It's the first question almost everyone asks. The honest answer: it depends on how much your teeth need to move and how consistently you wear your aligners. Many adult cases finish in about a year; simple touch-ups can take only a few months, and complex bites take longer. Here's what shapes your timeline.
What decides your timeline
- How much movement is needed. Closing a small gap or fixing mild crowding is quicker than correcting a deep bite or significant crowding.
- Your bite. Changing how upper and lower teeth meet usually adds time.
- Wear time. Aligners only work while they're in. Invisalign recommends 20 to 22 hours a day.
- Refinements. Some cases need a short extra series of aligners at the end to perfect the details.
What the journey looks like
- Consultation and 3D scan. We scan your teeth with our iTero scanner (no messy impressions) and show you a digital preview of your planned result.
- Your first aligners. We check the fit and show you how to wear and care for them. Small tooth-colored attachments may be added to help certain teeth move.
- Switching trays. You move to a new set every one to two weeks. Each set may feel snug for a day or two; that pressure means they're working.
- Progress checks. Short visits every several weeks let us confirm everything is on track.
- Retainers. When your teeth reach their new positions, a retainer keeps them there. This step protects your investment for years.
Five ways to finish on time
- Wear your aligners 20 to 22 hours a day, and take them out only to eat, drink anything other than water, and brush.
- Put them back right after meals. Set a phone reminder if that helps.
- Switch trays on schedule, not early or late.
- Keep your aligner case with you so trays never end up in a napkin.
- Keep your progress appointments, so small issues are fixed before they add time.
