Why Are My Gums Turning Black? A Guide to Dark Gums & Black Triangles
Looking in the mirror and noticing that your gums have changed colour can be a worrying experience. Whether it is a dark line underneath the gum tissue, a black spot that wasn't there before, or dark gaps appearing between your teeth, the visual change is often the first sign that prompts patients to call us.
The first step is to distinguish between a cosmetic concern and an active infection. If your dark gums are accompanied by severe pain, a metallic taste, or rapid tissue loss, this could be a sign of Acute Necrotising Ulcerative Gingivitis (ANUG). This is a serious condition requiring immediate attention.
