What is the cause of my jaw asymmetry, and what are my options? (Photo)

There is a massive difference between the right side of my jaw and the left side of my jaw. One side is shorter than the other. I think it is due to hypodontia. I have been missing a second molar tooth on the bottom since birth and I think that this is the cause. Thie is because my missing tooth has been on the weaker side. As a result, my teeth have drifted and are extremely gapped. Will bone grafts and a dental implant to replace the missing tooth help or not? If not, what else can I do?
