I craft crowns of gold and bridges of silver. Who am I?

Why this works

This riddle cleverly plays on the terminology used in dentistry. "Crowns of gold" refers to dental crowns made from gold, which dentists use to restore damaged teeth, while "bridges of silver" alludes to dental bridges that can be made from silver-colored materials, like alloys or porcelain. The use of royal and architectural imagery creates a whimsical connection between a dentist's work and the crafting of valuable items, making the answer both surprising and fitting!
