Do I need to wear a retainer after clear aligner treatment
Yes, a retainer is essential after completing clear aligner therapy. Newly straightened teeth are still susceptible to shifting, especially after prolonged alignment. Retainers keep your smile locked into place long-term.
Clear aligner patients usually receive one of two retainer types:
Removable retainer – A clear plastic tray worn nightly as your last aligner set. They maintain your new position.
Fixed/Bonded retainer – A thin wire permanently bonded behind your front 6 lower teeth. It keeps these most prone to shifting teeth stabilized. You’ll also wear a removable retainer for the rest of your mouth.
What are the advantages of clear aligners over traditional braces?
Retainer use is key the first 6 months when teeth are still adjusting to their realigned positions. Afterward, nightly wear for at least 1-3 years is recommended, then periodically for life. Retainers are lifelong insurance to preserve your bright new smile!
