Removable clear trays that move teeth gradually through a planned series of steps.
What it involves
Clear aligners are a series of plastic trays made from a digital plan. Each tray moves teeth a small amount. They are removable, which makes eating and cleaning easier, but they only work when worn for most of the day.
Who it suits
Suits mild to moderate crowding or spacing and people who will wear them consistently. Complex bite problems may need fixed braces. Gum disease and decay must be dealt with first.
How it usually works
Scans or impressions are taken, a digital plan shows the expected movement and the trays are made. You change trays at set intervals and attend reviews. Attachments, small tooth-coloured bumps, are sometimes used to help movement. Retainers follow.
Risks and things to consider
Results depend on wearing the trays. Teeth can feel sore after each change, and plans sometimes need refinement with extra trays. Online or remote-only plans without supervision carry added risk. Teeth can relapse if retainers are not worn.
Questions to ask before you decide
Who supervises the plan and the refinements? What happens if the teeth do not move as planned? What does the retainer plan cost and last?
