Invisalign treatment typically takes between 3 months to 2 years to work, depending on the complexity of the dental issues being addressed. For minor corrections like slight crowding or small gaps, noticeable results can appear within a few weeks and treatment might take around 6 months. More complex cases, such as significant bite problems or severe crowding, can extend treatment to 12-18 months or even up to 2 years. Patients are usually advised to wear the aligners for 20-22 hours a day, switching to new aligners every 1-2 weeks to ensure steady progress. Younger patients may see faster results due to more easily movable teeth. Consistent and correct use of the aligners significantly influences how quickly Invisalign works.
