Safer Mercury Amalgam Removal
At Anokhi Dental, we adhere to the Safer Mercury Amalgam Removal Technique (SMART) guidelines outlined by the International Academy of Oral Medicine and Toxicology (IAOMT)
Amalgam fillings, also known as “silver fillings”, are a type of dental material used to repair cavities caused by tooth decay. They have been used in dentistry for over 150 years and are known for their durability, strength, and cost-effectiveness.
The composition of amalgam fillings typically includes a mixture of metals such as silver, tin, copper, zinc and mercury. The mercury acts as a binding agent allowing the other metals to form a strong, solid filling material when mixed together. This mixture is then packed into the prepared cavity in the tooth and hardens over time.
Within scientific circles, there is a well- established awareness that amalgam fillings have the potential to release mercury. Ongoing discussion and research revolves around the extent of mercury release and its impact on health . It is known however, that the highest levels of mercury are typically released from amalgam fillings on both the day of placement and removal.
For these reasons we opt against using amalgam fillings. Furthermore, when removing such fillings, we implement specific measures to safeguard the wellbeing of both our patients and our team.
These measures include:
Rinsing with an activated charcoal mouthwash before and after removal.
Use of protective gowns and coverings.
Use of a latex-free rubber dam which creates a seal around the tooth being treated, isolating it from the rest of the mouth. This acts as a physical barrier, not only preventing accidental swallowing of particles but also minimising the inhalation of vapours released during the removal process. A saliva ejector is placed in the mouth under the rubber dam.
Placement of a sealed mask with a positive pressure air supply over the nose in order to minimise inhalation of mercury vapours.
Use of DentAirVac, a cutting-edge system designed to extract and filter potentially toxic vapors away from the immediate breathing area of the patient, dentist and dental assistant.
Use of a specific single-use drill to quickly and effectively cut the filling into chunks. This allows them to be removed in as large of pieces as possible, thereby minimising the release of vapours.
Use of a high speed suction and and abundant water irrigation with vigorous spraying to regulate the metal’s temperature and minimise vapourisation.
Ensuring adequate ventilation throughout the clinic and following specific protocols for the handling, storage, and disposal of dental waste containing mercury, ensuring compliance with environmental protection standards and occupational health and safety regulations.
