Dental fillings are a widely used restorative dental treatment designed to repair teeth affected by decay, fractures, or wear. By filling in cavities and minor damage, fillings restore function, protect teeth from further deterioration, and enhance oral health.

At Pecan Tree Family Dentistry, we offer high-quality, durable, and aesthetically pleasing fillings tailored to each patient’s needs.

Why Are Dental Fillings Necessary?

A dental filling is needed when a tooth develops a cavity due to decay or sustains minor structural damage. If untreated, cavities can lead to:

Types of Dental Fillings

Choosing the right filling material depends on aesthetic preferences, durability, and cost considerations.

1. Composite Fillings (Tooth-Colored)

2. Amalgam Fillings (Silver Fillings)

✅ Composed of silver, mercury, tin, and copper ✅ Extremely durable and long-lasting ✅ Can withstand high chewing forces

📌 Best for: Back teeth that require strength and durability.

3. Ceramic Fillings (Porcelain Fillings)

✅ Made of stain-resistant porcelain ✅ Matches natural tooth color for a seamless appearance ✅ Highly durable and resistant to wear
