An in vitro study has shown that conventional glass ionomer cements were less reliable in sealing enamel margins than composite-resin. Often tooth sensitivity wears away within a week or two soon after dental filling. The cement chemically bonds to enamel, dentin and metal structures. Regardless of the advantages of fluoride ion release and uptake by enamel and dentin, coefficients of thermal expansion similar to that of tooth structure, chemical bonding to both enamel and dentin, tooth color replication, and biocompatibility, dentists did not readily adopt materials that were difficult to handle and unreliable in the long term.

One of the disadvantages of glass ionomer cements is their undesirable mechanical properties and bioactivity. Therefore, there are claims against replacing resin-based sealants, the current Gold Standard, with glass ionomer. It is based on the reaction between silicate glass and polyacrylic acid. Croll TP, Helpin ML, Donly KJ. Fluoride ions are not only released by glass ionomers, but are also taken up by associated enamel and dentin, rendering those tooth structures less susceptible to acid challenge by a combination of decreased solubility and disruption of bacterial activity that produces organic acids.4,7,8,19,20-31 Glass-ionomer materials have been shown to be able to release fluoride at a sustained rate for long periods of time (at least 5 years).20 Also, as water-based systems, they act as continuing fluoride ion reservoirs in the mouth by taking in salivary fluoride from dentifrices, mouthwashes, and topical fluoride solutions at the dental office.32 Fluoride ion dynamics is particularly advantageous for those with high susceptibility to dental caries.
