Silver Fillings or Tooth Colored Fillings
Posted on 11/15/2025 by Singing River Dentistry - Athens |
 Choosing the right material to repair a cavity can feel overwhelming. You might be asking yourself: What are my options? What are the pros and cons of each? It's a common question, and understanding the differences between "silver" (amalgam) and tooth-colored (composite) fillings is important for making an informed decision about your dental health. Let's explore these two popular filling types.
What Are Silver Fillings?
"Silver" fillings, also known as amalgam fillings, have been used for over a century to repair teeth damaged by decay. They are made from a mixture of metals, including silver, mercury, tin, and copper. The term "silver" is a bit misleading, as they appear more of a dull silver color.
What Are Tooth-Colored Fillings?
Tooth-colored fillings, also called composite fillings, are made from a resin and glass mixture that can be matched to the natural shade of your teeth. This makes them a popular choice for those concerned about the appearance of their smile.
Durability and Longevity
Amalgam fillings are known for their strength and durability. They can withstand significant chewing forces and often last for many years, sometimes even decades. Composite fillings are also quite durable, though they may not last as long as amalgam fillings in areas that experience heavy biting pressure, particularly with people who grind their teeth.
Aesthetic Considerations
The most obvious difference between the two is their appearance. Composite fillings blend seamlessly with your natural tooth, making them virtually invisible. This is a major advantage for fillings in visible areas of your mouth. Amalgam fillings, on the other hand, have a distinct metallic appearance, which can be noticeable, especially in larger fillings or in teeth towards the front of your mouth.
Safety Considerations
There has been ongoing discussion about the safety of amalgam fillings due to their mercury content. The American Dental Association and other leading health organizations have stated that amalgam fillings are safe for both adults and children. The mercury in amalgam is bound to the other metals, making it stable and preventing it from being released in harmful amounts. Composite fillings are considered biocompatible and do not contain mercury.
Placement and Procedure
Both types of fillings require the dentist to remove the decayed portion of the tooth. With composite fillings, the tooth surface needs to be kept extremely dry during placement, which can sometimes be a bit more time-consuming than placing an amalgam filling. Composite fillings are bonded directly to the tooth structure, which can help strengthen the tooth. Amalgam fillings are packed into the prepared cavity.
Cost Factors
Generally, composite fillings are slightly more than amalgam fillings. The difference in price reflects the cost of the materials and the time required for placement.
Making the Right Choice
The best type of filling for you depends on several factors, including the location and size of the cavity, your aesthetic preferences, your bite, and your budget. Discuss your options with your dentist. They can help you weigh the pros and cons of each type of filling and recommend the most suitable choice for your individual needs. Your dentist is your partner in achieving and maintaining a healthy, beautiful smile!
