Hello, Thanks for your query. Pigmented entities may arise from intrinsic and extrinsic sources. The color may range from light brown to blue-black. The color depends on the source of the pigment and the depth of the pigment from which the color is derived. Visit the dentist and get it examined. I do hope that you have found something helpful, and I will be glad to answer any further query. Take care
