Amalgam and Other Alloys in the Mouth

Silver or amalgam fillings contain 50 percent mercury, which has been scientifically proven to be more toxic than lead, cadmium, or arsenic. Amalgam fillings can potentially have neurotoxic effects. Some healthcare experts believe that mercury causes physical and psychological problems and directly affects most brain functions.

Mercury can enter the body in several ways. Small particles of amalgam from the filling, which dissolve in saliva, can be swallowed and then absorbed into the bloodstream and nerves through the intestines. A certain percentage of mercury vaporizes from the fillings and is absorbed into the lungs through inhalation. Mercury can also directly penetrate the tooth and, through the dental nerve, travel along other nerves to the brain, where it is stored. There is also a possibility that mercury starts to leak from the amalgam filling and gradually penetrates organs in small quantities. The body deposits them in tissues and organs, causing various physical and psychological problems and illnesses.

Given all of the above, there are at least 5 good reasons to replace amalgam fillings with composite white fillings or porcelain or composite inlays:

1. HYGIENE: Amalgam fillings contract more than the tooth in cold temperatures. Over time, gaps form between the filling and the tooth, where bacteria settle and cannot be removed even with meticulous oral hygiene.

2. TOOTH DAMAGE: Amalgam fillings expand more than the tooth when consuming hot food and drinks. This creates tension in the tooth and can lead to cracks, which may result in tooth loss.

3. MERCURY: Amalgam contains toxic mercury, which is proven to be harmful to our bodies. More and more experts believe that mercury causes physical and psychological issues and directly affects most brain functions.

4. GALVANIC REACTIONS: The presence of amalgam fillings and/or other metals in the mouth leads to the generation of low-voltage electrical currents, causing the well-known “metallic sensation” in the mouth.

5. AESTHETICS: An increasing number of people find amalgam fillings unattractive due to their gray appearance. They desire a wide, relaxed, and white smile.
