Dental amalgams are an exceptional material that has allowed great progress in the world of dentistry. While they represent such important progress, they have also become a matter of great debate. Mercury in dental fillings is believed to cause central nervous system complications, a general worsening of well-being in some patients, and Alzheimer's. The dental industry should incorporate safer filling materials for patients. In this article we will take a look at the history of silver amalgam and see both negative and negative views on this issue. Throughout the history of dental medicine dentists have searched for the perfect material to help treat the most common problem in people's mouths and cavities. The material would also be useful for repairing chipped and broken teeth. The dentist needed a material that was resistant, relatively low cost, easy to apply, durable and capable of limiting the growth of bacteria. In the early 19th century in France dentists found their miracle material and that material was amalgam. Dental amalgam is made of a mixture of mercury and at least one other metal such as zinc, copper, tin or silver. Combinations of these metals are the foundation of what gives silver amalgams their strong structure and lustrous metallic appearance. The first use of amalgams in dentistry is still quite unknown to researchers, but it is claimed that it may have been dated as far back as 659 AD in China. Before the discovery of amalgam, the dentist tried all kinds of materials to help in the restoration of teeth. Stone chips, resin, cork, gum, turpentine, lead, and gold were some of the first materials that were boiled and poured onto teeth to create fillings. A dentist named Louis Regnart had the brilliant idea t...... halfway through the document ...... we have seen the negative opinions of this debate we will take a look at the null opinions on amalgam dentistry. As previously stated, over 90% of people have traditional dental amalgams that contain the toxic element mercury. While there may be a chance of experiencing serious side effects, many of us have not experienced any. Although mercury is the main component of dental amalgam and has been linked to several diseases, there is still no solid health consensus that it is the main culprit. Cases of people suffering adverse symptoms and blaming mercury exposure may have other factors to place the real blame. Mercury can be found in abundance throughout our atmosphere. We receive doses of mercury every day from the air, from foods such as fish and from water. Although these dosages of mercury are minimal and cause little to no effects on our body.
