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.
A Moist towel placed over patient’s face during amalgam filling removal.
Drapes on the patient and gloves/masks of all staff be changed after removal is completed and before starting additional procedures.
Rubber dams used in the patient’s mouth to limit exposure, absorption or swallowing of amalgam filling material (containing mercury 50% at least) or other dental procedure materials.
Use of exhaust system to pull mercury vapor from the dental procedure room.
Whole office air ionizer and purifying system to remove dental chemicals.
Use of high-efficiency suction in the patient’s mouth during entire procedure to pull mercury and chemical vapors directly from the mouth (suction can be placed in the side of the mouth).
Oxygen delivered by nasal tubing to provide high-quality air during removal of fillings or other dental work.
Pure water to rinse mouth versus tap water (patient can bring own water to dental office).
Dental local anesthetic: Septocaine is recommended as a safe, injectable anesthetic for dental procedures. Avoid known carcinogenic agents such as Lidocaine and Carbocaine.
Replacement of amalgam fillings with low-fusing ceramics or ceramic/hybrids. (The LFCs [low-fusing ceramics] are a special, truly biocompatible, nontoxic dental restorative material which has a built-in shock-absorbing capacity to prevent cracking under maximum biting pressure. Especially avoid metal fillings, crowns, etc.)
Use of a laser to permanently bond a new inlay or crown. (If the dental restoration is not bonded by laser, the typical dental cements that are used will commonly wash out from underneath the crown or filling within about 5 years — eliciting slow decay underneath the crown or filling and more loss of the tooth. Laser bonding is permanent and will not do this.)
