Eating bubble gum's bad for your health

I've just read in the 'time' (an Australian mag) that a dentist from New Jersey affirms that 'The relationship between gum disease and systemic disease, specifically heart disease, has been widely reported.' and that 'The overall ability of the body to heal and stay healthy is certainly compromised by a chronic infection like gum disease.' I'm myself a bit surprised, I knew gums weren't very good for your teeth but I'd never thought eating these little white stuffs could be lethal. Now you know what are the risks... :D
