Could Your Fillings Be Affecting Your Thyroid Health?

January 15, 2020

There is a saying in functional medicine—if you are standing on a tack, you don’t take a pill to alleviate the pain.  You remove the tack.  In the case of autoimmune conditions like Hashimoto’s hypothyroidism, there can be multiple tacks, and one of these may be something you had not considered–your mercury amalgam dental fillings.

Those silver fillings you may still have are 50% mercury by weight, according to the FDA.  The rest is composed of silver, tin, and copper.  These are still used today because they are inexpensive and long-lasting.  The drawback is that they continually release small amounts of mercury vapor, which can be inhaled and absorbed by the lungs.  Exposure to heat and pressure from chewing increases the release of mercury. 

According to Dr. Izabella Wentz, author of the book Root Cause, research has shown that mercury is absorbed by the thyroid.  More amalgam fillings means more mercury deposited in thyroid tissue, and symptoms of this can include digestive issues, joint pain, fatigue, brain fog/trouble concentrating, and hair loss.  One 2007-2008 study showed a definite correlation between women with mercury exposure and anti-Tg antibodies.

If you have Hashimoto’s and dental amalgams, we encourage you to consider the MELISA (Memory Lymphocyte Immunostimulation Assay) test, which is a simple blood test used to diagnose metal allergies.  The results of this test can help you decide whether to undergo removal of mercury amalgam fillings.  Another study showed that patients with Hashimoto’s and amalgams showed a remarkable decrease in their anti-TPO and anti-Tg antibodies when the fillings were removed.

It is vital that fillings containing mercury are removed safely.  The International Academy of Oral Medicine and Toxicology (IAOMT) has developed the Safe Mercury Amalgam Removal Technique (SMART) for this procedure.  This protocol reduces the risk of exposure to mercury vapor to dental professionals as well as their patients.  There are many steps that should be taken, including ensuring adequate ventilation, using copious amounts of water to reduce heat from dental tools, and the use of face/head coverings by everyone in the room.  Many dental professionals will remove mercury fillings-but not all follow this procedure.  It’s important to do your research!

At Well Life, we also encourage everyone to follow the Institute of Functional Medicine’s dental amalgam removal protocol, which includes pre- and post-procedure testing and supplementation to ensure a healthy outcome.
