What Can I Do About my Chin Implant Looking Unnatural?

I have a receding chin and had a chin implant. It does not look natural. Profile is good but the frontal view looks as if I have an egg/bump at the bottom of my face. Some doctors are saying that yes a person with a receding chin can have an implant due to all the shapes and sizes of implants available. What do I do in my case? It's the second implant and it does not look good? What can I do about the egg shape at the bottom of my face? Are fillers and option? What are my options?
