In the dental surgery clinic, there are many patients with tooth extraction, but I am very strict about the indications, and I usually do not recommend extracting the teeth that can be done without extraction, and I recommend not extracting the teeth that can be done without extraction for the time being. The following are some of my cases of not extracting teeth: 1. not extracting if there is no indication for extraction, even if the patient strongly requests it 2. not extracting if there are obvious contraindications 3. not extracting if the patient refuses to sign the informed consent form for extraction 4. not extracting if the patient thinks that “toothache is not a disease, extraction is a trivial matter, extraction is risk-free, and the dentist is not a doctor” 5. not extracting if the patient is over 65 years old and is not accompanied by family members 6. Those who refuse to pay the medical fee and bargain with the doctor will not be extracted. 7. Inpatients who do not obtain the consent of the bedside doctor will not be extracted. 8. Those who refuse to take oral panoramic film for wisdom teeth will not be extracted. 9. Do not extract
