Why did you suddenly grow a tooth?

Adults usually have 28 to 32 teeth. According to your situation, consider giving you a wisdom tooth and how many more teeth.

In theory, adults should have 32 teeth, which are symmetrical. Each half has two front teeth, 65,438+0 canines, 2 bicuspids and 3 molars. The last four molars are also called wisdom teeth. Many adults will never have wisdom teeth, there are 28. Some people will grow 1, 2, 3 or even 4 wisdom teeth.

Wisdom tooth: wisdom tooth (wisdom tooth),/kloc-the third molar that grows between 8 and 25 years old. The third pair of molars grows when young people are about 20 years old, and they are in the intellectual maturity of long body and long knowledge, so they are also called "wisdom teeth". Because wisdom teeth grow at the latest, the distance between the distal mandible and the second molar is very small, which often makes wisdom teeth grow poorly, feel pain, or suffer from gingivitis, so wisdom teeth are also called impacted teeth. Normal wisdom teeth are good for chewing. However, if the position is not correct and it is not easy to correct, gingivitis may be induced. It is better to remove it as soon as possible, which is more beneficial to health.

Overtooth: Overtooth is a common phenomenon. Normal people have 32 permanent teeth, including 8 incisors, 4 canines, 8 premolars and 65,438+02 molars. Any tooth exceeding this number is called "redundant tooth" in medicine. The supernumerary teeth vary greatly, usually conical, and sometimes they can develop into other shapes, even similar to teeth with the same name. Supernumerary teeth are common between two central incisors. The harm of supernumerary teeth is that if they grow in dentition, they will occupy the position of normal teeth. Because normal teeth are rejected by supernumerary teeth, they have to grow out from the side of gums, which leads to the disorder of tooth arrangement. If the supernumerary teeth grow outside the dentition, double-layer teeth will be formed, and there will be a gap between the two teeth, which will cause food residues to stay and impaction, leading to inflammation of gingival tissue and even dental caries. Extra teeth are teeth, which may have bad consequences. Therefore, once there are more teeth, please ask a doctor to identify them and pull them out in time.
