Something to get your teeth in. Advice required as a matter of urgency having played brass instruments for more years than I care to remember I am now in great difficulty trying to solve the predicament I find myself in. Over the years, I have lost teeth on a regular basis and I am now the owner with only the following teeth. Right Upper 1,2,and 3, Right Lower 1,2,3 and 4. Left Upper 1,2,3,4 and 5. Left lower 1,2,3 and 4. Due to this, it means that these remaining teeth have to bite and chew and over the years, they have worn away. This has been a gradual change and I have been able to manage playing my EE flat Bass with few problems. On my last visit to the dentist, it was found that my jaw was working in the wrong position and the remaining teeth had to be altered to realign my jaw. This meant that as a start the remaining teeth had to be lengthened permanently in order that the jaw would align itself to a new position. This was all thnat could be done for th first3 months prior to fitting implants, crowns, and bridges. The lengthening process meant that the upper and lower teeth were extended by 3/8 “ making my jaw ¾” wider. Due to this, it has altered the position of my mouth on the mouthpiece and there is no feeling on the teeth due to the extensions. I practice aprox. 2 hrs daily but I still cannot play notes below bottom C. High notes are no trouble at all except that all notes are now out of tune and this is not approved of by the rest of the Bass section. If I have to hold a single note for any length of time, my lips start to vibrate uncontrollably and the only way then is to stop playing and tongue the note again. Has this got something to do with embouchure? I have tried different mouthpieces to try to solve the problem but to no avail. My dentist informs me that the problem will cease when all the teeth are fitted but the new position of the jaw will remain. I hope that some readers will be able to throw some light on my situation and help me out over this difficult time. I could of course take the easy option out and join the percussion section, but that would not give me the same satisfaction as playing a brass instrument. Here is hoping for an answer to my problem, that no doubt has been solved by other people in the Brass Band world. T.M.P. has never let me down ion the past and solutions have always been found.
