Old silver fillings contain about 50% mercury by weight, so wondering whether removal could expose you to more harm than leaving them alone is a fair concern. Mercury filling removal in Wilmington, NC can be done safely, but only when a dentist follows specific precautions designed to minimize your exposure during the process. That protocol is called SMART, and it changes nearly everything about how removal is handled.
Why Mercury Filling Removal in Wilmington, NC Requires a Special Protocol
Amalgam fillings, the silver-colored restorations that were standard practice for decades, release small amounts of mercury vapor during chewing, grinding, and temperature changes. The World Health Organization recognizes amalgam as the single largest source of mercury exposure for people who have these fillings. That background release is one thing. Drilling out a filling without precautions is another, because the drilling process generates heat and fragments that can spike vapor and particle levels dramatically.
This is the core reason SMART removal exists. SMART stands for Safe Mercury Amalgam Removal Technique, a protocol developed and taught by the International Academy of Oral Medicine and Toxicology (IAOMT). It was built specifically to protect patients, dental staff, and the environment from the concentrated burst of mercury that standard removal can create.
According to the IAOMT, amalgam removal without protective measures can increase a patient’s mercury exposure by a factor of several times compared to leaving the filling undisturbed. That’s the baseline risk SMART is designed to bring back down to the lowest level reasonably achievable.
Without these precautions, a patient could absorb a higher dose of mercury during a single 20-minute removal appointment than they would have absorbed from the filling over years of normal use. That risk is avoidable.
What Makes SMART Different From Standard Amalgam Removal
SMART is a layered system of overlapping protections. No single step does all the work. The combination is what makes the difference.
Here’s what a properly performed SMART removal typically includes:
- Rubber dam placement. A thin barrier of latex or non-latex material seals off the tooth from the rest of your mouth, so fragments and particles can’t reach your throat or get swallowed.
- Chunking technique. Instead of grinding the filling into fine dust, the dentist cuts the amalgam into large sections and removes them in chunks. Bigger pieces mean less vapor released into the air.
- High-volume evacuation. A powerful suction device is positioned right at the tooth throughout the procedure to capture mercury particles before they travel into the air.
- Nasal oxygen or an air filtration mask. You breathe clean air through your nose rather than drawing in any aerosol from the procedure.
- Full-body draping and head/neck barriers. These protect your skin and clothing from microscopic particles that can settle during removal.
- Medical-grade air filtration in the operatory. The room itself is filtered to protect staff as well as you.
- Pre- and post-appointment dietary or supplement support. Many biological dentists recommend supporting your body’s natural detoxification pathways before and after removal. Your dentist will guide you on what fits your health history.

Should You Remove Your Old Amalgam Fillings?
This question doesn’t have a single answer. The decision depends on factors specific to you.
If your fillings are intact and you have no symptoms, some patients choose to leave them in place and simply avoid adding any new amalgam. Mercury release from an undisturbed filling is relatively low compared to the exposure during removal, so this is a reasonable approach.
If your fillings are cracked, corroded, or failing, removal is often necessary regardless of the mercury question. A broken filling needs to come out. At that point, doing the removal the right way, using SMART, is simply the standard of care for a biological dental practice.
If you have biocompatibility concerns, meaning your body may be more reactive to metals, or if a healthcare provider has advised you to reduce your mercury load, a conversation with a biological dentist is the right starting point. The Agency for Toxic Substances and Disease Registry (ATSDR) notes that some individuals, including pregnant women, children, and people with kidney disease, may be more sensitive to mercury exposure, which is a factor worth discussing with both your physician and your dentist.
A biological dentist looks at your overall health picture, not just the tooth. What Is a Biological Dentist? explains this approach in plain language if you’re newer to this way of thinking about dental care.
What Replaces an Amalgam Filling After Removal
Once a filling is removed, the tooth needs a new restoration. In a biological dental practice, that replacement is always a biocompatible, metal-free material. The most common options are:
- Composite resin: A tooth-colored material bonded directly to the tooth. Modern composites are durable, mercury-free, and blend visually with your natural tooth structure.
