Metal Filling
Metal filling is commonly used for both aesthetic and restorative purposes in dentistry. Metal fillings are made from amalgam, a combination of metals including silver, copper, zinc and mercury. This type of filling is strong, durable, and long-lasting, making it a preferred filling material among dentists. In the past, metal fillings were the most commonly used type of filling material. However, advances in dental technology now allow for more aesthetically-pleasing and natural-looking materials, such as composite resin, to be used.
Metal fillings are typically recommended when replacing large, broken down fillings or when the area to be filled is located in a difficult to reach area of the mouth. Metal fillings are able to withstand extreme biting force, making them an ideal choice for molars and areas of the mouth which experience a lot of chewing. Metal fillings do not corrode, shrink, or discolor with time and are able to last for many years with proper maintenance and care.
Metal fillings are relatively easy to apply and dry quickly. Once the decay or cavity is removed, the metal filling can be placed, molded, and shaped on the tooth. It is then hardened with a curing light and polished. Metal fillings are strong, long-lasting, and cost effective. However, they may attract noticeable attention due to their darker, metallic color compared to composite fillings and cannot be used for filling front teeth.
In recent years, composite fillings have become increasingly popular due to their natural, tooth-like color. Composite fillings are made from a mixture of acrylic resin and powdered glass particles and are able to be matched to the shade of the patients teeth. These fillings are more resistant to staining and discoloration and are better suited for front teeth and areas which are more visible. They can also be used to repair smaller cavities and may even prevent further damage by protecting the weakened tooth structure.
While metal fillings have many benefits, they are not the best option for every situation. If you have an aging metal amalgam filling that needs to be replaced, your dentist may recommend a more aesthetically pleasing material such as composite resin. Whatever filling material you choose, proper maintenance and care are essential for keeping your teeth healthy and looking great!
