Two broken teeth in Shimano 105 crankset
If it was mine and I damaged it riding, moving, storing etc. I would try to de-burr the edges and see how it shifted. In your case any modifications you make means you own it. Contact either the shipper or the vendor and forward the pictures to their claims dept. If you exhaust all avenues and are stuck with it, try repairing it then install it. If it works  to your satisfaction monitor it for premature wear. If the shifting seems less than optimal replace just the large ring and it should work like new one.
