Tooth extraction and Bad Breath

Hi. So glad I found your site. Two weeks ago I had a tooth extracted (third one from my top wisdom tooth) due to a crown breaking months before. The oral surgeon said in my consultation that the procedure would be a bit more involved than a typical extraction since the roots were so close to my sinus wall or membrane. The surgery went well and at my ten day post surgery check-up he said things were progressing normally although I still had some healing to do. While the inflammation around three-fourths of the tooth has healed significantly, there is one corner of my gum area surrounding the tooth that is still inflammed- puffy to my tounge's touch and very, very sore. There is still considerable pain in the surrounding bone area and into my front cheekbone above the extraction site. I don't, however, feel that I have a sinus infection- at least not that I can tell.
All of that said, my real issue is the terrible resulting breath odor. It is beyond bad. It is beyond horrible. I did read about the benefits of epsom salt in another post. Would that be helpful to me or should I follow a different path given that this is related to a surgical procedure? Your information is so appreciated.
