Places that buy dental gold?

I suppose this is a long shot, but are there any jewelry stores around Taipei that buy old dental crowns and the like, paying money for the gold alloy therein? There are places in the US, but I wonder whether it might run against some cultural taboo in Taiwan.

you need to find a smelter, and I have no idea where one would be in Taipei. I use to do the dental to bars with my brother in NY/NJ area.
If you do go to a smelter, insist that you watch the entire process of them making it into a gold bar, never leave the room or turn your back from the gold bar…as they can cheat you buy adding copper or other cheaper metals to the bar, and then later when they drill it for the value they can drill at those locations and rip you off from the true value of your gold.
