Dental Retainer

Dental retainer helps prevent teeth relapse after orthodontic treatment and is of two types, namely temporary and permanent. Temporary retainers include Hawleys and clear plastic retainers, and these can be easily removed, cleaned, and placed back by the patient itself. Permanent retainers consist of a braided wire cemented to the lingual or palatal aspect of the front tooth.
