Composite has better life and strength than GIC filling. Gic releases fluoride but composite does not.

Hello Lybrate user, by your question im guessing you are a dentist. I prefer resin modified GIC for restoration of cervical abrasion. Masticatory forces cause cuspal flexure and the stresses are concentrated in the cervical lesion, tending to dislodge restorative materials in this region. Resin-modified glass ionomers are about twice as flexible as glass ionomers and are therefore more likely to be retained during flexing of the tooth. In addition, they absorb water for several days after photostabilization and the resulting expansion tends to offset the shrinkage caused by the initial set of the resin components. If resin composite alone is used to restore cervical lesions, poor marginal adaptation at the gingival margin is inevitable. This is mainly caused by polymerization shrinkage away from the gingival surface due to poor adhesion at the dentin surface.

Composite is better. But your dentist will decide what to use.
