A dental applicance worn for
2 - 6 years glued onto your
teeth by an orthodontist. Usually associated with more annoying or painful appliances, such as elastics, retainers, etc. You can't eat your favorite foods, they
cut your mouth after a while, and hurt when tightened. They are overpriced, and the only advantage is that your teeth are straighter... Until you
stop wearing the retainer they give you, which makes you have not straight teeth anymore >:(
