What could cause a metallic taste in my mouth, and how can I treat it?

I fully agree with Dr Lee that chewing on one side will do little to help with the problem. In my experience as an aesthetic physician, it is as Dr Lee said, most of us have mild asymmetries, and almost every case of asymmetry has a mixture of BOTH bony and muscular elements. If the asymmetry is bothering you, I would suggest some botox and fillers first to correct it as a temporary measure. I would refer to my dental or orthodontic colleagues to correct teeth alignment and jaw surgery for better functional outcomes and long-lasting results.

Thank you for your question. Oral fibromas are benign growths (consisting of scar tissue) in the mouth that usually appear following repeated trauma (usually from rubbing of your teeth or dentures/braces against the inner lining of your mouth or from accidental lip biting). The inner cheek area (buccal mucosa) would be most common.
