If a wisdom tooth doesn’t have enough room to grow it becomes an impacted wisdom tooth. An impacted wisdom tooth can grow at an angle into your molars, grow backward, or become trapped by the jawbone. When this happens you can experience pain radiating even to nearby teeth, gum disease, develop an infection, or experience other serious dental problems or complications on permanent adult teeth located near the wisdom tooth. Therefore, many dentists recommend surgical removal versus retention of your wisdom teeth even if they aren’t currently causing any issues. It could be done in the dental office or through oral and maxillofacial surgery.
This isn’t to say that wisdom tooth removal is always a necessary procedure. Some people have no dental complications, and they simply emerge as another set of molars. Others never develop wisdom teeth at all or no wisdom teeth erupt.
