Yes, thank you. I had a large molar on the upper left side of my mouth removed last summer. The endodontist couldn't find anything unusual from the x-ray. He initially ordered a root canal, but the pain continued. Later, I had the tooth extracted. Since then, (six months ago), I have had a constant acidic taste in my mouth where the molar was. It seems to come from the site of the pulled tooth (#14). The acid flows around my mouth, is often thick (like mucus) and is very uncomfortable and painful to the gum tissue. What would you suggest I do from here?
