At the Institute of Systemic Dentistry, we view cavity repair as more than just plugging a hole in a tooth. For us, it’s about protecting your entire body. That’s why we avoid the use of metal fillings—and especially amalgam, when restoring decayed or damaged teeth.
While traditional dental practices may still use metallic materials, we believe there are safer, healthier, and more effective solutions. In this article, we’ll explain why we avoid metals in cavity repair, what biocompatible alternatives we use, and how this holistic approach benefits our patients in New Jersey and beyond.
The Problem with Metal Fillings
1. Mercury Content in Amalgam
Silver-colored amalgam fillings contain up to 50% mercury, a known neurotoxin. Even in small amounts, mercury vapor can be released during chewing or grinding, and absorbed by the body over time. This exposure can contribute to:
- Neurological symptoms (brain fog, fatigue)
- Immune system suppression
- Hormonal imbalances
- Cardiovascular stress
We believe no toxic substance belongs in your mouth, especially one with systemic implications.
2. Electrical Conductivity and Galvanic Reactions
Metals like mercury, silver, and nickel conduct electricity. When multiple types of metal are present in the mouth (like crowns or braces), they can create a galvanic response—a low-level electrical current that may cause:
- Metallic taste
- Tingling sensations
- Headaches or jaw discomfort
For patients with metal sensitivities, this can contribute to chronic health complaints that are often misdiagnosed.
3. Structural Damage Over Time
Metal fillings expand and contract with temperature changes more than tooth structure. This stress can lead to microfractures, tooth breakage, and further decay—often without symptoms until the damage is advanced.
At our holistic dental office, we focus on preserving the strength and integrity of your natural teeth, and metals often work against that goal.
What Are Biocompatible Fillings?
Biocompatible fillings are materials that work in harmony with the body and do not trigger immune or inflammatory responses. At the Institute of Systemic Dentistry, we carefully select restorative materials that are:
- Free from mercury, nickel, and BPA
- Non-reactive and hypoallergenic
- Stable under temperature and pressure
- Tooth-colored and aesthetically natural
These materials support both oral and whole-body health, and are safe for use in patients with chemical sensitivities, autoimmune disorders, or chronic health conditions.
Types of Biocompatible Filling Materials We Use
1. BPA-Free Composite Resins
- Made from a blend of safe plastic and glass
- Ideal for small to medium cavities
- Bonds directly to the tooth, preserving more natural structure
- Color-matched for a seamless finish
We ensure our composites are BPA-free, avoiding endocrine disruptors that can affect hormonal balance.
2. Glass Ionomer Restorations
- Releases fluoride in low, safe amounts for cavity prevention
- Stronger bonding in moist environments (great for pediatric cases)
- Lower risk of microleakage
Glass ionomers are often used in cases where moisture control is difficult or temporary restorations are needed.
3. Ceramic Inlays and Onlays
- Made from zirconia or porcelain
- Highly durable and long-lasting
- Ideal for larger cavities or cracked teeth
- Completely metal-free and biomimetic
Ceramic restorations are one of our top choices for patients seeking the most natural and inert materials available in modern dentistry.
How We Determine Biocompatibility
No two patients are the same, which is why we go beyond simply avoiding metal, we tailor our treatment to your body’s unique needs. Our evaluations may include:
- Biocompatibility testing (Clifford Materials Reactivity Testing)
- Detailed health history reviews
- Immune system considerations
- Nutritional and detoxification support
This personalized approach reduces the risk of systemic reactions and supports long-term wellness.
Mercury Removal Done Safely
If you already have metal fillings, especially those containing mercury, we can help. We follow strict SMART (Safe Mercury Amalgam Removal Technique) protocols established by the IAOMT (International Academy of Oral Medicine & Toxicology) to ensure:
- Isolation with rubber dams
- High-volume suction and filtration
- Oxygen supplementation for the patient
- Protective barriers for both patient and staff
Our goal is to remove harmful materials safely and completely while minimizing exposure and protecting your body during the process.
Choosing a dentist who uses biocompatible materials isn’t just about avoiding metals, it’s about embracing a whole-body philosophy of health. At the Institute of Systemic Dentistry in Berkeley Heights, NJ, we’re committed to helping our patients achieve lasting oral health using materials that respect the body’s natural systems.
