Assuming that they are aware of the pregnancy, and in consultation with the patient, dentists may recommend alternative restorative materials, other forms of treatment, or delay of treatment. In many instances amalgam presents the best possible option for restorative material. There is no specific scientific evidence of ill effects although mercury is known to cross the placenta. Most children today have far fewer cavities than in the past, and, consequently, less exposure to mercury. Dentists give special consideration to restorative treatment for children and any concerns expressed by parents.
Dental amalgam offers distinct advantages in many cases.
Alternative materials are considered when suitable and recommended as indicated. There is a report on mercury exposure and risks from dental amalgam which was released by Health Canada on November 27, 1995. The assessment of mercury exposure and risks from dental amalgam conducted by G. Mark Richardson, PhD, is a review and analysis of the scientific literature by a scientist commissioned by Health Canada. The study involved no new research of the kind that CDA has been urging. It was a form of risk assessment using sophisticated mathematical techniques and computer modeling.
