Very big front teeth with a very gummy smile - What can be done? (Photos)

I have very big front teeth with a gummy smile. I feel as though they look huge, like big bunny rabbit teeth. I have an over bite too. I had braces when I was teenager and was going to have jaw surgery to correct my bite but after my treatment I was talked out of it and at the time was happy with the results the braces alone gave me. Now I am an adult and I wish I had gone through with the procedure all them years ago, as never been happy or confident about my teeth! I’m now 40 so having such a big procedure is not really an option. Is there anything else that I can do to make my smile more attractive using cosmetic dentistry.
