Removable retainers are clear, thin, slightly flexible, and made of a plastic-like material. They fit the exact shape and placement of the teeth.
Not only are there removable retainers, but there are also fixed retainers. Both types of retainers hold teeth in their new positions after “active” orthodontic treatment is completed. This allows the newly formed bone to harden around the teeth. Wearing retainers as instructed is the key to maintaining the success of orthodontic treatment. Patients may be advised to wear retainers full-time for the first six months after “active” treatment ends, with subsequent wear time reduced to night-time only. When not in the mouth, removable retainers should be kept in the case provided by the orthodontist.
