Mercury-Free Dentistry

Dr. Medlock has been concerned about the Mercury Amalgam issue for twenty four years. The word "silver" amalgam is a misnomer. Amalgam is 50% mercury and should be called "mercury amalgam". Mercury vapor outgases from the mercury amalgam for the entire life of the restoration. Mercury vapor is the most toxic form of mercury and mercury is the most toxic, radioactive metal known to man. There has never been shown to be a safe level of mercury vapor, No observable effect level (NOEL). For those reasons, the American Dental Association arguments that amalgam is safe is simply ludicrous. For these reasons, Dr. Medlock has refused to use amalgam for the last twenty four years and states, "Amalgam should be banned from dentistry." The use of mercury has been banned from all other aspects of medicine.

Because amalgam is extremely hazardous during the removal process, Dr. Medlock follows the I.A.O.M.T. guidelines for safe removal. Dr. Medlock feels that utilizing 4 filter systems in each opertory creates one of the most well equipped offices for dealing with Hg amalgam removal.

Metal-free Dentistry Replacement Alternatives


Composite White Fillings

These are very good for small to medium sized fillings. They are bonded into place, removing the necessity to provide 'keys' in the tooth, thus conserving the tooth tissue.



Inlays (composite or porcelain)

Composite inlays are made of a very hard 'plastic' and are generally a better fit and less abrasive.

Ceramic inlays are advantageous to patients who may be allergic to petrochemicals - they are extremely hard however, and can cause abrasion to the opposing teeth.



Crowns and Bridges

Reinforced all-porcelain crowns & bridges have been available for over 9 years. Today metal free restorations are extremely biocompatible and very durable and cosmetic.
