Dental composite resins (better referred to as "resin-based composites" or simply "filled resins") are dental cements made of synthetic resins.Synthetic resins evolved as restorative materials since they were insoluble, of good tooth-like appearance, insensitive to dehydration, easy to manipulate and reasonably inexpensive. Currently, in most cases, composite materials are used for fillings. The disadvantages of dental composites are many, and though they have been somewhat improved over the last few years, they still leave a lot to be desired. Cast metals also tend to be brittle.

Dental Veneers Pros Cons. The adhesion is dependent upon keeping the entire area perfectly dry, using the proper amount of compound, using the correct curing procedure, and if the entire filling is not cured properly, the composite will remain partially soft. Shrinkage is another common problem with these types of fillings, especially during light curing. Risk of microleakage and secondary caries. a number of disadvantages to the use of amalgam fillings, the most concerning of which . They generally last between 5-10 years and need to be replaced. The most likely reason is that the insurance company doesn’t feel that a back tooth needs to have a white filling and be esthetically pleasing.
