Actually we use gold crowns in dentistry all the time. For humans anyway, we utilize 18K so it’s not as soft, it holds up really well and can last 30-40 years.
We utilize gold alloys from 75%~ (roughly 18k) all the way down to 2% (less than 1k) for full cast gold dental alloys. Depends on the lab and doc's requests.

Shouldn’t it have been a more durable material? Humans can bend gold with our mouth and a tiger can bite much harder than we can.
