Gingivitis and bleeding gums is usually caused by the inflammation of the gums around the teeth. Gingivitis or hemorrhaging gums results from the bacteria within plaque which is caused by improper cleansing of teeth. Gingivitis is a modern disease and may go undetected within the early stages. The first indications are actually bleeding when you floss, and swelling in the gums. Because this may trigger no pain, most people are unaware they have a problem.
An important aspect of gingivitis to remember is that it is reversible. This reversibility is in contrast to periodontitis, a more severe gum disease can impact the bone that support your teeth.
