A filling is used to restore the function, integrity and morphology of missing tooth structure with metal or composite resin materials.

Dr. Tran does two types of fillings, silver amalgam and composite resin.

Amalgam is widely used for fillings, mainly for posterior teeth. Amalgam leaches tiny amounts of mercury and while some concerns have been raised, there is currently no evidence that any of this mercury remains in the body nor that dangerous levels are ever reached.

Composites are tooth colored. A dental composite typically consists of a resin-based matrix, such as a bisphenol A-glycidyl methacrylate (BISMA) resin like urethane dimethacrylate (UDMA), and an inorganic filler such as silicon dioxide silica. Compositions vary widely, with proprietary mixes of resins forming the matrix, as well as engineered filler glasses and glass ceramics. The filler gives the composite wear resistance and translucency. A coupling agent such as silane is used to enhance the bond between these two components. After tooth preparation, a thin bonding agent layer is applied. The tooth is then filled and the composite is light cured. At the end, the surface will be shaped and polished.
