What Are Composite Fillings?
Composite fillings are tooth-colored restorations used to repair cavities, minor cracks, and other small areas of tooth damage. As a form of restorative dentistry, composite fillings use a tooth-colored resin material to replace damaged tooth structure and restore the tooth’s shape and function. After removing decay and preparing the affected area, the dentist bonds the composite material to the tooth, helping seal the cavity and protect the remaining structure from further damage.
Dental Fillings are commonly used to:
- Repair cavities caused by tooth decay
- Address tooth sensitivity related to enamel damage
- Restore small cracks or worn areas
- Protect teeth from worsening damage
Composite vs. Amalgam Fillings
Modern dentistry offers different filling materials, and our practice focuses on conservative, tooth-friendly options.
Composite (Tooth-Colored) Fillings
- Designed to blend naturally with your tooth
- Bond directly to the tooth for added strength
- Preserve more natural tooth structure
- Free of metal and mercury
Amalgam (Silver) Fillings
- Made from a mixture of metals
- More noticeable in appearance
- Less commonly used in modern dentistry
At Darren Gonzalez DDS, we primarily offer composite, tooth-colored fillings to support both function and aesthetics.
