5 Questions to Ask Before Getting Dental Work

Lead May Poison Crowns, Bridges, Veneers or Dentures

By Dan Shapley

An Ohio woman became ill because Chinese-made crown was laced with lead, a potent toxic metal, according to an ongoing investigation by 10TV News in Central Ohio.

As much as 20% of the crowns, bridges, veneers, dentures and other dental fixtures used by U.S. dentists are made in China or other foreign countries, according to Newsday. Like other imports, fewer than 1% of dental products are inspected by the Food and Drug Administration, so there's effectively no cop on this beat. The American Dental Association, at least, is investigating.

The ADA recommends asking these questions before having work done:

1. Do you fashion your own crowns, bridges and other dental materials in the office or buy them from a dental lab?

2. Where is the dental lab located?

3. Does the lab outsource crowns or bridges to a foreign country?

4. What materials are going to be used in my restoration?

5. What other options do I have?
