White fillings are actually a composite of either quartz or glass filler and resin, a mixture that produces teeth-colored filling. This combination is commonly known as dental composite resin or, more simply, filled resin. Resin-based composites are known for their excellent durability, resistance against fractures when it comes to small-to-midsize restorations and moderate chewing pressure. Dental composite resin also requires significantly lesser amounts of natural tooth structure removed which results in smaller, less-obvious filling in comparison with that of amalgam.
Another advantage of dental composites is that they can be adhesively held together, thereby allowing the dentist to perform more constructive repair work. The cost of the service depends on the scale of the filling and the technique employed by the dentist. One must keep in mind that the procedure usually lasts longer than the insertion of amalgam.
The installation of dental composites requires a completely clean and dry cavity. The composites are also prone to stains and discoloration as the time goes on.
