Wisdom teeth are the set of third molars and are located on each side of the back of the mouth, top and bottom, for a total of four. They usually erupt between the ages of 17 and 25, but you don’t need them to chew your food since you already have sets of first and second molars as well.
When someone has a problem with wisdom teeth, it is often because the teeth erupt too close to the other permanent teeth. The result can be a crowded mouth, an improper bite, and other related dental problems such as the wisdom teeth being impacted; when a tooth is impacted, it comes in sideways and is often quite painful. If your wisdom teeth hurt, they cause you to develop an infection, or the dentist sees some other difficulty after examining you, then they have become a problem.
Unfortunately, many people do have a problem with their wisdom teeth. The best solution is often just having the dentist or oral surgeon remove them while you are under sedation. Anything involving sedation is never completely routine, but having your wisdom teeth removed is worth doing because of the serious, long-term problems wisdom teeth can cause, especially when they are impacted. However, this is a common surgery and is usually straightforward. You should select someone who has the necessary skills and make sure you will be monitored during the surgery so that you receive adequate oxygen.
