Invisalign FAQs

Invisalign treatment time depends on your individual needs and the complexity of the tooth movements required. Some patients complete treatment within several months, while others may need 12–18 months or longer. Your dentist will provide an estimated timeline after evaluating your teeth and developing your treatment plan.

Significant, sharp, or persistent pain is not something you should ignore. Contact your dentist if you experience unusual discomfort or have concerns about how your aligners fit.
