A week ago, I pulled a wisdom tooth for a friend, because the wisdom tooth had grown crooked and damaged the front tooth, causing pulpitis in the front tooth, which caused pain for a long time. After the extraction, he said he didn’t expect it to be done so quickly and he didn’t feel any pain. I asked him why he didn’t come to see it earlier. He said he knew that the tooth had to be pulled out a long time ago, but he was afraid of the pain, so he put it off as long as he could. He also said that when the doctor pulled his wisdom tooth, he also pulled the tooth in front of him because of the pain on the other side of his teeth for more than 30 years. He still clearly remembers the horrible feeling of pulling out the tooth, and also clearly remembers that the doctor hit him more than 50 times with a hammer, and the extraction took almost four hours. If he had known that tooth extraction is so fast and painless nowadays, he would have come here a long time ago. When it comes to tooth extraction, many people frown: fear of pain, fear of becoming stupid, fear of hurting the nerve, fear of food ingrowth. Even, they are afraid of seeing the dentist. In short, there will be N reasons to be afraid. Tooth extraction is actually not scary because people lack understanding of it, which causes all kinds of worries and misunderstandings. There will be a pulling sensation during the extraction process, but no pain will be felt because the doctor will administer anesthetic in advance for local anesthesia. If the patient is afraid of the pain at the moment of numbing the needle, the doctor can also drop some numbing medicine on the gums first, and then numb it again to easily achieve a “painless” tooth extraction! For ordinary teeth, the extraction process is usually quick, but for those teeth buried in the gums (such as wisdom teeth in the lower jaw), the extraction process is relatively complicated. Pain may occur after the anesthetic wears off after the operation, especially since the jawbone is relatively hard and the blood circulation is relatively poor, there is a greater chance of postoperative wound swelling and pain. However, the pain can be relieved by taking painkillers if necessary. The lower alveolar nerve is located in the jawbone and is very close to the root tip of the wisdom teeth in the lower jaw. Many people say that wisdom and memory can be affected by wisdom tooth extraction, is this true? Wisdom teeth are teeth that grow slowly at the age of 18, when a person’s physical development is basically complete and his or her intelligence is becoming more mature, so they are called wisdom teeth, also known as wisdom teeth. In other words, wisdom teeth have no connection with human intelligence and memory. Memory is related to the brain, and a person’s intelligence depends on the function of the central nervous system, mainly the cerebral cortex. The inferior alveolar nerve is only a peripheral nerve, and the inferior alveolar nerve is a branch of the mandibular nerve. Even if the inferior alveolar nerve is injured, it will not have any effect on the intelligence of the brain, and as for the severed pulpal nerve, it is “several generations” away from the brain nerve. Therefore, it is completely unreasonable that wisdom tooth extraction will make you stupid. After extraction, there is usually a nest, during which there may be temporary food impaction. However, once the bone and flesh have grown in (a process that takes about 3 months), there will be no more food impaction. In addition, the new flesh and bone are growing from the bottom to the top, so it is not possible for the embedded food to be encapsulated in them, so there is no need to worry about this. After some people have their wisdom teeth in the lower jaw extracted, the socket against the lingual side is relatively sharp and may pierce the gums. Experienced surgeons will contour the socket in time during the operation to reduce unnecessary pain. Due to the refinement of food, wisdom teeth are no longer of great significance to the human chewing function. Functionally speaking, the third molar is a redundant tooth and 28 teeth can already meet the needs of modern people. Moreover, due to the late eruption of wisdom teeth, there is often not enough space for them, and few of them grow well, either not growing out or growing incorrectly. If they do not grow out, the gums will wrap around the wisdom teeth, causing inflammation of the gums and bad taste in the mouth. If the wisdom tooth does not grow out properly, it is likely to tilt and put the normal teeth against it, causing misalignment and even decay. For badly grown wisdom teeth, preventive extraction can be carried out.
