Can a cemented crown be altered? (photos)

I had a crown placed recently for cosmetic reasons, as well as for strength of the tooth. the temporary wasn’t the best color but it was the right shape and size.. I now have the permanent crown but I didn’t realize while I was at the dentist that it is so bulky. Its also too long. It’s giving me a lisp and my bottom teeth hit it when I chew. My natural and temp tooth did not protrude. I approved it, but it was hard to see while there.
