Toxic Metals in Dentures

Our teeth are often the first thing people notice when we break out into a smile. When our pearly whites are not as bright as they could be, we seek ways to lighten them up or replace them. Dentures are devices that replace natural teeth that have been lost due to tooth decay, gum disease or tooth injury. Dentures, or false teeth as they are often referred to, are easily removed and reinserted. The need for dentures or dental implants, which have become very popular of late, is the result of progressive periodontal (gum) disease caused by a buildup of dental plaque. Improper brushing or incorrect flossing are often attributed to the cause of dental plaque.

Metal-based Dentures

• In the past, dentures were made of acrylic resin. More popular today are dentures which are metal-based and made of a substantial metal casting. Although the metal base portion of the denture is not in direct contact with underlying supporting tissues, sometimes a soft or hard plastic liner is interposed between the two layers to separate them. A metal-based denture provides the strength needed for a narrow denture to follow the confines of a patient's lower jaw. In addition, the added weight of the metal base provides is preferred by most patients over a lighter one as it provides a more natural sensation.

Toxic Material From Dentures Leak Out Into the Body

• Dentures, as well as dental teeth fillings, contain toxic substances which are released into the mouth and then travel throughout the body causing numerous health problems. Silver fillings contain mercury. Composite dental fillings and old root canals leach various other toxins into the system. And most common denture materials, both the plastic bases and the colorings, are laden with toxic matterand should be replaced with biocompatible dental materials.

Test Your Dentures

• To test dentures for toxins, soak the dentures in cold water for several hours. Repeat the procedure again in fresh water. After soaking the dentures for the third time, any toxin found in the water will not be the result of saliva. Check the denture water for signs of heavy metal residue. If you find any, assume that the dentures are toxic and purchase new ones made of uncolored methaciylate.

Healthy Dentures

• The recent introduction of natural porcelain veneers on dentures helps eliminate the toxic leaks of metal-based dentures. However, these are more costly to produce and not all dentists are familiar with the technique. They continue to use toxic, leaking cements for dentures and crowns.
