ha ha! ok ok. but still! Its not going to do anything for gum DISEASE. Maybe a jacked up tooth. Gum disease is inflamation of the gums do to hardened plaque irritating them, causing them to swell and receed. They give you a prescription mouth wash to use for 2 weeks to make the bleeding stop and swelling to go down. and in that 2 weeks you gotta come up with a hefty amount of cash to have needles shoved in your gums so they can clean your teeth. Maybe penicillin would work for an absessed tooth but its not going to help before going to the dentist. Now trench mouth. Which comes well after gum disease, penicillin would probably prevent sudden death.
