When i apply suction to a certain part of my gums near a certain tooth, an excessive amount of blood comes out. ?

Gum Disease: First sign of gum disease is something as simple as blood in your toothbrush. Most people ignore this because there is usually no pain associated with gum disease until it is on the advance stage. Tooth movement or drifting creating gaps between teeth, gum recession and bad breath are also signs of the disease. The only way to diagnose it is to have a full periodontal examination by a dentist.

Oral bacteria: The evaluation should include a bacterial assessment and nutritional work up.

Infection: Sounds like a gum infection with a possible abscess or draining fistula. See a dentist as soon as possible.
