Lateral teeth erupting first on top of the baby is an abnormal eruption sequence, but it is not necessarily a pathological manifestation. In this case, it is necessary to go to a specialized dentistry department and take a local dental film in this area if necessary to see if the incisors on the inner side of the lateral incisors will erupt immediately, and if it is found that the incisors themselves do not have any obstruction or pathology and will erupt immediately. Then we think that in this case there is only a local change in the sequence and it will not have much effect on the patient itself. However, in clinical practice, part of the reason for this situation is that the central incisors are obstructed in the median due to the presence of multiple teeth, which simply means that the multiple teeth are blocking the eruption of the central incisors. This condition is more common in clinical practice, and once this occurs, 1 must remove the buried supernumerary tooth as soon as possible. Then observe closely to see if the incisors can erupt normally, and if there is a problem, consider applying orthodontic treatment to pull them out.
