These retainers include a small metal wire, custom-designed to fit behind the teeth. They’re generally bonded to the back surface of the bottom teeth, but can also be used behind the top teeth depending on your condition.
Typically, this wire stays in place forever to hold your bottom teeth in their beautiful alignment. The only exception is if your family dentist determines that your oral hygiene is suffering, which could lead to bone or gum problems. Keeping your teeth clean with a permanent retainer is essential!
