My wife had four teeth extracted 11 days ago,  she had sinus pain and crackling in her sinuses and neck after the extractions,  but it cleared up. Today she had mouth molds done for dntures, after the molds were made she has once again been feeling the sinys pain, hearing crackling and had a slight runny nose with clear discharge,  any idea whats going on,  and what she can do?
Thanks for your query, I have gone through your query. The sinus pain and runny nose can be because of the or astral fistula or communication, which is a complication of extraction of upper molars. Nothing to be panic, consult an oral maxillofacial surgeon and get it evaluated, if the communication has not healed, it has to be closed surgically. If it has healed, nothing to worry, go ahead with the dentures. I hope my answer will help you, take care.
