Maintain Teeth’s New Position:
A retainer is a custom-made, removable appliance that helps teeth maintain their new position after braces have been removed.
Retainers can also be used to treat minor orthodontic problems. The use of a retainer is a very important part of post-braces care. Retainers, which are typically made of rubber or clear plastic and metal wires that cover the outside surface of the teeth, need to be worn all the time for the first 6 months and then usually only during sleep.
The time frame for wearing a retainer will vary from patient to patient. The reason why a retainer is needed is that even though braces may have successfully straightened your teeth, they are not completely settled in their new position until the bones, gums, and muscles adapt to the change. Also, after long periods of time, teeth tend to shift.
