31 years old. At around 17 while playing football a helmet hit under my face mask & injured my chin. What do I do? (Photos)

I believe it was broken, and actually a small piece of bone was dislodged and placed on the other side. It seems you can actually feel the foreign piece of bone there though it will not move nor now years later hurts at all. There was no jaw injury. If this is the case what can be done about this. I don't want any type of filler I do not believe. Maybe just grind the piece of bone out of there? Any help would help. Thanks
