White Composite Fillings
For decades anterior teeth have been filled with natural-looking fillings. These filling materials are called composite fillings. They are colored to match the shade of the tooth being filled so the end result is a tooth that looks natural with no evidence of the filling.
Unlike silver amalgam fillings, composite fillings are a dental treatment that are indistinguishable from the natural tooth structure. Once the cavity area has been cleaned out and prepared, the composite material is mixed and placed in the cavity. Some composites require a curing light. These types of filling materials are laid down in layers and a special light is used on each layer to cure or harden it.
When the area is filled with the composite material, the excess is removed. Next, the filling is trimmed and smoothed with special instruments. After the filling has been adequately smoothed, it is then polished. Now the filling looks and feels like your natural tooth and no one can tell that your tooth ever had a cavity.
What is a Composite Resin?
Acrylic resins and glass or ceramic are the main ingredients for composite resins. There are many different types and each has its advantages for certain applications. Some are best suited for filling smaller cavities while others have the durability and strength to hold up under tons of pressure and therefore can be used as a replacement for amalgam fillings in back teeth. Composite resins have been around for decades and have been improved upon over the years. In their earliest form, these filling materials were not suitable for use on molars or large cavities due to their limited strength. Some current composites have the same strength and durability as silver fillings and hence are used in a variety of circumstances.
