Does tooth extraction have sequelae?

Tooth extraction is a common dental treatment technique in stomatology, and most tooth extraction operations are smooth with few sequelae. But there are also some patients, because of their own physical condition and local anatomical structure changes and abnormalities, or because of some shortcomings in the diagnosis and treatment process of doctors. The main possible sequelae are as follows: 1, syncope: caused by transient cerebral ischemia. Some patients have syncope after injection of anesthetic or during operation. The reason may be that patients are afraid of tooth extraction; Or preoperative fatigue, hunger, weakness, or the weather is too hot and the air is not fresh. 2, soft tissue injury: mostly due to improper operation by doctors during tooth extraction, resulting in gingival or soft tissue laceration. If the damage range is not large and serious, no special treatment is needed. If the damage range is too large and there is too much bleeding, it should be sutured. 3. Injury of adjacent teeth: due to improper placement of dental forceps, adjacent teeth are damaged when teeth are shaken. Or when using the tooth extractor, slide the teeth with the adjacent teeth as the fulcrum to loosen the adjacent teeth. 4. Root-cutting: There are roughly three reasons for root-cutting during tooth extraction: ① The tooth is too damaged and easily broken when it is pulled out; ② Abnormal bending of root anatomy; ② There was no looseness or improper force during tooth extraction. Rooting should be removed according to the specific situation. 5. Misentry into the esophagus or trachea during tooth extraction: When tooth extraction, the patient's mouth is open, especially for crying children. Once the tooth extraction instrument fails to clamp the extracted teeth well, the teeth will fall off, and the teeth will easily slide into the esophagus or trachea, causing great danger.
