The whole process of routine caries extraction is divided into local anesthesia, separation of the gums, quite loosening of the affected tooth, dental forceps extraction, scratching the extraction socket, cotton roll hemostasis. 1. Local anesthesia: If you need to extract the decayed teeth, you need to have local anesthesia before extraction, with local infiltration in the upper jaw and pterygomandibular block anesthesia in the lower jaw. 2. Separation of the gingiva: the gingival separator is used to separate the gingiva from the neck of the tooth to the top of the alveolar ridge. 3. Extraction of the tooth: first, use the dental tappet to loosen the affected tooth, then use the dental pliers to slowly force the tooth out. 4. Scratching to stop bleeding: Scratch the extraction socket with a spatula to remove the granulation tissue at the root tip and debris from the extracted tooth, and then apply pressure with a cotton roll to stop bleeding for 30 minutes. It is recommended to go to the hospital to check whether the caries can be retained before considering extraction.
