Composite fillings are a mixture of glass or quartz filler in a resin medium that a produces a tooth-colored filling. They are sometimes referred to as composite or filled resins. Composite fillings provide good durability and resistance to fracture in small-to-midsize restorations that need to withstand moderate chewing pressure. Less tooth structure is removed when prepares the tooth, and this may result in a smaller filling than that of an amalgam. Composites can also be "bonded" or adhesively held in a cavity, often allowing to make a more conservative repair to the tooth.
The cost is moderate an depends on the size of the filling and the technique used to place it in the prepared tooth. Composite fillings require a cavity that can be kept clean and dry during filling and they are subject to staining and discoloration over time. Cause less of your natural tooth structure to be removed when being placed. Look Great! Tooth colored fillings help restore strength and function while giving your teeth a healthy and natural appearance.
