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. The edges of the gums around the teeth are free and extend as small wedges into the spaces between the teeth (interdental papillae). Internally, fibres of the periodontal membrane enter the gum and hold it tightly against the teeth. Changes in colour, loss of stippling, or abnormal sensitivity are early signs of gum inflammation, or gingivitis. Taking care of your gums may also help to keep your lungs healthy, Periodontal disease is a chronic inflammatory disease that affects the gum tissue and other structures supporting the teeth.
