Gum , also called gingiva, plural gingivae , in anatomy, connective tissue covered with mucous membrane , attached to and surrounding the necks of the teeth and adjacent alveolar bone. Before the erupting teeth enter the mouth cavity, gum pads develop; these are slight elevations of the overlying oral mucous membrane. When tooth eruption is complete, the gum embraces the neck region of each tooth. As well as being attached to adjacent alveolar bone, gum is connected to the cement of each tooth and to the tooth enamel. Healthy gums are pink, stippled, and tough and have a limited sensibility to pain, temperature, and pressure. The gums are separated from the alveolar mucosa, which is red, by a scalloped line that approximately follows the contours of the teeth.

Teeth Names & Numbers
Between the ages of about six months and three years, you watched as your child got all of his primary teeth. Starting around the age of five or six, you get to enjoy the process all over again, as those teeth fall out and the permanent set erupts. Although it only took a few years for your child to get his primary teeth , it can take a decade or more until the final permanent tooth comes in. To help, you can use a permanent teeth chart to keep track of which adult teeth come in and when. When a child's teeth start growing can vary, but they generally erupt in the same order for everyone.
Tooth Anatomy: Know The Parts Of Your Teeth
Bacteria can enter the innermost part of the tooth through either a deep cavity or a chip or crack in your tooth. The resulting infection and inflammation can cause an abscess at the tip of the root. A tooth abscess is a pocket of pus that's caused by a bacterial infection.
