Dentists who advocate removal of amalgam fillings often recommend wearing breathing apparatus, using high-volume aspiration, and performing the procedure as quickly as possible. Sources of mercury from the diet, and the potential harm of the composite resins to replace the purportedly harmful amalgam fillings, may also need to be considered. [76]
To fabricate an amalgam filling, the dentist uses a mixing device to blend roughly equal parts (by mass) of shavings of a silver-base alloy with mercury until the shavings are thoroughly wetted. The silver alloy is typically 40–70% Ag, 25-29% Sn, 2–40% Cu and 0–2% Zn (when the alloy is formulated Zn is a scavenger and is mostly consumed ...
Hal Alan Huggins (1937 – November 29, 2014) was an American alternative dentistry advocate and campaigner against the use of dental amalgam fillings and other dental therapies that he believed to be unsafe. [1] [2] Huggins began to promote his ideas in the 1970s and played a major role in generating controversy over the use of amalgam. [3]
Amalgam is a metallic filling material composed from a mixture of mercury (from 43% to 54%) and a powdered alloy made mostly of silver, tin, zinc and copper, commonly called the amalgam alloy. [16] Amalgam does not adhere to tooth structure without the aid of cements or use of techniques which lock in the filling, using the same principles as a ...
There has been some controversy regarding the use of amalgam fillings by dentists, [7] because the amalgam contains mercury. Some forms of mercury are toxic to humans, but the NCAHF cites the CDC in stating that there is no evidence that "the health of the vast majority of people with amalgam is compromised" or that "removing amalgam fillings ...
Dental amalgam is a mercury-containing filling material used to fill cavities once tooth decay has been removed. [20] [21] Due to prolonged practice in the field of dentistry and working with amalgam there is a significant exposure to mercury among professionals. [22]
Composites and amalgam are used mainly for direct restoration. Composites can be made of color matching the tooth, and the surface can be polished after the filling procedure has been completed. Amalgam fillings expand with age, possibly cracking the tooth and requiring repair and filling replacement, but chance of leakage of filling is less.
Dentists who remove amalgam fillings using the Safe Mercury Amalgam Removal Technique (SMART) technique give the patient "a slurry of charcoal, chlorella, or similar adsorbent to rinse and swallow before the procedure (unless the patient declines or there are other contraindications making this clinically inappropriate)".
