A Dentist's Story: Brain Fog, Memory Loss, and Mercury Exposure
October 16, 2026 | Dr. Jigar Gandhi: Tooth and Body
In the video above, Dr. Jigar Gandhi shares a story that is more personal than most: his own. In early 2024, he began noticing twitches in his neck and moments where his thinking seemed to stall. His team had noticed something even earlier. Since around October or November 2023, he had been forgetting things during the workday.
For a dentist who had spent years drilling out silver amalgam fillings, the pattern eventually pointed in one direction: possible mercury exposure. This article walks through Dr. Gandhi's experience, what dental amalgam is, why removing it can release mercury vapor, which symptoms have been associated with exposure, and how safe removal protocols are designed to protect both patients and the dental team.
Dr. Gandhi's Story: When the Symptoms Started
Neck Twitches and Neurological "Blocks"
The first signs were physical and hard to explain. Dr. Gandhi noticed recurring twitches in his neck, along with what he describes as neurological blocks, brief moments where his mind simply would not connect the dots. On their own, symptoms like these are easy to dismiss as stress, poor sleep, or a busy schedule.
Memory Lapses His Team Noticed First
When he asked his staff what was going on, they told him he had been forgetting things for months. The team started leaving sticky notes to keep the day on track, with reminders such as which patient still needed to be numbed or which visit was a follow up. Dr. Gandhi recalls sitting down in his office believing he had already numbed a patient when he had not. He also describes severe brain fog during this period.
Moments like these matter. In dentistry, focus and precision are part of patient safety, so memory lapses were not something he could ignore.
The Moment Everything Aligned
Things came into focus around a conversation involving Gary Brecka, host of The Ultimate Human podcast, whom Dr. Gandhi had treated for cavitations (areas of poorly healed or infected tissue in the jawbone). Hearing mercury toxicity discussed in that context hit home. As Dr. Gandhi explains, he had spent years removing mercury fillings from patients without realizing how much exposure he himself might be taking on.
When he walked through his symptoms with a mentor who had personally been through mercury toxicity, the response was immediate recognition: every one of those symptoms sounded familiar. Dr. Gandhi asked for guidance and began working on his own recovery. Today, that experience shapes how seriously he takes safety during every amalgam removal.
What Is Dental Amalgam?
Dental amalgam, often called a silver filling, has been used for well over a century. It is a mixture of metals, and roughly half of it by weight is elemental mercury, combined with silver, tin, and copper. Amalgam is durable and inexpensive, which is why it became so common.
Amalgam fillings release small amounts of mercury vapor over time, and that release increases when the filling is heated, ground, or drilled. That is why the removal process, not just the filling itself, is a key focus in biological dentistry.
What Regulators Say
In 2020, the U.S. Food and Drug Administration recommended that certain higher risk groups avoid new amalgam fillings when appropriate alternatives exist. These groups include pregnant and nursing women, young children, people with certain neurological conditions or impaired kidney function, and people with a known sensitivity to mercury. The FDA also advises against removing amalgam fillings that are in good condition unless there is a medical reason to do so, because removal itself can increase short term exposure. That makes how a filling is removed especially important.
Why Dentists and Dental Teams Face Mercury Exposure
Patients are not the only ones in the room during a filling removal. When an amalgam filling is drilled, mercury vapor and fine particles can be released near the dentist, assistant, and hygienist. Over a career of thousands of procedures, that adds up. Occupational exposure among dental professionals has been studied for decades, and research suggests that exposure levels depend heavily on the precautions used in the office.
Dr. Gandhi's story illustrates a point that is easy to overlook: a dentist can be exposed day after day without realizing it, especially when the effects build slowly.
Symptoms Associated With Mercury Vapor Exposure
Health agencies have described a range of symptoms associated with longer term exposure to elemental mercury vapor. These may include:
- Tremors, twitching, or muscle changes
- Memory problems and difficulty concentrating
- Brain fog and slowed thinking
- Mood changes, irritability, or anxiety
- Trouble sleeping
- Headaches and fatigue
Why These Symptoms Are Easy to Miss
Many of these symptoms overlap with stress, burnout, thyroid problems, nutrient deficiencies, and other conditions. They can also come on gradually, which is why the people around you may notice changes before you do, just as Dr. Gandhi's team did. Experiencing these symptoms does not mean you have mercury toxicity. It does mean they are worth discussing with your physician, who can order appropriate testing and rule out other causes.
How Safe Amalgam Removal Reduces Exposure
At Tooth & Body, amalgam fillings are removed using the SMART protocol (Safe Mercury Amalgam Removal Technique), a set of safety steps developed to reduce mercury exposure for both patients and the dental team.
Key Steps in the SMART Protocol
- Isolation: A dental dam helps keep particles away from the throat and surrounding tissue.
- High volume suction: Suction placed near the tooth captures vapor and debris as it is released.
- Sectioning the filling: The filling is cut into chunks and lifted out rather than ground down, which limits vapor.
- Cooling water: Water spray reduces heat, which reduces vapor release.
- Air filtration: Room air filtration helps capture mercury vapor in the treatment area.
- Protective barriers: The patient's skin, face, and airway are covered or supplied with clean air, and the team wears protective equipment.
Protecting the Team, Too
These steps protect everyone in the operatory, not just the patient. Having experienced possible exposure firsthand, Dr. Gandhi views these precautions as non negotiable. Once fillings are removed, many patients choose metal free restorations. You can learn more about that choice in our article on why patients switch from titanium to ceramic implants.
Mercury and the Bigger Picture of Whole Body Health
Biological dentistry looks at the mouth as part of the whole body. Mercury fillings are one factor Dr. Gandhi evaluates, alongside hidden infections in the jawbone, root canal treated teeth, and gum health. Research into the connection between oral health and systemic health is ongoing, and Dr. Gandhi approaches each case with imaging, a full health history, and a clear explanation of the options.
Frequently Asked Questions
What are the symptoms of mercury exposure from fillings?
Symptoms associated with mercury vapor exposure may include tremors or twitching, memory problems, brain fog, mood changes, trouble sleeping, headaches, and fatigue. These symptoms overlap with many other conditions, so a physician should evaluate them.
Can dentists be exposed to mercury from removing fillings?
Yes. Drilling amalgam fillings can release mercury vapor and particles near the dental team. Exposure levels depend on the safety measures used, which is why protocols like SMART include suction, filtration, and protective equipment for the team.
Should I have my amalgam fillings removed?
Not necessarily. The FDA advises against removing fillings in good condition unless there is a medical reason. A biological dentist can review the condition of your fillings, your health history, and your concerns to help you decide whether removal makes sense for you.
What is the SMART protocol?
SMART stands for Safe Mercury Amalgam Removal Technique. It is a set of precautions designed to reduce mercury exposure during removal: isolation, high volume suction, sectioning the filling, cooling water, air filtration, and protective barriers.
How is mercury exposure tested?
Physicians commonly use blood and urine tests to assess mercury exposure. Blood levels tend to reflect recent exposure, while urine levels can reflect longer term exposure to elemental mercury. Your physician can recommend the right test and interpret the results.
