Gum recession is the loss of gum tissue from the base of a tooth with exposure of the root surface.

Recession usually occurs in response to overaggressive brushing but can also result from injury or as the natural progression of thin, delicate gum tissue. Most people have some slight recession.

Recession may make the teeth very sensitive to cold, to sweet foods, or to touch. It may be accompanied by bone loss and may make the teeth more vulnerable to root cavities.

Treatment is needed when the gums or teeth are sensitive or when plaque accumulates and is difficult to remove. Treatment involves a grafting procedure, in which soft tissue is removed from the roof of the mouth or from donor tissues and stitched to the area.
