If you have a cavity that requires a dental filling, there are several different types of materials that can be used such as amalgam, gold, porcelain, and composite. Here, our Grande Prairie dentists explain the differences between the different materials to help you decide which might be better for you.
Fillings for teeth can be made from a variety of materials, including amalgam, porcelain, gold, and composite resins. In addition to being safe and long-lasting, each of these materials has its own set of advantages and disadvantages.
Composite Fillings
Composite fillings are tooth-coloured fillings made of plastic materials that closely resemble the natural appearance of your teeth when placed in your mouth.
These fillings are designed to blend seamlessly with your natural teeth, as they are made to match their colour. They are also flexible and can be easily shaped and molded onto your teeth. Additionally, composite fillings bond naturally to the tooth structure, reducing the amount of enamel that needs to be removed during the preparation process.
The placement of a composite filling involves removing the decayed portion of the tooth and applying a bonding material to the cavity. Layers of composite resin are then applied and hardened with a curing light. Once the final layer has hardened, your dentist will shape the filling to match the contours of your natural teeth.
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.
Porcelain Fillings
To create a durable dental restoration that matches the natural color of your teeth, a combination of porcelain and metal is used.
The process involves having a porcelain filling custom-made in a dental laboratory. Once it is ready, you will visit your dentist for the placement of the filling. Typically, this procedure requires two or more dental appointments to complete. During the final appointment, the porcelain filling will be permanently cemented in your mouth.
Gold Fillings
In order to create a cast gold filling, a model of your tooth is necessary. A blend of gold and other metals like silver and copper is used to craft these restorations.
Similar to porcelain fillings, cast gold fillings are fabricated in a dental laboratory and then delivered to your dentist for placement. This process usually involves multiple dental appointments to complete. During the final visit, the cast gold filling is securely cemented in your mouth.
