What are Retainers and why are they so important? A retainer is a custom-made orthodontic device composed of clear plastic and metal wires. Retainers are designed to hold teeth in position after a patient has received orthodontic care such as braces. Retainers can also work after surgery has taken place to hold individual teeth in their location.
Types. 1  Traditional metal wired braces are stainless-steel and are sometimes used in combination with titanium. Traditional metal braces are the most common type of braces. These braces have a metal bracket with elastic (rubber band) ties holding the wire onto the metal brackets. The second-most common type of braces are self-ligating braces that do not require elastic ties. Instead, the wire goes through the bracket. Often with this type of braces, treatment time is reduced, there is less pain on the teeth, and fewer adjustments are required than with traditional braces.