- Ceramic inlays or onlays: Porcelain restorations made to fit the specific shape of the cavity. These are often used for larger areas where composite would be under too much stress.
- Zirconia restorations: An exceptionally hard ceramic option used for larger back-tooth restorations.
The choice depends on the size of the original filling and where the tooth sits in your mouth. Your dentist will walk you through the best option before any removal begins.

How to Find a SMART-Certified Dentist in Wilmington
Not every dentist who mentions holistic or biological dentistry has completed formal SMART training. The IAOMT certifies dentists at different levels based on their coursework and demonstrated competency. When you’re evaluating a practice, it’s worth asking directly:
- Is the dentist IAOMT-accredited or SMART-certified?
- Does the practice use a rubber dam and chunking technique as standard for amalgam removal?
- Is a high-volume evacuation system used throughout the procedure?
- What air filtration system does the operatory use?
A practice that answers these questions clearly and without hesitation is one that has thought carefully about patient safety in this area.
What to Expect at Your Appointment
A SMART removal appointment feels more involved than a standard filling visit, because it is. Setup takes longer. You’ll be draped and fitted with a nasal cannula or mask before the dentist begins. Rubber dam placement adds a few minutes.
The removal itself is often faster than patients expect. Chunking is a quicker technique than grinding. Most single-tooth removals, once all protective measures are in place, take 15 to 30 minutes.
The full appointment, including setup and placing the replacement restoration, typically runs 45 to 75 minutes. Some patients feel a little tired afterward. Staying well hydrated, eating a nutrient-rich meal before your appointment, and following any supplement guidance your dentist provides will support your body through the process.
The National Institutes of Health has funded ongoing research into mercury bioaccumulation and individual variation in how people process heavy metals, which is one reason biological dentists pay close attention to your full health history before scheduling removal.
Frequently Asked Questions
Is it safe to remove old mercury fillings if I don’t have any symptoms?
Removing old amalgam fillings can be safe when done using the SMART protocol, even if you currently have no symptoms. The removal itself carries the highest exposure risk, so protective measures are essential regardless of your starting point. Many patients choose to have failing or cracked fillings removed right away while waiting on intact fillings until they naturally need replacement.
Is mercury filling removal in Wilmington, NC covered by dental insurance?
Insurance coverage for amalgam removal varies widely by plan and depends on whether there’s a documented clinical reason, such as a cracked or failing filling. Elective removal for biocompatibility reasons is often not covered. The best approach is to ask the dental office to verify your benefits before scheduling, so you know what to expect financially.
How long does SMART mercury removal take?
A single-tooth SMART removal appointment typically takes 45 to 75 minutes from start to finish, including setup, protective measures, the removal itself, and placing the replacement restoration. If you have multiple fillings, your dentist may spread the work across several appointments to reduce the total exposure load per session.
Can I have all my mercury fillings removed at once?
Most biological dentists recommend removing amalgam fillings in stages rather than all at once. Spacing out appointments gives your body time to process and clear any residual exposure between sessions. Your dentist will help you prioritize which fillings to address first, usually starting with ones that are already failing or showing signs of breakdown.
What’s the difference between a biological dentist and a holistic dentist?
The terms are often used interchangeably, but “biological dentist” tends to emphasize clinical protocols like SMART removal, biocompatibility testing, and materials that work with the body’s chemistry. “Holistic dentist” often signals a broader philosophy that includes whole-body health, nutrition, and the connection between oral and systemic health. A dentist who identifies as both applies that philosophy through evidence-based clinical protocols.
Will I feel different after my mercury fillings are removed?
Patients report a wide range of experiences after SMART removal, from no noticeable change to gradual improvements in how they feel overall. Removing amalgam fillings is not a treatment for any specific health condition, and no responsible practitioner would promise a particular health outcome. What removal does is reduce an ongoing source of heavy metal exposure for people concerned about biocompatibility or sensitivity to metals.
Ready to talk through whether mercury filling removal is right for you?
The decision to remove old amalgam fillings is personal, and it deserves a real conversation with a dentist who understands both the risks of removal and the protocols that make it as safe as possible.
