Four wisdom teeth should be seen in the hospital for a specialized oral examination. If the four wisdom teeth are orthodontic and there is no obstruction, and there is no soft tissue covering the tooth surface, no special treatment is needed. If there is any problem, we will see you in the hospital for treatment. If the four wisdom teeth are obstructed, and the wisdom teeth are proximally or distally, buccally or lingually oblique, with soft tissues covering the tooth surface, they should be extracted as soon as possible to prevent future problems. If not removed in time, it is likely to cause decay of adjacent teeth, pulpitis, alveolar bone resorption, and when the inflammation accumulates, it will cause pericoronitis of the wisdom tooth and lead to facial interstitial infection, causing great pain to the patient. Therefore, if the wisdom tooth is orthodontic and there is no obstruction, it can be observed with the clinic, and any problem lies in the hospital, if it is obstructed wisdom tooth, it should be extracted as soon as possible.
