crown cemented correctly or not, should I worry?

[raoulcarr]

I recently had a crown put on my upper molar because the tooth was cracked. The dentist said he cemented the porcelain crown in permanently but used Duralon instead of a newer cement and said that he could still remove the crown. I'm worried because if the crown can be removed it means to me that it isn't cemented in permanently, and that is the question. If the crown can be pulled off without damaging the crown, can this still be regarded as a permanent cementing. I am worried that the Duralon will leak out and/or infection will get in there and rot out this recently crowned molar.  Please advise if I should have crown removed and re-cemented with a more permanent cement or would this put too much stress on the tooth. THANK YOU ALL VERY MUCH

Hi there!  If that tooth has had a root canal, there should be no sensitivity because there is no nerve.  UNLESS there was an extra canal that did not get filled.  Sometimes that happens.  Which tooth is it?  If there is an extra canal that didn't get filled, don't think you had a bad dentist necessarily.  It's not that uncommon.  That may be where the cold sensitivity is coming from.  Are you sure it's the tooth that was just crowned that is sensitive?  We have a lot of patients that think it's one tooth but it's actually a different tooth.  Also, how old are you?  We usually don't recommend fluoride rinse for anyone over 18.  It's just not really necessary.  Your teeth are done forming after a certain age and you'd probably be better off rinsing with Listerine or some other bacteria killing rinse rather than a fluoride rinse.  Hope this helps!

i am nervous as well for the crown i had placed on laast monday. the bite was high so i had the crown adjusted thursday. since then i have had sensitivity to cold water. it was pretty strong for a couple days after but has died down since. i still get a little sensitivity occasionally. and i cant tell if its all the way under my gum or not. either way i brush twice a day and am making sure i floss and rinse with act fluoride rinse before bed. the tooth had a root canal before the crown. i am nervous it will decay as well and scared

I honestly think your tooth is fine under that crown.  The only problem your tongue poses by touching it is that it would get it wet.  And your dr probably made sure it was properly dried if your tongue did in fact touch it.  As far as germs or bacteria go, I think you have nothing to worry about.  If it's sensitive to biting, it could just need a simple bite adjustment.  Make an appointment to see your dr.  I really don't think you necessarily need to remove it and redo it.  Sometimes, especially if there was a fracture, it takes some time for the tooth to heal.  Talk to your dr about how bad the fracture was.  Was he able to eliminate the fracture line or fractured cusp?  If so, I believe it has a good chance of a long life!  Good luck!

  Dear Kimmeh9:Hello and Thank you greatly for your response. I know it is lot to ask but I do have some other urgent questions.When I had a crown put on a molar recently the dentist did not wash off and dry the tooth before cementing in the crown with Durelon. I know I got saliva on the tooth and did touch it with my tongue. I am worried about any bacteria on the tooth under this crown and also about the Bond. Would any bacteria be killed by the Durelon and/or would there be any risk of anything bad growing in this sealed environment? If so, then how urgent is it to have this crown removed and re-cemented? Would the crown be easier to remove now or should I wait? The crown was a good fit. Would not washing and drying the tooth before cementing weaken the bond, making it easier for infection to get under the crown? The crown was put on because the tooth was cracked but now 5 days later I still feel some pain on biting. Does the crown prevent this from getting worse? Bless you and much Thanks for all your help, Sincerely, Michael Carr, ***@****

Hi!  I have been a dental assistant for over 15 years.  We use Durelon to cement crowns in everyday.  We have a stronger cement but if there was ever a problem with the crown, we wouldn't be able to retrieve it.  We use Durelon because it keeps the crown on very well but if the porcelain was to chip, we would be able to tap off the crown and send it to the lab to have it rebaked.  It is also very "nice" to the tooth.  Many stronger cements draw moisture out of the tooth and can leave it very sensitive.  If your tooth was prepared correctly so that the crown tucks under your gums, it should never leak or decay.  Rest assured, your tooth should be just fine.  I would be more concerned about the fracture under the crown.  Hope this helps!
