When a tooth is extracted, it is usually painless if the patient’s tooth growth is standardized, his or her mouth is healthy, and the anesthesia is effective. If the tooth growth is not standardized, the anesthesia effect is not satisfactory, etc., pain may be felt. 1. Usually, tooth extraction is a minor surgery. If the patient’s tooth growth is standardized and there is no oral inflammation, the surgery is not very difficult and usually takes a shorter time. If the surgical anesthesia is good, the patient may not feel any pain. 2. If the patient’s tooth growth is not standardized, or the extraction surgery is more complicated, such as the extraction of retained wisdom teeth, it is necessary to cut the gums, remove the alveolar bone, and so on, the surgery will have a certain degree of difficulty. If local anesthesia is chosen for the surgery or the anesthesia is not satisfactory, pain may be felt. Patients are advised to visit a regular dental hospital and have the surgery performed by a professional doctor. Different types of anesthesia can be chosen under the guidance of the doctor, depending on the location and size of the tooth and the specific growth of the tooth, in order to reduce the pain caused by tooth extraction.
