Cavities Have a Silver Lining

Detroit, MI.

Another 20-something-year-old stubs out his cigarette and enters the dentist for a cavity filling appointment. The amalgam used to fill his cavity has a silver lining, though. Literally. The paste employs silver alloyed with mercury (and small amounts of other, less electrically and thermally conductive metals). It stiffens in minutes, hardens in hours, and will keep you more silver than most people's silverware, which is actually just cutlery made of other metals.

There is a silver lining, even to cavities. You just have to look where silverware meets silver.
