Impacted wisdom tooth. Coloured X-ray of the mouth showing an impacted wisdom tooth (highlighted yellow/magenta, centre left). The patient is also wearing a removable brace (white, upper centre) on the upper jaw to help keep the teeth aligned. The molars (back teeth) have amalgam fillings in them (white). The emerging wisdom tooth at left is growing sideways into the molar tooth next to it. The wisdom tooth at centre right has grown through normally, behind the filled molars. Wisdom teeth usually erupt between the ages of 17 and 21. Impa- cted wisdom teeth must be extracted if they cause problems such as a gum infection, or if they push adjacent teeth out of alignment.
