Does anyone know anything about gum disease?

Does anyone know the first signs of gum disease please?

bleeding, receding gum line sensitivity smell

I expect there are more accurate ones

Bleeding gums, bad breath...it is easily treated in the first instance - flossing is helpful. Some dentists say that electric toothbrushes are effective. There are some kinds of mouthwash that are helpful that you can get from the dentist.
