How long you will have to wear your Invisalign aligners will depend on how complex your orthodontic care is. For instance, those with greater misaligned teeth or bites may need to wear the aligners longer than someone who only needs minor straightening. However, on average, most Invisalign treatment plans last about 1 year. Your dentist should be able to discuss your treatment plan with you and give you an idea of how long you could expect to wear the aligners.
