Most people do not have a lot of extra room in their mouths. Your teeth, cheeks, palate and tongue take up most of the space in your mouth and allow you to enjoy a tasty meal and a good conversation. So what happens when you hook something to your tongue and try to function normally? According to researchers at University of Buffalo, as recently reported in the Journal of Clinical Orthodontics, there is a good chance your teeth will move. Tongue “studs” or “barbells” can exert force on the teeth and actually move them over time.
