Mercury Poisoning from Fillings


For decades, the use of mercury in dental care has been an accepted practice by dentists and patients alike. This is based on the belief that low levels of mercury are not harmful to our health; however, recent scientific research has caused some controversy. Many patients aren’t fully aware of what goes into their dental care, and so they are exposed to various toxic materials, including mercury.

Amalgam fillings, which are composed of various metals, are by far the most popular choice when it comes to filling cavities. However, it is possible that these “silver” fillings (so-called because of their shiny color) can continuously release mercury vapor into our bodies, harming our teeth and overall health.

If you have multiple amalgam fillings, it is important to understand the possible effects they can have on your health. Allergies and sensitivity to mercury can increase the severity of symptoms. Symptoms can also vary between patients.

Oral Health

While amalgam fillings should fix cavities and the chances of infection, high amounts of mercury can actually exacerbate an existing issue. Oral symptoms of mercury poisoning can include:

  • Gingivitis
  • Gum pain/bleeding
  • Tooth loss
  • Root canals
  • Abscesses

If you are experiencing any oral discomfort such as the symptoms listed above, the mercury in amalgam fillings could be the culprit. Discuss any concerns you have with your dentist, and be sure to discuss safe removal of amalgam fillings and mercury-free alternatives in the future.

Mental Health

As a neurotoxin, mercury can have serious effects on your nervous system. Extended exposure to mercury can affect your entire mental well-being. As you keep an eye out for signs of mercury poisoning, be especially wary of emotional and psychological symptoms, such as:

  • Depression
  • Panic attacks
  • Anxiety
  • Mood swings
  • Memory loss
  • Dizziness
  • Hallucinations
  • Suicidal thoughts

Mercury is also believed to be the possible trigger for serious conditions such as Alzheimer’s and ALS. Share any concerns you may have with your physician to receive proper treatment.

Other Symptoms

While dental and mental health are the main concerns of those with amalgam fillings, it is important to remember that mercury can have effects on your entire body. Symptoms that can affect the entire body and its organ systems include:

  • Irregularities in menstrual cycles
  • Hot flashes
  • Exacerbated symptoms of PMS
  • Respiratory problems, including asthma, COPD and emphysema
  • Glaucoma
  • Cataracts
  • Heart failure
  • Cancer

Before having any of your amalgam fillings removed, you’ll want to take mercury filling removal supplements prior to any procedure.

Because there are dozens of mercury poisoning symptoms that can affect us all differently, it is more important than ever to find a mercury-free dentist. At BioSafeDentistry, we are dedicated to informing patients and creating safer practices for all dentists.
