What Should I Know Before Getting a Dental Amalgam Filling?
Before getting a dental amalgam filling, you should know that it is a durable and cost-effective option made from a mixture of metals, including mercury, silver, tin, and copper. While it is strong and long-lasting, some patients prefer alternative materials like composite due to aesthetic concerns or potential mercury exposure, though the FDA and WHO consider it safe for most people.

What Are Dental Amalgam Fillings ?
Dental amalgam fillings are a common type of restorative material used to fill cavities caused by tooth decay. Made from a mixture of metals, including mercury, silver, tin, and copper, amalgam fillings are durable, strong, and cost-effective. They are particularly well-suited for molars and other back teeth due to their ability to withstand the significant pressure from chewing. Despite some concerns about mercury content, dental amalgam has been extensively used for over 150 years and is considered safe by dental and health organizations like the FDA and WHO.
Benefits of Dental Amalgam Fillings?
- Durability: Amalgam fillings can last 10-15 years or more with proper care, making them a reliable choice for long-term dental restoration.
- Strength: They can withstand significant chewing forces, which makes them ideal for molars and other teeth used for grinding food.
- Cost-Effective: Compared to other filling materials, amalgam is often more affordable, making it accessible to a wider range of patients.
- Proven Track Record: Amalgam fillings have been extensively studied and used worldwide for over 150 years.
- Less Sensitivity: Unlike composite fillings, amalgam is less sensitive to moisture during placement, ensuring a stronger bond even in challenging conditions.
- Quick Application: The procedure for placing an amalgam filling is generally faster and less technique-sensitive, making it a practical option for many patients.
Candidates for Dental Amalgam Fillings:
- Patients with Extensive Decay: Ideal for those needing durable fillings in larger cavities, especially in the back teeth.
- Patients on a Budget: Amalgam fillings are more cost-effective compared to other materials, making them suitable for patients seeking affordable options.
- Individuals Who Need Strong Fillings: Perfect for people who require fillings that can withstand heavy chewing forces, such as those with molar cavities.
- Patients Seeking Longevity: Suitable for those looking for long-lasting dental restorations, as amalgam can last 10-15 years or more with proper care.
At Amirad Family Dentistry, our skilled cosmetic dentist in Toronto provides amalgam fillings as a reliable option for patients seeking durable restorations for their teeth.
When Should You Use Amalgam Fillings?
Amalgam fillings are a durable and cost-effective solution, often recommended by dentists for specific situations. They are especially useful for large cavities or when strength and longevity are needed. Here are the main instances when amalgam fillings are commonly used:
- Large Cavities: Ideal for treating cavities that require a strong, long-lasting filling.
- Back Teeth: Best suited for molars and other teeth that experience significant chewing pressure.
- Cost-Effective Option: A more affordable choice compared to other materials like composite or gold fillings.
- Durability: Recommended for patients who need a filling that will last 10-15 years or longer.
- Moisture Resistance: Suitable for situations where the cavity is hard to keep dry during the procedure.
Potential Risks of Dental Amalgam Fillings
- Aesthetics: Amalgam fillings are not tooth-colored, which might be a concern for some patients who prioritize appearance.
- Mercury Content: Mercury, a key component of amalgam, raises concerns about potential health risks, though regulatory bodies have deemed it safe for use in dental applications.
- Sensitivity: Some patients may experience short-term sensitivity after receiving an amalgam filling.
When it comes to dental fillings, two common options are amalgam and composite fillings. Both serve the same purpose—restoring decayed or damaged teeth—but they differ in material, appearance, durability, and cost. Understanding their differences can help you make the best choice for your dental health.
Amalgam vs. Composite Fillings
When it comes to dental fillings, two common options are amalgam and composite fillings. Both serve the same purpose—restoring decayed or damaged teeth—but they differ in material, appearance, durability, and cost. Understanding their differences can help you make the best choice for your dental health.
Amalgam Fillings:
- Made from a mixture of metals, including silver, mercury, tin, and copper.
