I've had an abcess on my gum for about a year. I pop it about two times a day like a pimple. My tooth that needed a rootcanal 4 years ago has started to chip off on the inner part,and is no longer painful. The problem is I can't afford to go to the dentist. Can I expect that tooth to fall out soon? and could that be making me have major pain in the back of my head and upper neck area? Also could it be making me not sleep? Yes I know I need to go right away,but can't get state help or can't afford insurance (which even with its outragous price......) Thank you
