Have been to the dentist. The Alergist and everyone else. It started as part of my Lyme disease. The B12 helps some as long as I remember to take them. The gummies are on my desk so i do when I come into my office. NO I have not lost weight! I still eat as normal. I can't really think of what triggers it. Often times it feels like pepper in your mouth. I have also been usin Sysodine tooth paste and it helps. I brush not only my teeth but also my mouth and tougue.
You learn to live with it!
