I had my teeth completely removed and have had dentures for about 9 months. I played flute for nearly 30 years prior. Dentures are NO comparison to braces, a missing tooth, crowns, or implants!!! My daughter is going into grade 6 band in the fall and I thought I would start teaching her, but found when I picked up my flute that my fingers still worked like magic but that my mouth had an evil spell cast on it!! I can't even make a sound!! My problem is actually the top plate as it goes around the outside front of my gums causing less space there and more tightness of my lips therefore causing me to not be able to get an aumbouchure to blow with downward pressure into the mouthpiece. I am utterly devastated as playing flute has been my life!!! Will continue to try, but I am the first to say it will NEVER be even close to what it was. No more beautiful music for me!
