Amalgam is an economical blend of metals used to fill cavities in the mouth. Also known as ‘silver fillings’, amalgam fillings are comprised of silver, copper, mercury and tin. The majority of Americans have dental fillings – most of whom have at least one amalgam. Many prefer amalgam because it is the most affordable and long-lasting filling material available today. In fact, amalgam fillings are less likely to fall out or break than other filling material.
Frequently Asked Questions
Am I a candidate for amalgam fillings?
Nearly anyone with tooth cavities over the age of 6 is a candidate for amalgam fillings. However, the decision to get silver fillings can only be made between you and your dentist. Be sure to tell your dentist if you have any metal allergies from getting an amalgam filling.
What should I expect when I get my amalgam filling?
Your dentist will numb the nerves surrounding your tooth at the start of your visit. Then, your tooth will be prepped to remove decay and prepare the surface for your filling. Amalgam is mixed at the time of filling using a combination of metal alloy and liquid mercury. Blended together, these ingredients make a putty that hardens and typically requires no follow-up visit. The mercury concentration is removed during the polishing phase.
How long will an amalgam filling last?
Amalgam fillings are made to withstand biting pressure and last for many years. Instances of breakage are rare, and repair frequency is low. When properly cared for, most silver fillings last a minimum of 10 to 15 years. Your dentist will check the condition of your fillings during your periodic dental exams and cleanings.
