Cavity Repair Solutions at Tacoma Dental Office
Dental amalgam fillings, commonly known as silver fillings, have been a trusted dental restorative material for over a century. While modern dentistry has evolved toward tooth-colored alternatives, many patients still have amalgam restorations or may have questions about these traditional dental fillings.
Our Tacoma, WA, dentist provides this comprehensive guide to help you understand amalgam fillings and the alternatives we offer. For personalized dental treatment recommendations or to schedule regular dental checkups, contact our Tacoma dental practice today at (253) 761-5422.
What Are Dental Amalgam Fillings?
Dental amalgam is a durable filling material used to repair tooth decay and restore damaged tooth structure. Traditional amalgam fillings consist of a precise mixture of metals that creates a strong, long-lasting dental restoration capable of withstanding significant chewing forces.
Composition of Dental Amalgam Alloy
- Mercury (approximately 50%): combined with alloy powder to form dental amalgam
- Silver (approximately 22-32%)
- Tin (approximately 14%)
- Copper (approximately 8-12%, higher in high copper alloys)
- Trace amounts of other metals
According to the American Dental Association and extensive dental research, properly placed amalgam restorations remain a safe and effective option for many patients, particularly for adult posterior teeth that endure heavy chewing loads.
Benefits of Dental Amalgam Restorations
Patients considering their options for dental fillings should be aware of these advantages:
- Exceptional Durability: Amalgam restorations typically withstand chewing forces for 10-15 years or longer with proper care
- Cost-Effectiveness: Generally more affordable than alternative dental materials, making them accessible for many patients
- Superior Strength: Excellent load-bearing capacity makes them suitable for molars and teeth subjected to significant pressure
- Proven Longevity: With regular dental checkups and good oral hygiene, amalgam fillings can last for decades
- Efficient Placement: The dental treatment process is typically quicker than some alternatives, reducing chair time
Amalgam Filling Disadvantages
Just like other dental treatments, amalgam fillings do have certain limitations:
- Aesthetic Concerns: The silver filling appearance is noticeable, particularly in visible areas of the mouth
- Thermal Expansion: Amalgam can expand and contract with temperature changes, potentially affecting surrounding tooth structure over time
- Mercury Considerations: Dental amalgam contains elemental mercury that releases low levels of mercury vapor, particularly during the removal process
- Environmental Impact: Proper handling of amalgam waste through amalgam separators is crucial for environmental protection, as regulated by the Environmental Protection Agency
- Rare Allergic Reactions: Some individuals may develop oral lesions or experience heightened sensitivity to components in the amalgam alloy
Placing Amalgam Fillings
The placement of amalgam fillings involves key steps for successful dental restoration. First, the dentist removes decayed or damaged tooth structure and keeps the tooth dry. The dental amalgam material is then mixed and packed into the cavity with precision.
It’s condensed, carved, and shaped to match the natural tooth anatomy. Finally, the filling is smoothed and polished to enhance comfort and durability, ensuring it withstands chewing forces while maintaining tooth integrity.
Mercury in Dental Amalgam: Safety Considerations
The safety of mercury in dental amalgam has been thoroughly evaluated by numerous health organizations, including the World Health Organization and the Centers for Disease Control. Current scientific consensus indicates:
- Mercury Vapor Released: Dental amalgam fillings release small amounts of inorganic mercury vapor, particularly during placement or removal
- Mercury Exposure Levels: Studies measuring mercury levels in people with amalgam fillings show these levels generally remain well below safety thresholds
- Special Considerations: Certain groups may require additional assessment, including pregnant women (due to potential concerns for developing fetuses), individuals with impaired kidney function, or those with pre-existing neurological disease
- Mercury Toxicity Prevention: Dental professionals follow strict protocols when mixing liquid mercury with alloy particles and when removing amalgam fillings to minimize exposure to toxic substances
Modern Alternatives: Direct Composite Resin Fillings
At our Tacoma dental practice, we offer advanced tooth-colored alternatives to amalgam:
- Natural Appearance: Composite resin fillings can be precisely matched to your natural tooth color
- Conservative Approach: Requires less removal of healthy tooth structure
- Mercury-Free Option: Contains no elemental mercury or other metals, eliminating concerns about mercury toxicity
- Bonding Technology: Directly bonds to the tooth structure, potentially strengthening the remaining tooth
The Cost of Dental Fillings in Tacoma
While amalgam fillings traditionally cost between $50 and $150 per tooth, our dental practice offers competitive pricing on modern composite alternatives. Each treatment plan is customized based on:
- Size and location of the cavity or decay beneath existing fillings
- Number of surfaces requiring restoration
- Your specific dental insurance coverage
Most dental offices, including ours, work with insurance providers to maximize your benefits. Our dental team can help you understand your coverage for both new fillings and replacing amalgam fillings with tooth-colored alternatives.
Should You Replace Your Amalgam Fillings?
Considerations for replacing existing amalgam fillings include:
- Visible decay around the restoration
- Cracks or damage to the filling or surrounding tooth
- Aesthetic concerns about silver fillings in visible areas
- Personal preference for mercury-free dental materials
It’s important to note that the removal process of amalgam must be performed with proper protocols to minimize mercury vapor released during the procedure. Our dental professionals are trained in safe amalgam removal techniques.
