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 four 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 tooth.
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 grow in a special location, which brings many problems to its cleaning and treatment. The diseases often caused include dental caries (commonly known as tooth decay), periodontitis, and pulpitis: because the wisdom teeth are in the innermost, daily brushing is not easy to clean, and it is easy to produce Tooth decay, and wisdom teeth often suffer from swelling and pain due to insufficient space for germination, and will also invade adjacent teeth, causing toothache.
Due to the lack of 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 irregular 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. If the position is relatively correct, it is expected to erupt normally, or the pericoronal soft tissue of the wisdom tooth has no history of inflammation and pain, the wisdom tooth is not decayed, or there is a wisdom tooth that is clenched, it can be considered not to extract. If your wisdom teeth are inflamed repeatedly, it is best to have them removed for good.
