When it can't be stabilized
Root canal surgery is done by an endodontist.
Yes they can, they did on me.
Yes.
Other types of roots include fibrous roots (found in grasses and other monocots), aerial roots (found in plants like orchids and ivy), and adventitious roots (developing from any part of the plant other than the radicle). Taproots, like those found in carrots and radishes, are another type of root system.
3 (the source is my dentist, he just referred me to get my root canal done on 15th)
what could have happened is that the root canal was not done properly, or the tooth was so damaged that the root canal did not work. In this event, the tooth may have to be pulled (its what happened to me about a week ago)
Yes, in Italy for sure.
there shouldn't be pain
Yes. I had a root canal done on one of mine when I was 10 or 11 and one on the other front tooth a couple years later, as the result of an accident.
It is possible to have more than one root canal treatment on a single tooth because some teeth do have two roots. The need for another root canal can occur within a few weeks of the original one or several years later
A dental post is necessary when a root canal procedure has been done on a tooth that requires a crown. A build up is done on a tooth that needs a crown and has not had a root canal.
Yes root canal procedure can be done under general anaesthesia in certain conditions where patient is highly uncooperative for the procedure.
