Lip Shorter On One Side, What To Do? (photo)

Hello, about 5-6 years ago my dentist pointed out to me that my lip is shorter on the right side. Since then, I've looked through baby photos but they all showed normal symmetrical lips. I think this asymmetry only began to develop as I grew older. It's clearer if you take a look at the photo(it is my right and your left in photos). What can I do for this? I notice that my midline is off by 1 to 2mm for the bottom set of teeth. Please help! I don't think a midline correction can fix this.
