You may not normally think about the mechanics of your mouth, but it is worth noting that your bite can produce a great deal of pressure. Not as much as a Great White Shark, but you still put a great deal of force into your bite. But not all teeth receive the same amount of pressure when you bite or chew. That’s why different teeth need different fillings, depending on how much force they need to withstand. Back teeth, which get a great deal of pressure usually need fillings made from gold or a metal amalgam. Composite, or tooth-colored fillings are not as strong as other fillings, but they do work well for smaller cavities on teeth that do not receive much pressure when you bite or chew. And they are often reserved for fillings that are easily visible to other people.
After removing the decayed tooth material, the dentist will clean and dry the tooth. Then he will mix the composite, which is a combination of an acrylic resin and powdered glass, so that it will blend in with the surface of your tooth. The composite will be applied in layers, and each layer needs to be cured before the next one can be applied. This layering technique is why composite fillings are not as strong as other types; and it is also why it takes longer to place a composite filling.
The new filling will be practically unnoticeable to others, and it will be resistant to stains. But, the filling can be stained with dark colored foods and beverages and the use of tobacco. If your filling becomes stained, your dentist will have to restore the color.
