Is Mercury Released from Amalgam Fillings During Teeth Clenching:

Mercury release amalgam fillings during teeth clenching

Amalgam filling removal in people who grind their teeth can be challenging cases. Clenching accelerates mercury release from amalgam fillings as a result of friction and heat. Friction from teeth contact causes release of mercury gas that can be absorbed into the body. Mercury containing fillings break-down faster and pieces can break away and be ingested. Wear of teeth enamel including cracking, chipping and abrading will decay and will prematurely break down existing fillings. In the picture below, the yellow area adjacent to the amalgam filling is where all of the white enamel has been worn away, exposing the underlying Dentin. The amalgam filling is also crumbling and separating from the tooth.

TMJ Problems with Amalgam Fillings


TMJ or TMD is defined as a misalignment between the best fit of the teeth and the path of closure of the jaw. Airway problems also cause teeth clenching during sleep. It is also typically complicated by an upper airway problem and general complaints from the patient about head, neck and upper back tension. The “TMJ” causes tooth clenching and grinding or bruxism among many other symptoms.  Temporomandibular joint problems can be diagnosed and cured by a specially trained dentist using dental appliances for sleep apnea and TMJ.

Amalgam fillings Release More Mercury and Break Down Faster When There is Teeth Clenching

In the case below, the amalgam filling was removed using the safe amalgam filling material protocol.  Additionally the TMJ problem was improved with a bite adjustment and the exposed dentin was sealed (as was the original amalgam filling material) with a BPA-free tooth colored composite filling material. Tooth colored composites can out perform silver fillings in many ways, but not having mercury sure makes them a less concerning chioce.
