Breaking Down the Different Types of Dental Fillings
Over 90 per cent of people in North America have a fillings. Essential for restoring the function and integrity of a tooth affected by decay or damage, fillings are the most common procedure we do at our office. However, not all fillings are created equal.
Let's explore the different types of dental fillings available, each with its unique benefits and considerations.
Amalgam Fillings
Amalgam fillings, also known as silver fillings, have been used for over a century. They are composed of a mixture of metals, including silver, mercury, tin, and copper. Amalgam fillings are known for their durability and strength, making them suitable for filling large cavities in molars where chewing pressure is highest.
They are also cost-effective. However, their metallic colour can be noticeable, which is why they are less commonly used for visible teeth.
Composite Fillings
Composite fillings, or tooth-colored fillings, are made from a mixture of plastic and fine glass particles. They are popular due to their ability to match the natural colour of the tooth they’re in, providing a more aesthetically pleasing result.
Composite fillings bond directly to the tooth structure, which can help strengthen the tooth. While they are not as durable as amalgam fillings, advancements in dental materials have significantly improved their longevity. Composite fillings are ideal for small to medium-sized cavities in visible areas of the mouth.
Ceramic Fillings
Ceramic fillings, often made of porcelain, are another aesthetically pleasing option. They are highly resistant to staining and wear, making them a durable choice for visible teeth.
Ceramic fillings are custom-made in a dental lab and then bonded to the tooth. This process can make them more expensive and require multiple visits to the dentist. However, their natural appearance and durability make them a preferred choice for many patients.
Glass Ionomer Fillings
Glass ionomer fillings are made from a mixture of acrylic and a specific type of glass. They are often used for fillings in children’s teeth and in areas not subject to heavy chewing pressure. One of the unique benefits of glass ionomer fillings is their ability to release fluoride, which can help protect the tooth from further decay. However, they are less durable and more prone to wear and fracture than other filling materials.
Gold Fillings
Gold fillings, or inlays, are highly durable and can last for many years. Made from a gold alloy, these fillings are custom-made in a lab and then cemented into place. They are biocompatible and cause minimal wear to surrounding teeth.
However, gold fillings are expensive and require multiple dental visits to place. Additionally, their metallic colour is not suitable for those seeking a natural-looking filling.
The right filling for you
Choosing the right type of dental filling depends on various factors, including the location and size of the cavity, aesthetic preferences, and budget. Discussing these options with your dentist can help you make an informed decision that best suits your dental needs and ensures a healthy, beautiful smile.
