Not satisfied with porcelain crown. what should i do now?

I recently (a few months ago) had a root canal and a porcelain crown (porcelain fused to metal) done (at the Dental Cosmetic Center of Houston) to the first 'molar' tooth behind my left canine. Upon arrival at home I looked in the mirror and was a little taken aback by it: I could clearly, easily distinguish it from the rest of my teeth for it had a very prominent dark grey line at my gum line. I asked about this at another visit, and the dentist sort of suppressed the inquiry and said that it "was my natural tooth structure" and that he could not see a line....BS! So after a normal brushing (this is about two months later) I noticed a dark spot on the inner side of it, in the shape of a circle. I tried brushing the hell out of it and flossing it: IT WOULD NOT COME OFF. My mom believes it is the porcelain that has worn off. These crowns are supposed to last a long time.





I want an all-porcelain crown-they never told me it would be a PFM. What should I do now?

Well the line that you are seeing by the gum line, is the metal showing. This part should be tucked up underneath the gums so it is not visible. However old age or receding gum lines can cause it to show way in the future (depending on your age). Also it sounds like they did not pick the correct shade. There are a lot of shades to pick from. They should have matched you up with a shade guide then let you look at the color they chose to see if you like it as well. One thing they are correct about, is that you dont want an all porcelain crown for a molar tooth. They are good for anterior (front) teeth but not molars. The reason why, is because that is where all your biting force is, and it will easily break. He probably knows he messed up, and does not want to admit it, because then he will have to pay the lab about 120 dollars to replace it. He should of had to check it out though before he cemented it. You have to choices either go back and demand he replaces it because you are very unhappy with it, or live with it.
Reply:get in a fight... they'll HAVE to fix it then....just kiddin' I'd get a second opinion and probably sue the dumbass.
Reply:When you say "first molar behind my left canine" I believe you mean first bicuspid as this is the tooth just behind the canine. A PFM crown may or may not have a metal band around it at the cheek gum line. If done at a "cosmetic center" it should have had a porcelain margin which is indistinguishable. It sounds as though you have a regular PFM crown with a metal joint to the tooth. The circle you see sounds like where the dentist adjusted the bite and ground through the porcelain down to the base metal. If all of this is upsetting to you then you need to tell the office that the crown is not acceptable and needs to be cut off and remade. Understand, however, that removing a crown from a root canaled tooth always leaves the tooth open to breaking off when being removed so there's a risk involved. I agree that this office is not up to "cosmetic" standards and is probably just some kind of a clinic.
