How long can I wait after a root canal to get a permanent crown on my top left molar #15?

My dentist can't see me for over a month! 3 weeks after her first available appointment, I am eligible for another fiscal year's worth of dental money. Can I wait 2 months for this crown or should I just find another dentist?

How long can I wait after a root canal to get a permanent crown on my top left molar #15?
The sooner the better, unless noted otherwise by the dentist who did the root canal. On posterior teeth (including tooth #15), root canals have better success rate if a full coverage restoration is placed.


If you have a temporary restoration, no more than 2-4 weeks should go by before you get a real filling. If exposed to saliva, the root canals can get reinfected in less than 3 days!!!


If you have a permanent restoration, depending on the remaining tooth structure, you can wait. There is no time I can tell you, because the tooth can fracture today, in 10 years, or never!!! But our studies show us like I mentionned earlier, posterior teeth with crown have better succes rate...
Reply:you can wait 2 months if you have something in the tooth besides a temporary ( a post and core or a corebuildup ).. that actually restructurizes the tooth and prepares it for a crown.. I highly suggest not eating on that side of your mouth until you do get the crown because it can break....if you can still see the hole from the root canal, then get the tooth built up, if it looks like a stump or a wierd shaped tooth (different from the original shape) you'll be ok for 2 months and possibly longer....they may also be putting it off because the tooth was really bad and they may want to wait and see if it heals good before the crown process
Reply:I work for a dentist. We do not do any crowns on root canal teeth until at least 6-8 weeks later. We do this to make sure the root canal is going to work. Why spend 1000 for a crown if the root canal is not complete. Some people have extra canals that can be missed initially. Some the infection is too severe to alleviate all pain immediately. After a root canal the tooth will essentially die. It can become brittle. You should definitely get a crown, but the rush isn't always for the best.
Reply:Every dental office will tell you something different. I know of some that make you wait a few weeks and others that will go ahead and do it the same day. Ask your dentist what he/she thinks is best. Good luck
Reply:It will be okay to wait just a little while for this crown, but not too long, because the tooth will become brittle and start to break off and you could lose all of the existing crown of the tooth to decay, which is like throwing away money, because the root canal would be any good after that. You can wait 2 months, but not much longer than that, just make sure that you brush and floss on a regular basis to keep that area nice and clean, and when you can't brush right away, rinse your mouth with water.
Reply:The very same day. I got a root canal done in mexico (cheap) and they put my crown on the same day
