I have a question about permanent dental crowns?

i just got an all porcelain crown put on one of my upper front tooth, needless to say it looks bad. the temp. crown i had in was so much better looking and i was ured that the crown was going to be fantastic. i told my dentist that i was very unhappy, and i have an appointment to go back tomorrow to hopefully im umming to get a new one made. But i remember him telling me that my teeth on both sides of the crown kind of go inward so it was hard to make the crown do that as well. isnt that what labs do? fabricate the crown to match the others? not everyone in the world has perfect straight teeth. im not not saying i have horrible teeth but they do slightly go inward a little. my crown right now sticks straight out, like it belongs on someone with perfect straight teeth that go out. is there someone out there that works at a lab and can tell me a few pointers. i just really dont want to go in and get another crown made if its just going to come back looking the same.
