Hello. I am experiencing massive oral pain on the upper right side around my canine tooth. A little history: When a younger man in my teens (now 50yrs old), I a very bad head cold and sniffled very hard and heard a loud snap sound from my nose. Every since I have had constant sinus congestion and pain on the right side of my nose/sinus area. Over time, the pain moved down into my mouth around the canine tooth and I had to have the tooth remove and a bridge installed. Since then I have had massive swelling around the gum area and can taste a very salty rotten flavor in my mouth. If I create a suction in my mouth, I can sort of milk the substance out of my gums. Over time a lump has formed over the canine area on the roof of my mouth that is tender and sore. I have been to several maxiofacial surgeons and have twice had the tissue along the gum line cut open and my face peeled up so they could look around in the area just right of my nose. They have removed some scar tissue and scraped the bone, but have found nothing to cause the drainage or pain. I have had root canals done on all of my teeth in the immediate area, and have been to several ENT specialists (all of which can find nothing wrong with my sinus area) with no luck. The pain is usually unbareable and nothing (over the counter) even comes close to stopping it. This week I went to my dentist to get the bridge repaired / replaced, and he did some laser work around the gum area and stitched shut a hole (intentionally done by the surgeon to allow drainage) left by my last maxiofacial surgery 3 years ago. He felt the hole in my gum tissue was the cause on the foul taste in my mouth due to food getting trapped in it and his thinking is that by now (3 years later) it has most likely served whatever purpose needed. I simply don t know what else to do and have spent many 10 s of thousands of dollars trying to correct the problem but it still persists. The pain and soreness is mind blowing most days affecting my eating, sleeping, speech, and general mental health. I do smoke about a pack of cigerettes daily and thought you may need this info. PLEASE HELP!!!
