Other alternative for gum line? (Photo)

Hi, I have a gummy smile that I am extremely self conscious about. I had braces in the middle school and at that time I was recommended to have jaw surgery on both of my jaws to have them essentially broken and reset. My parents decided not to go through with the surgery and instead I got spreader bar on the roof of my mouth to widen my top jaw. I am now looking for other options to correct my gummy smile that does not require jaw surgery as recommend by my dentis
