Color choice with dental crowns (Photo)

Hi, I think that if you choose B1 it will be too bright in relation to your lower teeth. Hard to tell from the photos but you appear to have some grayish on the lower teeth. The C range may be better. It is hard to tell with temporaries as they are not made of porcelain and so you have a hard time comparing. Usually the porcelain crowns are much better. Word of caution don't cement real crowns until you are very sure that you like the color. I would suggest you bring a friend that will be honest with you and can give an unbiased opinion. Good luck.

Hi:Due to the grayness of the bottom teeth there will definitely be a crash in color between the upper and lower teeth if you pick B1 shade.  On the other hand if you pick C1 shade it matches the bottom teeth, however it may not be esthectially pleasing.  Since your smile depends on your upper teeth, my recommendation is to go with your ideal shade on the upper teeth.Best,Dr. Maddahi

Hello,The best way would be to do in office power teeth whitening first to see how white your natural teeth will whiten, and then match the crowns based on that. You can maintain your result by take home teeth whitening trays that your dentist can fabricate for you.Hope this helps,Dr. Mazaheri

Final shade determination is a very difficult decision and it is a topic that I discuss at great length with my patients before starting treatment. 
It is normal for your temporary crowns to look different than the vita classic guide, and it is something that I am not concerned about. The temporary crowns are monochromatic (one shade) while the color on the shade guide is more like what your final crowns will look like as it is layered with areas that have more color and other areas that have more translucency. 
As for the final shade determination, it does appear that your lower teeth are in the greyish tones and that is why your dentist chose C1.  Without seeing you in person, it is impossible for me to determine if B1 will blend in. My recommendation is for you to go back to your dentist to go over once again your different options for a final shade so at least you have piece of mind that the color you and your dentist choose is the right color for you.
