While gingivitis is the first stage of periodontal (gum) disease, it is distinct from periodontal disease in a few ways. The biggest difference between gingivitis and periodontal disease is that gingivitis can be completely reversed and eliminated with proper oral care and periodontal therapy. Gingivitis refers to a case of gum disease that has not yet caused any permanent damage to your gums, teeth, or jaw. However, gingivitis will always progress into periodontal disease if it is not treated properly. Periodontal disease is not reversible, and can never be fully eliminated.
