Aligners

Clear aligners are a series of removable, transparent plastic trays that gradually shift teeth into a desired position, used as an alternative to traditional braces for mild to moderate orthodontic cases.

Clear aligners are typically worn 20–22 hours per day and changed every 1–2 weeks. Treatment usually takes 6–18 months. They are best suited to mild crowding, spacing, and mild bite issues.

For care tips during treatment, see our braces & aligner care guide. The Invisalign whitening system can also be used during alignment.
