When would a dentist recommend an onlay and when would a dentist recommend a root canal? If tooth decay is not treated, would it result in a root canal? I understand it makes sense to preserver the existing tooth, but cost wise, which is more effective – an Onlay or a Crown?

So a root canal is needed when the tooth dies and becomes infected, is there any way to prevent this from happening?

I’m just wondering when a dentist decides to do a root canal, what is he generally seeing?

My family dentist attempted a root canal but couldn’t finish it. He was unable to get thru one of my canals. The endodontic specialtist will finish the job but it’s over 1450 just for the root canal. I still have to go back to the family dentist for a filling on the metal crown that is on the tooth.

I had a root canal 5 days ago. The tooth is still pretty sensitive. It hurts when I brush my teeth, or even put a little pressure on it with my tongue. I was wondering if this was normal. I guess I didn’t think that just a tiny bit of pressure from my tongue or brushing my teeth would cause pain. Also is it ok to floss right now?

My front teeth are kind of dark in a spot inside my teeth. I’m guessing its from my teeth getting hit because all of my other teeth are white. My dentist recommends a root canal but I have a fear of the dentist office. Is there a way to whiten inside theeth?

My boyfriend has a root canal and he wants to know how he can numb or make it stop hurting it for a little until he goes to the dentist because it is bugging him…

Is the instrument suppose to be there? They want me to go to a root canal specialist. Is this necessary?

I had one of my molar extracted last year and now I need a root canal on another molar – tomorrow, I am scared to death.
What is worse, extraction or root canal?
P.S Root canal is with an Endodontist, Specialist.

During a recent cleaning, the hygienist said she suspected a pocket was forming in the gum over a crowned tooth that also had a root canal. She took a root x-ray and said it showed decay. Is this possible?
