Black stuff on the top of the teeth can be removed if it is stagnant plaque. Smaller spots can be polished using a polishing paste, and there is an option to use a grinding wheel to abrade and polish to be able to remove the black stains from the surface of the tooth. If the dark stains are large and there is calculus, it is recommended to use ultrasonic vibratory scaling to remove them. In the case of black stains in the fossa and pitting of the teeth, it is not possible to remove them completely because vertical vibration is not recommended during scaling to avoid fracture of the tooth. If this black color has been retained in the fossa of the tooth and a cavity has been created, in this case it is necessary to carry out a filling, using a dental drill to remove the black part of the corrosion, and then carry out a filling, the material used for the filling can be composite resin, which is conducive to the resistance of the tooth to fracture.
