Gum recession is a loss of gum tissue along the gum line. Gum recession can occur because of periodontal diseases like gingivitis, periodontitis, and advanced periodontitis. It can also occur from brushing your teeth too hard, brushing using a toothbrush with hard bristles, or just because of your body’s natural aging process.
The roots of the teeth that are exposed during the recession of the gums can be sensitive both on cold and hot. The recession of the gums sometimes can cause more health problems even losing of the teeth.
