What Are Glass Ionomer Fillings?

Glass ionomer fillings, also known as glass ionomer cements, are a type of dental restorative material commonly used to repair decayed teeth, fill cavities, and even replace old fillings. They’re made from a combination of minute glass particles and an organic acid, such as polyacrylic acid, and are known for their ability to chemically bond to tooth structure.

Types of Glass Ionomer Fillings

There are various types of glass ionomer fillings, including:

  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 in baby teeth and permanent teeth.
  2. Resin-Modified Glass Ionomer: Resin-modified glass ionomer fillings combine the benefits of traditional glass ionomers with resin-based materials, offering improved strength, aesthetics, and a smooth and natural finish. They’re often preferred for restorations in visible areas like the front teeth.
  3. Compomer (Composite-Glass Ionomer Hybrid): Compomers are a hybrid of composite resin and glass ionomer materials. They provide better aesthetics than traditional glass ionomers and are used for small to medium-sized cavities in both baby teeth and permanent teeth.

Glass Ionomer Fillings Uses

Your dentist may recommend glass ionomer fillings for:

  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 tooth roots and tooth necks to treat cavities caused by gum recession or root exposure.
  3. Pediatric Dentistry: Glass ionomer fillings are commonly used in pediatric dentistry due to their fluoride-releasing properties, ease of application, and suitability 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.

The Glass Ionomer Filling Procedure

The glass ionomer filling procedure begins with a thorough dental examination and diagnosis by our experienced dental team. Here’s what you can expect:

  1. Tooth Preparation: Your dentist will carefully remove any decayed portions of the tooth, creating a clean cavity space for the filling material.
  2. Dental Sedation (if needed): For your comfort, dental sedation options may be provided, ensuring a stress-free experience.
  3. Mixing and Applying the Filling: The glass ionomer material is mixed and carefully applied to the prepared cavity space, using specialized dental lights or curing methods as needed.
  4. Shaping and Polishing: The filling will be shaped and polished to achieve a smooth and natural finish, blending seamlessly with your tooth.
  5. Post-Procedure Instructions: Our dental team will provide guidance on proper care for your new filling, including oral hygiene recommendations and dietary precautions if necessary.

Regular dental check-ups and good oral hygiene habits are essential for maintaining the integrity and longevity of your glass ionomer fillings.


Patients can expect to spend between $75 to $200 on a single glass ionomer filling. They’re typically less expensive than composite resin fillings but more expensive than amalgam fillings. The total cost can vary based on factors such as the size and location of the cavity, the type of glass ionomer material used, and your dental insurance coverage.
