I've been worried about a compromised immune system as well. That maybe this a symptom of something bigger. I hope that oral surgeon has that in the back of his head. They tried another antibiotic so hopefully that will do the trick..........
Thanks for your help
Your friend's presentation is extremely rare. Abscess tends to subsides within 24 hours after the source of infection is eliminated. Post-op swelling after lower molar extraction is common.However, no more than 3 days in general.The cause of persistent swelling may be associated with infection, which may be managed by appropriate antibiotics, assuming the extraction socket is thoroughly debrided. Another possibility is underlying systemic condition which contributes to compromised immune system.Seeing a competent oral surgeon is advised.
