Whether wisdom teeth should be extracted when they have not grown out and are wrapped in flesh is determined by examination, such as the direction of growth and the presence of wisdom teeth in the opposite jaw, before deciding whether or not to extract them. The patient can go to the stomatology department of the hospital, and through the radiographic examination of its surface tomography, find out whether the wisdom tooth will continue to grow, and also determine whether the direction and position of the wisdom tooth are correct after growth, whether there is wisdom tooth in the opposite jaw, and also determine whether it can produce a better occlusion with the wisdom tooth in the opposite jaw, and then based on the results of the examination, and then decide on the basis of the doctor’s advice to extract it or not. If after examination, it is found that the wisdom tooth no longer continues to grow and is in a bad direction and position to produce a good occlusion with the wisdom tooth in the opposite jaw, or there is no wisdom tooth in the opposite jaw, it is best to remove it in this case. If the situation is reversed, it can be considered not to remove it, and through the pericoronary gingivectomy, the crown of the wisdom tooth is partially exposed to help it to reach a good occlusion with the teeth in the opposite jaw. It is recommended to go to a dentist in a regular hospital for a checkup and listen to the advice of a professional doctor before deciding whether or not to remove the wisdom teeth.
