In February, the FDA said it was considering a ban on certain types of cement used for dentistry.
Some of the cement, called dental temporary concrete, is made from a common chemical found in sewage sludge, and is believed to cause dental caries and tooth decay.
Others, known as lehigh cement, are a synthetic form of cement.
In the meantime, the Food and Drug Administration (FDA) has warned against using any type of cement that contains lead or other metals, or that may contain solvents that can harm people.
The FDA has also said that certain cement products can also contain chemicals linked to the growth of mold and other problems.
Health Canada said that there is no scientific evidence linking the use of dental temporary-concrete cement to caries, but said that consumers should be aware of the potential health risks.
While the FDA has not yet issued a ban, the agency is looking into the potential risks of using the material in dental practices.
In response to the FDA announcement, the Association of Health Products Manufacturers (AHPMA) said that its members are “deeply concerned” about the use and possible impact on consumers.
The AHPMA has also called on the FDA to review the material.
According to the AHPM, lehigh-cement cement has been linked to significant health effects, including caries.
It has been used in dentistry since the 1930s, and has been found in consumer products since about 1995.
Health officials said that the FDA had not been able to find a way to safely remove the material from dental practices, and that it was time for the agency to move on.
A spokesperson for the FDA told CBC News that it had “strong concerns” about lehigh concrete and would be investigating its use in dental settings.
