Navigating Dental Fillings: A Guide to Types and Choices

Dental fillings serve a pivotal role in maintaining oral health, addressing cavities, and restoring damaged teeth. The diverse array of dental filling materials available allows dentists to tailor treatments to meet the unique needs and preferences of each patient. Let’s explore the different types of dental fillings, including traditional and modern options, highlighting their characteristics, advantages, and considerations.

Common Types of Dental Fillings

1. Amalgam Fillings

Amalgam fillings, also known as silver fillings, have been a cornerstone in dentistry for over a century. They consist of a mixture of metals, including silver, tin, copper, and mercury. Amalgam is known for its durability and cost-effectiveness.


  • Durability: Amalgam fillings are highly durable and can withstand the forces of chewing over an extended period.
  • Cost-Effective: Amalgam fillings are generally more affordable compared to some other materials.


  • Aesthetic Concerns: The metallic appearance of amalgam fillings may not be suitable for visible teeth, impacting overall aesthetics.
  • Mercury Content: While considered safe by scientific consensus, some individuals express concerns about the mercury content in amalgam fillings.

2. Composite Resin Fillings

Composite resin fillings are tooth-coloured and consist of a mixture of plastic and fine glass particles. They are widely used for their aesthetic appeal and versatility.


  • Aesthetic Appeal: Composite resin fillings can be matched to the natural colour of the tooth, providing a discreet and natural appearance.
  • Versatility: Suitable for both front and back teeth, composite resin fillings can address various cavity sizes.


  • Durability: While durable, composite resin may not be as robust as amalgam, making it more suitable for smaller to moderately sized cavities.
  • Staining: Composite resin fillings may be prone to staining over time, especially with habits like smoking or frequent consumption of staining foods.

3. Gold Fillings

Gold fillings, although less common in contemporary dentistry, are renowned for their durability and longevity. They are typically composed of gold alloy, which includes a combination of gold, copper, and other metals.


  • Durability: Gold fillings are exceptionally durable and can withstand the forces of chewing for an extended period.
  • Biocompatibility: Gold is biocompatible and well-tolerated by gum tissues, reducing the risk of allergic reactions.


  • Cost: Gold fillings tend to be more expensive than other options due to the cost of the material and the labour-intensive process of fabrication.
  • Aesthetic Preferences: The visible gold colour may not appeal to individuals seeking a more discreet filling option.

4. Porcelain Fillings

Porcelain fillings, also known as ceramic fillings, offer a natural appearance and excellent durability. They are often used for inlays, onlays, and veneers.


  • Aesthetic Appeal: Porcelain fillings can be colour-matched to the natural tooth, providing a realistic and aesthetically pleasing result.
  • Durability: Porcelain is durable and can withstand normal biting forces.


  • Cost: Porcelain fillings are relatively expensive, reflecting the cost of the material and the intricate fabrication process.
  • Fracture Risk: While durable, porcelain may be more prone to fractures than materials like amalgam or gold.

Modern and Specialised Dental Fillings

5. Glass Ionomer Fillings

Glass ionomer fillings are a modern option that releases fluoride, offering additional benefits for tooth health. They are often used for small to mid-sized cavities, especially in areas with less stress during chewing. Types of Dental Fillings


  • Fluoride Release: Glass ionomer fillings release fluoride, contributing to the prevention of further decay.
  • Versatility: Suitable for both front and back teeth, glass ionomer fillings are versatile and bond well to tooth structure.


  • Durability: Glass ionomer fillings may not be as durable as materials like amalgam or gold, making them more suitable for specific applications.
  • Sensitivity: Patients may experience increased sensitivity immediately after the placement of glass ionomer fillings.

6. Composite Ceramic Fillings

Composite ceramic fillings combine the aesthetic benefits of composite resin with the durability of ceramics. They are a popular choice for individuals seeking both natural appearance and strength.


  • Aesthetic Appeal: Composite ceramic fillings mimic the appearance of natural teeth and are available in various shades.
  • Durability: These fillings offer enhanced durability compared to traditional composite resin.


  • Cost: Composite ceramic fillings may be more expensive than traditional composite resin fillings due to the added benefits.

7. Polymer Glass Fillings

Polymer glass fillings, also known as nanocomposite fillings, represent an advanced form of composite resin. They contain nano-sized particles for improved strength and durability.


  • Enhanced Strength: Polymer glass fillings exhibit improved strength and wear resistance compared to traditional composite resin.
  • Aesthetic Benefits: They retain the aesthetic advantages of tooth-coloured fillings.


  • Cost: The enhanced properties of polymer glass fillings may come with a higher cost compared to standard composite resin.

Special Considerations and Emerging Options

8. Tooth-Coloured Amalgam Alternatives

Researchers are exploring tooth-coloured alternatives to traditional amalgam fillings. These materials aim to provide the durability of amalgam while maintaining a more natural appearance.


  • Durability: Similar to traditional amalgam, these alternatives focus on providing robust and long-lasting restorations.
  • Aesthetic Appeal: They offer improved aesthetics compared to silver-coloured amalgam fillings.


  • Availability: Tooth-coloured amalgam alternatives may not be as widely available as traditional amalgam fillings.

9. Bioactive Fillings

Bioactive fillings are designed to interact with the natural tooth structure, releasing minerals like fluoride, calcium, and phosphate. They aim to support tooth health and prevent further decay.


  • Bioactivity: Bioactive fillings contribute to the remineralisation of tooth structure, promoting overall oral health.
  • Versatility: They can be used for various cavity sizes and in different areas of the mouth.


  • Cost: Bioactive fillings may be more expensive than some traditional options due to their advanced features.

Tooth-coloured fillings, such as composite resin and porcelain, are durable but may not withstand the same biting forces as silver amalgam. The choice depends on the location of the tooth and aesthetic preferences.

3. Do gold fillings last longer than other types of dental fillings?

Gold fillings are known for their durability and longevity, often outlasting other filling materials. However, they may not be suitable for individuals seeking a more discreet option.

4. Are there any safety concerns with amalgam fillings containing mercury?

Amalgam fillings with mercury are considered safe by the majority of scientific studies and health organisations. The mercury undergoes a stable chemical reaction within the filling material.

While dental fillings don’t require special care, maintaining good oral hygiene practices, attending regular dental check-ups, and avoiding habits that may contribute to damage are essential for their longevity.

8. Can dental fillings be used for cosmetic purposes, even if there is no cavity?

Yes, dental fillings, particularly tooth-coloured options like composite resin and porcelain, can be used for cosmetic purposes to address issues like chipped or misshapen teeth.

In many cases, old dental fillings can be replaced with newer materials for cosmetic or functional reasons. Consult with our dentist to determine the most appropriate course of action.
