How long do braces last?

Most comprehensive braces treatments take approximately 18 to 28 months, but the exact timeline varies from patient to patient. Some limited treatments may take only several months. More complex cases may take longer than two years.

There is no universal braces timeline because every orthodontic case is different. Mild crowding or spacing may be corrected relatively quickly, while bite correction, impacted teeth, severe crowding, missing teeth, jaw growth issues, or surgical orthodontic planning can take longer.

Several factors affect how long braces last.

The starting problem is one of the biggest factors. Aligning slightly crooked front teeth is usually simpler than correcting a deep bite, open bite, underbite, crossbite, or major crowding.

The bite goals also influence the timeline. Patients often notice the front teeth becoming straighter early in treatment, but the bite may still need significant correction. Finishing the bite properly can take time.

Patient cooperation is critical. Wearing elastics as instructed, avoiding broken brackets, maintaining good oral hygiene, and attending appointments all help treatment stay on track.

Broken appliances can delay progress. Hard, sticky, or chewy foods can damage braces and interrupt planned tooth movement. Learn about orthodontic emergencies.

Missed appointments may also extend the timeline. Orthodontic treatment works best when visits happen at the proper intervals.

Biology matters as well. Some teeth move more quickly than others, and every patient responds differently to orthodontic forces. Read more about why treatment sometimes takes longer than expected.

At Orthodontics on Queen in The Beaches, Toronto, patients receive an estimated treatment time before starting braces. This estimate is based on the diagnosis and expected treatment plan. However, orthodontics is a biological process, not an exact delivery schedule.

The goal is not only to finish quickly. The goal is to finish well, with teeth that are aligned, a bite that functions properly, and a result that can be maintained with retainers.
