When an opposing teeth bite on the surfcae of operculum, it could start or induce pericoronitis causing a repeatition cycle of inflammation and trauma. [13] The opposing teeth which are over erupted will go to the space left by impacted teeth which could damage operculum and induce pericoronitis.
Teeth that can not erupt fully which is more common in the lower mandibular third molars are usually caused by limited space for eruption, or eruption in a non ideal angle of resulting in tooth impaction. The presence of supernumerary teeth (extra teeth) makes pericoronitis more likely.[8]
