Does some pressure on the tooth my fixed retainer is bonded to mean it is loose? if not how can tell if it is loose?

Visit a Dentist: IF there is pain associated with the pressure then it could indicate an abscessed tooth. An x-ray of the tooth will help the dentist determine what the tooth will need and also check to see if the tooth is loose.

Bonded retainer: considered the best way to prevent undesirable movement of the teeth. There is always the potential for the bonded retainers to come loose. See your orthodontist for evaluation.
