What are they, what are they made of? Are they safe for health?
Have you ever had a filling? Surely the vast majority do, since to a greater or lesser extent, almost all of us have had a tooth decay on occasion.
If so, you know that it can be silver or white like the teeth, much more aesthetic.
The first are silver amalgam fillings, currently in disuse among dentists in favor of the composites used today. Despite this, obviously, there are still many people who carry them in the mouth.
But, do you know what they are and what silver amalgams are made of? Today we explain it to you.
What are they
An amalgam is one of the materials that can be used to rebuild teeth. Actually it is an alloy of silver, mercury, copper and tin that are used to fill the cavities caused in a healthy tooth when attacked by caries, so that the piece can recover both its masticatory function and its aesthetics.
Another option to treat teeth with caries is the composite, setrt of synthetic resins that are used regularly today to restore the affected teeth of caries in an effective way and presents a series of differences against amalgams.
Dental reconstructions made of silver amalgam tend to be more resistant and durable in the mouth than composite ones, lasting the first 30 years compared to the ten that usually last the second. They have a bacteriostatic effect and support loads, being used successfully for more than 150 years.
In addition, since they are deprecated, their cost is lower.
The aesthetic component is very important in a healthy mouth. At this point, the composite, given its white color, similar to that of natural teeth, gains in aesthetics and naturalness against amalgams, with its silver color, which evidences them much more, since they blacken in contact with saliva.
Another important issue to consider in the use of silver amalgams is their mercury content, which is why safety for the patient has been repeatedly questioned.
However, after years of reviewing numerous scientific studies, the United States Food and Drug Administration (FDA) concluded that dental amalgams are safe and effective for the use of dental restorations and catalogs in it class that gold fillings and composite fillings.
Similarly, the European Scientific Committee on Emerging and Recently Identified Health Risks (SCENIHR) and the Scientific Committee on Health and Environmental Risks (SCHER) consider that environmental risks and indirect exposure of denatured mercury in humans from the use of Dental amalgam are much lower than tolerable limits, indicating the low risk of serious health effects.
Specifically, WHO says: “Dental amalgam is a potentially important source of exposure as it can contain up to 50% of elemental mercury. It is released as vapor, ions or fine particles and can be inhaled or ingested. Although no adverse effects have been demonstrated. for health, the use of dental amalgam is rapidly decreasing. Amalgam may also pose a occupational risk to dentists and may cause the release of mercury into the atmosphere during cremation. ”
A different matter is whether the patient in question suffers from any type of allergy or sensitivity to any of the metals that the amalgam contains. In such a case, it is evident that its use would only harm the patient, causing adverse contact reactions in the oral cavity.
In any case, although it has been shown that silver amalgams, with the exception of sensitive or allergic patients, do not pose any health hazard, there is a growing number of patients who opt for a Holistic Dentistry option for It is useful to know that there are alternative materials such as composites that are currently used. Its resistance and durability is proven, they do not use metals and its white color gives it an aesthetic component that amalgams lack.
