Peng Shuai, one of the four “golden flowers” of Chinese tennis, came to Guangzhou last weekend to participate in the 2009 Guangzhou Open. The bright and cheerful Hunan girl revealed that she suffered from “wisdom teeth” during the US Open and had to stop in Hong Kong after the tournament to have them removed before she was able to fly around the Guangzhou Open like a swallow. Many young people between the ages of 18 and 25 are often “provoked” by “wisdom teeth” in their mouths like Peng Shuai, and this pain is not life-threatening, but it makes them “unhappy” both at work and in life. “and easy to poor oral hygiene, resistance to decline in the wisdom of peri-coronitis, when serious can lead to “dental closure” to affect the eating, chewing and swallowing. Wisdom teeth “use in and out” need to be decided early “to stay”. Wisdom teeth are commonly known as “wisdom teeth”, “net heel teeth”, and are the teeth closest to the throat. Wisdom teeth generally erupt around the age of 18, when the physical and psychological development of people are close to maturity, so it is seen as a symbol of the “arrival of wisdom”, so it is called “wisdom teeth” – wisdom teeth. The tooth of wisdom. The wisdom tooth is also a good example of the biological evolution theory of “using in and out”. As humans evolved, food became more refined and the jawbone became underdeveloped, the wisdom tooth, the last tooth to erupt in a person’s life, lacked sufficient space to accommodate it, often resulting in malposition and failure to grow properly, known medically as “blocked teeth. “However, not every wisdom tooth needs to be extracted”, Zhou Miao suggested that the “retention” of wisdom teeth should be evaluated early, for normal eruption and chewing function of wisdom teeth, can be retained and protected; while the wisdom teeth in the wrong position, usually do not have These teeth can easily bite the buccal mucosa or the gums of the opposite jaw, inducing pericoronitis or dental caries, and need to be extracted as soon as possible. Wisdom tooth pericoronitis can affect eating. The soft tissue (commonly known as “flesh”) covering the surface of wisdom teeth can easily become infected and lead to pericoronitis. Pericoronitis is most common in young people between the ages of 18 and 25 and occurs when oral hygiene is poorly maintained, when there is excessive trauma to the local flesh, and when the body’s resistance is reduced due to overwork. Peng Shuai had a pericoronitis attack on her wisdom teeth during her US Open match due to overexertion. Pericoronitis of the wisdom tooth occurs mostly in the lower jaw and is rare in the upper jaw. Pericoronitis is often acute, and in its early stages, the affected side of the parapharyngeal soft tissue is distended and painful, and the pain increases when eating, chewing, swallowing, and opening activities. If the disease continues to develop, swelling of the affected cheek may occur, and localized spontaneous throbbing pain or reflex pain in the auriculotemporal region may appear. As the inflammation continues to progress, there can be varying degrees of mouth opening restriction and even “clenching of the teeth”, resulting in the inability to eat, chew and swallow. “In the case of uncontrolled pericoronitis, the inflammation can also spread or spread, causing infection of adjacent tissues and serious complications, which is not uncommon in clinical practice.” To avoid this, Zhou Miao recommends “early detection and early treatment” of malpositioned wisdom teeth to avoid wisdom teeth pericoronitis bring more inconvenience to work and life. When wisdom tooth pericoronitis appears, you should go to the hospital stomatology department in time, and after the inflammation is relieved by treatment, the affected tooth should be extracted as soon as possible. Wisdom tooth extraction precautions. Before tooth extraction, the following points should be excluded: patients with large organ diseases such as heart, liver, spleen, lung and kidney should not be extracted; patients with acute inflammation in the extraction area should be suspended; patients with immune system and blood system diseases should not be extracted; pregnant women and menstruating women should be suspended. Self-care should be learned after tooth extraction: bite cotton balls for 30-50 minutes; do not chew on the side of the extracted tooth for 24 hours, and it is better not to brush or rinse the mouth on the same day; do not lick or suck the extracted wound to avoid affecting the healing of the wound; seek medical consultation when bleeding or severe pain persists after tooth extraction; it is normal to have blood in saliva within 24 hours; take anti-inflammatory and pain-relieving drugs after tooth extraction to prevent infection and pain of the extracted wound. Within 24 hours after tooth extraction, cold water towel can be applied to the cheek on the side of tooth extraction to stop the bleeding; 24-72 hours after tooth extraction, hot towel can be applied to the cheek on the side of tooth extraction to facilitate the swelling of the cheek on the side of tooth extraction. Tips . In what cases should “wisdom teeth” be extracted? In addition to the wisdom teeth that repeatedly cause pericoronitis like Peng Shuai, the wisdom teeth in the following cases also need to be extracted: 1. wisdom teeth with insufficient space for eruption, improper position, caries or caries of the neighboring teeth in front; 2. wisdom teeth that have no chewing function or cause food embedment and cannot be cleaned; 3. wisdom teeth that may be the cause of temporomandibular joint disorder syndrome (TMJ pain and popping); 4. wisdom teeth that are forcibly erupted. 4. Wisdom teeth that forcefully erupt and squeeze the teeth in front, resulting in the resorption of the roots or alveolar bone of the teeth in front; 5. When orthodontic treatment is needed to ensure the efficacy of orthodontic treatment; 6. Young women who plan to get pregnant can consider removing the blocked wisdom teeth before pregnancy to avoid the occurrence of pericoronitis during pregnancy. When pericoronitis occurs during pregnancy, it is much more difficult to deal with than usual; 7. When you need to travel or study abroad for a long time and the local medical conditions are not good, you can consider extracting the blocked wisdom teeth in advance; 8. Patients whose wisdom teeth are completely buried in the jawbone and are suspected of some unexplained neuralgia, or patients who are suspected of having focal teeth, should also be extracted.
