Looks like solder to me. I can't imagine holding some solder (usually only ~40% lead) in your teeth would give you that much exposure to be an issue. But I suppose doing it all day, every day, for years could add up.

- louprado 12y agoLead vaporizes at 1749 °C. Not going to happen while soldering.
