hi. once the tooth has been taken out of the oral cavity and any complication like dry socket
, if develops and heals successfully, then, it has absolutely nothing to do with any sort of cold/ fever
it may be most likely a coinicdental problem. moreover if you still suspect, the tooth to be a reason for all this, you may ask the dentist
to take a Xray of that area, to make sure, nothing remians inside the extraction socket. Now Foul smelling mucus and stuffed nose can be treated with inhalation of steam along with warm saline gargle and antibiotics for a few days.
