Maintaining good dental health is crucial for overall well-being, and dental fillings play a vital role in this. Whether it’s due to cavities, cracks, or decay, fillings help restore the function and integrity of damaged teeth. But with various options available, understanding the pros and cons of different types of dental fillings can help you make an informed decision. Let’s dive into the details.
What Are Dental Fillings?
These are materials used to fill cavities or repair cracked and broken teeth. They help restore the tooth’s shape and function while preventing further decay. Common reasons for needing a filling include tooth decay, fractures, or wear and tear.
Different Types of Dental Fillings
There are several types of dental fillings, each made from different materials and offering unique benefits. The choice of filling depends on factors such as the location of the tooth, the extent of the repair needed, and personal preferences.
Amalgam Fillings
Amalgam, also known as silver fillings, are made from a mixture of metals including silver, mercury, tin, and copper. They have a distinctive silver colour and have been used in dentistry for over 150 years. Their long history of use is a testament to their reliability and effectiveness.
Pros of Amalgam
- Durability: It lasts up to 15 years or more.
- Strength: Withstands significant chewing forces.
- Cost-effective: Generally less expensive than other options.
Cons of Amalgam
- Aesthetics: Noticeable silver colour.
- Mercury Content: Contains mercury, which some patients prefer to avoid.
- Potential Allergies: Rare allergic reactions to the metals.
Composite Fillings
These are made from a mixture of plastic and fine glass particles. They can be closely matched to the colour of your natural teeth, providing a seamless restoration. The material is moldable, allowing dentists to shape it to fit the cavity precisely before hardening it with a special light.
Pros of Composite
- Aesthetics: Blends well with natural teeth.
- Bonding: Bonds directly to the tooth, providing support.
- Versatility: Suitable for repairing chipped, broken, or worn teeth.
Cons of Composite
- Durability: Lasts about 5-10 years, less durable than amalgam.
- Cost: More expensive than amalgam.
- Procedure Time: It takes longer to place.
Ceramic Fillings
These are made from porcelain and are known for their natural appearance and durability. They are often used for inlays, onlays, and crowns, providing a high-quality restoration that mimics the natural tooth enamel.
Pros of Ceramic
- Aesthetics: Excellent color matching and stain resistance.
- Durability: Can last 15 years or longer.
- Biocompatibility: Less likely to cause adverse reactions.
Cons of Ceramic
- Cost: One of the most expensive options.
- Brittleness: This can be more brittle and may require more substantial tooth removal.
Gold Fillings
These are made from a gold alloy, providing a striking appearance and excellent durability. They are custom-made in a dental laboratory and then cemented into place, offering a unique and luxurious restoration.
Pros of Gold
- Durability: Can last 20 years or more.
- Strength: Withstands significant chewing forces.
- Biocompatibility: Generally well-tolerated by the body.
Cons of Gold
- Cost: The most expensive option.

Glass Ionomer Fillings
These are made from a mixture of glass and acrylic. They are typically used for fillings below the gum line and in children, offering a practical solution for specific dental needs.
Pros of Glass Ionomer
- Fluoride Release: Releases fluoride, helping protect the tooth.
- Biocompatibility: Generally compatible with the body.
- Ease of Placement: Can be placed quickly and easily.
Cons of Glass Ionomer
- Durability: Lasts about 5 years, less durable than other options.
- Strength: Not as strong, unsuitable for large cavities.
Resin Ionomer Fillings
Resin ionomers are similar to glass ionomer fillings but include additional resins to improve strength. They combine the benefits of glass ionomer materials with enhanced durability and aesthetic qualities.
Pros of Resin Ionomer
- Fluoride Release: Provides added protection.
- Aesthetics: Better colour matching than glass ionomer.
- Bonding: Provides good bonding to the tooth.
Cons of Resin Ionomer
- Durability: Less durable than composite or amalgam.

Here’s a breakdown to help guide your decision:
Tooth Location:
- Visible Teeth: Composite or ceramic options are best due to their natural appearance and colour-matching ability.
- Molars and Premolars: Amalgam or gold options are ideal for teeth that handle significant chewing forces due to their durability.
Cavity Size:
- Small Cavities: Composite works well for small to medium cavities, offering a seamless look.
- Large Cavities: Amalgam and gold are better suited for larger cavities, providing more strength and longevity.
Aesthetic Preferences:
- Natural Appearance: Composite or ceramic options blend in well with natural teeth.
- Unique Look: Gold offers a distinct appearance that some may find attractive despite its visibility.
Durability Needs:
- Long-Term Durability: Gold and amalgam are known for their long-lasting durability, often exceeding 15-20 years.

Cost Considerations:
- Budget-Friendly: Amalgam is generally the least expensive option and offers good durability.
- Willing to Spend More: Gold and ceramic are more expensive but provide excellent longevity and aesthetics.
Sensitivity Concerns:
- Metal Sensitivity: If you’re sensitive to metals, avoid amalgam and gold; opt for composite or ceramic instead.
- Thermal Sensitivity: Composite tends to be less sensitive to temperature changes compared to metal options.
Time Constraints:
- Quick Procedure: Amalgam and composite can usually be completed in a single visit.
- Multiple Visits: Gold typically requires more than one visit due to the need for custom lab work.
Health and Safety Concerns:
- Mercury Concerns: If worried about mercury exposure, consider composite or ceramic instead of amalgam.
- Biocompatibility: Ceramic is highly biocompatible and unlikely to cause adverse reactions.
Personal Habits:
- Grinding or Clenching: If you grind or clench your teeth, choose stronger options like gold or amalgam to withstand the extra pressure.
