Dental amalgams can be used for patients of all ages, in small or moderately-sized cavities in teeth, as a foundation for metal-ceramic or cast-metal restorations, when the tooth structure is severely destroyed, when the patient has poor commitment to oral hygiene, when the patient has a problem with moisture control, and when cost overrides patient concern.

Dental amalgams should not be used for restorations of anterior teeth, in root canals, when the patient has a history of allergy to amalgam components like mercury, and when a major restoration is needed and other restorative options is cannot be taken.
