Teeth are an essential “weapon” for us to enjoy delicious food, but there are many people who suffer from various dental diseases from time to time. Clinically, we often encounter patients with inflammation around a tooth, which needs to be extracted as the cause of the tooth, but due to the infection, they are reluctant to extract it or the doctor does not give it, and some even delay it for months, which is painful and leaves serious sequelae that endanger life. So, how to treat this kind of inflammatory area of the focal tooth? In fact, the best treatment is undoubtedly to actively control the inflammation, which means that the focal tooth should be extracted as soon as possible in an appropriate way to remove the diseased tissue to eliminate the source of infection, reduce tissue damage, protect healthy tissue and promote its recovery. Usually, the decision to extract a focal tooth during the acute inflammatory phase should be based on the patient’s general condition (e.g., presence of sepsis), ease of surgery (size of trauma), and other factors. If the patient’s systemic condition is poor or the surgery is complicated or damaged, extraction may aggravate or spread the inflammation and should be postponed. On the contrary, if the patient’s general condition is good and the surgical damage is small, extraction of the focal tooth under the effective control of antibacterial drugs at this time is conducive to drainage of the abscess, so that the severe pain can be rapidly relieved and the inflammation can be controlled and rapidly improved or cured. Generally speaking, the diseased tooth itself is the focus of infection, the source of inflammation, and the culture base of bacteria. Through the infiltration of inflammatory cells, it will cause local capillary congestion and increase the pain. If the opportunity of treatment is seized, anesthesia and surgical methods are improved, the focal tooth that can no longer be saved is extracted in a timely manner, and local tissue pressure and toxic reactions are reduced, this will help to limit the inflammation and can shorten the course of the disease and reduce the occurrence of complications. If the stage of development of inflammation is overly considered, and it is considered painful and inappropriate to extract teeth during the acute inflammatory period, the inflammation will continue to develop, destroying the surrounding tissues, forming fistulas in the oral cavity and skin, and even forming diffuse osteomyelitis and sepsis, which will delay the disease and even endanger life. At the same time, even if a large number of sensitive antibacterial drugs are used, the acute inflammation can only be controlled and made chronic because the lesion has not gone. As soon as the resistance is lowered, the infection will flare up acutely again. In this way, one way or another, drug damage to the liver and kidneys is produced, or due to long-term chronic irritation, some even end up with gum cancer at the age of about 50.
