The jagged shape of the teeth usually has two causes in the first place. On the one hand, it is an acquired wear factor, which is common in patients who eat hard objects, especially melons, and this patient will have a jagged shape in the fixed part of the incisors, which we usually call melon teeth. This condition is very common in clinical practice, and if the patient does not require a high degree of aesthetics, there is no need to treat this condition. In addition to this acquired wear and tear factor, there is also a congenital factor, which is divided into physiological and pathological factors. Physiological factors are common in children between 6 and 8 years old, when incisors begin to replace. At this time, the incisors that have just been replaced will have a distinct jagged appearance. This is mainly due to the development of the teeth, as the teeth have multiple growth lobes, the newly erupted teeth will have a more pronounced jagged appearance. This jaggedness will gradually flatten out as one chews, and there is no need to treat it. In addition to this condition, there is also the condition of congenital syphilis teeth, which is seen in patients with syphilis infection who develop a half-moon incisor, a condition similar to a jagged tooth, after the tooth has been replaced. In this case, there is no perfect treatment, but it is possible to consider the restoration of the tooth with a crown, or the direct extraction and restoration with an implant.
