Exploring Dental Amalgam: Everything You Need to Know
Over 100 million North Americans have mercury-based fillings in their teeth. This number is more than Canada’s entire population. These fillings have been used for over a century, sparking debates and curiosity.
At Apple Wellness Dental in Airdrie, we mix old and new. Our team has put in thousands of silver-colored fillings. They last longer than many other options, thanks to their strength.
French dentists first used mercury-silver mixtures in 1826. They made a cost-effective option that’s lasted for years. Today, we use advanced technology to make these fillings safer and more stable.
Health Canada allows these fillings for back teeth, where they need to be very strong. Our clinic follows strict IAOMT protocols for placing or removing these fillings. We always put our patients’ safety first.

What Is Dental Amalgam
Dental amalgam is a mercury-based alloy used by dentists everywhere. It’s known for its strength in tough environments. This silver material has been a reliable choice for fixing teeth for over a century. At Apple Wellness Dental in Airdrie, we decide if it’s the best option for our patients.
Defining This Traditional Dental Material
Dental amalgam is made from metals to create strong fillings. It usually has:
- Liquid mercury (about 50%)
- Silver powder (30-35%)
- Smaller amounts of tin, copper, and zinc
Historical Use in Dentistry
Dentists started using amalgam fillings in the 1830s. For 150 years, it was the top choice for filling cavities. It was affordable, easy to use in moist environments, and lasted long in chewing surfaces.
Current Applications at Apple Wellness Dental
Even though composite resins are common today, we use amalgam fillings in certain cases:
- Large cavities in back molars
- Patients needing cost-effective solutions
- Areas requiring extreme durability
We follow Health Canada guidelines to ensure patient safety. We only suggest amalgam when it’s the best choice. For personalized advice, call our Airdrie team at (587) 332-6767.
Dental Amalgam Composition Breakdown
Dental amalgam is a mix of metals that has been used for over 150 years. It’s known for its durability. This makes it a reliable choice for fillings, even with newer options available.
Metallic Components and Ratios
A dental amalgam mix has four main parts. Health Canada and safety sheets guide these:
- Mercury (43-54%) – Makes it soft and easy to shape
- Silver (20-35%) – Adds strength and fights corrosion
- Tin (12-18%) – Helps it set tightly
- Copper (6-13%) – Makes it last longer in tough spots
While the exact amounts can vary, mercury is always the main ingredient. At Apple Wellness Dental, we use special systems to control mercury use.
Mercury’s Role in Amalgam Stability
Mercury is often questioned, but it’s key because it’s liquid at room temperature. It helps mix the metals together.
Key Binding Properties
Mercury helps amalgam in many ways:
- It makes a soft mix that fits cavity shapes
- It forms strong bonds as it hardens
- It can handle chewing forces up to 200 psi
After setting, less than 5% of mercury is left, says Health Canada. Our Airdrie clinic follows strict rules for disposing of any leftover amalgam.
Key Benefits of Amalgam Fillings
Dental amalgam is a reliable choice for fillings because of its proven success and practical benefits. Even with new materials available, amalgam stands out for certain dental needs. It’s a trusted option for many dentists and patients.
Superior Durability for Posterior Teeth
Amalgam shines in its ability to last long in molars and premolars. Studies show it can last 10–15 years, outlasting composites in tough spots. It’s great for:
- Large cavities needing strong support
- Teeth under heavy chewing forces
- Those seeking long-lasting fixes
At our Airdrie clinic, we’ve seen amalgam fillings hold up better than resin ones, even in strong bites. Its metal composition resists cracking, cutting down on the need for frequent fixes.
Cost-Effective Solution for Large Cavities
Amalgam is a cost-effective pick for big cavities. It’s 30–50% cheaper than composites and covers more area in one visit. Alberta insurance often covers it well, making it affordable for:
- Multi-surface cavities
- Those without dental insurance
- Children’s fillings
Tooth-colored fillings are good for visible areas, but amalgam’s cost and durability win for big back teeth. Its low upkeep means less money spent over time compared to composites needing fixes.
