Types of Teeth Filling for Cavities and Tooth Decay

Types of Teeth Filling for Cavities and Tooth Decay

July 13, 2023

Cavities and tooth decay can cause significant discomfort and even lead to tooth loss. Fortunately, getting dental fillings near you can treat cavities and prevent further decay. There are several types of teeth-filling materials available. The filling material choice depends on the cavity’s location, size, patient’s oral health history, and personal preferences.

What are Cavities and Tooth Decay, and How can Filling Help?

Cavities and tooth decay can erode the enamel and create small holes or cavities in the tooth. They can lead to more significant decay, infection, and tooth loss. Dental fillings in Detroit, MI, are a common and effective treatment option for cavities and decay.

Dental fillings serve two main purposes in the treatment of tooth decay. First, they help restore the affected tooth’s structure and function. When tooth decay progresses, it creates cavities or holes in the tooth structure. Fillings are used to fill these cavities, restoring the tooth’s shape and integrity. By sealing off the cavity, fillings prevent bacteria and food particles from entering and causing further decay.

Second, fillings help to prevent the spread of decay. Tooth decay is a progressive condition, and if left untreated, it can advance deeper into the tooth, potentially reaching the pulp, where the nerves and blood vessels are located.

Types of Teeth Filling & When to Use Them

The type of teeth fillings include:

  • Composite Resin Fillings

Composite tooth fillings, also known as tooth-colored or white fillings, are a popular dental therapeutic option for treating tooth decay. The primary advantage of fillings is that they match your natural teeth. They can be customized to blend seamlessly with the surrounding tooth, making them an ideal choice for visible areas of the mouth. Additionally, they require less removal of healthy tooth structure compared to amalgam fillings, as they bond directly to the tooth, providing better support and reducing the risk of tooth fractures.

  • Amalgam Fillings

Amalgam fillings combine different metals, including silver, mercury, tin, and copper. Therefore, these restorations are sturdy and suitable for restoring teeth in areas that endure heavy chewing forces, such as molars. Another advantage of amalgam fillings is their cost-effectiveness, as they are less expensive than other filling materials.

However, one notable drawback is their silver color, which can be visually noticeable, especially on the front teeth.

  • Gold Fillings

Gold fillings are expensive and durable types of fillings available. They are long-lasting and withstand heavy chewing pressure, making them a good choice for larger cavities and back teeth. They are also biocompatible and less likely to cause allergic reactions or sensitivity. However, gold fillings are costly and may not be covered by insurance, making them less accessible for some patients.

  • Ceramic Fillings

Ceramic fillings, also known as porcelain fillings, are made of a tooth-colored material that is custom-made to match your teeth. Ceramic fillings are strong and resistant to staining, ideal for larger cavities and back teeth. They are also biocompatible and less likely to cause allergic reactions or sensitivity. However, ceramic fillings are more expensive than composite resin fillings and may require more than one dental visit to complete.

  • Glass Ionomer Fillings

Glass ionomer fillings are a mixture of glass and acrylic and are often used for small to medium-sized cavities in children or as temporary fillings. They release fluoride over time, which can help prevent further decay. Glass ionomer fillings are also biocompatible and require less drilling of the tooth than other fillings.

What Can You Expect During The Procedure

A dentist near you will typically numb the gums to reduce pain. The dentist will remove the decayed part and shape the cavity.

Once the filling material is in place, the dentist will check the bite to ensure proper alignment and make any necessary adjustments. They may also polish the filling to smoothen any rough edges and make it blend seamlessly with the natural tooth structure. The dentist will provide instructions and guidance on oral care post-treatment throughout the procedure.

After the procedure, patients may experience temporary numbness, which will gradually wear off. It is common to feel slightly sensitive to hot or cold temperatures or experience mild discomfort, which usually subsides within a few days.


Dental fillings repair cavities and prevent further tooth decay. With various filling materials available, patients can choose one suitable for durability, aesthetics, and cost.
