My wife was recently told she needed a root canal after experiencing some pain under her old crown. The dentist also told her that after the root canal a new crown would be needed to replace the old one. After the root canal was done she went to have the new crown done but was told the existing tooth was to deteriorated for a crown. Is it normal for a root canal to be performed with the old crown in place? Thank you
In most cases when a patient is experiencing pain where there is an "old" crown it is due to the tooth having decay under it. The most common reason is because it is no longer properly sealed & bacteria is filtering in. Other times the crown may be properly sealed & it is just reacting to the trauma caused by the actual preparation, which occasionally happens as well. Every case is different & every dentist treats differently but I usually recommend taking the old crown off to properly evaluate & see if there is enough tooth structure to properly do a root canal, post & crown. Good Luck
I recently got two crown lengthing/crowns. I waited a month between the lengthening and crown. It's two weeks later and I'm still throbbing in pain. It's hyper sensitive to cold. Now he says I need a root canal, without even looking in my mouth. I'm suspicious that two teeth suddenly need canals and suspect the process. These new crowns are all ceramic (not metal on ceramic) and I read the cement used might be the issue. I'm leaning towards getting a second opinion.
It could be a list of many factors and without seeing an x-ray and doing a clinical exam, any dentist is just guessing. If its an all ceramic crown, it could be poorly bonded on. Bonding is an extremely technique sensitive procedure and any moisture or conataminant that gets under the crown could potentially cause sensitivity. If you take your finger nail and press into the crown and you get a slight zinger, its mostly a bonding problem. If thats what it is, my advice is to have the crowns taken off and re-done. Sometimes the sensitivity will go away on its own but that can take up to a year. Make sure your dentist is properly trained when it comes to bonding restorations. Good luck.

I recently had 5 crowns put on my top front teeth. Three of the teeth were chipping quite often so the dentist said I should get crowns on all 5 so they would match. One tooth broke off after one month; another broke off after 3 months, another broke off yesterday. I've had to have root canals and new crowns on the first two. Now I'm wondering whether to get another crown on the 3rd one. I'm worried it will just break off again. Do dentists have to guarantee their work?
Many times the bite is compromised in the front and if you try and restore already broken teeth in the front you could end up with the same tension that always existed. It could also be dentist error and the crowns are not bonded correctly. Many factors could be the problem and I would seek a second opinion with a cosmetic dentist. Good luck!
