What Are Glass Ionomer Fillings?

Glass ionomer fillings 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 glass powder and an organic acid, such as polyacrylic acid, and are known for their ability to bond chemically 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.
  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 of composite resin and glass ionomer materials. They provide better aesthetics than traditional glass ionomers and are used for small to medium-sized cavities.

Glass Ionomer Fillings Uses

Glass ionomer fillings may be recommended by your dentist: 

  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: Glass ionomer fillings are commonly used in pediatric dentistry due to their fluoride-releasing properties and ease of application.
  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, 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.

Patients can expect to spend between $75 to $200 on a single glass ionomer filling. They’re typically less expensive than composite fillings but more expensive than amalgam fillings. Factors that will influence the total cost include the size and location of the cavity, as well as your dental insurance coverage.
