What is the function of glass ionomer material?

Glass ionomer materials play a crucial role in dentistry due to their ability to bond chemically to both tooth structure and restorative materials. One of their significant functions is sealing dentin tubules, which helps to reduce sensitivity and protects the pulp from bacteria or irritants. Furthermore, glass ionomer materials have the unique property of releasing fluoride over time. This release helps to remineralize enamel and dentin, providing an additional therapeutic benefit that contributes to the prevention of caries.

The combination of these characteristics—sealing tubules and fluoride release—makes glass ionomer materials particularly valuable in restorative dentistry and preventive care, especially in areas where moisture control may be challenging.
