Composite restorative materials represent one of the many successes of modern biomaterials research, since they replace biological tissue in both appearance and function. At least half of posterior direct restoration placements now rely on composite materials . Composite resins are a class of dental restorative materials that are a mixture of organic and inorganic components. The primary organic components are the resin, the coupling agent, the initiator and filler. Fillers play a pivotal role in the performance of composite resins. Fillers can be from a wide range of materials. Fillers in composites can be made of glasses, ceramics, metals etc. Glass fillers are usually made of crystalline silica, silicone dioxide, lithium/barium-aluminium glass, and borosilicate glass containing zinc/strontium/lithium. Ceramic fillers are made of zirconia-silica, or zirconium oxide. The development and implementation of composite dental restorative materials rely on a comprehensive understanding of each component of the composite and consideration of methods for changing each component. The aim of the review is to showcase the recent advances in composite resin fillers which have substantially improved the clinical performance of composite
