Dental fillings are a widely used dental treatment procedure and are made from metals like silver, gold, copper, nickel, or other composite resins. It is important to know what dental fillings are and one of the most common questions people have about them. But even though you might be curious about this subject, you might be unsure about how to find the answer to your own question.
What is a Dental Filling?
Dental fillings are small amounts of material placed into a cavity in your tooth to restore its structure or to fill in space that has been created by decay or trauma. Fillings are made of a variety of materials, including metals, resins, and glass. They are often colored to match your teeth and can be designed to resemble natural teeth.

Types of Dental Fillings
There are three different types of dental fillings: amalgam, gold, and silver. All three have their own benefits and drawbacks. Here is a closer look at each type:
Amalgam: Amalgam is a mixture of mercury and other metals that has been used in dental fillings for over 100 years. It is considered to be the best overall filling material because it is biocompatible (able to integrate with the surrounding tissues) and durable. However, amalgam fillings can release mercury over time, which can cause health problems.
Gold: Gold fillings are made of gold particles that are bonded to a resin. They are less likely to release mercury than amalgam fillings, but they are more expensive and less common than silver or amalgam fillings. Gold fillings tend to last longer than silver or amalgam fillings, but they may need to be replaced sooner due to wear and tear.
Silver: Silver fillings are made of small silver particles that are bonded to a resin. They are less likely to release mercury than gold fillings, but they may require more frequent replacement due to wear and tear.
