  • Crown broken off molar with old root canals: I had a molar on top left 2nd one in. It had two previous root canals!! Now the crown top part of the tooth has broken off. I'm wondering if I could just leave it or is it best to get it pulled out? If it gets pulled out will my front teeth begin to shift? ...Visitor from Page AZ     (answer)

  • I had a root canal done on tooth #14 in 2002, then it got infected again and retreated in 2007, at which time an x-ray was taken showing a dark shadow on this tooth root. In Dec 2012, an X-ray during routine check-up still shows the dark shadow, no worse, no better. I have no symptoms at all. Could this dark shadow be a benign scar and can be left alone without causing major trouble, or could it be a chronicle abscess? My gum has been in perfect condition for years since the retreat. Should I take the tooth out now for peace of mind? ...Visitor from VA     (answer)

  • Gum pain under crown with root canal: I have pain and swelling of the cheek, jaw bone and gums under and around the crown. When I bite down on the tooth it does not hurt. Not sensitive to cold or hot. My dentist x-rayed the tooth and did not see a abcess. My dentist recommended to pull the tooth and place an implant. I feel like they want to sell me a implant. The root canal is about 10 years old. The swelling and pain goes and comes. Should I see another dentist? ...Visitor from TX     (answer)
