Composite resins are among the cosmetic options of materials available for the restoration of back teeth such as molars and premolars. They are mainly composed of a polymer (plastic) and very hard and very small inert particles. Composite resins have long been used for front teeth. They are used to correct defects caused by cavities, breaks, incorrect tooth position, etc. Having improved over the years, dentists now use them to fix defects of the back teeth.


Composite resins are suitable for replacing broken or lost replacements in premolars and molars and to fix small to medium-sized defects (i.e.: cavities, breaks, developmental defects, etc.).. They consequently possess a strong resistance to fractures and wear, and can last several years. These materials are also available as fluids and are used as sealants to prevent the development of cavities in pits and fissures on the top of teeth at the back of the mouth


  • Composite resins blend in extremely well with natural teeth color since they are available in many shades. The final results are consequently very aesthetic.
  • The preparations for teeth before the application of composite resin are generally more “conservative” than for amalgams.
  • The final replacements adhere to the tooth. Before the application of successive layers of composite resin, the dentist applies a composite resin sealant on the tooth. The composite resin adheres to the tooth, strengthening it further


Composite resin restorations require more steps than amalgam restorations, they can therefore be more difficult to do.Composite.They are more expensive than amalgam restorations and when composite resins are used in large-scale preparations, they are less durable than amalgams.
