Front crowns too "thick". Can front crowns be shaven down to match my other teeth?

When crowns are made on the upper teeth, color, shape and transparency must be analyzed, since they are the first teeth to show in a smile. There are different crown materials, and nowadays there are better materials, more esthetic and resistant, than 10 years ago. I would recommend analyzing the possibility of replacing the crowns with ceramic or disilicate crowns.

You can only change those two crowns, and if you are not satisfied with your side teeth, you can have them laminated.

I agree that you cannot simply shave down existing crowns but to do something truly esthetic E max crowns are the way to go in most cases. Although I fabricate E max crowns everyday on my Cerec prime scan these I recommend be done by a master creamiest. One that will not only press the eMax but cut them back and layer feldspathic porcelain on top to create a true work of art that will give you the best esthetic result!

It is not possible to shave down a crown. The best option is to replace them. If zirconia crowns are fitted they can be a better match to rest of your natural teeth.
