can tooth infection cause arrhythmia? I still have a small infection since my canine was removed last Nov. 3rd. Since a month my heart skip a beat? I know the infection is still there. I was on antibiotics for 10 days last November, but now my dentist doesn t want to give me more antibiotic, thinking the infection is coming from my gum ... but I know from the x-ray there is still an abcess there. Is this possible ... also need to add I had a tremendous stress that lasted almost 3 months .. at the same time of my teeth job.
