There are two cases of black gaps in the middle of the teeth. One is that there are gaps in the middle of the teeth caused by dental calculus on the edge of the gums. The black gaps feel like black triangles. Once the dental calculus is removed, a black triangle of the gums will be formed. The gingival atrophy is caused. If this situation occurs, it is recommended to do crown repair or veneer repair to improve it, If you do not want to do veneer repair, the whole mouth is generally more, and the gums have shrunk, which is obvious. It is recommended to turn the flap from the jaw side of the upper jaw, and then take out the connective tissue flap. You can transplant and supplement the gums, but you must improve the method of brushing teeth. Otherwise, even if the operation is performed, it will shrink again in a few years, causing a rebound. Therefore, there are black gaps in the middle of the gums, and most of them form black triangles. It is recommended that veneer or crown repair be used to improve.
