Cary Dentist Office - Dental Fillings

Most people experience dental decay at some point in their lives, which is why dental fillings are a very common procedure that our team specializes in. However, tooth decay has a nasty habit of going unnoticed, so there are lots of people who need dental fillings, but never get them. Fillings are an important part of preventing the spread of harmful bacteria, so make sure to visit the dentist regularly to ensure that a dental filling is not needed.

Types of Dental Fillings

Dental fillings are used to restore a tooth’s structural integrity and functionality. They replace the damaged or decayed portion of a tooth to make the tooth whole and completely usable once more. Fillings also stop the process of decay itself, which prevents your tooth from having to eventually be removed.

There are many different types of dental fillings:

  • Composite Fillings
  • Ceramic Fillings
  • Gold Tooth Fillings
  • Silver Tooth Fillings

Typically, we recommend composite fillings because they match the color of the tooth that they will be placed on. This type of filling has the appearance that no filling was ever done, restoring the original look of the tooth.

What Are Dental Fillings Made Of?

Nowadays, dental fillings are made from numerous materials. the most commonly used materials are porcelain/ceramic, silver amalgam, composite resin, and tooth-colored plastic.

Porcelain Dental Fillings

Porcelain dental fillings, also often referred to as ceramic fillings, are designed specifically match the color of the teeth they’re fused on. The main benefit of porcelain fillings is the fact that they can be created in very precise colors that look cosmetically-pleasing, unlike fillings made out of composite resin or metal-based materials (silver and gold are primary examples of  metal-based filling materials.) These types of fillings are often requested and have a much more visually appealing appearance compare to other types. Along with that, they’re also considered extremely durable and capable when installed correctly (they have been known to last up to 20 years), have outstanding resistance to stains and abrasions, and are much less toxic and allergenic than metal-based fillings.

Silver Amalgam Fillings

Made out of a mixture of minerals such as tin, silver, zinc, and copper, these are the most widely-known types of fillings. They’re very cost-effective, have been known to last up to 15 years, and are typically easy to implement. The main disadvantage of silver amalgam and other metal-based fillings is, as mentioned above, is the fact that they are not visually appealing and are highly visible. Another disadvantage of these fillings is the fact that they have been known to expand and contract over time. This has resulted in teeth cracking which can allow bacteria and food particles to be trapped in the aforementioned cracks, and, thus, enable additional cavities to form. 

Composite Resin Fillings

Composite resin fillings consist of plastic and resin material that is added on top of a cavity before it hardens. After placed in the necessary areas, it is hardened by using a blue curing light. These types of fillings are able to be color-matched but do not last as long as other filling alternatives. 

Dental Fillings Procedure

The process of getting a dental filling is very simple and relatively painless. There are two steps in this procedure: The first is to prepare the tooth for the placement of the dental filling. This is usually done by removing the existing decay and thoroughly cleaning the affected area. The second and final step is to fill the tooth with a restorative material, usually made from a composite resin, or “tooth-colored filling.” Be sure to check out our general dentistry FAQ page to learn more about how dental filling services.