Understanding Risks of Dental Amalgam
Dental amalgam is a common fix for cavities, but safety worries are common. Modern studies have cleared up many myths. They focus on mercury release and rare body reactions.
Mercury Release in Daily Use
Amalgam’s mercury content is a big concern. But, research shows it’s safe. Fillings release very little mercury vapor, less than 7 micrograms a day.
This is well below what Health Canada says is safe. Chewing and grinding can cause a small increase. But, these levels quickly go back to normal.
Allergy Screening Protects Sensitive Patients
Only 1 in 10,000 people have a true mercury allergy, say dental groups. Our Airdrie clinic tests high-risk patients. This includes those with:
- Multiple metal allergies
- Autoimmune conditions
- History of skin reactions
Rare Complications in Practice
Most problems come from how the filling is placed, not the material itself. Over 25 years, we’ve seen a few issues. These include:
- Temporary tooth sensitivity (3-5% of patients)
- Galvanic reactions with gold crowns
- Oral lichenoid lesions near fillings
We catch these rare problems early with regular check-ups. We use digital imaging and occlusion analysis during cleanings.
Safety Guidelines and Regulations
Dental amalgam is safe when used correctly. Health Canada and the American Dental Association (ADA) set rules to protect patients. These rules cover how to handle the material, its use in clinics, and care for special groups.
Health Canada’s Position on Amalgam Use
Health Canada says dental amalgam is safe for most people. But, they suggest extra care for certain cases. Their 2023 update shows mercury levels from fillings are safe, meeting global standards.
They have some rules:
- Avoid new amalgam fillings during pregnancy unless needed
- Use other materials for baby teeth when possible
- Reduce mercury vapor during fillings and removal
ADA Recommendations for Specific Patient Groups
The ADA has special advice for certain groups. They suggest using other options for:
- Children under 6 needing big fillings
- People with neurological issues
- Those who are allergic to mercury
Both Health Canada and the ADA say amalgam is okay for most adults needing strong fillings. Our Airdrie clinic follows these rules by:
- Doing full risk checks on patients
- Using the latest isolation methods
- Talking openly about material choices
Modern Alternatives to Amalgam
Dentistry has changed a lot, giving patients safer and better-looking ways to fix teeth. While amalgam fillings are strong, many people in Canada want options that look like their natural teeth. At our Airdrie practice, we offer two top choices.
Composite Resin Fillings
Composite resin is now the top pick for fixing visible teeth. These fillings match your tooth color, making them almost invisible. Our dentists carefully shape and harden the material to fit perfectly.
Here’s why they’re great:
- No mercury content – fully biocompatible
- Minimal tooth preparation preserves healthy structure
- Instant aesthetic improvement during single visits
Ceramic and Gold Restorations
For those needing extra strength, ceramic crowns and gold inlays are top choices. Our clinic uses advanced technology to make CEREC crowns in one visit. Gold is best for back teeth that need to handle a lot of chewing.
These premium options offer:
- 25+ year lifespan with proper care
- Superior fracture resistance for molars
- Customized fit using digital impressions
Whether you want something that looks good or lasts a long time, we’ve got you covered. Our team helps you switch from old amalgam fillings to new, modern ones. We use the latest techniques and offer same-day services.
Amalgam vs Composite Fillings
Dental patients often wonder: should I choose silver amalgam fillings or tooth-colored composites? This guide compares their performance and looks to help you decide.
Studies show clear differences between these options. Silver amalgam fillings last over 10 years because they:
- Stand up well to chewing pressure
- Work best in moist environments
- Shrink less over time
Composite resin fillings, on the other hand, last about 5-7 years. They’re great for small cavities because they bond well with teeth. This makes them perfect for front teeth and areas you can see.
Aesthetic Considerations in Restorative Work
Modern composites are excellent at matching tooth color. Surveys show 98% of patients are happy with their look. They offer:
- A 16-shade system for perfect matches
- Light-reflective properties like enamel
- No metal visible in smile zones
Our Airdrie clinic has a clear plan:
- Check the cavity size and location
- Look at how you bite
- Talk about what you want to look good
Amalgam is cheaper for big fillings in the back. But composites are the top choice for areas you can see.
