Materials and Toxicity
(Refer to “Recommended General Safety Measures” on this site to limit exposure during procedures, posted 2/16/13.)
• Composites and Other Materials
The least toxic dental materials are ceramic and gold. Composite fillings are made of tiny glass particles suspended in a resin (plastic) matrix. Most composite fillings are made of the petro-chemical bis-phenol which some research indicates leaches estrogen-like substances and disrupts hormones. Most ceramic and resin-based materials contain metals in the form of oxides (such as aluminum) or even heavy metals (such as cobalt, barium or cadmium). Dentures contain cadmium to make the gums have a nice pink color and for color stabilization.
Ceramic and porcelain materials as used for teeth are basically the same; with newest porcelain products being the most durable. Dental products may be of questionable safety but are chosen for their durability and aesthetic value with often little thought for their associated health risks in your mouth 24/7. Of special concern are dental adhesives or cements used for gluing crowns in place.
Porcelain crowns can wear down natural teeth as they may actually be harder and composite fillings may erode over time. You may also want to consider the option of replacing porcelain or ceramic fused over metal crowns (gold is the safest metal but others are mixtures of metals) with all porcelain crowns.
For extensive dental restoration including total removal of amalgam fillings with composite replacements, full mouth restoration with porcelain crowns, etc – the best advice is to seek out a dentist that is a qualified neuromuscular/orthodontic and cosmetic dentist to ensure the best look and function.
Bonding and cement agents used for crowns and composite filling material are of concern but choices may be limited. Check with your dentist or on the Internet for safe, qualified dentists and possible testing for sensitivity to dental materials.
Note: See Heavy Metal and Radiation detoxification information of our very first post of 2/14/13 here which includes a process to follow prior to having amalgam fillings removed.
