Wisdom teeth are wisdom teeth, not all wisdom teeth must be extracted, whether to extract depends on the growth of wisdom teeth and the obstruction situation. If the wisdom tooth has a normal chewing function, does not damage the neighboring teeth, does not decay, and does not cause swelling or pain, it is usually not necessary to remove it. If the wisdom tooth has frequent pericoronitis during eruption, or if the wisdom tooth is delayed to erupt smoothly, it can be considered to be extracted. Wisdom teeth with gingival obstruction, bone obstruction or obstruction of adjacent teeth also need to be extracted. Because obstructed wisdom teeth often cannot establish a normal occlusal relationship with the teeth of the opposite jaw, it can cause symptoms such as popping of the temporomandibular joint, painful mouth opening and night grinding for a long time. It is necessary to pay attention to maintain oral hygiene to avoid tooth decay. For patients who need to have their wisdom teeth extracted, wisdom teeth are generally more difficult to extract, and the extraction is more traumatic, and anti-inflammatory drugs can be taken prophylactically after the extraction to avoid infection. For patients whose wisdom teeth are more smoothly extracted and the extraction trauma is not too big, you can skip the anti-inflammatory drugs and pay attention to oral hygiene after the operation to prevent infection.
