What procedures should I go for to fix my misaligned smile/teeth?

Hello, hope all is well. As shown in the pictures, my smile is very misaligned. It's a bit obvious in the pictures, but it's a little more pronounced in real life. It also seems like my nose is drooping with the part of my mouth that is lower. I've had braces in the past, but it didn't really contribute to fixing my mouth's misalignment. What procedure should I go for to fix this misalignment?
