When most of us think about dental health, we focus on brushing, flossing, and keeping cavities at bay. But have you ever stopped to consider what’s inside your mouth - not just your teeth and gums, but the materials your dentist has placed there?
It turns out that the metals commonly used in fillings, crowns, braces, and implants may be doing more harm than good.
Dental Amalgam and Mercury Exposure
Dental amalgam, often called “silver fillings,” has been used for well over a century. But here’s what many people don’t realize: these fillings are made of about 50% mercury. Mercury is the second most toxic naturally occurring element on Earth (after plutonium), and it has no place in the human body.
Over time, mercury from fillings can vaporize and be inhaled or absorbed. This chronic, low-level exposure has been associated with a wide range of symptoms, including:
-
Cyclical vomiting
-
Blood in the stools
-
Mood disorders and anxiety
-
Flu-like symptoms
-
Behavioural issues, especially in children
Long-term exposure has also been linked to serious neurological conditions such as Alzheimer’s, Parkinson’s disease, and multiple sclerosis.
It’s Not Just Fillings
While mercury in fillings gets most of the attention, other common dental materials also raise concerns. Metals such as nickel, chromium, and cobalt are frequently used in braces, crowns, and partial dentures. Each of these metals can release ions or particles into the body over time.
Every time you chew food, drink something hot, or even swallow, microscopic amounts of these metals can vaporize or leach into your system. The body recognizes these as toxins, and over time this can contribute to systemic inflammation, immune dysregulation, or unexplained health problems.
Safer Alternatives Exist
The good news is you don’t have to settle for toxic metals in your mouth. Dentistry has come a long way, and there are now safe, biocompatible options available.
-
Composite or milled ceramic fillings - These modern materials look natural, are durable, and don’t release harmful substances.
-
Ceramic crowns and bridges - Strong and aesthetic, they eliminate the need for metal.
-
Zirconia implants - A biocompatible, metal-free alternative to titanium implants.
-
Acetyl partial dentures - A thermoplastic option that doesn’t absorb or release chemicals and is resistant to bacteria.
By choosing these alternatives, you reduce your toxic burden while protecting both your dental health and overall wellbeing.
How to Protect Yourself
If you already have metal dental work, don’t panic - but don’t ignore it either. Here are some steps you can take:
-
Consult a holistic or biological dentist. These practitioners are specifically trained in the safe removal and replacement of metal dental materials. They use special protocols to minimize mercury exposure during removal.
-
Ask questions. Don’t blindly accept what’s being placed in your mouth. Request a full explanation of the materials being used and why.
-
Listen to your body. If you’ve had metal placed in your mouth and developed health issues soon after, it’s worth exploring whether the two may be connected.
The Bigger Picture
Your mouth is not separate from your body; it’s the gateway to your entire system. What goes in your mouth doesn’t just affect your teeth; it influences your brain, immune system, and overall health.
Modern dentistry offers us the opportunity to move away from outdated, toxic materials and embrace biocompatible, health-supporting alternatives. But that shift often requires being proactive, asking questions, and sometimes seeking out a new kind of dental professional.
The bottom line: If you value your health, pay close attention to what’s in your mouth. Metals may be convenient and cheap for the dental industry, but your body pays the price. Choosing safe, holistic alternatives is one of the most powerful steps you can take toward lifelong wellness.
