Root canal treatment?

i did a root canal treatment and at that time the doc said that the root should be killed. that was fine for me...6 months later i started to have deep pain in the same tooth. went back there and and this time the doc says that its better to take out the tooth...why if the root is dead?And why was it painfull if the root is dead?

Root canal treatment?
Sometimes there can be an extra root/vearing off root that is not seen/treated at the time of treatment b/c it isn't visible and it is an anatomical deviance. You could be seen by an endodontist/specialist in root canals and have a consult and possible get the tooth retreated and that usually fixes the problem unless there is more going on that you have explained. Like a huge cavity/decay down to gumline/undergumline.
Reply:Both good questions - one's you should ask of a NEW dentist/doctor. Root canal is supposed to kill the nerve. You need a second opinion.
Reply:It happens when the root canal treatment has not been done properly. Basically in a root canal what happens is that all the nerves and blood supply of the tooth is taken out (from inside the tooth) and the apex of the tooth is sealed,after that the canal in the tooth (which carried the blood and nerve supply) is filled with filling material.


when the apex of the tooth has not been sealed properly, tissue fluid from around the apex goes in the canal, and since there is no blood supply, it becomes necrotic (dead) and microorganisms start habitating there.


the necrotic debris then comes out in the tissues surrounding the apex and forms an ulcer kind of thing.


so the pain basically comes from the tissue reaction which takes place surrounding the apex, and he wants to take it out, to take away the irritating factor.


i hope this answered ur question completely.
Reply:Root canal treatment only has a 70-80% success rate as there are often extra canals branching from the main root canal that is filled. Just because you're getting problems doesn't necessarily mean it hasn't been done properly as a couple of the other answers suggest. Referral to a specialist endodontist, or extraction of the tooth are your main options.
