In the absence of professional treatment and better home care, gingivitis progresses to the next stage, which is known as periodontitis. In this stage, the connective tissue and bone that hold the teeth in place begin to break down with an increase in pocketing between the teeth and bone, gum recession, and bone loss. Without proper treatment by your dentist, periodontitis will progress from a mild to moderate loss of supporting tissue to the destruction of the bone around the teeth.
