A. Black tooth stain is a characteristic extrinsic discoloration, which occurs along the third cervical line of the buccal and/or lingual surfaces of teeth, particularly in the primary dentition. However, the permanent teeth may be also concerned. They appear early on the tooth enamel, at the age of 2 or 3.