Amalgam Removal Process Explained
Modern dentistry puts patient safety and choice first when dealing with old dental work. At Apple Wellness Dental in Airdrie, we follow the latest science for dental amalgam removal. This ensures safety and care for the environment. It also needs special training and tools for the best results.
When Replacement Becomes Necessary
Amalgam fillings usually last 10-15 years. But sometimes, they need to be replaced because of:
- Visible cracks that harm the tooth
- Recurring decay near the filling
- Patients wanting mercury-free options
Our dentists use digital X-rays and lasers to check the fillings. We follow Health Canada’s advice. We only replace fillings when it’s really needed, not just for prevention.
Safety Protocols at Our Airdrie Clinic
Our team is SMART-certified and follows strict mercury safety rules:
- We use rubber dams and oral barriers for isolation
- High-volume suction systems catch 98% of vapors
- Oxygen masks protect patients and staff
- Special filters manage wastewater
These methods, approved by IAOMT, reduce risks during dental amalgam removal. Our clinic has separate air systems in treatment rooms. This keeps the air quality better than Alberta Health standards.
Aftercare for Amalgam Restorations
Proper care is key to making your amalgam fillings last longer and stay safe. Our Airdrie team gives each patient personalized instructions. But here are some tips that usually work for everyone.
Immediate Post-Treatment Guidelines
Here’s what to do for the first 24-48 hours:
- Avoid chewing hard candies, ice, or sticky foods
- Use over-the-counter pain relievers if sensitivity occurs
- Skip extremely hot/cold beverages to prevent expansion stress
- Brush gently around the restoration site
- Schedule bi-annual cleanings at (587) 332-6767
- Use nightguards if you grind teeth
- Limit acidic foods that weaken enamel
- Replace worn fillings during early deterioration stages
With the right care, your fillings can last 10-15 years. If you see cracks, loose fillings, or pain, call us right away.
Addressing the Amalgam Controversy
The debate over dental amalgam is ongoing, driven by misinformation and new research. At Apple Wellness Dental, we focus on truth. We use Health Canada’s rules and the World Health Organization’s advice. Let’s look at what studies say and how it differs from what many believe.
Separating Myths From Scientific Evidence
Many worry about amalgam fillings for three main reasons:
- Myth: “Amalgam mercury causes chronic illnesses” – Health Canada says mercury is safe in fillings
- Myth: “Alternatives are always safer” – Composite resins might need more replacements in molars
- Myth: “Removal prevents health risks” – Taking out fillings can release more mercury than leaving them
Studies show amalgam fillings release less mercury than daily exposure from air and food. Health Canada believes amalgam is safe for most people when done right. This view is backed by over 30 years of research.
Our Approach at Apple Wellness Dental
We have three main rules for talking about fillings:
- Evidence-based guidance: Share ADA and Health Canada info without bias
- Risk assessment: Check for rare mercury allergies or kidney issues
- Personalized solutions: Suggest composite or ceramic options for nervous patients
In Airdrie, we don’t push for fillings to be replaced unless needed. We consider each patient’s health and the state of their teeth. If fillings work well, we might suggest watching them instead of removing them. This approach supports Canada’s efforts to reduce mercury.
Conclusion
Knowing what dental amalgam is helps patients feel more confident when choosing dental treatments. This strong material is great for back teeth because they need to withstand a lot of pressure. Today, dentists use amalgam safely, following Health Canada’s guidelines.
Even though other materials look better, amalgam fillings are long-lasting. At Apple Wellness Dental in Airdrie, we look at each patient’s needs carefully. We consider how big the cavity is, how hard you bite, and your budget.
Studies show that amalgam is safe for most people when used correctly. If you have health concerns or want something that looks better, we can talk about other options. Regular dental visits help keep your fillings working well, no matter what material they’re made of.
Choosing dental treatments should be based on what science says and what you want. If you’re thinking about keeping your amalgam fillings or getting new ones, our team can help. Call us at (587) 332-6767 to talk about your dental health goals with our experienced team.
