Filling Materials - What You Need to Know
Posted on 2/3/2025 by NC Pediatric Dentisty |
 We all know the importance of keeping our teeth healthy. But sometimes, even with the best care, teeth can develop cavities. When this happens, a filling may be necessary to restore the tooth and prevent further damage. But with so many different types of filling materials available, it can be difficult to know which one is right for you.
In this article, we will discuss the different types of filling materials, their pros and cons, and how to choose the right one for your needs.
Types of Filling Materials
There are four main types of filling materials:
| • |
Amalgam: Amalgam is a mixture of metals, including silver, tin, copper, and mercury. It is the oldest type of filling material and is still widely used today. Amalgam is strong and durable, and it can last for many years. However, it is also the most noticeable type of filling material, as it is silver in color. |
| • |
Composite: Composite fillings are made of a composite resin material, which is a mixture of plastic and glass. Composite fillings are tooth-colored, so they are less noticeable than amalgam fillings. They are also strong and durable, but they may not last as long as amalgam fillings. |
| • |
Glass ionomer: Glass ionomer fillings are made of a glass and acrylic material. They are tooth-colored and release fluoride, which can help to prevent cavities. However, they are not as strong as amalgam or composite fillings, and they may not last as long. |
| • |
Gold: Gold fillings are the most expensive type of filling material, but they are also the most durable. Gold fillings can last for many years, and they are very resistant to wear and tear. However, gold fillings are very noticeable, as they are gold in color. |
Choosing the Right Filling Material
The best type of filling material for you will depend on several factors, including the size and location of the cavity, your budget, and your aesthetic preferences. Your dentist will be able to help you choose the right filling material for your needs.
Here are some factors to consider when choosing a filling material:
| • |
Cost: Amalgam fillings are the least expensive option, while gold fillings are the most expensive. Composite and glass ionomer fillings fall somewhere in between. |
| • |
Durability: Amalgam and gold fillings are the most durable options, while glass ionomer fillings are the least durable. Composite fillings fall somewhere in between. |
| • |
Aesthetics: Composite and glass ionomer fillings are tooth-colored, while amalgam and gold fillings are not. |
| • |
Location of the cavity: Amalgam fillings are not recommended for use in the front teeth, as they are very noticeable. |
Caring for Your Fillings
Once you have had a filling placed, it is important to take good care of it. This includes brushing and flossing your teeth regularly, and seeing your dentist for regular checkups. With proper care, your fillings can last for many years.
Conclusion
Choosing the right filling material for your needs can be a difficult decision. But by understanding the different types of filling materials available and the factors to consider when choosing one, you can make an informed decision that is right for you.
