Will retainers work after not using them for a while?

Retainers can still work after not being used for a while, but their effectiveness may vary based on how long they haven't been worn and individual dental changes. If teeth have shifted significantly, the retainer may not fit properly, and forcing it could cause discomfort or damage. It's advisable to consult an orthodontist before resuming use to assess fit and alignment. Regular wear is essential for maintaining teeth position, so it's best to use retainers as prescribed.
