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, develop an infection, or experience other serious dental complications. Therefore, many dentists recommend you undergo a wisdom teeth removal procedure even if they aren’t currently causing any issues.
This isn’t to say that wisdom teeth always need to be removed. Some people have no dental complications, and they simply emerge as another set of molars. Others never develop wisdom teeth at all.
