A periodontal examination is performed to diagnose gum disease.  A periodontal probe is used to make several measurements around each tooth.  Pocket depth is one measurement that is made six places around each tooth.  Pockets should measure 3 mm or less and not bleed when probed.  Bleeding is a sign of inflammation.  X-rays are necessary to help assess bone loss.
