Most people need their wisdom teeth removed because there isn’t enough space for them to come in properly. They tend to come in at an angle or they don’t fully emerge. Third molars (the wisdom teeth) routinely damage the teeth right next door, called second molars. When wisdom teeth come in sideways like this, it throws off your bite, creates an area where food gets caught, decays both of the teeth and can even cause a painful infection. Dentists recommend removing wisdom teeth before they become a problem and to avoid a more complicated surgery.
