I slightly chipped my front tooth when I bit on a metal key-holder. Are there any non-invasive repair options for this? (Photo)

Hi Docs, I slightly chipped my front tooth when I ignorantly bit on a metal key-holder. The chip is very slight. People barely notice it but I believe it can be seen if they pay close attention or stare at my teeth when I talk. I notice it all the time when I look in the mirror and when I brush my tongue through. It really disturbs me. I would really love a very non-invasive repair like maybe smoothening the edges till it is even but I don't know if that would work. I seek expert opinion.
