There is no strict time limit before the extraction of two wisdom teeth. If the wisdom teeth are extracted from the same side of the upper and lower jaw, it is completely possible to consider the extraction of the upper and lower jaw wisdom teeth together directly in one operation. The main reason why the interval between the extraction of two wisdom teeth is asked clinically is because both the left and right wisdom teeth need to be extracted. The main purpose is that after the teeth on the left side are removed first, the patient can use the right side for chewing activities, and after 2 weeks the left side is basically healed and the right side can be used for chewing activities after the right side is removed, which is simply the process of rotation.
