Q: Does it hurt to have a tooth extracted? A: At present, dental analgesic technology is very mature, and as long as the anesthetic is injected successfully, the tooth extraction process is painless. For some individual teeth with apical or local chronic inflammation, individual patients may feel a mild local discomfort during the extraction process, but the degree is generally acceptable. Q: What are the post-operative reactions after tooth extraction? A: Common postoperative reactions are pain in the extraction socket, facial swelling, restricted mouth opening, pain in the throat, painful swallowing, fever, etc. Nowadays, there is a minimally invasive method of tooth extraction with microdynamic system, which reduces the postoperative reactions compared with traditional bone chisel splitting and debridement and large incision flap extraction. However, this is relative. Minimally invasive only reduces the degree of post-operative reaction, not equal to no reaction. Q: What about bleeding after tooth extraction? A: Bleeding is one of the very common complications after tooth extraction, and its causes are multifaceted. Each person’s clotting time will have individual differences, and the clotting time after tooth extraction varies from one tooth extraction to another. Some patients have clotted blood within a few hours after tooth extraction, while others still have red blood in the mouth for 2-3 days. If a large blood clot can be seen with the naked eye above the alveolar sockets and adjacent teeth after surgery, and accompanied by fresh active bleeding from the sockets, it is considered possible that the tooth is bleeding after extraction. If only the saliva is red and there is a bloody taste in the mouth, but no localized large blood clots in the extraction sockets are seen, it is generally normal. Even if there is bleeding, the patient does not need to worry about anxiety and can contact the treating doctor or go to the emergency dental department for treatment, which is a simple process. Q: How to eat and drink after tooth extraction? A: No matter how many teeth were extracted at the same time, you can eat liquid food, such as milk, porridge, etc., 2 hours after tooth extraction, but it should be warm and cool, not hot. After 48 hours after the operation, you can basically eat normally (rice, vegetables, etc.), but not too hard. There is no definition of “hairy food” in Western medicine, and fish, mutton and other commonly known as “hairy food” are allowed to be eaten. Q: How many teeth can be extracted at a time? A: It depends on the patient’s health condition. A: It is possible for a healthy young person to have four wisdom teeth extracted at one time, while elderly patients with poor health will be treated at the doctor’s discretion. Q: Can I exercise after tooth extraction? A: Don’t play strenuous sports (sprinting, playing ball, etc.) after tooth extraction, but sports of general nature are allowed. Q: Do I need stitches for tooth extraction? A: Not necessarily, it depends on the situation. If there are sutures to be removed in a week or so, the removal of sutures is usually painless and there is no need to worry excessively. Q: Do I need to take dental x-ray before tooth extraction? A: For some more complicated teeth, X-rays are routinely required before extraction, in order to better see the root morphology and analyze the resistance, which helps the surgical design. X-rays are necessary before extraction of mandibular blocked teeth in order to see the relationship between the roots of mandibular blocked teeth and the mandibular nerve, and also to exclude some jawbone lesions, so X-rays are necessary for extraction of mandibular blocked teeth. For other types of teeth, the doctor will treat them at his discretion.
