Invisalign uses a series of clear, removable aligners to move teeth gradually. Here is how treatment usually works.
1. Assessment
Your dentist examines your teeth, gums and bite and takes X-rays, photos and a 3D scan. Not everyone is suitable for aligners, and some cases are referred to a specialist orthodontist.
2. Digital plan
The scan is used to plan the proposed tooth movements and the number of aligners. This plan is an estimate; it does not guarantee the final position of the teeth or the time it will take.
3. Wearing aligners
Each set is worn for about one to two weeks before moving to the next. Aligners need to be worn 20 to 22 hours a day and removed only to eat, drink anything other than water and clean your teeth. Small attachments may be bonded to some teeth.
4. Reviews and refinements
Regular check-ups track progress. Some people need extra refinement aligners.
5. Retainers
Teeth tend to move back after treatment, so retainers are needed long term.
Risks
These include discomfort, gum problems, decay if hygiene is poor, root shortening and relapse.
