What is a composite filling?
Composite fillings are fabricated with a mixture of glass or quartz and resin, resulting in a natural tooth-colored material. They are extremely durable when bonded to the tooth with adhesive.
What is an amalgam filling?
Amalgam fillings, often referred to as “silver fillings,” are made from a blend of mercury (about 50%) and other metals such as silver, tin, and copper. Mercury helps bind the metals together to create a strong and lasting material. Amalgam has been used in dentistry since 1895 to fill cavities.
Are amalgam fillings dangerous?
Concerns have circulated about the safety of mercury in amalgam fillings. However, major medical and scientific organizations—including the American Dental Association, U.S. Food and Drug Administration, Mayo Clinic, and the National Multiple Sclerosis Society—support the safety of dental amalgam.
The International Journal of Dentistry concluded:
- Mercury from dental amalgam does not contribute to systemic disease or toxic effects
- Allergic reactions to mercury are extremely rare
- Current data does not support discontinuing the use of amalgam in clinical dentistry

Tip: If you’re concerned about your child’s amalgam fillings, a consultation with your dentist can help you feel more confident in your options.
Is a composite filling the same as a white filling?
Yes! The term “white filling” is commonly used to describe composite fillings. These fillings are color-matched to your natural teeth and typically appear white, off-white, or slightly gray/yellow based on your tooth shade.
What’s the difference between composite and amalgam fillings?
Composite fillings blend in with your teeth, making them ideal for visible areas.
Amalgam fillings are metallic and more noticeable, but may be considered for large cavities in molars due to their strength and longevity.
Are amalgam fillings still used?
Yes, some dentists continue to use amalgam fillings when they’re the best option for a particular case. In some instances, insurance or Medicaid plans may only cover amalgam fillings, not composite ones.
