What surgeries can I take when I'm 18 to fix my uneven smile caused my a scar that left a "dimple" on the right side of my face?

When I was 8 I fell on the edge of a staircase step. In the hospital, I got stitches. I had bandages but didn't put the cream on regularly. Once the bandages came off I noticed that on the right side of my face (where the scar was) was a dimple/indent. It shows when I laugh/ smile with my teeth. When I smile with my lips, the dimple doesn't show but the smile on my right side is longer/higher than my left. I feel self conscious about it. What kind of surgery can I get/ will any surgery fix it?
