Dental Question? I got my two front crowns put in today and...?

They are not the same shade as my other teeth. They are a tad bit darker and a tad bit yellower. I could not see this in the dentists office with the lighting in there. Now what??? They are permanently cemented in. Is there anything that can be done?

Dental Question? I got my two front crowns put in today and...?
Crowns will look different in various lighting. Dental offices usually have natural lighting [looks like fluorescent, but its not], so the crowns probably looked perfect there. If ur not happy, call them and ask what can be done. Are u sure they are cemented permanently, or just with a temporary cement? They will probably come up with a whitening solution, that will whiten your natural teeth. That should have been an option b4 hand. Good luck
Reply:You can ask your dentist, or use a whiting paste or wash. I've never had them but my friend did and they did look yellow or not normal, so i think they will just have to stay like that =)
Reply:Tell em they screwed up your teeth and you want your money back! And if they don't help or give your money back ummm try some bleaching(they should give cuz they screwed ur teeth up) or some Crest whiting strips!
Reply:When it comes to crowns there is no such thing as permanent. If the color is off go back to the dentist and point it out to him or her...In most cases there are one or two reasons crowns don't match the natural teeth...(1) The dentist failed to provide the dental ceramist the proper shade number or (2) the ceramist failed to match the shade number he or she was given...In any event you are entitled to crowns that properly match the surrounding natural teeth...It's not magic and it's not impossible, some one simply goofed. There is the possibility that the colors of the walls in the dentist exam room wasn't conducive to being able to select proper tooth shades for crowns...If necessary have him look at the difference in-outside light, pick the proper shade in that setting and "remake" the crowns....I was a ceramist for 22 years and I know what I'm talking about.
Reply:When restoring front teeth with crowns or veneers, it's very challenging to get the color right, when facing such scenario, a lot of dentists try to restore 6 front teeth together with Veneers/crowns to make sure color matches.


The fact that your crowns looked ok in the dentist office, and different color later (at home?) is due to the fact that crown's porcelain reaction to the amount of UV in the lighting is different than your natural teeth under different lighting conditions, and even the best matching crown will show this kind of shade discrepancy under different lighting, it's simply the porcelain fluorescence under UV light. most dental offices have corrected light that simulate the sun polychromatic light, including UV, just to get to as accurate shade match as possible.


Without getting into these details, to solve this problem you have 3 solutions:


1) Understand the limitation of restorative dentistry and try to ignore the fact your teeth color doesn't match properly, and simply live with it.


2) Try to restore the adjacent teeth with veneers/crowns that matches the shade picked for these 2 crowns, this is the most expensive option, and probably the most aggressive as well, but usually guarantee the best cosmetic outcome, your dentist might elect to remake these 2 crowns to achieve better color match.


3) Remake these 2 crowns only, and ask your dentist for a custom shade match, the lab tech will come over to pick the shade of your teeth by himself for little extra charge. From my experience, it's really hard to achieve this kind of accuracy, unless you are working with a high end lab tech who has good experience with cosmetic dentistry, and sadly not too many of those exist.


I would pick option 1 if the color difference is not that bad, if it's really bothering you or the color is way far off, try changing the 2 crowns only. Otherwise you are left off with the extreme smile make over option.


Hope that helped.


Good Luck
