Amalgam Tattoo
Ever notice a small blue-gray "stain" in a soft part of your mouth after dental work? Called amalgam tattoos, they occur when a tiny piece of amalgam filling gets embedded in your cheek or gum. The silver in the amalgam leaches into your mouth's soft tissue, resulting in what looks a bit like a tiny tattoo. Amalgam tattoos pose no harm. But if the blue-gray spot grows or changes color, there is a good possibility it may not be an amalgam tattoo. Ask your dentist to check it out.
