Permanent retainers — also known as lower bonded retainers — use tiny wires to keep your teeth from shifting. These wires sit behind your teeth to hold your teeth in the proper place.
Lower bonded retainers can be a magnet for plaque build-up and require excellent oral hygiene habits. These generally are worn for two years after braces treatment. If kept clean during treatment and not causing dental problems, Dr. Lazzara may recommend keeping it in place indefinitely.
