Wisdom teeth that are crooked usually need to be extracted if they are causing pericoronitis, affecting neighboring teeth, etc. Wisdom teeth grow crooked in most cases because there is not enough space for them to erupt. If they cause pericoronitis or affect the neighboring teeth, they usually need to be extracted. 1. Wisdom teeth are not fully erupted, the surface of the wisdom tooth covers the gingival flap, and food residues are retained under the gingival flap, which will cause pericoronitis of the wisdom tooth, and it is usually recommended to remove the wisdom tooth after the acute period. 2. Wisdom teeth and neighboring teeth between the food blockage, may make the neighboring teeth caries, or wisdom teeth compression of the roots of the neighboring teeth, resorption, also need to be removed. It is recommended to go to the hospital in time for treatment or therapy under the doctor’s guidance.
