Dentists used metal in their dental work for centuries, and were still doing so only 25 years ago. However, research has shown that this practice is greatly damaging. The mercury and other metals used in dental work can have grave effects on health and cause many problems. Mercury is toxic, and its placement in the mouth can cause oxidative stress and nephrotoxicity, as well as cause a number of other health issues. Mercury usage in dentistry has been widely disputed.
Metal fillings are harmful for several reasons. They are unstable because temperature changes can greatly affect the metal, causing the tooth structure to weaken. This in turn can lead to bacterial infection and decay. Fractures and chipping can also occur during the filling placement because metal fillings require significant removal of tooth structure.
Metal-free dentistry has significant advantages and is therefore quickly replacing the practices of earlier days. Dentists use composite fillings made of resin from glass or plastic. These resin fillings are more attractive because they are the same color as natural teeth, and they are also much more safe and beneficial.
Composite fillings are very strong compared to their metal counterparts. They are also much better at repairing teeth because they have adhesive properties that allow them to keep the tooth structure in place without necessitating the excessive removal of tooth. These fillings cost less and take less time to place, and don’t cause gum disease or discolor teeth.
Zirconia crowns are another advantageous form of metal-free dentistry. They are made from zirconium, making them strong and long-lasting. They are aesthetically pleasing because they are tooth-colored, don’t require significant removal of tooth structure, can be modified, and are biocompatible. They are stronger than porcelain crowns, which often can chip.
Metal-free dentistry is highly flexible. Composite fillings are useful for other dental practices such as the repair of chipping, breaking, and wear and tear. They aid in maintaining the integrity of tooth structure, look more natural, and don’t have toxic properties and effects.
