Do my veneers look normal? I'm 4 days post op. I cannot decide if I want to go back to dentist because they feel too long.

Your porcelain veneers look fine, I would wait couple of weeks, to see if you adjust to them, before shortening it!
shortening the veneers might give you wider teeth, in which you might not like!
Once you shorten you can not add length any more, and see if you can pronounce the letters such as "s" or "m" correctly prior to shortening them, as far as the bulky part see if you can get used to it.
The good dentist can not take the bulkiness away, but he can shorten it, if need be!

Hi:I would wait a week before doing any adjustment.  The veneers appear to be a little too long, however full face picture is necessary to determine proper length as well.Best,Dr. Maddahi
