The Genesis of the MSafe™ Oxygen Breathing System

We were taught that these fillings were safe because the resulting mixture, called an  “amalgam,” was solid with no free mercury, therefore safe to be used for dental fillings. As time went by, certain dentists were proclaiming that these fillings were not safe, stating that mercury vapor continuously escapes from them.  Most of the dental profession at that time viewed these dentists and scientists as pariahs; in fact these individuals were more or less blacklisted and actually lost their dental licenses for promoting that idea. I started looking at the science that these dentists were using to substantiate their claims, and discovered that mercury vapor is in fact a potent neurotoxin, and that any amount in the body can be deleterious, especially developing children, those with a compromised immune system and pregnant women. Mercury vapor does continuously escape from these fillings, and even more so when agitated, such as from warm liquids and a tooth brush. I have some extracted teeth with these fillings that have been in a jar for decades, and a mercury analyzer registers mercury vapor still coming off them, and can triple or quadruple in amount when brushed with a tooth brush or placed in warm water. It is interesting that many in the dental profession still believe that these fillings can do no harm.

As a scientific data source that influenced my view regarding the relative safety of these fillings, I reviewed information that is readily available through the International Academy of Oral Medicine and Toxicology (IAOMT), an organization of professionals dedicated to analyzing and developing protocols having to do with dental patient safety in the areas of techniques and materials used in the mouth. The organization is not only against usage of the material with much scientific data to back their claims, but also has a protocol for dentists to follow in removing them safely. During the process of their removal with a drill, the filling material flies everywhere, along with toxic mercury vapor. This can be dangerous for the patient, but especially for the dentist and assistant, as they remove these fillings on a continual basis. It can also be deleterious for all others in the office, as the air of dental vacuum systems carrying the mercury vapor exhausts back into the office, unless otherwise vented.

The IAOMT recommendations for safety for all within the dental office is now embodied within their Safe Mercury Removal Technique (SMART) protocol with a certification program to guide dentists towards optimum safety that includes course work and passing a comprehensive test.

Years ago, when I started using the IAOMT protocol, it consisted of several safety precautions, including the patient breathing pure oxygen through a nasal mask used for nitrous oxide/oxygen sedation. Besides the possibility of the masks not adequately keeping out surrounding air, the oxygen supply tubes cinched the patient’s head to the dental chair, disallowing patient head rotation which is needed for the dentist to access, view and treat the more difficult back areas of the mouth.  For the dentist and assistant, the recommendation was the wearing of Hazmat masks that completely encapsulate the head with a filters jutting from its front. These masks were cumbersome and disallowed the usage of my special magnification glasses and their attached auxiliary lighting that allow me to provide my best in the detailed shaping and treatment of my patient’s teeth. It also wasn’t a favorite with dental assistants, as it definitely would re-arrange a hairdo. I started thinking that, in many ways, the oxygen breathing arrangement for the patient was a better deal for them than it was for the doctor and assistant. I started thinking of how I could develop a 3-way oxygen breathing system that would be optimum for the three of us. I began purchasing parts off the internet, and through trial and error, over the course of a dozen or more years, developed a system that offers safe breathing, unaffected vision for doctor and assistant and better access to the patient’s teeth as it allows for patient head rotation.

Little did I know back then that this would ultimately lead to the MSafe Oxygen Breathing System. When used along with the other SMART protocol precautions, the patient, doctor, assistant, and all in the dental office can be confident that they are in the safest of environments.




Dr. McBride is an excellent dentist. Thank you for my safe mercury filling removal!! Dr. McBride was awesome and made my son and I feel comfortable.
