What’s the best procedure to contour my undefined jawline and achieve a v - shaped face? (photos)

My jaw sometimes looks pear shaped especially in the left.Not sure if it’s only because of my misaligned jaw due to poor braces work.I also have fat pockets under my lips whice contributes to the overall look. I have undefined jawline & chin & some double chin although I’m underweight making my head & jaw too big in the photos.I’d like to get dental work done to address my misaligned jaw in the future.What’s the best combination of procedures that would give v shape to my face?
