Toilet flange question

I'm replacing a toilet in our master bathroom, and upon removing the old toilet, the closet flange appears to have been intentionally bent. The sides where the bolts went in are sitting on top of the tile floor, but the front and back are bent down so they are flush with the tiles (they also appear to have been grouted to the tiles). This seems to be a copper flange, and the drain pipe is cast iron. House was built in 1986. The subfloor seems fine and the flange is securely fastened down and seems undamaged aside from the bend.

Is this something I can just install a wax ring on and be good to go, or should I repair/replace it? I'm not confident doing significant plumbing, so if it were replacement, I'll end up calling a plumber.
