Clear aligners: how they work and who they suit

Clear aligners are a series of thin, transparent trays made to fit your teeth precisely. Each set is shaped slightly differently from the last, so as you move through them your teeth are guided gently into a straighter position. Because they’re clear and removable, most people won’t notice you’re wearing them.

What can aligners fix?

• Crowded or overlapping teeth
• Gaps between teeth
• Mild to moderate bite problems
• Teeth that have shifted over time

Not every case is suitable for aligners — we’ll tell you honestly after an assessment.

How treatment works

1. Assessment and scan. We examine your teeth and gums and take a digital 3D scan — no messy moulds.
2. Your plan. We map how your teeth will move, stage by stage, and how many aligners you’ll need.
3. Wearing your aligners. Each set is worn for about one to two weeks, 20–22 hours a day.
4. Check-ups. We see you every six to eight weeks to check progress.
5. Retainers. When your teeth are in place, retainers keep them there.

How long does it take?

Mild cases can take a few months; more complex movements take longer, often around a year. Your plan will give you a realistic timeline before you start.

Getting the best result

• Wear your aligners 20–22 hours a day — time out of your mouth is time your teeth aren’t moving.
• Take them out to eat, and to drink anything other than water.
• Brush before putting them back in, and rinse the aligners every day.
• Wear your retainers as advised once treatment ends.
