The difference between gum disease, gingivitis and periodontitis

There may be some confusion in the use of the medical terms surrounding gum disease, but they are fairly simple. Gum disease is the general term used to describe all stages of gum disease – including gingivitis and periodontitis. Gingivitis describes early (and reversible) gum disease, the kind characterized by red, swollen gums that may bleed easily when brushed. If the inflammation and swelling of the gums is not treated properly, it can progress to a more serious (non-reversible) stage of gum disease called periodontitis. Periodontitis attacks the gums, bone, and connective tissue that hold the teeth in place, eventually loosening the teeth over time to the point that they may fall out. Gum disease is the leading cause of tooth loss.
