If you can see your gums bleed when you brush your teeth and rinse afterwards, it is almost certain that you have gingivitis. Other signs are that the gum edge is redder than further up the gum, and perhaps that edge is slightly thick and swollen. Sometimes there is pain associated with gingivitis, but this is usually in the very late stages of the disease.
