Can I get a natural smile back? Why does this happen abnormal look come all of a sudden?

After a year of wearing braces, the doctors suggested me to have a smile correction done and 4 of my premolars were removed as they were too strong..A year after removal of my braces, I can find my smile artificially lopsided..I have a problem while posing for pictures.Also, I can see a small depression in the left part of my smile line..
