Aligners: a step-by-step guide

1. AFTER a consultation, your orthodontist maps out your bespoke treatment plan.

2. HE OR she will take an imprint of your teeth to create a series of clear, removable retainers to wear over them.

3. EVERY few weeks, you swap one set of aligners for a new set. Each moves your teeth until, after six to 12 months, you have a straight, healthy smile.

4. YOU must keep your aligners on for 22 hours a day, only taking them out to eat, drink and brush your teeth.
