But you also have the cost of man hours, marketing that you buy gold, finding a smelter that will take teeth, or do it yourself. That’s not all profit, plus you don’t know the gold weight until you remove it from the tooth. Which is risk. Plus it’s possibly a biohazard.

These people buy millions per day in gold, I’m sure if it was profitable they wouldn’t turn it away.

You can try it though, go to all the gold stores in your area and tell them you’ll buy all the teeth they bring in.
