What is Clear Aligners?
Clear aligners are a series of custom-made, removable transparent trays. Each tray moves your teeth a little closer to the target position, and you progress through the series over time.
Why is it needed?
For suitable mild-to-moderate alignment issues, aligners offer a discreet, removable alternative to fixed braces.
Symptoms & signs
- Mild-to-moderate crowding or spacing
- A preference for a near-invisible option
- Wanting to remove the appliance for eating and cleaning
Common causes
- Inherited tooth positioning
- Minor relapse after previous orthodontics
The procedure, step by step
- Assessment & scan. The dentist checks suitability and takes a digital scan to plan tooth movement.
- Custom aligners. A series of trays is made to your treatment plan.
- Wearing the trays. You wear each set for the recommended hours per day and switch to the next set as directed.
- Retention. A retainer maintains the final result.

Periodic check-ups over several months to a year or more, depending on the case.
Recovery time
Mild pressure when starting a new tray is normal and eases within a day or two.
