What does it mean when you have no margins around your crowns?

I had the dentist put in two crowns side by side. I went to another dentist because I'm done with the first and asked her to look at my crowns and she said that there were no margins. Is there a way to fix this? I have to go back anyways to have the first dentist fix the crowns that aren't fitting right. I just do not want to have any more problems than what I have experienced already.

The margins on a crown are where the edge of the crown meet the tooth. If there are no margins, or open margins then the crowns not only fit poorly, but can also have a problems with decay from seepage getting under the crown(s). The margins need to be perfectly flush and when a dentist runs an explorer or instrument over the edge there should be a smooth transition no gaps, no rough area just nice and smooth.


I would give some thought about having the second dentist do the crowns if possible, instead of the #1 dentist. It might be better to have the #1 dentist refund your money/insurance and get them done somewhere else because who is to say the second ones will fit any better than the first ones????


P.S. The only way to fix the crowns properly would be to remake them.
Reply:well im not for sure but i bet u can take the dentist that put the crowns in w/o margins to court b/c the something they have to have in order to be used corectly ...they push your teeth and as time passe your teeth will start to become crooket

Reply:When she said "there were no margins" I believe she was making mention of "no open spaces" where the crown "did not seat properly" on the prep. Not having a space between the tooth and crown is what we try to achieve. The crowns that leave a space or gap, aren't made correctly or to fit the margins or where the prep ends and root begins. These crowns aren't seating all the way down on a prep, this leads to hyper-sensitivity and decay.





Anytime you don't understand what your dentist is saying just ask them to explain it to you. It can save you a lot of worry and grief. Sometimes when we speak between each other, we're not thinking that you are listening and possibly misunderstanding what we are discussing. We are really making a verbal note that is to be recorded in your chart. The only time you should be concerned is when we bring it to your attention and tell you "this has to be replaced" or "needs to be taken care of." So anytime if in doubt, just ask. There are no stupid questions asked in dentistry, only the ones that go unanswered because they were never ask.








Additional information: if you have "no margins" your crowns have been made correctly.





If you have gaps or your dentist can feel the ridge separating the tooth and crown, then they are "not" good crowns and need to be remade.





Hope this helps, I think in explaining the differences between a good and bad crown, it may have become a bit confusing.