- Extremely durable and long-lasting (can last 10-15 years or more).
- More affordable compared to composite fillings.
- Highly resistant to wear and suitable for back teeth where chewing pressure is high.
- Noticeable silver color, making them less aesthetically pleasing.
- May expand and contract over time, potentially leading to cracks in the tooth.
Composite Fillings:
- Made from a tooth-colored resin that blends with natural teeth.
- Less durable than amalgam, lasting around 5-10 years.
- More expensive than amalgam fillings.
- Bonds directly to the tooth, preserving more natural structure.
- Can be used for front and back teeth but may wear down faster in high-pressure areas.
- Requires more time to apply and may need replacement sooner.
Amalgam vs. Composite Fillings: Which One Is Right for You?
The best choice depends on your needs and priorities. If you prioritize durability and cost, amalgam fillings may be the better option, especially for molars that endure heavy chewing. However, if aesthetics and preserving tooth structure matter more, composite fillings are ideal, particularly for visible teeth. Consulting your dentist in Toronto will help determine the most suitable filling for your specific case.
How Long Do Amalgam Fillings Last?
Amalgam fillings are known for their durability and can last anywhere between 10 to 15 years, sometimes even longer with proper oral care. Their strong metal composition makes them highly resistant to wear and chewing pressure, especially in molars. However, factors like teeth grinding, poor oral hygiene, and natural wear over time can affect their lifespan, making regular dental check-ups essential for monitoring their condition.
Are Amalgam Fillings Safe?
Yes, amalgam fillings are generally considered safe by major health organizations, including the American Dental Association (ADA) and the U.S. Food and Drug Administration (FDA). While they contain mercury, it is bound with other metals, making it stable and unlikely to cause harm. Extensive research has found no proven link between amalgam fillings and health problems in most people. However, certain groups, such as pregnant women and individuals with mercury allergies, may be advised to consider alternative materials. At Amirad Dental Clinic, our experienced dentists prioritize patient safety and can help you choose the best filling material based on your individual needs and concerns. If you have any questions about amalgam fillings, our team is here to provide expert guidance.
Can You Replace Amalgam Fillings?
Yes, amalgam fillings can be replaced with other types of fillings. Many patients choose to replace amalgam fillings with composite resin fillings, porcelain, or gold fillings for aesthetic reasons, as these materials match the natural color of the teeth better than silver-colored amalgam. Additionally, some people may want to replace amalgam fillings due to concerns about the mercury content in the material, though research has shown that amalgam is considered safe for most people.
The process of replacing an amalgam filling typically involves:
- Assessment: The dentist will assess the condition of the existing filling and the surrounding tooth structure.
- Removal: The old amalgam filling is carefully removed, and any decay is cleaned out.
- Preparation: The tooth is prepared to receive the new filling, ensuring a good fit and bond.
- Placement: The new filling material (such as composite resin) is placed and shaped to match the natural contours of the tooth.
- Curing: If using composite resin, the material is hardened using a special light.
If you’re considering replacing your amalgam fillings, it’s best to consult with a dentist to discuss your options and determine the best course of action for your oral health.

Why Is Mercury Used in Dental Amalgam?
Mercury is a critical component of dental amalgam because it binds the other metals together, creating a strong, durable, and malleable material that can be easily placed and shaped inside the tooth. Once the amalgam hardens, the mercury is chemically bound and considered stable. Regulatory agencies, including the World Health Organization (WHO), confirm that amalgam is safe for most patients when used appropriately.
What Is Bioaccumulation?
Bioaccumulation refers to the gradual accumulation of substances, such as heavy metals, in an organism over time. Mercury is one such substance that can bioaccumulate in the body if exposure occurs consistently. However, the mercury used in dental amalgam has been shown to release only minimal amounts over time, typically far below harmful levels. Concerns about bioaccumulation are more relevant to mercury exposure through other environmental or dietary sources.
Why Are Amalgam Fillings Still Used?
