Wisdom teeth do not hurt and sometimes need to be extracted, if they affect the front teeth, as soon as possible. During the eruption of the wisdom tooth, pericoronitis or decay of the wisdom tooth itself can occur, causing pain in the tooth. Even if the wisdom tooth is not painful, it is necessary to decide whether the wisdom tooth should be extracted according to the specific situation. If there is enough space in the jawbone to accommodate the wisdom tooth during the eruption process and the wisdom tooth can be fully erupted, it can be removed without extraction. If the wisdom tooth does not have painful symptoms during eruption, but the wisdom tooth is blocked and causes compression and resorption of the front teeth or irreversible damage to the front teeth, it should be extracted as soon as possible. If the wisdom tooth decay has destroyed the apical area, and the inflammation spreads to the neighboring teeth or causes osteomyelitis in the jaw bone, it should be extracted as soon as possible. However, the tooth should be extracted only after the inflammation is completely controlled, otherwise it will cause the spread of inflammation throughout the body. If the wisdom tooth has fully erupted but there is no biting tooth in the opposite jaw, and the wisdom tooth elongates or bites into the mucous membrane of the opposite jaw and develops a traumatic ulcer, in this case, the wisdom tooth needs to be extracted even if it is not painful. Therefore, even if the wisdom tooth is not painful, there are times when it is necessary to remove it, such as when it causes compressive resorption of the front teeth, or when the inflammation spreads to the neighboring teeth, or when it elongates and develops traumatic ulcers.
