As I was reading thru the most recent issue of ITG Journal I saw an ad by dentist John J. Kelly. The ad states "To play the highest notes, with the fullest sound, the design of your mouth has to be mechanically correct. Dr. John Kelly can redesign your mouth to fit naturally with your trumpet and the rest of your face. Using tecniques known to less than 1% of dentists, Dr. can improve your embouchure and range " When reading this at first the "hairs on my arms stood straight". After recovering from the ad, I went on to visit his web site at www.johnjkellydds.com I found it quite interesting all the tests he has available to test jaw positions, muscles etc. I have known people who have done dental work to enhance their teeth cosmetically(Filling in a gap similar to Jon Faddis's) and it was detrimental to their trumpet playing. I have never known of anyone who has done dental work to improve their playing. Any TM members have any interesting stories or experiences related to this topic?
