn kernels) require repair appointments that add time.
Type of Braces
Traditional metal braces, ceramic braces, lingual braces (placed behind the teeth), and clear aligners all move teeth differently. Metal braces are generally the most efficient for complex movements. Ceramic braces work similarly to metal but may require slightly more care to avoid breakage. Clear aligners work well for mild to moderate cases but may take longer for complex tooth movements. Your orthodontist will recommend the type best suited to your case and timeline.
Individual Biology
Every person's teeth and bone respond differently to orthodontic forces. Some patients' teeth move quickly with minimal discomfort. Others require longer treatment despite following all instructions. Bone density, root length, gum health, and genetic factors all play a role. This biological variability is why treatment time estimates are ranges, not guarantees.
Can You Speed Up Braces Treatment?
Patients frequently ask whether they can shorten their time in braces. There are both practical steps and clinical technologies that may help.
What You Can Do
The most effective way to avoid delays is to follow your orthodontist's instructions precisely. Wear elastics for the recommended hours, attend all scheduled appointments, avoid foods that can damage brackets, and maintain good oral hygiene. Poor oral hygiene can cause swollen gums that slow tooth movement, and severe cavities during treatment can require pausing orthodontic work while the cavities are treated.
Accelerated Orthodontic Techniques
Some orthodontists offer techniques designed to speed up tooth movement. These include micro-osteoperforation (small perforations in the bone that stimulate a healing response and faster tooth movement), high-frequency vibration devices, and surgical approaches like corticotomy-assisted orthodontics. Evidence for these methods is still developing. Some studies show modest time savings of 30% to 50% for certain cases, while others show minimal benefit. Discuss with your orthodontist whether any of these options are appropriate for your situation.
Phase 1 and Phase 2 Orthodontic Treatment
Some children begin orthodontic treatment in two phases, which affects the total time in braces across childhood and adolescence.
Phase 1 (Early Treatment): Ages 7 to 10
Phase 1 treatment addresses specific problems while the child still has a mix of baby and permanent teeth. Common Phase 1 goals include expanding a narrow palate, correcting a crossbite, creating space for crowded permanent teeth, and guiding jaw growth. Phase 1 typically uses expanders, partial braces, or other appliances and lasts 6 to 12 months.
After Phase 1, the child enters a resting period where they wear a retainer and the remaining permanent teeth erupt. This break typically lasts 1 to 3 years.
Phase 2 (Full Braces): Ages 11 to 14
Phase 2 begins once all or most permanent teeth have erupted. Full braces are placed on all teeth to finalize alignment and bite correction. Phase 2 typically lasts 12 to 24 months. Because Phase 1 addressed the major structural issues, Phase 2 is often shorter and more straightforward than it would have been without early intervention.
Not every child needs two-phase treatment. Many orthodontists prefer to wait and begin treatment with full braces when all permanent teeth are in, typically between ages 11 and 14. Your orthodontist will recommend the approach that best fits your child's specific situation.
Retainers After Braces: How Long Do You Wear Them?
Getting your braces off is not the end of orthodontic treatment. Retention is a critical phase that prevents teeth from shifting back toward their original positions, a natural tendency called relapse.
Most orthodontists recommend wearing removable retainers full-time (20 to 22 hours per day) for the first 3 to 6 months after braces removal. After that initial period, you typically transition to nighttime-only wear. Many orthodontists now recommend wearing retainers at night indefinitely, as teeth can continue to shift throughout life.
Some patients receive a permanent (bonded) retainer, a thin wire glued to the back of the front teeth. Bonded retainers stay in place continuously and are not visible from the front. They require extra attention when flossing and may need occasional repair if the wire loosens or breaks.
What Happens If You Stop Wearing Your Retainer?
Teeth that are not retained can shift noticeably within weeks to months after braces removal. The degree of relapse varies by patient, but it is common enough that orthodontists consider retention a permanent part of the treatment plan. If you have stopped wearing your retainer and notice shifting, contact your orthodontist. In some cases, a new retainer can hold the teeth in their current position. In others, limited retreatment with braces or clear aligners may be needed.
When to See an Orthodontist
The American Association of Orthodontists recommends that every child have an orthodontic evaluation by age 7. This allows the orthodontist to identify developing problems early and determine whether Phase 1 treatment is needed or whether it is best to monitor and wait.
Adults considering braces should schedule a consultation whenever they are ready. There is no upper age limit for orthodontic treatment. During the consultation, the orthodontist will examine your teeth and bite, take X-rays and photos, and provide an estimated treatment timeline and cost.
