I had an infected tooth extracted (simple extraction, upper molar) 5 days ago.  My face is still swollen, the right side of my mouth cavity is sore, and the extraction site is painful, as is the tooth next to it.  Yesterday, day four, I had severe chest and left arm pain.  Went to the ER and tho I told them about the tooth extraction, the best diagnosis they could come up with was unstable arrythmia.  Do you think my infected tooth has something to do with the chest pain?
Hi, Thanks for posting the query, I would suggest you to get an x-ray done of the region to see if any leftover root particle if present inside the cavity, take a course of antibiotics and analgesics prescribed to you, at home take lukewarm saline and antiseptic mouthwash rinses, apply some ice externally to the swelling. Take care!
