I had a root canal 6 years ago and i'm due to get a crown. the dentist said i won't get an injection. will this be painful?

No nerve: It is possible that we can have a crown on root canal tooth without the shot or numbing, if your dentist only planned to place your crown above the gum line and not going to touch your gum tissue.

Probably not.: There is no more inervation to the tooth, so you should have no tooth pain. Sometimes, however, preparing the tooth involves touching the surrounding gum tissue. That should be no problem, but sometimes, though rarely, it is.

Shouldn't be: The only reason for the injection would be if your gums were going to be worked on too. A lot of people with root canals don't need anesthetic for those teeth to be worked on.

Not necessarily: When the root canal was done, the tooth's nerve should have been removed. This eliminated the tooth's ability to sense pain. It should be remembered, however, that the gums, bone, ligaments, etc. Around the tooth will still be very much alive. Some procedures during the crown process can be uncomfortable to the supporting tissues of the tooth. It depends on what your dentist will be doing.
