After the lower wisdom teeth are extracted, it is recommended to remove the upper wisdom teeth. If the upper wisdom teeth do not bite after the lower wisdom teeth are extracted, they may gradually elongate, and the elongated wisdom teeth may cause discomfort in biting, and in serious cases, they may also affect the movement of the lower jaw, leading to disorders of the temporomandibular joint, which may easily lead to food embedding in the gap between the upper wisdom teeth and the front teeth, causing dental blockage, or the elongated Wisdom teeth are traumatic to the buccal mucosa. Therefore, it is recommended that after the wisdom teeth below are removed, the wisdom teeth above should also be removed together. The wisdom teeth themselves are not relatively helpful for chewing function, and after the wisdom teeth below are removed, the wisdom teeth above are even less useful and can be removed.
