The length of time a person may need to wear braces varies widely. Treatment length usually ranges between 18 to 32 months. Complex or severe bad bites will take longer to correct. Patients who don’t do their part in cleaning their teeth or in following their orthodontist’s instructions will also require a longer treatment course. Other factors which can prolong treatment duration include unexpected bone growth, abnormal bone, broken braces and missed appointments. Patients who follow all of their orthodontist’s instructions and who take care of their braces will have the shortest treatment course. Remember, whether or not you decide to listen to your orthodontist will determine your treatment length!
