Lead Found In Dental Appliance

Lead Found In Dental Appliance

Finally! It’s been so long since we’ve posted about anything tainted with lead that we were starting to wonder if all the world’s trade problems had been resolved—but now comes a new study that found 210 parts per million (ppm) of lead in the porcelain veneer of a dental crown ordered from China. That’s a lot less than the CPSC’s current 600 ppm threshold, but a lot more than the international standard of only 90 ppm. The good news is it’s highly unlikely developing children will need a mouth full of crowns and bridges. The bad news is it’s yet another example of how hazardous material can slip undiscovered into the marketplace—and your mouth.
