The jagged appearance of teeth after tooth replacement in children is normal in the vast majority of cases and is a physiological manifestation. Most of this manifestation is in children who are in pre-replacement, that is, 6-8 years old, and the upper and lower incisors have this problem at the incisive end, which we call the incisive margin nodules, which is a normal developmental manifestation and itself will show the W pattern on the teeth, indicating that the incisive ends of the upper and lower front incisors are developed from 3 developmental lobes. If you don’t think it’s very good to understand, you can imagine it as the pattern of a newly bought tire. At the beginning, when you buy a new car or a new tire, there will be a very new pattern on it, and later on, as time goes by, the pattern will gradually reduce, so will the newly erupted teeth, and in the future, as the child chews food, this jaggedness will gradually disappear right away.
