Will a new crown look exactly like my old tooth? i will be getting a crown for the first time on a left rear molar, and was just wanting to know if they try and make the crown as close to the shape of the old tooth as possible.

Every : Every effort is made to match the current shade of your teeth. The shape should resemble what your tooth looked like previously (or better).

Unfortunately, : Unfortunately, i cannot possibly comment on the work that you will be receiving since I do not know the quality of the laboratory your dentist is using or his/her parameters of quality. If you have any doubts, you might ask your dentist to show you photos of previous work. Also, make sure to look at the crown prior to cementation. Make sure that you approve the shape and shade before the crown is cemented. I am sure that your dentist will try to please you. Best of luck, dr. Zev kaufman.

It : It may not be the right thing to do to copy the original tooth. It needs a crown for some reason, either decay, fracture or other loss of tooth structure. It's shape and contour may be less than ideal. However, your dentist and technician know the ideal size and shape of the appropriate tooth, and will apply those principles when they contour your tooth. They will also make it fit against the opposing chewing tooth and do their best to match the color to the adjacent teeth.

Depends: Whether the shape of the natural tooth, or its position, is best duplicated, or to be improved upon, for long term function... Also, prosthetic materials don't always look exactly like natural tooth structure, so it may look different but be completely fine in terms of what you need.

Crowns vs teeth: Teeth that require crowns usually are defective is some way, whether they are already heavily filled, broken, decaying, non-vital, worn etc. Therefore one does not usually want to replicate them. That being said, I have seen crowns that are indistinguishable from natural teeth and ones that are obviously false looking. It depends upon the tooth, the dentist and the lab.

Crown: It will more than likely be very close to your other tooth in color and shape if the crown is porcelain, if it is porcelain fused to metal or gold, it could be different in color. Your dentist will have most likely discussed materials with you or have chosen porcelain (as that is what most people prefer). The good news is that if it is where you say, no one will see it anyways.
