Retention is a vital part of your treatment. You must keep your teeth in their new position with retainers.
If retainers are not worn as instructed, teeth can drift very quickly to their old position (this is called relapse).
All your hard work and that of the Orthodontist will go to waste. The type of retainer you are provided with will depend on your original situation, and so the Orthodontist will decide which is best for you.
A fixed retainer is fixed to the inside of your teeth and can stay in place for many years. Often referred to as a “bonded retainer”. Bonded retainers are much more difficult to keep clean. It is important when brushing that you ensure you brush the inside of your lower teeth as well as the wire.
