If there is sufficient space in the jaw bone, the eruption of wisdom teeth is completely normal and generally equivalent to the eruption of our normal teeth without any treatment, but clinically, because the volume of the jaw bone in most patients does not accommodate the eruption of wisdom teeth, the phenomenon of ectopic eruption is caused by the lack of space for the eruption of wisdom teeth. In this case, it is recommended to remove this wisdom tooth as soon as possible, because if it is not removed, this wisdom tooth may form a wisdom tooth pericoronitis, causing obvious inflammation and swelling around the wisdom tooth, and in serious cases, it may even cause decay of the second molar in front or even crowding of the whole mouth. Therefore, from this point of view, wisdom teeth that are completely normal in growth do not need to be treated, but if they erupt ectopically, they need to be extracted as soon as possible.
