Tooth busted off?

So I was eating some ribs and I think I hit a bone, turned out I also broked my tooth off at about a 45 degree angle. I just thought it was some bristle in the meat. I it broke off above the gum line so I guess that's good. You can't see it either when I smile. How do they fix this? Does it need to be fixed, or is it okay? I don't really care since it's not on the front to be honest. Is this a simple fix? I almost think this tooth was cracked in half for like the last year or so and I just never noticed until just now it busted off. lol It doesn't hurt, but does kind of feel like I have food stuck in my tooth. That's how I figured it out, was that I went over to the mirror to get whatever food was stuck to find out half the tooth was gone.
