Dental crowns and bridges have been used safely and effectively for many years. The Arizona Dental Association encourages patients to request information from their dentist regarding the origins of their crown or bridge.
The American Dental Association, the parent organization to AzDA, asked the U.S. Centers for Disease Control and Prevention (CDC) if there were any safety concerns about lead in dental crowns and bridges, particularly those that are fabricated overseas. The CDC's response stated that trace amounts of lead are "extremely unlikely to cause adverse health effects." The CDC also stated that given the current information at hand, they do not recommend that individuals defer needed dental treatment or have existing dental crowns, bridges or other prostheses removed.
The American Dental Association is presently conducting random tests of dental crowns made in the U.S. and in other countries to determine how much lead they may contain and if any lead could be released. The ADA will share its research findings with the public, the dental profession and the appropriate regulatory agencies. Preliminary results have not shown excessive lead levels.
