Jagged teeth can be improved with resin aesthetic restorations, veneers, and crown restorations, and anterior teeth with permanent teeth that erupt with jagged cut ends do not need to be improved. Jagged teeth are usually anterior teeth that have a jagged cut edge for some reason. If left untreated for a long period of time it can lead to splintering of the tooth. Resin aesthetic restorations, veneers, and crown restorations can solve this problem. Newly erupted front teeth cut off are also jagged and do not need to be treated. Resin aesthetic restoration is to prepare the jagged position, establish good retention, and improve it by resin filling. Since it is an anterior tooth, the resin filling needs to choose a color similar to the color of the tooth and restore the shape of the tooth, which is aesthetically very demanding. Veneer is a category of restorative dentistry, which requires preparation of the lip surface of the tooth, selection of the position of the shoulder table suitable for the patient’s condition, determination of the color of the veneer by means of colorimetry, and fixation of the veneer by means of bonding after the veneer has been fabricated. Crown restoration is the choice when the serration is too large and the veneer cannot meet the retention, crown restoration preparation of the tooth is more abrasive, not only can the crown be completely protected, but also can improve the aesthetic situation. After restoration in the above manner, it is necessary to avoid external mechanical stimulation, so as not to affect the service life of the restoration, but also to avoid the emergence of new serrations. The newly erupted anterior teeth cut off in a serrated shape is a normal anatomical form of the tooth and does not need to be treated.
