you sed that your dentist said there was nothing wrong with your teeth or roots, which means that yuou are not going to lose ya teeth. it is phyhcological, that feeling of your teeth coming out is in your mind. it is the fear that you have, of losing ya teeth, that is making you feel this way.
if you dont want medical help then keep ya hands busy so that they cant fiddle with ya teeth. to keep my hands busy i paint, im not a good artist but it keeps me busy, while i can concentrate on it. let us know how you get on.
