At the mention of tooth extraction, many people frown: fear of pain, fear of becoming stupid, fear of injury to the nerve, fear of food impaction …… or even, fear of meeting the dentist …… In short, there will be N reasons to be afraid …… Tooth extraction is actually not scary, because people lack of understanding of it, which will cause all kinds of worries and misunderstandings. 1, tooth extraction is very painful? “There may be pain when the anesthetic subsides after the operation, and it can be relieved by taking painkillers if necessary.” The extraction process will have a pulling feeling, but will not feel the pain, because the doctor will play anesthetic in advance for local anesthesia. If the patient is afraid of anesthetic into the needle the moment of pain, the doctor can also drop some anesthetic on the gums, and then hit the anesthetic, easy to realize “painless” tooth extraction! For ordinary teeth, the extraction process is usually relatively fast, for those buried in the gums of the blocked teeth (such as wisdom teeth in the lower jaw), the extraction process is relatively complex. Post-operative pain may occur after the anesthetic wears off. Especially the jawbone is hard and blood circulation is relatively poor, there is a greater chance of swelling and pain in the wound after the operation. However, if necessary, take painkillers to relieve the pain. 2, tooth extraction will hurt the nerve of the tooth? “It is possible to injure the inferior alveolar nerve by extracting certain teeth, such as the wisdom teeth in the lower jaw, but usually this is only temporary and can return to normal after a period of time.” Take the lower teeth as an example, its pulp nerve comes from the inferior alveolar nerve, which is located in the jawbone, very close to the tip of the root of the mandibular wisdom teeth, extracting wisdom teeth, especially when extracting blocked teeth and buried teeth, may damage the inferior alveolar nerve, the symptoms mainly manifested in the same side of the mandibular skin sensation of numbness, but because the nerve has a strong self-repair function, usually will return to normal in a few months. 3, wisdom teeth extraction will become stupid? “Wisdom teeth extraction will lead to the pulp neurovascular fracture, but this and the brain nerves are two different things, and intelligence is even more hitched.” Many people say that wisdom teeth extraction affects one’s intelligence and memory, is this true? Wisdom teeth are teeth that slowly grow out at the age of 18, when a person’s physical development is basically complete and his or her intelligence is maturing, hence the name wisdom teeth, or wisdom teeth. In other words, wisdom teeth have nothing to do with a person’s intelligence or 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, the inferior alveolar nerve belongs to a branch of the mandibular nerve, even if the inferior alveolar nerve is injured, the brain’s intelligence will not have any effect, as for the severed pulpal nerve, but also and the brain nerve is different from the “several generations” it. Therefore, wisdom teeth extraction will become stupid is completely unreasonable. 4, easy to insert food after extraction? “There may be temporary food impaction, when the bone and flesh grow well, there will be no problem.” There is usually a nest after tooth extraction, during which temporary food impaction may occur. However, when the bone and tooth flesh grow back (a process that takes about 3 months), food impaction will no longer occur. In addition, the new flesh and bone grow from the bottom up, and it is unlikely that the embedded food will be encased in it, so there is no need to worry about this. Some people after the extraction of wisdom teeth in the lower jaw, against the tongue side of the groove is relatively sharp, may be pierced the gums, experienced doctors will be in the operation in a timely manner will be thwarted flat alveolar bone, to reduce unnecessary pain. 5.Do all wisdom teeth need to be extracted? “Poorly grown wisdom teeth can be extracted prophylactically.” 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. Wisdom teeth seldom grow well, either they don’t grow out or they don’t grow properly. If they don’t grow out, the gums will enclose the wisdom teeth, causing inflammation of the gums and bad taste in the mouth. If they do not grow out, the gums will enclose the wisdom teeth, causing inflammation of the gums and bad taste in the mouth. If they do not grow out, the gums will enclose the wisdom teeth, causing inflammation of the gums and bad taste in the mouth. Wisdom teeth that do not grow properly can be extracted prophylactically.
