Quite few things...: This can be caused by a variety of inflammatory conditions in the mouth-- periodontal disease, infected teeth, mucous membrane disorders, and yeast infection. Upper respiratory catarrhal conditions and gastroesophageal reflux disease are also common offenders. Endocrine and metabolic disease can cause this, some medications-e.g. Metronidazole, and neurological smell/taste derangement (dysgeusia).

Many other causes: Bleeding or inflamed gums will cause a metallic taste. Vitamin deficiencies, prescription meds, leaking metallic fillings or crowns may also cause this. Rule out dental causes first, then see your doctor to rule out other possibilities.
