The stage of gum disease you're at depends on the severity of your symptoms. Generally, gum disease is classified into three stages: gingivitis, periodontitis, and advanced periodontitis. Gingivitis is the earliest stage of gum disease and is generally characterized by inflammation, gums that are slightly redder than normal, and mild bleeding. Periodontitis is the more advanced stage of gum disease, and can be identified by deeper pockets that form between the gums and teeth, bone loss, and increased bleeding. Advanced periodontitis is the most severe stage of gum disease and is marked by even deeper pockets, further bone loss, and the formation of abscesses. If you're unsure which stage of gum disease you're at, it's best to speak to a dentist who can assess the severity of your symptoms.
