Tooth colored fillings
In the past, teeth were filled with a mixture—or amalgam—of different metals. Today that is changing as more natural-looking and metal-free fillings are becoming the preferred approach.
What is a tooth color filling (White Filling)?
A composite filling is a tooth-colored FDA approved resin used to restore decayed teeth. Composites are also used for cosmetic improvements of the smile by changing the color of the teeth or reshaping disfigured teeth.
How is a composite placed?
Following preparation, the dentist places the composite in layers; typically using a light specialized to harden each layer. When the process is finished, the dentist will shape the composite to fit the tooth. The dentist then polishes the composite to prevent staining and early wear.
What are the advantages of composites?
Aesthetics are the main advantage of composites, since dentists can blend shades to create a color nearly identical to that of the actual tooth. Composites bond to the tooth to support the remaining tooth structure, which helps to prevent breakage and insulate the tooth from excessive temperature changes.
What are the disadvantages?
After receiving a composite, a patient may experience some postoperative sensitivity. Composites tend to wear out sooner than silver fillings in larger cavities, although they hold up as well in small cavities.
