Understanding Amalgam Fillings

Among the biggest and most lingering disputes in the world of dentistry revolves around amalgam fillings and their mercury content. Though the toxic nature of mercury is well known, there is no documented proof that the contamination of patients who have amalgams containing mercury suffer ill-effects. Exposure to both large and small amounts of mercury through amalgam fillings is held responsible for the onset of diseases like mental and autoimmune disorders.

Dentists will continue to use these types of amalgams until such time as reliable research can be provided to back up these claims. No international health body or individual dentist has to date found any cause for alarm regarding the wellbeing of patients who have had their cavities treated with amalgam fillings.

They are popular restorations because they are easy to apply, they resist wear and tear (even when in the heavy working molars) and they’re relatively inexpensive materials.

Other shortcomings of using amalgam fillings are the larger amount of tooth material that has to be drilled out to correctly fit them in, and the attention they draw to a patient’s teeth because of their dark grey color. Many people with amalgam fillings complain of increased sensitivity when they have this type of filling placed, but most state that this diminishes and disappears after a few days.

Teeth receiving amalgam fillings require preparation with dental adhesives and resins, and then sealing with special lighting device. Because amalgams are much less complicated, their ease of application and durability makes them more appealing to patients who do not like to spend time in the dentist’s chair. Most people discover they need fillings after a routine exam or because of pain or discomfort in a specific tooth or area of the mouth.

If expenses are a problem, patients should go with amalgam fillings, but if looks are of greater importance, then composite fillings which closely resemble natural teeth are a much better alternative.

A final consideration about the selection of amalgam fillings over composite filings involves dental insurance: Most dental insurance providers offer full coverage of the less expensive amalgam fillings, while not all will cover the more costly, but equally affective composites.

The patient and dentist must discuss and decide on the wisest choice according to a patient’s needs and budget.
