Comparison of Dental Fillings: GIC vs. Composite Fillings
Composite fillings: When you have cavity or decay in tooth, you need dental fillings. There are two popular options are Glass Ionomer Cement (GIC) and Composite Resin.
These dental materials are used to restore decayed or damaged teeth and improve oral health. Let’s see how these type of fillings compare on various parameters.
What are GIC and Composite Fillings?
Glass Ionomer Cement is a dental material made of glass powder and organic acid. It releases fluoride, which can help prevent further decay. GIC is often used for small to medium-sized restorations and non-load-bearing areas.
Composite fillings are a mixture of plastic (acrylic) and fine glass particles mixed with resin. They are tooth-colored, making them an ideal choice for visible tooth restorations. Composite fillings are versatile and suitable for both front and back teeth, ranging from small to large restorations.
Comparing GIC and Composite Fillings
GIC
- Has a translucent appearance.
- May not perfectly match the natural tooth color.
- Generally less esthetically pleasing.
Composite Resin
- Offers excellent esthetics.
- Can be color and shade matched to surrounding teeth.
- Results in a seamless and natural look.
- Highly popular for visible tooth restorations.
GIC
- Reasonably durable material.
- May not last as long as Composite Resin.
- Less suitable for larger restorations with heavy chewing forces.
- Best for areas with minimal stress.
Composite Resin
- Highly durable and robust.
- Can withstand the pressures of regular chewing.
- Ideal for both front and back teeth.
- Provides longer-lasting restorations.
GIC
- Bonds well to the tooth structure.
- Offers good support to the tooth.
- Potentially reduces the risk of fractures.
- Helps in preserving the tooth’s integrity.
Composite Resin
- Requires minimal removal of healthy tooth structure.
- A conservative choice for restoration.
- Preserves more of the natural tooth.
GIC
- Suitable for small to medium-sized cavities.
