Can you please tell me how periodontal disease and gingivitis differ?

1st Stage of Perio: Gingivitis is an inflammation of the gum tissue and is the 1st stage of a long destruction path leading to bone loss, gum loss, and tooth loss. All of these are various stages of periodontal disease.

One is worse: Gingivitis is the beginning stages, and by definition, your gums are inflamed, and you might see them bleed when you brush and floss. If this is left untreated, then the infection moves deeper into the jaw, and it progresses to the more severe, periodontal disease.
