What does it mean if you get a metallic taste in your mouth? what kind of metal would it be?

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.

Altered Nerves: Unless you are actually chewing on metal, your nerves or taste buds have been altered by something. This could be, but is not limited to the following: dry mouth, medication, toothpaste, mouthwash, bacterial or infection, autoimmune problems, or other health problems. If you are trying a new toothpaste or medication (consult your doctor first) i would consider changing it.
