The metallic taste in your mouth is not unusual, and not too serious, luckily. However, normally there are a few possible causes. First, medication. Commonly prescription drugs will cause this taste, but it is better to be on the drugs than not have the taste, so I do not recommend getting off the drugs to alleviate the taste. The second, and more probably cause, has to do with your oral hygiene. The reason I say this is b/c this can cause metallic taste as well as pain in the mouth. What I am referring to is gingivitis, periodontitis, or tooth infections. All of these have to do with the level of bacteria in your mouth, which creates the metallic taste. As the bacteria damage your gums or teeth, it will cause an overall ache in your mouth. The best treatment is a scaling and root planing procedure to remove the bacteria, followed by a prescription rinse of chlorhexidine to kill off the bacteria for home care. You should visit a periodontist, who is a specialist that treats infections like this. They are more specialized than your dentist and know more about the disease and treatment. Until you do this, there probably is no over the counter medicine that will help.

You are welcome.
