Many people don't realize that there may be 3 - 4 canals in a tooth and sometimes the dentist may miss the extra canals. Also some dentists will do the root canal and fill the tooth, but a crown or cap is the answer. If it's filled it could be the filling causing the agitation. Please see your dentist for the proper diagnosis.Personal Experience:
I HAD A root canal, and topped it off with a $1000.00 crown (gold and composite). About two to three years later, I began to have a little pus "pimple" appear on my gum line near that tooth. My dentist is one of the best and has done about $10,000.00 worth of work in my mouth over the last 12 years. He checked me out and said that he had missed a small piece of "root" in one of my "canals". He apologized, of course. He then drilled a small hole in my cap and crown and sucked out that piece he missed two years ago. He then filled the hole in my crown with a special composite material. If in doubt, SEE YOUR DENTIST.
