My dentist told me to see my dr about acid inmy saliva. She noticed tooth enamel was disappearing. Dr put me on Tecta pills. But I told him that since teenage years when I lay in bed in the morning, if my stomach growls it is followed by fizzing in the back of my throat. It doesn t hurt or sting but I can feel and hear it. He says 2 more months of Tecta and if it s not resolved a camera will be put down my esophagus. I just saw that there are lots of forums online that talk about this fizzing, but none give any answers
