Gingivitis

Anyone besides me ever wonder why on every commercial, ad, and label they always say: "The Gum Disease Gingivitis"... I mean come on is the 'the gum disease' part really necessary? Don't you think we know from the past 50 years of saying it that it's a gum disease?! They don't call cancer 'The Cell Destruction Disease Cancer'---So why do they insist on reminding us that Gingivitis is a gum disease?! Just call it Gingivitis!!
