Wisdom teeth are actually a physiological phenomenon. It usually hurts. People normally have 32 teeth, but some modern people have only 28 teeth that have degenerated. Wisdom teeth are called “third molars” in medicine. They usually grow after the age of 18, which is the peak of human intelligence development. period, so it is also called “wisdom teeth”. With the evolution of human beings, the jaws gradually became smaller, but the size and number of teeth did not change accordingly. Therefore, the third molars that finally grew out were squeezed by the surrounding tissues because there was no room for growth, and the growth process was more painful. . In the initial stage of wisdom teeth eruption, go to the hospital to take X-rays to determine whether the growth position is correct. Once the position is found to be incorrect, remove it immediately. When should wisdom teeth be removed?
One is malposition, which is common in the mandibular wisdom teeth. For example, because the wisdom tooth grows forward and squeezes the adjacent tooth. In addition, rearward, lingual, buccal, or even downward growth can be harmful. The abnormal growth direction of wisdom teeth usually leads to gaps or grooves between the wisdom teeth and the adjacent molars. It is easy to incarcerate food residues. If it is not cleaned for a long time, the adjacent molars will develop caries, pulpitis, apical inflammation, etc. .
The second is pericoronitis. Due to incomplete eruption of most wisdom teeth, a part of the tooth crown is surrounded by the gums, forming a blind pocket, and food residues are easy to get in and out, resulting in red and swollen soft tissue around the coronal cavity, empyema in the blind pocket, pain, difficulty in opening, fever and other symptoms. Pericoronitis can recur repeatedly, and in severe cases, infection of the perimaxillary space and mandibular osteomyelitis may occur.
The third situation is that the wisdom tooth itself has caries, unless the position is normal and the occlusion is good, it is generally not retained. When growing wisdom teeth, pay attention to various minor symptoms, such as repeated swelling and pain at the site of wisdom teeth, even if the interval is very long, you should be aware of the possibility of pericoronitis. In addition, the total stuffing is also a signal. It may be because of the large gap between the teeth or the occurrence of caries. It is necessary to see a doctor as soon as possible, and do not wait until it is serious before seeing a doctor. References Medical common sense says that wisdom teeth are the teeth that start to grow in adulthood. Generally, there are 28 teeth that grow after the deciduous teeth fall out during childhood. Adults will grow 4 more, which becomes 32, which means that you grow up. adult. In medicine, wisdom teeth are also called third molars. They are the eighth teeth from front to back. Wisdom teeth are the last permanent teeth to grow out of the thirty-two permanent teeth in humans. They are located at the back of the upper, lower, left, and right dental arches. Wisdom teeth are also called wisdom teeth because they are usually around the age of sixteen to twenty-four when they grow. In the process of human evolution, as the food becomes more and more refined, the burden on the jawbone is correspondingly reduced, resulting in the continuous reduction of the jawbone bone mass, but the volume of the teeth does not decrease accordingly, and finally the position of the teeth to erupt is insufficient, and the last eruption of the first teeth. Trimolars are the most likely to form wisdom tooth pericoronitis, which is the main reason for the abnormal eruption position of wisdom teeth. The origin of wisdom teeth Wisdom teeth refer to the four third molars in the human oral cavity, the innermost, upper, lower, left and right sides of the alveolar bone. Because these 4 third molars began to erupt at the age of 20, when people’s physical and psychological development was close to maturity, so they were regarded as a symbol of “the arrival of wisdom”, so they were called “wisdom teeth” – wisdom teeth. In fact, from the point of view of modern medicine, wisdom teeth are inevitable in human evolution. As we all know, “use it and lose it” is a universal law in the theory of biological evolution. Wisdom teeth are an excellent example. Wisdom teeth, scientific name of the third largest molars, commonly known as wisdom teeth, standing teeth, end teeth, are the teeth closest to the throat, if all grow out, a total of 4, two on each upper and lower jaw, usually grow at the age of 16 or later come out. In contrast to milk teeth that grow in infancy and permanent teeth that are replaced in childhood, wisdom teeth usually appear when the human mind has matured, hence the name. In terms of the growth of wisdom teeth, there are great individual differences. Some people grow before the age of 20, some people only grow in their 40s and 50s, and some people do not grow in their entire lives. This is normal. Moreover, all four wisdom teeth are not necessarily full. Some people may only have 1 to 2 wisdom teeth, and some wisdom teeth may not grow even half way. This is called impacted wisdom teeth. The position of the wisdom teeth starts from the gap between the front teeth, and counts the number of teeth from the front teeth on one side. If there is an eighth tooth, it is a wisdom tooth. How do wisdom teeth grow?
During late adolescence, the jaw bone develops to near adult size. But some people’s jaws aren’t big enough to have enough space for their wisdom teeth to erupt. Wisdom teeth are impacted in the jawbone and grow in other directions. There may be only part of the crown exposed to the gums, or it may be completely buried in the jawbone. The root of the tooth may deform or grow into the upper sinus or where the mandibular nerve is located, which is dangerous. Direction of Wisdom Teeth Growth Due to lack of space, impacted wisdom teeth grow in various directions, generally at an angle to adjacent teeth. It can grow toward adjacent teeth (mesial angular impaction), away from adjacent teeth (distal angular impaction), or horizontally or vertically. Diseases caused by wisdom teeth: Due to the special position of wisdom teeth growth, it brings many problems to its cleaning and treatment. The diseases often caused are dental caries (commonly known as tooth decay), periodontitis, and pulpitis. Because the wisdom teeth are in the innermost position, daily brushing is not easy to clean, and it is easy to cause tooth decay. Moreover, wisdom teeth often experience swelling and pain due to insufficient germination space, and will also invade adjacent teeth, causing toothache. In addition, due to the lack of correct clenching, sometimes the wisdom teeth will over-germinate, which will affect the occlusion; sometimes, the wisdom teeth will under-germinate and become impacted teeth, causing uneven dentition, infection of the pericoronal space, and difficulty in opening the mouth. Wisdom teeth are the third molars and have a significant impact on the adjacent second molars.
Because most wisdom teeth are impacted anteriorly, they are placed on the second molar at an angle of about 45 degrees, thus forming a crown angle, which is easy to impact food, which will lead to caries of the second molar and even pulpitis. Less severe can also affect the lifespan of second molars. Removal of wisdom teeth: Due to the possible diseases caused by the above wisdom teeth, most professionals recommend the removal of wisdom teeth for the sake of avoiding future problems. There are also some people whose wisdom teeth do not cause any trouble to people. This is determined by the individual’s physiological structure. These people do not need to remove their wisdom teeth. Because the location where the wisdom teeth grow is a branch of the trigeminal nerve, if not handled properly, it may affect sensation and even vision in the mouth. In adults, the jawbone and the root of wisdom teeth have already been set, so wisdom tooth extraction surgery has certain risks. For patients with diabetes, heart disease, etc., it is easy to cause complications in the extraction, and the wisdom tooth extraction surgery for these people should be cautious. Because wisdom teeth have 3-4 roots, and the growth position is not conducive to operation, wisdom teeth are generally removed by breaking the crown and dividing them out. Due to the use of anesthesia, there is no pain during the operation, but people need to adapt to the process psychologically, and some people do not cooperate with the treatment because of fear. For some wisdom teeth with less exposed crowns, the gums may be removed during extraction, and the healing of the wounds will bring some pain.
