The child is full of tooth decay and starts to cry when it is mentioned to go to the hospital, and the mother and father have tried every possible way to achieve little result. Since we know the danger of tooth decay, treatment is imperative. For children who cannot cooperate at all, dentists used to take measures such as forcing treatment under bondage and punishing children in a small dark room, which not only have poor treatment effect, but also leave a deep psychological shadow to children and make the subsequent treatment more difficult. With the increasing maturity of pediatric anesthesia technology, it is being used more and more widely in pediatric dental treatment, providing a solution for children who cannot cooperate with treatment, have systemic diseases or are disabled. Regarding general anesthesia treatment, the most important questions parents are concerned about are: 1. Is it safe to fill teeth with general anesthesia? The current anesthesia technology is very mature, and the safety of the child can be guaranteed to the maximum extent, but the anesthesiologist will explain to the parents the risks and possible accidents of anesthesia, as well as pre and post-operative precautions. 2.Will general anesthesia affect the child’s intelligence? Current research shows that dental treatment under general anesthesia will not have any adverse effect on the child’s intelligence. 3.Can I keep more teeth with general anesthesia? The method of dental treatment under general anesthesia is the same as that of outpatient treatment. For the teeth with large destruction of dental tissues and serious destruction of root tip, the treatment effect will not be improved and preserved by general anesthesia. 4.What discomfort will there be after general anesthesia filling? Some children will be irritable and cry during anesthesia resuscitation, postoperative pain in the extraction wound, a little bleeding, sore throat, discomfort in biting, etc., which are normal phenomena and will gradually disappear after proper care and adaptation. 5.What problems need to be noted after general anesthesia? The number of extracted teeth is more fluid and semi-liquid diet for three days and soft food for one week, and the number of extracted teeth is less or no extracted teeth is less fluid diet on the day of surgery and soft food for one week after surgery. In addition, routine follow-up examinations are performed one week, one month, three months, six months, one year after surgery and every six months thereafter.
