The regulation classifies dental amalgam into Class II (moderate risk). By classifying a device into Class II, the FDA can impose special controls (in addition to general controls such as good manufacturing practices that apply to all medical devices regardless of risk) to provide reasonable assurance of the safety and effectiveness of the device.
Specifically, the FDA recommended that the product labeling include:
- A warning against the use of dental amalgam in patients with mercury allergy;
- A warning that dental professionals use adequate ventilation when handling dental amalgam;
- A statement discussing the scientific evidence on the benefits and risk of dental amalgam, including the risks of inhaled mercury vapor. The statement will help dentists and patients make informed decisions about the use of dental amalgam.
