A Guide to Types of Materials in Dental Fillings

If you need a dental filling, you might be surprised to learn that several different materials can be used—each with its own advantages. At our general dental practice in Irvine, we take the time to help patients understand their options so they can choose the right solution for their needs, lifestyle, and budget. Here’s a helpful guide to the most common types of dental filling materials.

Composite Resin Fillings

Composite resin is one of the most popular choices for dental fillings today. Made of a tooth-colored mixture of plastic and fine glass particles, composite fillings blend in naturally with your existing teeth. This makes them a great option for visible areas like front teeth.

Pros:

• Aesthetically pleasing
• Bonds directly to tooth structure
• Preserves more of the natural tooth

Cons:

• May not be as long-lasting as metal fillings for large cavities
• Can be more expensive than other materials

Amalgam Fillings (Silver Fillings)

Amalgam fillings have been used for over a century and are made from a blend of metals, including silver, tin, copper, and mercury. Though less common today, they are still valued for their durability and cost-effectiveness, especially for molars that endure heavy chewing pressure.

Pros:

• Very durable and long-lasting
• Less expensive than composite
• Quick to place

Cons:

• Noticeable silver color
• May cause slight expansion over time, potentially cracking the tooth

Ceramic Fillings (Porcelain)

Ceramic or porcelain fillings are typically used for larger restorations or inlays/onlays. They’re custom-made in a lab and bonded to the tooth, offering a highly natural look.

Pros:

• Extremely durable and stain-resistant
• Matches natural tooth color beautifully
• Biocompatible and non-reactive

Cons:

• More expensive than other types of fillings
• Requires more than one dental visit in most cases

Gold Fillings

Gold fillings are less common today but still chosen by some for their longevity and biocompatibility. These are made from a gold alloy and are usually placed in back teeth.

Pros:

• Exceptionally strong and long-lasting
• Won’t corrode
• Gentle on opposing teeth

Cons:

• Very noticeable in appearance
• Higher cost
• Requires at least two appointments

Which Filling Material Is Right for You?

The best filling material depends on several factors—where the cavity is located, how large it is, your aesthetic preferences, and your budget. During your visit, your Irvine dentist will walk you through the pros and cons of each option and recommend what best suits your situation.
