Can someone advise how likely a tooth infection could cause arrythmias? Nearly 4 years ago, I had a root canal done for an infected tooth. Now jump a few years later, I find out that it was a failed procedure and there was still an infection at the same location. The oral surgeon said I did not feel it since the root was killed by the laser procedure, but over the few years, I did feel a pain that came and went in the area of my jaw. 3d scan revealed that the infection had been slowly taking away part of my jaw bone. The oral surgeon specialist said that this might have been the root problem of my heart issues of v-tach over the same period since the failed root canal procedure of a few years ago. Why my dentist did not pick up on this infection over the last few years is beyond me. Be as it is, I am curious as to how much a such an infection could be a cause of so many incidents that caused my defibrolator to fire with me ending up in the hospital. I welcome your feedback please for my education. Thank you all!!
