Hi. I ve had this problem before, but getting two crowns that I needed and a round of antibiotics made it go away. However, it is back and I have no dental issues. I just had a dental CT to rule out any dental issues. I have a discolored tongue (yellowish in color). I don t have bad breath, but my mouth is dry and water, in particular, tastes metalic to me. I don t like how it looks, and the metallic taste is recent (last few days), but the discolored tongue started a couple weeks ago.
Hellman of the problems of the mouth may be really irritating to the patient with no conclusion received from many examinations. There are many causes for bad taste as well as discoloration which can only be certain after a thorough examination and tests. Certain problems in other parts of the body may show symptoms in the mouth as well. So please visit a specialist in Oral Medicine to rule out the cause of your problem and to get prompt treatment. Hope you get well soon.
