Tips for lengthening short teeth/fixing a gummy smile?

I believe my top row teeth are too short, and I’d like them to be longer and overall have a more attractive smile. I’d also like to improve my pointy canines and even out the top row of my teeth with veneers. Also when I smile/laugh it is very gummy and I’d be interested in fixing that too. My 4 front top row teeth are currently composite porcelain resin, so I would also have to get that removed and replaced. Any suggestions and observations would be SO welcome! Thank you.
