Tooth with Root canal question?

I had a root canal on a back molar about a year ago, but a cap was never put on it.... now i can see a small hole in the side of the tooth that had the root canal. So now i am just wondering whether it is likely or not that i will need the root canal re-done on that tooth due to the hole or whether the dentist will just be able to fill the hole just like any other cavity????


Thanks

after a RCT, a crown must be fixed because the enamel becomes very brittle due to lack of blood %26amp; nerve supply. If it does not hurt, go get the crown fixed, no need to get the RCT redone.
Reply:Roots canals are sually not re-done. Most likely you have a cavity and will have to have your tooth pulled out. Ouch! Fly to the dentist.
Reply:You will probably need a post and core buildup if you had not already had one. The crown will be placed on top of that so you wont have to worry. Dont wait too long, a root canal treated tooth has no more blood supply so it is very brittle and can beak easily
Reply:Once they take an x-ray...the dentist will determine the extent of decay.Often times just a little drilling to clean out the cavity will do.It all depends if the infection is deep enough to require a root canal.But most likely a simple clean-out will do.Just make sure you cap it or all that work will be useless.P.S. try and get a porcelain crown....they are the best!
