A dental restoration or dental filling is a treatment to restore the function, integrity, and morphology of missing tooth structure resulting from caries or external trauma.  It is also done so that the caries/decay doesn’t progress further in to the tooth.

Glass Ionomer
Glass Ionomeris ideal for the pre-cooperative or uncooperative child as well as the “high caries risk” child. Glass ionomers have many advantages as a restorative material. These include, but are not limited to: the ability to bond chemically to dentin and enamel, biocompatibility, favorable thermal expansion, decreased moisture sensitivity and the ability to act as a fluoride release and then as a reservoir. 

Composite (white) Fillings
Composite (white) Fillings Tooth-colored fillings are the most life like material used to fill cavities. Composite fillings can be done in one visit. Once the decay is removed, the tooth is filled with this composite material that hardens immediately after placement. Composite resin offers a strong and esthetic alternative. However it is technique sensitive, and a highly moisture sensitive material. In ideal clinical situations, composite resin restorations may well be the material of choice.
