Composite Restorations/Fillings

Dental composite resins are types of synthetic resins that are used in dentistry as restorative material or adhesives. They contain monomers (urethane dimethacrylate) and minerals (glass, quartz, silica, pyrogen). This is a type of plastic that dentists use to fill tooth cavities. It is cured (hardened) with blue light.

BENEFITS OF COMPOSITE RESIN RESTORATIONS

  • Aesthetically closer to the natural appearance of a tooth (material used for the visible surfaces of teeth);
  • Wide range of shades (allows the dentist to seal the decayed tooth and match the initial colour of the restored tooth);
  • Without toxicity (no mercury).

DISADVANTAGES OF COMPOSITE RESINS

  • In some cases Less durable than amalgam;
  • Shrinks during polymerization (curing process with blue light), which can leave a space between the resin and the cavity and lead to marginal tooth decay.
