Invisible braces can be worn for an average of six months. The severity of your needs for teeth straightening and your ability to follow your treatment plan will determine the length of treatment. Many invisible aligner brands say treatment will last between four and six months. Invisalign patients can expect to wear aligners for up to 18 months.
Because they are worn for a shorter amount of time per day, those who choose nighttime-only invisible braces may need longer treatment. People who choose to straighten their teeth at home and have fewer visits to the dentist may also require a longer treatment time. This is because the process is not as closely monitored than one that requires in-office visits. To avoid delays in the treatment, those who opt for at-home straightening should follow all instructions.
