If you've got a cavity that needs a dental filling, there are several types of materials that may be used to perform the task. Porcelain, composite, gold and amalgam are some of the most commonly used filling materials. Here, our Pembroke and Deep River dentists discuss the differences between them to help you decide which may be better for you. 

Fillings for teeth can be comprised of a variety of materials, including porcelain, composite, gold and amalgam resins. Along with being safe and long-lasting, each of these materials has its own advantages and disadvantages. 

Composite Fillings

These plastic tooth-coloured fillings look and feel natural when placed in a patient's mouth. Composite fillings are the same colour as your natural teeth, allowing them to blend in seamlessly with the rest of your smile. These materials are also relatively easy to shape and mould onto teeth. Your dentist will not have to remove as much existing enamel during the preparation process since these fillings bond naturally to teeth. 

To place this type of filling, your dentist will first remove decay from the tooth before applying bonding material to the inside of the cavity. Thin layers of composite resin are then poured into the hole. Each layer hardens to a solid state with the help of a curing light. When the final layer of the filling has hardened, the dentist will shape the filling so that it matches the shape of your natural teeth. 

Porcelain Fillings

A strong, tooth-coloured dental restoration is created by combining hard and brittle porcelain fillings with metal, which results in a tooth-coloured dental restoration.

A porcelain filling is created in a dental lab and returned to your dentist, who cements it in place in your mouth. It is typically necessary to schedule at least two dental appointments in order to complete the procedure.

Amalgam Fillings

Silver in colour, amalgam fillings are frequently used to fill teeth located at the back of the mouth. They are a mixture of metals, including mercury, silver, copper, and tin, among others.

While the silver colour may not be appealing to people who prefer a more natural appearance, they are a long-lasting option for molars that are subjected to a great deal of wear and tear.

Gold Fillings

In order to create a cast gold filling, a model of your tooth must be created. A mixture of gold and other metals, such as silver and copper, is used to create these pieces.

Much like the porcelain fillings, this type of dental filling is made in a dental lab and then returned to your dentist, who cements it into place inside your mouth. As a result, this type of filling typically requires at least two dental appointments to complete.
