What does it mean if I have a metallic taste in your mouth?

Not metal. Medications such as some antibiotics, prenatal vitamins and antidepressants, as well as drugs used to treat high blood pressure, rheumatoid arthritis and kidney stones and iodine can cause metalic taste. Oral problems, including oral infections such as gingivitis or periodontitis, tooth infections, and poor oral hygiene. Rigorous oral hygiene should be the first approach to treatment.
