The use of dental Amalgam is becoming controversial due to its contents of mercury, its "semi-permanent" properties, and its known ability to dry, crack, or fracture teeth that it is filling. Though these properties of Amalgam are known, it is still used as a primary filament for teeth by many dentists. This is in part due to its semi-permanent properties which cause the Amalgam to fail after a number of years. This failure requires replacement and thus the dentist makes more money. Instead of using Amalgam, dentists should begin using only porcelain or gold inlays. Dentists should be focusing on the patient's satisfaction rather than their own bank account...

THE USE OF DENTAL AMALGAM HAS BECOME CONTROVERSIAL IN DENTISTRY
Most people know that, but they remain unaware of the most important details.
The controversy revolves around mercury, and rightly so, as mercury is a major component of dental amalgam.
Early in my practice, my concerns about dental amalgam were raised after observing that the material is only semi-permanent.
It is clear that even excellently placed dental amalgam restorations (fillings) begin to show signs of failure after as little as 5-8 years. Most dental amalgam restorations definitely need to be replaced after 10-15 years due to material failure. Now, why would any dental doctor want to provide a dental restoration that has “built in” material failure happening in as little as 5-8 years? The material, in my opinion, desiccates (dries out) teeth making them more brittle and prone to cracks and fractures. Several times every month, I see patients who suffer from broken teeth that have dental amalgam restorations.
But the most important concern with dental amalgam is the mercury.
