What Do Dentists Use to Fill Cavities?

Many people feel uneasy when they hear they have a cavity. They often wonder what dentists use to fill cavities and whether the material is safe and long lasting. At Desert Lake Family Dentistry in Avondale, AZ, we explain every step so you feel informed and prepared. Here we tell you all about the materials we use and how they protect your tooth.

Different Types Of Dental Fillings

There are different types of tooth fillings in Avondale, and each one serves a specific purpose. Knowing the types can help you understand your options and feel more confident about your treatment. Some materials focus on strength, while others focus on a natural look. Below, we tell you about the main types of fillings and how each one works to protect your smile.

Composite Resin

Composite resin is a tooth-colored material that blends with natural enamel. Dentists place it in layers and use a special light to harden it. This material bonds tightly to the tooth, which helps support the remaining structure. Many patients choose composite because it looks natural and works well for both front and back teeth.

Dental Amalgam

Dental amalgam is a silver-colored material made from a mix of metals. Dentists have used it for many years because it is strong and durable. It handles heavy bite pressure well, especially in back molars. It is a good choice in the following cases:

• Large cavities in back teeth
• Patients with strong bite force
• Areas that are hard to keep dry during treatment
• When a lower-cost option is needed

Ceramic or Porcelain Fillings

Ceramic fillings match natural teeth very closely. They resist stains and last many years with proper care. Dentists often recommend ceramic for larger cavities or when extra strength is needed. This material provides both durability and a natural appearance.

Glass Ionomer

Glass ionomer contains fluoride, which helps protect the tooth from future decay. The best dental experts in Avondale, AZ, often use it for small cavities or for children. It may not last as long as composite or ceramic, but it works well in specific areas of the mouth.

How Dentists Choose the Right Filling Material

Dentists at Desert Lake Family Dentistry do not choose a filling by chance. Dr. Shayegan carefully examines each tooth before deciding what dentists use to fill cavities. He reviews several important details to select the best material for long-term protection.

He looks at:

• The location of the tooth
• The size of the cavity
• The amount of bite pressure in that area
• Whether the tooth is in the front or back
• Habits like teeth grinding
• Medical history
• Cost and insurance coverage

Back teeth need strong materials because they handle heavy chewing force. Front teeth need materials that match natural tooth color. Digital X-rays help Dr. Shayegan see how deep the decay extends. This careful evaluation helps ensure the filling protects the tooth for many years.

How Long Do Different Types of Fillings Last?

Many patients want to know how long a dental filling will last. The lifespan depends on the type of material and how well you care for your teeth. Some materials last longer than others, but daily habits play a big role in durability. Here is a simple guide:
