Understanding Mercury in Saliva: Evaluating Mercury Exposure from Amalgam Fillings
Mercury exposure is a growing concern in the field of health, particularly when it comes to its presence in dental amalgam fillings. Amalgam fillings, widely used in dental procedures for decades, contain a mixture of metals, including mercury. Over time, these fillings can release small amounts of mercury into the body, raising concerns about long-term health effects. One of the most effective ways to measure this exposure is through a mercury in saliva test. This test allows for an accurate evaluation of how much mercury a person may be absorbing through their dental fillings, which can have implications for their overall health.
How Are People Exposed to Mercury?
Mercury exposure occurs in several ways, and it’s essential to recognize the primary sources of mercury that may affect our health. Some of the most common sources of mercury include:
- Contaminated Food and Water: Certain fish, especially large predatory fish, contain high levels of mercury. Additionally, polluted water sources can contribute to mercury exposure.
- Inhalation of Mercury Vapors: Breathing in mercury vapor can occur in areas where mercury is present, such as in certain industrial settings.
- Dental Amalgam Fillings: Dental amalgam fillings, which contain a mixture of metals including mercury, are another significant source of mercury exposure. Over time, these fillings release small amounts of mercury into the body, and this exposure can become chronic, potentially leading to health problems over an extended period.
The Role of Amalgam Fillings in Mercury Exposure
Amalgam fillings can release mercury into the body over time, especially through mechanical pressure. Chewing and brushing teeth can cause the fillings to release more mercury. Factors like the number of fillings, their age, and the materials used can all influence how much mercury is released. Additionally, consuming acidic or hot drinks can exacerbate this release.
The mercury in saliva test is a reliable way to measure how much mercury a person is being exposed to from their amalgam fillings. By collecting saliva samples and testing for mercury content, this test can help provide a clearer picture of one’s exposure levels.
Preparing for the Mercury in Saliva Test
To ensure accurate results, it’s important to prepare properly for the mercury in saliva test. Here are the key guidelines to follow before testing:
- Avoid Eating or Drinking for 2 Hours Before the Test: To prevent contamination from mercury in food or drinks, refrain from eating or drinking for at least two hours before collecting your saliva sample.
- No Teeth Polishing: Do not brush your teeth or use any teeth polish prior to the test, as this can release additional mercury from the fillings.
- Wait 2 Months After a Dental Visit: If you’ve recently visited the dentist, it’s best to wait at least two months before taking the test. The mercury level could be temporarily elevated due to dental treatments.
Two Sample Collection for Accurate Results
Because mercury is released more during chewing than at rest, the mercury in saliva test requires two samples: one during ‘rest’ (when not chewing) and one during chewing. On average, people chew for about one hour per day, leaving 23 hours of rest time. By comparing the results from these two samples, a more accurate picture of daily mercury exposure can be determined.
When Should You Consider the Mercury in Saliva Test?
Certain health complaints may be linked to excessive mercury exposure, particularly from amalgam fillings. If you experience any of the following conditions, it may be worth considering the mercury in saliva test:
- Anemia (Low Red Blood Cell Count)
- Anorexia or Loss of Appetite
- High Blood Pressure
- Depression or Anxiety
- Memory Problems or Cognitive Decline
- Irritability or Mood Swings
- Headaches or Migraines
- Skin Problems, Rashes, or Eczema
- Gastrointestinal Issues (e.g., Diarrhea or Stomach Pain)
- Insomnia or Sleep Disturbances
- Inflamed Gums
- Chronic Fatigue
- Fertility Issues
- Weakened Immune System
If you’re experiencing any of these symptoms, it might be time to explore whether mercury exposure from amalgam fillings could be a contributing factor.
Complementary Tests to Assess Mercury Exposure
To get a more comprehensive view of mercury toxicity and your body’s ability to detoxify mercury, there are several complementary tests that can be useful:
- Trace Elements in Blood: Some individuals are more sensitive to mercury than others. Measuring the levels of trace elements, such as selenium, which is involved in the detoxification of mercury, can provide insight into your body’s ability to process and eliminate mercury.
- DMPS Test (Urine): The DMPS test is a urine test that helps assess the overall mercury load in your body. This test measures how much mercury your body is holding, as DMPS binds to heavy metals and helps eliminate them through urine.
- MELISA Test: The MELISA test is an immunological test that checks for sensitivity to metals, including mercury. This test is particularly useful for identifying if a person has an immune reaction to metals in dental fillings or other medical applications.
Conclusion
Mercury exposure from amalgam fillings is a serious concern, especially when it accumulates over time. The mercury in saliva test is an invaluable tool in assessing how much mercury you may be absorbing through your dental fillings. If you are experiencing any of the symptoms associated with mercury toxicity, or if you simply want to learn more about your exposure levels, this test can provide critical insights into your health.
By preparing properly for the test and understanding the implications of your results, you can take proactive steps to reduce your exposure and safeguard your well-being. Always consult with a healthcare professional if you suspect mercury toxicity or if you have concerns about your amalgam fillings and their potential impact on your health.
