Wisdom teeth grow positively and do not need to be extracted if there is an eruption of the opposite jaw wisdom teeth and there is a normal occlusal relationship; if the opposite jaw wisdom teeth are not erupted or blocked and there is no normal occlusal relationship, then they need to be extracted. 1. No need to remove: Wisdom teeth are the third permanent molars of human beings, which start to erupt at the age of 18. Some people have wisdom teeth, some do not have wisdom teeth, and some have blocked wisdom teeth. If the wisdom teeth are in the right place and there is an eruption of the wisdom teeth in the opposite jaw, which creates a normal occlusal relationship, they do not need to be removed. 2. Need to be removed: wisdom teeth grow very positive, but the opposite jaw wisdom teeth did not erupt or eruption position is not correct, can not produce a normal occlusal relationship, the wisdom teeth still need to be removed. If you have wisdom teeth, you should pay attention to oral hygiene, consult the dentist in time if you have any discomfort, complete the examination, and then the dentist will suggest whether the wisdom teeth should be extracted or not according to the specific situation of wisdom teeth eruption.
