Black stuff on top of the teeth could be pigmentation or caries. Teeth are formed by the merging of several growth lobes during the developmental period, thus forming natural spots, gaps and grooves in the combined area, and these anatomical areas are relatively difficult to clean.

Examination can be found on the surface of the teeth is smooth, these do not require special treatment, the aesthetic requirements of patients can be sandblasted to remove.
2. Dental caries: It is mainly the collection of food residues in the points, gaps and grooves, and the invasion of bacteria, which leads to demineralization of the teeth and thus the formation of caries. During examination, it can be found that the surface is rough and the probe can be probed. It is necessary to remove the carious tissue and carry out filling treatment.
It is recommended to go to a regular hospital stomatology department, by the physician examination after a clear diagnosis, targeted treatment.
