Dr. Todd Pizzi, DDS Explains Filling Choices

Oct. 29, 2013 - PRLog -- Recently, I discussed the importance of getting cavities filled to avoid the spread of tooth decay and more widespread infection that can lead to an impact on overall health. What many people don't realize is that there is a wide range of options available today for filling cavities. When it comes to fillings, it's not just a mouthful of silver anymore.

Once upon a time, fillings were made primarily of metal. Dentists in the early 1800s experimented with different fillings containing gold, platinum, silver, and even lead. More experimentation tinkered with materials like tin and aluminum. Lead was eventually phased out as awareness grew concerning its harmful effects on the body. And eventually, in the mid-nineteenth century, the era of amalgams was born.

Amalgam

Modern dental amalgams are comprised of several types of metal, including silver. Amalgam fillings are durable and dentists can easily mold the fillings to the individual shape of teeth so that the material doesn't hamper chewing or talking. A drawback to amalgam fillings is that the materials they are made of can expand and contract more than some other filling materials, occasionally causing a tooth to fracture. Also, dental amalgam also contains mercury in it which some people believe can cause health problems. Amalgam has been widely used for fillings, but nowadays, patients have several other options as well.

Gold

Although it is quite durable, gold can be an expensive alternative to amalgam. Patients may opt for gold because they prefer its "look" to the silvery color of amalgam. However, gold is much less commonly used than amalgam.

Composite Fillings

Composite resin "tooth-colored" fillings are popular because their color can be matched to the patient's tooth color. This can be especially appealing if the filling is on part of a tooth that is visible when a patient smiles. The material actually bonds to the tooth structure for a more seamless look. Composites are used not only for fillings, but also to repair chipped or cracked teeth. Composite fillings wear out faster than amalgam fillings and can sometimes chip, depending on where they are positioned. They are also slightly more expensive than amalgam fillings and take a bit longer, but are a highly popular alternative due to their aesthetics.

Ceramics

Porcelain fillings are another aesthetically pleasing filling option. While a bit on the expensive side, they blend well with the natural color of the tooth and are resistant to staining. Although ceramic fillings are durable, they are typically better suited for large areas of the tooth.

Glass Ionomer

Made of a blend of glass and acrylic, glass ionomer fillings are less noticeable than metal fillings, but don't match tooth color quite as well as a composite filling. They are also less durable than other types of fillings and are sometimes used for children's fillings – an advantage is that they release fluoride, which enhances protection in an already vulnerable tooth.

As you can see, there are a lot of options to choose from when it comes to filling a cavity. I enjoy working closely with my patients to see their dental needs met, and fillings are no exception. I'm always happy to discuss the options that will best provide my patients with a healthy, happy smile.
