lateral gingival dentition

1. Supernumerary teeth

refer to extra teeth beyond normal dentition, which may be related to genetic factors and abnormal development of tooth germ. Supernumerary teeth may lead to crowding and dislocation of normal dentition, affecting oral beauty and masticatory function. If supernumerary teeth are found, they should be treated promptly to evaluate whether they need to be extracted.

2. Ectopic eruption of permanent teeth

refers to permanent teeth deviating from normal eruption path during eruption, appearing in abnormal positions such as outer gingiva. This may be caused by retention of deciduous teeth, narrowing of dental arch, abnormal development of jaw bone, etc. Orthodontic treatment or other intervention measures are needed according to specific conditions to guide permanent teeth to correctly erupt into dentition.
