Dental fillings are a common dental procedure used to repair cavities and restore damaged teeth. The procedure involves removing the decayed or damaged portion of the tooth and filling the resulting cavity with a material such as composite resin, amalgam, or gold. In this article, we will explore the different materials used for filling tooth cavities and discuss the benefits and drawbacks of each.
Composite Resin Fillings
Composite resin fillings are a popular choice for fillings because they can be matched to the color of the surrounding teeth, making them less noticeable. They are made of a mixture of plastic and glass materials and are bonded to the tooth using a special adhesive.
Benefits:
- Aesthetically pleasing: Composite resin fillings can be matched to the color of the surrounding teeth, making them less noticeable.
- Bonding process: The bonding process used to attach composite resin fillings to the tooth can help to strengthen the tooth and prevent further decay.
- Versatile: Composite resin fillings can be used to repair a wide range of dental issues, including cavities, chips, and cracks.
Drawbacks:
- Durability: Composite resin fillings are not as durable as other filling materials and may need to be replaced more frequently.
- Cost: Composite resin fillings can be more expensive than other filling materials.
