Amalgam Fillings

Repair Your Cavities

Amalgam fillings, also known as silver fillings, have been a popular choice for dental restorations for over a century. They’re a durable and cost-effective option for repairing cavities and restoring damaged teeth. While dental amalgam fillings aren’t used as widely with the advancement of technology and treatments, many patients may still have them.

Our Staten Island dentists break down amalgam fillings below. If you need to schedule an appointment with our team, call us today at (718) 948 5111. While we don’t offer amalgam fillings, we do offer composite dental fillings at our dental practice.

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 Benefits

There are various benefits to dental amalgam restorations, including:

• Durability: Amalgam fillings are exceptionally durable and can withstand chewing forces for many years, making them a long-lasting option.
• Cost-Effectiveness: They’re often more affordable than alternative dental restorations, making them accessible to a wide range of patients.
• Strength and Load-Bearing Capacity: Amalgam fillings are strong and can bear heavy chewing loads, making them suitable for molars and teeth subjected to significant pressure.
• Longevity: With proper care and maintenance, amalgam fillings can last for decades.
• Ease of Placement: Dentists find it relatively easy to place amalgam fillings, and the procedure is generally quicker than some alternatives.

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:

1. Cosmetic Concerns: Amalgam fillings are silver in color and can be more noticeable than tooth-colored composite fillings.
2. Fractures or Breakage: Over time, fillings can become worn, cracked, or broken.
3. Decay: If decay develops around or under an existing filling, it may need to be replaced.
4. 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.
