What Is Gum Recession, and Why Does It Happen?
Simply, gum recession is the abnormal loss of height of gum attachment around one or more teeth relative to the rest of the teeth. It usually occurs on the outer surface of the teeth, but may also occur on the inner sufaces. To some degree, a slow type of gum recession occurs continuously with aging and progressive bone loss around the teeth, but we are more concerned with the type that occurs more rapidly and around only a few teeth.
