If the pain and other symptoms are not relieved, or if the chewing and eating functions of the teeth are seriously affected, you can go to the hospital for treatment as soon as possible, and if necessary, the teeth can be extracted directly; 2.periodontal inflammation: the cause of wisdom tooth pain is often related to the poor position of tooth eruption, which leads to the inflammation of periodontal tissues such as pulp and gum. The pain when the wisdom tooth is inflamed is relatively severe and may significantly affect the daily opening of the mouth and the function of the teeth bite. It is generally recommended that patients should undergo tooth extraction treatment after the inflammation has subsided. However, if the pain is more severe and not relieved by medication, tooth extraction can also be performed during the inflammation period; 3. Periodontal abscess: For patients with periapical abscess and gum abscess, direct tooth extraction may aggravate the injury site, so it is necessary to wait for the abscess to subside before tooth extraction; 4. Other: In addition, patients with inflammation of wisdom teeth are mostly accompanied by local bacterial infection, and it is possible to aggravate the surgical wound infection after tooth extraction The symptoms of wisdom tooth infection may be aggravated after tooth extraction. In severe cases, it may even lead to infectious reactions such as head and facial pain, swelling, and generalized fever, which may affect the wound healing, so direct extraction is not recommended for patients with infection symptoms.
