A permanent retainer is a dental appliance that is used to keep teeth in their correct position after orthodontic treatment. Permanent retainers are usually made of metal or plastic, and they are bonded to the back of the teeth. If a permanent retainer breaks, it is important to have it fixed as soon as possible to prevent the teeth from moving out of alignment.
Dentists can fix broken permanent retainers in a variety of ways. The most common method is to simply bond the broken pieces back together. In some cases, the dentist may need to replace the entire retainer. The cost of fixing a broken permanent retainer will vary depending on the severity of the damage.
