How does Invisalign treatment work? | Everything you need to know

Reviewed by Dr. Olga Karnakova, DDS

Invisalign uses a prescribed series of clear, removable aligners to move teeth gradually. Treatment begins with an examination of your teeth, gums, and bite. The clinician determines whether aligners are appropriate or whether another approach would better address your needs.

Planning your treatment

Records may include photographs, scans, and X-rays. Your clinician discusses the intended tooth movements and any preparatory dental care. Ask whether attachments, elastics, or other steps are part of the proposed plan.

Wearing and changing aligners

Follow the prescribed daily wear time and change schedule. Aligners are removed for eating and cleaning. Inconsistent wear can affect fit and progress. Contact the office if an aligner is lost, damaged, or no longer fits as expected.

Monitoring progress

Appointments allow the clinician to check tooth movement and oral health. Some plans require additional scans or aligners. Treatment length varies with the bite problem, planned movements, and how well the appliances are worn.

Daily care

Brush and clean between your teeth as directed. Follow instructions for cleaning the aligners and for what you can drink while wearing them. Tell the team about persistent discomfort or irritation rather than changing the appliances yourself.

Costs and retainers

Ask what the estimate includes: records, monitoring, additional aligners, replacement trays, and retainers. After active treatment, retainers help maintain tooth position. Your clinician provides a wear and follow-up schedule.
