Mercury-Free Dentistry in Markham, ON

You may have heard some negative press about mercury. It’s in our oceans, our soil and, occasionally, our teeth. Fortunately, our industry has been advancing rapidly and continually in dental treatments. As part of our commitment to comprehensive patient care at 7 Days Dental, we are moving away from this potentially harmful chemical and embracing mercury-free dentistry at our Markham facility.

Cavity fillings are among the most common treatments our Markham dentist uses. This is because negligent or improper oral hygiene can gradually cause tiny holes to form in teeth that require filling. Amalgam fillings are made of a metal alloy that typically includes silver, copper, tin, possibly zinc, and approximately 50 percent mercury.

What's the effect of mercury in dentistry?

Although the FDA does not believe the threat from amalgam fillings is high, mercury is a neurotoxin and can poison and harm wildlife. It can negatively impact organs, such as your brain and kidneys, over time. Amalgam fillings are now considered a moderate risk to patients, as they can slowly release vapour into your mouth, which can accumulate in your body.

However, since dentists have been using these fillings for decades, there are plenty of clinical studies available to consider. Amalgam fillings have been blamed for minimal health problems, and there have been fewer than 150 non-life-threatening reports to the FDA in 20 years. Still, there are growing concerns about them, not to mention that we have better alternatives now anyway.

What are the alternatives to mercury in dentistry?

We offer various options for fillings at our Markham dental office. Since composite resin is cost-effective and closely resembles your natural enamel, we typically recommend this material for fillings. Porcelain is another excellent option for its colour match and durability. In addition to the mercury issue, amalgam fillings are much less inconspicuous.

What are the signs of mercury poisoning?

While consuming too much fish that contains mercury is considered the most common cause, amalgam fillings may be another potential source of mercury poisoning. Individuals should limit their exposure and consumption as much as possible.

Possible symptoms include:

Anxiety, depression, irritability
Memory problems
Numbness or tremors
Pathological shyness

Lack of coordination
Weak muscles
Difficulty hearing and speaking
Difficulty walking
Nerve loss in hands and face
Vision changes

Mercury poisoning can also impact the way a fetus, infant, or young child develops. It might cause delays in cognitive, fine motor, speech and language, and visual-spatial awareness.

If you think you may have mercury poisoning, your doctor will conduct a physical exam, blood test, and urine test. Chelation therapy is used for patients with high mercury levels to help remove and excrete mercury from the body.

Frequently asked questions about mercury-free dentistry in Markham

1. What does ‘mercury-free dentistry’ mean?
It refers to the use of filling materials that do not contain mercury, such as composite resin or porcelain, rather than traditional amalgam (metal alloy) fillings that typically contain mercury.

2. Why do some patients choose mercury-free options?
Some people prefer to avoid mercury due to general concerns—even though the evidence shows minimal risk from amalgam. Mercury-free alternatives offer aesthetic advantages and eliminate any possibility of mercury exposure.

3. Are mercury-free fillings more expensive?
They can cost more than amalgam, primarily because of the materials and bonding process involved. However, many patients find the natural look and reduced concerns about mercury to be worth the additional cost.

4. Are mercury-free fillings covered by dental insurance?
In most cases, insurance will cover the procedure regardless of the filler material, as long as it’s considered standard treatment. It’s best to check with your provider to confirm any differences in coverage.

5. Do mercury-free materials perform as well as amalgam?
Yes. Composite resin and porcelain provide durable, effective restorations. While they may wear differently than metal, they still offer reliable performance for most dental restorations.

6. Are there any health risks with outdated amalgam fillings?
Modern dental research indicates very low health risks from amalgam. Still, since mercury is a neurotoxin, some individuals—and their dental providers—prefer to replace older fillings with mercury-free materials as a precaution.

7. Can all existing amalgam fillings be replaced?
Yes, but it requires careful removal protocols to minimize exposure to mercury vapor. A dentist experienced in safe removal practices is essential for this procedure.
