How long does a glass ionomer filling last?
Glass ionomers release fluoride, which can help protect the tooth from further decay. However, this material is weaker than composite resin and is more susceptible to wear and prone to fracture. Glass ionomer generally lasts five years or less with costs comparable to composite resin.

Once the cavity has been washed and gently dried, the GIC can be placed, inserting the nozzle to the base of the cavity and filling the preparation from the base upwards to avoid air inclusions.
Is glass ionomer a permanent restoration?
Glass ionomers were used as permanent restoratives that could bond to the tooth and release fluoride. Also, their inherent translucency allowed them to be shaded to match tooth structure.
How do dentists remove dental cement?

How does glass ionomer bond to tooth?
Micromechanical interlocking, caused by glass-ionomers being self-etching due to the polyacid component. True chemical bonding. This involves ionic bonds being formed between the carboxylate groups on the polyacid molecules and calcium ions in the tooth surface [51].
What is dental glass ionomer?
Glass ionomer is essentially a flexible paste, that is used to form a tight seal between the internal tooth (exposed, due to a cavity) and the surrounding environment. It acts as a sealant, allowing the tooth to remain protected.
Does dental cement come off?
