The wisdom teeth, scientifically known as third molars, are considered normal from none to four and are located at the end of the alveolar bone in the upper and lower jaws. They usually appear after the age of 18 years in adults, but due to nutrition and development, it is not uncommon for children to have wisdom teeth as early as 15 or 6 years old. It is not uncommon for wisdom teeth to appear as late as age. However, the vast majority of wisdom teeth appear between 18 and 20 years of age. For modern people, wisdom teeth are a paradox. The reason is that due to the degeneration of human beings, the jawbone that could accommodate the lower wisdom teeth is often underdeveloped, resulting in the wisdom teeth not having enough space to live, and can only grow crookedly and obliquely, manifesting as obstructed growth. Therefore, for most modern people, wisdom teeth are not only useless, but also harmful, so they are often pulled out as soon as possible. From the point of view of God’s creation, wisdom teeth were meant to be used for chewing food, but they were abandoned due to the degeneration of human beings. However, there are still a small number of people who can erupt normally, so it is certainly not necessary to remove them. In addition, more importantly, due to the fine food, high sugar content, and improper health care, the proportion of tooth decay is very high in modern people, and the first two molars, which are very important for chewing food, are easily affected by tooth decay, and their functions are damaged to different degrees, and serious cases have to be extracted. At this point, wisdom teeth can show their important value. We can use certain orthodontic methods to move the wisdom teeth to the position of the broken first and second molars, thus replacing their function and playing the role of waste utilization. Wisdom teeth are real teeth, and their function and longevity are far from being comparable to even the best dentures. Are wisdom teeth useful or useless? It really depends on the circumstances. So, if you have a decayed tooth in your mouth and an obstructed wisdom tooth at the same time, you may want to get a consultation with an orthodontist who may be able to bring your wisdom tooth back to life!
