Finally, your braces have been removed and your smile is beautiful, straight, and best of all, metal-free! However, your orthodontic journey isn’t quite completed. To keep your smile looking its best, you’ll have to wear a retainer to preserve and stabilize your results. Retainers are needed to control or limit potential changes in tooth position. They are used after braces treatment to hold teeth in their correct alignment while the surrounding gums, bone, and muscle adjust to the new positioning of your teeth.
