Composite resin

Composite resin are a mixture of acrylic resin and finely ground glasslike particles that produce a tooth-colored restoration.
Composite fillings provide good durability and resistance to
fracture in small-to-mid size restorations that need to withstand
moderate chewing pressure. Less tooth structure is removed when the dentist prepares the tooth, and this may result in a
smaller filling than that of an amalgam. Composites can also be
“bonded” or adhesively held in a cavity, often allowing the
dentist to make a more conservative repair to the tooth.
Composite resin can improve the appearance of teeth that
are chipped, broken, cracked, stained, or have spaces between
them.With bonding, tooth-colored materials are applied, or
bonded, to the tooth surface.
