Do my eMax crowns need to be reshaped, redone or left alone?

Your dentist did a beautiful job. You might consider shortening the left lateral and left canine by a fraction or two but overall a beautiful result. Two thumbs up to your dentist.Good luck!

Hi:Overall I like your crowns.  My only advice is to shorten the left lateral tooth to match the height of the right one.  This is a very easy fix.Best,Dr. Maddahi

Cosmetic treatments & satisfaction are very personal & differ from one person to another. You might prefer rounder & softer angles & another pt might look for much sharper angles & straight teeth.
They also look different on each person's face depending on the shape of your face, sometimes even your whole body. 
I'll give it sometime to get used to it, also sometimes you get feedback from family & friends that influence your opinion.

From your photos, your crowns really don't look too bad! Teeth shape are a personal preference, and in my opinion, I would like to see a little more definitive angles vs. being round-ish. The other thing I find with Emax is that the crowns aren't as bright as I'd like them to be and that may also be contributing to your displeasure. Having said that, you might get used to them and that would be the easiest thing!