Amalgam fillings are still used primarily because of their durability, affordability, and long history of effectiveness. The material is strong and resistant to wear, making it ideal for large fillings in back teeth that endure significant pressure from chewing. Amalgam is also relatively easy and quick for dentists to place, and it tends to be more cost-effective than other filling options. Despite concerns about its appearance and the mercury content, it remains a reliable and widely used option, particularly for patients who prioritize strength and longevity over aesthetics.
The Cost of Amalgam Fillings in Toronto
When considering the cost of dental amalgam fillings, it’s important to choose a dental practice that offers high-quality care. Amirad Family Dentistry in Toronto provides expert services, ensuring that patients receive durable and reliable amalgam fillings. The amalgam fillings cost in Toronto can vary depending on factors such as the size of the filling and the complexity of the procedure, but at Amirad Family Dentistry, patients can be confident they are receiving top-notch treatment with a focus on long-term oral health.
Here’s a table comparing different types of dental fillings based on their cost and other characteristics:
| Type of Dental Filling | Cost Comparison | Durability | Aesthetic Appeal | Common Use |
|---|---|---|---|---|
| Amalgam | Low | Very High | Low | Back teeth, large cavities |
| Composite Resin | Medium | Medium | High | Front teeth, visible areas |
| Porcelain | High | High | Very High | Front teeth, aesthetic focus |
| Gold | High | Very High | Low | Back teeth, long-lasting |
| Glass Ionomer | Medium | Medium | Low to Medium | Fillings for baby teeth or areas with less chewing pressure |
This table highlights the relative cost, durability, aesthetic appeal, and common uses of various types of dental fillings.
Amalgam Fillings and Sensitivity
Amalgam fillings are generally considered to be durable and long-lasting, but some individuals may experience sensitivity after getting them placed. Sensitivity can occur due to various reasons, such as the filling being placed too close to the nerve of the tooth or the process of removing decay before placing the filling. Some people may also experience sensitivity to hot or cold temperatures in the treated tooth. However, this sensitivity is usually temporary and should subside as the tooth heals. If sensitivity persists or is particularly uncomfortable, it’s important to consult with a dentist, as it could indicate an issue with the filling’s fit or a need for further adjustment.
Amalgam Filling Removal
Amalgam filling removal is not always necessary for your oral health unless the filling is damaged, deteriorating, or causing discomfort. While some people choose to replace amalgam fillings for cosmetic reasons or due to concerns about mercury content, dental experts generally agree that amalgam is safe and effective for most patients. However, if an amalgam filling is cracked, leaking, or causing tooth sensitivity, removal and replacement with a different material, such as composite resin, may be recommended. It’s important to consult with your dentist to evaluate the condition of your fillings and determine the best course of action for your overall oral health.
Should I Remove My Amalgam Fillings if I’m Concerned About Mercury?
Removing amalgam fillings is not typically recommended unless they are damaged or there is a specific medical reason to do so. Removal involves drilling, which can temporarily increase mercury exposure. At Amirad Dental Clinic, we advise patients to consult with our experienced dentists to assess whether removal is necessary. If your fillings are intact and not causing any issues, it’s usually best to leave them in place.

Who are not candidates for dental amalgam fillings?
Certain groups may be advised to avoid dental amalgam due to potential risks:
- Pregnant and Nursing Women: While no conclusive evidence shows harm, alternatives may be considered to minimize potential mercury exposure.
- Children Under Six: Developing bodies may be more sensitive to any environmental mercury exposure.
- Patients with Mercury Allergies: Though rare, some individuals may have a true allergy to mercury or other metals in the amalgam.
At Amirad Dental Clinic, we discuss all available options with patients from these groups and recommend alternative materials such as composite fillings when appropriate.

Is a Broken Amalgam Filling Dangerous?
A broken amalgam filling can pose risks, as it may:
- Expose the Tooth to Decay: The gap left by a broken filling can allow bacteria to accumulate, leading to further decay.
- Release Mercury: When damaged, an amalgam filling might release small amounts of mercury vapor.
