Your schedule is personalized
Some patients change aligners weekly, while others change them every two weeks or on a different schedule. Tooth movement, treatment goals, and how consistently aligners are worn all influence the plan.
✓
Wear time matters
Aligners are typically worn about 20 to 22 hours each day, removing them for eating, drinking anything other than water, and brushing. Wearing them as directed helps each aligner do its intended work.
✓
Do not rush ahead
Changing trays early without guidance can reduce predictability and make aligners fit poorly. If an aligner is not seating fully or is lost, contact your dentist for instructions.
