Back of front tooth chipped, no pain at all. What should I expect? (photos)

A few months ago, I chipped the back of my front tooth. It's not painful at all. The only reason it even bothers me is because I know it's there. I meant to go to the dentist but I have had terrible past experiences and didn't go out of fear. However, I do want to sort it out. It's just a small piece that came off and there is absolutely no pain or discomfort. What should I expect?
