Amalgam fillings, often referred to as silver fillings, have been a staple in dental restorations for over a century. Known for their durability and cost-effectiveness, amalgam fillings are used to repair cavities and restore tooth structure.

While we primarily offer composite fillings, we’re happy to discuss all your options to meet your dental needs.
What Are Amalgam Fillings?
Amalgam fillings are a type of dental restorative material used to treat cavities and repair damaged teeth. These dental fillings are composed of a blend of metals, including mercury, silver, tin, and copper. The unique combination creates a strong and durable material capable of withstanding chewing forces for years.
Composition of Dental Amalgam Fillings
- Mercury: ~50%
- Silver: 22-32%
- Tin: ~14%
- Copper: 8-12%
- Trace metals: Small amounts of zinc and other elements
Amalgam Filling Benefits
There are various benefits to dental amalgam restorations, including:
- Durability: Resistant to wear and pressure, making them ideal for molars and other load-bearing teeth.
- Cost-Effective: Amalgam fillings are often less expensive than alternatives like composite resin or ceramic fillings.
- Strength: Excellent for restoring teeth exposed to heavy chewing forces.
- Longevity: With proper care, they can last 10-15 years or longer.
- Quick Placement: The procedure is straightforward and often faster than placing composite fillings.
Amalgam Filling Disadvantages
Just like other dental treatments, there are certain disadvantages associated with an amalgam restoration, such as:
- Aesthetic Limitations: The silver color is noticeable and doesn’t match natural tooth enamel.
- Thermal Sensitivity: Amalgam can expand and contract with temperature changes, potentially leading to cracks in the tooth structure.
- Allergic Reactions: Rare, but some individuals may experience sensitivity to the metals used.
- Environmental Concerns: Amalgam contains mercury, which requires careful disposal to prevent harm to the environment.
Placing Amalgam Fillings
Preparation of the Tooth
The process begins with the removal of decayed or damaged tooth structure, followed by isolating the tooth to keep it dry. The tooth is then etched, and a bonding agent is applied to prepare it for the filling.
Mixing and Placement of Amalgam
Next, the dental amalgam material is mixed and then packed into the prepared cavity to ensure a secure fit.
Condensation and Carving
The amalgam is properly condensed to guarantee good adaptation to the tooth. It is then carved and shaped to resemble the natural tooth anatomy.
Final Polishing
Finally, the filling is smoothed and polished to minimize rough edges and enhance comfort for the patient.
Are Amalgam Fillings Safe?
The safety of amalgam fillings has been extensively studied. Here’s what you need to know:
- Mercury Content: Dental amalgam releases small amounts of mercury vapor, especially during chewing or brushing. However, these levels are well below the safety thresholds established by the American Dental Association (ADA), the World Health Organization (WHO), and other leading health organizations.
- Health Risks: For most patients, amalgam fillings pose no significant health risk. However, individuals with mercury sensitivities or certain medical conditions may benefit from alternative materials.
- Environmental Considerations: Dental offices use amalgam separators to manage waste safely, following Environmental Protection Agency (EPA) guidelines.
Replacing Dental Amalgam Fillings
Reasons for replacing amalgam fillings include:
- Cosmetic Preferences: Many patients opt for tooth-colored composite fillings for a more natural appearance.
- Wear and Tear: Cracked, broken, or leaking fillings should be replaced to protect tooth health.
- Decay: If new cavities develop around an existing filling, replacement may be necessary.
- Concerns About Mercury Exposure: While amalgam is considered safe, some patients choose alternatives for peace of mind.
Note: Removing amalgam fillings can temporarily release mercury vapor. Proper techniques are used to minimize exposure during removal.
Costs of Dental Amalgam Fillings
The cost of amalgam fillings typically ranges from $50 to $150 per tooth, depending on factors like:
- Size and location of the cavity
- Complexity of the procedure
- Dental practice location
Most dental insurance plans cover a significant portion of amalgam filling treatments.
