Retainers help maintain tooth position after orthodontic treatment. Requirements vary, and teeth can move if retainers are not worn or no longer fit.
Retainers are used after braces or aligners to help maintain tooth position. Retention plans vary between people and orthodontic providers.
Retainers do not promise teeth will remain permanently unchanged. If a retainer breaks, is lost or no longer fits, seek advice promptly.
