When children come for tooth extraction due to tooth replacement, they are usually not properly educated or intimidated by their parents. Most of the children are psychologically nervous and fearful of going to the doctor. The doctor needs to divert the child’s attention in order to have a smooth consultation. 1.Communicate with the child, give him/her encouragement and praise, mobilize his/her subjective initiative, establish confidence and determination to overcome difficulties, and eliminate the fear. 2. For the first replacement tooth, try to wait until it is mature before extracting it, which is less painful. 3. To sterilize the tooth when pulling it out, you can directly use the pulling forceps to hold the cotton ball to sterilize the corresponding part, then the pulling forceps do not leave the mouth (put the cotton ball in the vestibule of the mouth or take it out with the other hand), directly hold the tooth, and tell the child to cough loudly while applying force to pull out the tooth. In this way, when the child feels it, the operation is completed and the child is pain-free. Discussion: 1. The first impression of a person is crucial. If the first tooth extraction will be painful, then it will be more difficult for him to eliminate his fear in the future. If the first tooth extraction is not painful, then when the child comes back later, the child eliminates his nervousness and fear and can easily cooperate with the surgery. 2. When the doctor holds the cotton ball with the forceps, the child often refuses to open his mouth, but after disinfection, when the doctor takes the extraction forceps, he refuses to open his mouth. Therefore, the above contradiction is solved by directly pulling the tooth without leaving the mouth after disinfecting the cotton ball by holding it with the extraction forceps. 3. Minor pain has a lot to do with attention, and if we divert the attention of the affected person, then the minor pain will not be felt. Therefore, if we ask the child to cough loudly when the tooth extraction will be applied, the child’s attention will be focused on the cough and there will be no pain. One child was very nervous when he first came in and refused to open his mouth all the time. I said, “Well, I will help you sterilize it with medicine and it won’t hurt anymore. Later, when I told him that it was finished, he laughed and said, “Liar, you said you would sterilize it and then you pulled my tooth. Haha, I’m not afraid anymore.”
