A few weeks ago I had to have an upper bicuspid removed. Within a few days I noticed that my tone, endurance, and range, (such as it is), started to go downhill. Although a bicuspid is not one of the teeth directly behind the embouchure I'm wondering if the removal of this tooth could slightly change the alignment of the incisors and/or cuspid, (canine) teeth that would make a small change in the embouchure. I'm only asking this to try and determine what is going on. Is it the dental work or am I doing something stupid that is causing these problems? I should note that I also tinker around with an alto horn, and while my performance on that has been less than stellar lately, it has not gone as far down the tubes as the trumpet has.
