No electric brushes don't do anything for gingivitis, on the other hand rinsing your mouth out right after you eat anything will help, because when the food stays in your mouth the bacteria that normally live in your mouth start having a party and procreate and increase the population of bacteria which try to invade your body through your gums, your body in turn fights back by diverting the blood supply to the port of invasion ie your gums. So by rinsing you mouth after you eat you decrease the amount of food available and don't allow the bacteria to multiply. And if you don't allow the acidity of your mouth dip down to ph of 5 for 5 minutes, by rinsing, then the acid won't be strong enough to dissolve tooth structure and if it doesn't dissolve you won't have decay!
