Jagged teeth can be treated by observation, resin filling, and crown restoration, and different treatment options are selected according to different clinical situations. There is no need to treat physiologic serrated teeth. This type of serrated tooth is usually a manifestation of normal molar replacement, newly erupted incisors, and is commonly seen on the incisal edges of newly erupted incisors, which appear to be distinctly serrated. This is mainly due to the development of the dentition from a number of growth lobes and the formation of a normal physiological structure, this serrated teeth will be erupted with the teeth to reach the surface, in the chewing movement, with the cut end of the constant friction with the food, and gradually wear down the serration into a neat shape. Clinically, there is another kind of serrated teeth, that is, melon teeth, commonly used in the application of the fixed part of the incisal end to eat hard objects similar to melon, this kind of teeth can be considered to apply resin filling, or direct crown restoration method, for this kind of melon teeth for treatment. Of course, this kind of melon teeth mainly affects the aesthetics, and the impact on the function is not very big.
