If you want
even your fillings to be invisible, composite resins can restore a decayed
tooth or repair a defect. Mostly, composite resins are used on front teeth
that bear less chewing pressure, although composites have been developed
that can be used for selected fillings in back teeth such as molars. Composites are composed mainly of two primary ingredients: a binder of
plastic resin and a filler of finely ground, glass-like particles that give
them a lifelike appearance and durability. Composite fillings can be placed
in one visit, just like a traditional amalgam filling.
An alternative to composite resin for invisible tooth restoration is glass
ionomers composed of fine glass particles. Like composites, glass ionomers
can be used to fill cavities, particularly on exposed root surfaces that are
composed of dentin, which is softer and more sensitive than tooth enamel.
