Why Don't my Crowns Look Like my Original Teeth?

why did you have this work done? Were the teeth broken down or highly filled? or was it to improve your smile? If you are complaining that the crowns don't look like your teeth looked before, then I assume it was not to improve the looks.

Crowns are individually made by a technician following the dentist's instructions and so will not be exactly the same but can be very very similar to your teeth.  To achieve this, good close up  photos of your teeth with the shade tabs should have been taken prior to preparing the teeth. Also, an impression of your teeth should have been taken prior to preparing them.

The final impression taken after the teeth are prepared is to make the crowns on, but it does not give the technician the original size and shape of your teeth. Many dentists just take a final impressions and tell the lab to "make crowns" and a color. So it is up to the lab to make up what they think the crowns should look like. This may be what happened since they look so different.

If you can get a hold of a mold of your teeth and good pictures of you smile before, the crowns can be re-done to be more like you old teeth.

good luck

Dr Neuhaus has given you the perfect answer below.  That is the proper process in fabrication of multiple dental crowns in the esthetic zone.  If this was not performed this is the reason for your question.  Be very mindful on your choice of dentist.  Be very weary of corporate dental "mills" or dentists without proper training in esthetic dentistry.  Let the dentist know you are unhappy with the outcome and see if he/she will work with you.  Any reputable dentist that has gone through the measures that Dr . Neuhaus has discussed below and you are still not happy with the results will try to make it right
