What Are Glass Ionomer Fillings?

Glass ionomer fillings, also known as glass ionomer cement, are a type of dental restorative material used to repair decayed teeth, fill cavities, and replace old fillings. They’re made from a unique combination of glass powder and an organic acid, such as polyacrylic acid. One of their key advantages is their ability to form a chemical bond with the tooth structure, ensuring a secure and long-lasting restoration.

Types of Glass Ionomer Fillings

There are several types of glass ionomer fillings available, each with its own unique properties and applications: 

  1. Conventional Glass Ionomer: Conventional glass ionomer fillings are self-cured and have been used for many years in dentistry. They’re suitable for various applications, including small to medium-sized cavities.
  2. Resin-Modified Glass Ionomer: Resin-modified glass ionomer fillings combine the benefits of traditional glass ionomers with resin-based materials, offering improved strength and aesthetics. They’re often preferred for restorations in visible areas.
  3. Compomer (Composite-Glass Ionomer Hybrid): Compomers are a hybrid material that combines the benefits of composite resins and glass ionomers. They provide better aesthetics than traditional glass ionomers and are suitable for small to medium-sized cavities.

Glass Ionomer Fillings: Uses and Applications

Glass ionomer fillings are versatile and can be recommended by your dentist for various dental applications, including: 

  1. Small to Medium-Sized Cavities: Glass ionomer fillings are particularly suitable for repairing small to medium-sized cavities in both adult and pediatric patients.
  2. Root Surface Cavities: They can be used on root surfaces to treat cavities caused by gum recession or root exposure.
  3. Pediatric Dentistry: Due to their fluoride-releasing properties and ease of application, glass ionomer fillings are commonly used in pediatric dentistry, particularly for baby teeth.
  4. Non-Stress-Bearing Areas: They’re ideal for non-stress-bearing areas of the mouth, such as the front teeth and some premolars.

Advantages and Disadvantages of Glass Ionomer Fillings


Glass ionomer fillings offer numerous benefits that make them a desirable choice for dental restorations:

  • Natural appearance and translucency
  • Fluoride release aids in cavity prevention
  • Minimal tooth preparation is required
  • Suitable for non-stress-bearing areas
  • Biocompatible and well-tolerated by tissues


While glass ionomer fillings offer many advantages, it’s essential to be aware of their limitations:

  • Limited durability compared to some alternatives
  • Sensitive to moisture during placement
  • Weaker than materials like amalgam
  • Aesthetic limitations in highly visible areas

The Glass Ionomer Filling Procedure

The glass ionomer filling procedure begins with a thorough dental examination and diagnosis, followed by tooth preparation and dental sedation to ensure comfort. The decayed portions of the tooth are removed, and the glass ionomer material is mixed and applied to fill the cavity, with optional light curing to enhance durability. 

After shaping and polishing the filling for a natural appearance, patients are advised on oral hygiene and dietary precautions. Regular follow-up appointments may be scheduled to maintain the filling’s integrity. Glass ionomer fillings are favored for their fluoride-releasing properties and suitability for certain dental applications.


The cost of glass ionomer fillings typically falls between $75 and $200 per filling. While they are generally less expensive than composite fillings, they may be more costly than traditional amalgam fillings. Factors such as the size and location of the cavity, as well as your dental insurance coverage, will influence the total cost.
