Whether wisdom teeth need to be extracted depends on the specific situation and cannot be generalized. If the wisdom tooth erupts normally and can perform its normal chewing function without affecting the neighboring teeth, then it does not need to be removed. However, in some cases, wisdom teeth need to be extracted. Wisdom teeth that are obstructed and repeatedly cause pericoronal inflammation should be extracted; wisdom teeth that are obstructed, have their own decay, cause decay of the second molar, or cause food impaction for a long period of time need to be extracted; wisdom teeth that are obstructed in the near center cause crowding of the front teeth and need to be extracted to correct the teeth; wisdom teeth that are obstructed and may be the focal teeth of certain diseases need to be extracted. For these types of wisdom teeth, patients should have them extracted as early as possible, otherwise they may lead to pain, poorer bite, and even affect the surrounding healthy teeth. Patients can take dental films to clarify the direction, position and occlusal relationship of wisdom teeth and decide whether they need to be extracted based on the doctor’s recommendation.
