A retainer is a simple device that helps to correct your bite, as well as sometimes address other conditions. You may have seen people wearing a retainer before, but they are not all that noticeable. A retainer is a small device that is made out of clear plastic, rubber, or even metal. They are custom-made so that they only fit your teeth. They are part of a treatment plan that has likely been determined by an orthodontist.
Retainers are an essential part of every Invisalign treatment. Without them, months and even years of dental work could go out the window with the teeth beginning to shift back to their original, incorrect position.
