What Are Symptoms of Mercury Poison?


The toxicity of mercury has been researched and well-known for decades. Many of us are aware of the dangers that overexposure to mercury can cause, but rarely do we consider our dental work to be a part of the problem.

At BioSafeDentistry, we advocate mercury-free dentistry and alternatives to amalgam fillings (the “silver” fillings that are the most popular choice for filling cavities) because of the health risks that are involved. Research indicates that the mercury content in amalgam fillings can continuously give off mercury vapor, which our bodies absorb over time. Exposure to mercury can affect your physical and mental health, and recovery can be difficult. Because symptoms of mercury poisoning can vary, it is especially important to understand how our bodies are affected.

What are Physical Symptoms of Mercury Poisoning?

The physical symptoms of mercury poison can take many different forms. Symptoms can also vary depending on the amount and length of time you are exposed to mercury. Symptoms of mercury poisoning can include:

  • Fatigue
  • Heart disease
  • Digestive problems
  • Cancer
  • Allergies
  • Fibromyalgia
  • Headaches
  • Muscle weakness
  • Twitching
  • Respiratory problems
  • Kidney disease

This is not an exhaustive list, and just because you experience these symptoms (for instance, if you get frequent headaches) does not mean you have been poisoned. However, if you have amalgam fillings or have been exposed to mercury by other means, be conscious of what your body is telling you. You could possibly have an allergy or increased sensitivity to mercury.

Mental and Emotional Symptoms of Mercury Poision.

As a neurotoxin, mercury is especially known for the adverse effects it can have on our psychological health. This can cause a variety of emotional issues and mental illnesses, including acute symptoms such as difficulty concentrating or dizziness. The following psychological symptoms can be signs of mercury poisoning:

  • Irritability
  • Anxiety
  • Depression
  • Insomnia
  • Mood swings
  • Hallucinations
  • Dizziness
  • Difficulty concentrating

Remember that your mental well-being is just as important as your physical health. If you are concerned that mercury could be affecting your mental health, contact your doctor.

Dental Health

While many dentists have always used mercury and amalgam fillings, and are convinced it is safe to use, it can actually cause even more issues with your dental health. Signs of mercury toxicity in the mouth can include:

  • Bleeding gums
  • Gingivitis/periodontal disease
  • Mouth ulcers
  • Dark spots on tongue
  • Tooth loss
  • Root canals

Its important to protect yourself when having mercury fillings removed. There are certain mercury fillings removal supplements that you’ll need to take to protect you from mercury poising.

For many patients, mercury exposure could be the main trigger of the above oral symptoms. Fortunately, there are plenty of safe alternatives to amalgam fillings, such as ceramic or composite resin fillings. Be sure to discuss mercury-free options with your dentist, or use our website to search for a mercury-free dentist. If you are a mercury-free dentist, you can list your practice.
