Orthodontic treatment duration differs from patient to patient, but most people wear braces or clear aligners for 12 to 36 months. The exact timeline depends on several key elements, including the complexity of the orthodontic case, the patient’s age, and their compliance with instructions. Adolescents often experience more rapid movement because their jaws are still developing, making tooth repositioning easier and more efficient. Mature individuals may require a longer timeframe due to non-growing skeletal structures, yet many still attain outstanding outcomes.

Mild alignment issues, such as slight overcrowding or small diastemas, may be corrected in as little as six months. Severe malocclusions, including pronounced overcrowding, excessive upper tooth coverage, reverse bites, or arch imbalance, often require a minimum of two years of active correction.

The type of orthodontic device used also affects treatment speed. Standard bracket systems tend to move teeth more efficiently for substantial repositioning, while removable plastic appliances may need more months depending on daily usage habits. To remain on track, patients must wear aligners 20 to 22 hours daily.

Once active correction ends, patients transition into the stabilization phase. This phase requires wearing a stabilizing device to maintain alignment. Initially, retainers are typically worn day and night for the initial phase, then worn just while sleeping. Neglecting this step risks teeth relapsing, effectively wasting the entire effort.

Regular checkups every 28–56 days are essential to track progress and fine-tune appliances. Maintaining excellent oral hygiene and avoiding hard, sticky, or chewy foods minimizes setbacks. Patients who skip scheduled visits or don’t comply with protocols often prolong their correction period.

Ultimately isn’t simply to achieve a cosmetic fix, but to create a stable, healthy bite. Dedication and 表参道 歯並び矯正 discipline are the most important factors. Your orthodontist will offer a personalized timeline based on your specific condition, and strictly adhering to their advice is the most reliable path to timely completion.
