What is stage one of periodontal disease commonly known as?

Stage one of periodontal disease is commonly known as gingivitis. At this initial stage, the inflammation primarily affects the gums due to the buildup of plaque and tartar, leading to redness, swelling, and potential bleeding of the gums upon probing. This stage is characterized by reversible changes; if addressed properly with appropriate dental care, the condition can improve, and gum health can be restored.

Other options describe more advanced stages of periodontal disease. Moderate periodontitis occurs when there is a more significant tissue destruction including the loss of supporting structures around the teeth, while severe periodontitis indicates extensive damage and potential tooth loss. Advanced gingivitis, although similar, is not a widely recognized or standard term in describing the stages of periodontal disease, as gingivitis itself is the starting point and does not reach a stage of advancement in the same manner that periodontitis does.
