Retainers are used after active orthodontic treatment is completed with braces. Your braces will be removed and retainers will be made which can be fixed or removable. This has to be worn for a minimum of one year.
During active orthodontic treatment with braces, teeth are moved within the bone and can sometimes feel loose during this time. When the alignment is complete, teeth are moved into a new position and has to be stabilized by new bone formation around the tooth. This is the period of retention. Failure to wear retainers will cause the teeth to move back to their original position.
Advantages
Retainers prevent teeth from shifting back to their original position.
Wearing a retainer can not only straighten teeth but they can improve breathing at night.
