A friend of mine's dad scarpered from France via Dunkirk some decades ago, losing his false teeth somewhere on the beach. This really upset him, but fifty years later he was at a reunion in Dunkirk and they all had a fish supper in a seafood restaurant. My friend's dad sliced open his beautiful piece of fish and - guess what? - no sign of his teeth.
The moral is that the more you want it back the less likely it is to appear, so just steal someone else's.
