Amalgam Fillings: What You Need to Know
If you’ve ever needed a dental filling, you may have heard about amalgam fillings. These are silver-colored fillings made from a mix of metals, including silver, tin, and mercury. For years, amalgam fillings have been a go-to option because of their strength and durability. At Genesis Dental, our experienced dentist in Flower Mound, TX, Dr. Madeleine Zhao and her team often use these fillings to treat cavities, helping patients from the surrounding areas maintain their oral health.
Amalgam fillings are especially useful for back teeth because they can withstand the pressure from chewing. If you’re wondering whether amalgam fillings are the right choice for you, Dr. Zhao can help you weigh the benefits and discuss alternative options.

What Are Amalgam Fillings?
Amalgam fillings are restorations used to repair cavities, tooth decay, and damaged teeth. They consist of a mixture of metals, primarily mercury, silver, tin, and copper. This mixture forms a strong and durable filling material that can withstand the rigors of chewing and lasts for many years.
Composition of Dental Amalgam Fillings
- Mercury (approximately 50%)
- Silver (approximately 22 to 32%)
- Tin (approximately 14%)
- Copper (approximately 8 to 12%)
- Trace amounts of other metals
Amalgam Filling Disadvantages
Just like other dental treatments, there are certain disadvantages associated with an amalgam restoration, such as:
- Aesthetic Concerns: One of the primary drawbacks of amalgam fillings is their silver color, which is conspicuous in the mouth and may be considered unattractive.
- Expansion and Contraction: Amalgam fillings can expand and contract with temperature changes, potentially leading to tooth fractures or leakage over time.
- Allergic Reactions: Some individuals may have allergic reactions or sensitivities to the metals used in amalgam fillings, although such cases are rare.
- Environmental Concerns: Amalgam fillings contain mercury, which can be harmful to the environment if not disposed of properly.
Placing Amalgam Fillings
Preparation of the Tooth
- Removal of decayed or damaged tooth structure
- Tooth isolation to keep it dry
- Tooth etching and application of bonding agent
Mixing and Placement of Amalgam
- Mixing the dental amalgam material
- Packing the mixture into the prepared cavity
Condensation and Carving
- Properly condensing the amalgam to ensure good adaptation
- Carving and shaping the filling to resemble the natural tooth anatomy
Final Polishing
- Smoothing and polishing the filling to minimize rough edges and enhance comfort
Costs of Dental Amalgam Fillings
Patients can expect to spend between $50 to $150 for a single amalgam filling. However, each case is unique and will fluctuate based on certain factors including the size and location of the cavity and the location of the dental practice. In most cases, dental insurance covers a portion of dental filling treatments.
Are Amalgam Fillings Safe?
The safety of dental amalgam and its mercury content has been a topic of debate for many years. Here are some insights to consider:
- Mercury Release: Dental amalgam fillings release small amounts of mercury vapor over time, especially during chewing or brushing. However, the amount released is very low.
- Exposure Levels: Numerous studies have measured the mercury concentrations in the bodies of people with amalgam fillings. While having amalgam fillings can result in increased mercury levels in the body, these levels are generally considered to be well below safety thresholds set by major health organizations.
- Exceptions: Some individuals may be more sensitive to the effects of mercury or may have allergic reactions to components of the amalgam. In such rare cases, an alternative filling material might be recommended.
Replacing Dental Amalgam Fillings
Dental amalgam fillings can be replaced for various reasons, including:
- Cosmetic Concerns: Amalgam fillings are silver in color and can be more noticeable than tooth-colored composite fillings.
- Fractures or Breakage: Over time, fillings can become worn, cracked, or broken.
- Decay: If decay develops around or under an existing filling, it may need to be replaced.
- Concerns About Mercury: While the American Dental Association and numerous other health organizations consider amalgam fillings safe, some people choose to have them replaced due to concerns about mercury exposure. However, removing an amalgam filling can temporarily increase exposure to mercury vapor released during the process.
