| Health Canada’s Recommendations Concerning
the Use of Dental Amalgam (Health Canada, 1996a)
1. Non-mercury
filling materials should be considered for restoring the primary
teeth of children where the mechanical properties of the material
are suitable.
2. Whenever possible, amalgam fillings should not be placed in
or removed from the teeth of pregnant women.
3. Amalgam should not be placed in patients with impaired kidney
function.
4. In placing and removing amalgam fillings, dentists should use
techniques and equipment to minimize the exposure of the patient
and ;the dentist to mercury vapour, and to prevent amalgam waste
from being flushed into municipal sewage systems.
5. Dentists should advise individuals who may have allergic hypersensitivity
to mercury to avoid the use of amalgam. In patients who have developed
hypersensitivity to amalgam, existing amalgam restorations should
be replaced with another material where this is recommended by a
physician.
6. New amalgam fillings should not be placed in contact with existing
metal devices in the mouth, such as braces.
7. Dentists should provide their patients with sufficient information
to make an informed choice regarding the material used to fill their
teeth, including information on the risks and benefits of the material
and suitable alternatives.
8. Dentists should acknowledge the patient’s right to decline
treatment with any dental material.
