- Composites, sometimes referred to as filled resins,
provide good durability and
  resistance to fracture in
small to mid size restorations that need to withstand
moderate chewing pressure.
- Less tooth structure is removed when the dentist
prepares the tooth, and this may result in as smaller
filling than that of an amalgam.
- Composites can also be "bonded" or adhesively held
in a cavity, often allowing the dentist to make a more
conservative repair to the tooth.
- Silver-colored (amalgam) fillings are not as natural
looking as one that is tooth-colored, especially when
the restoration is near the front of the mouth, and
shows when the patient laughs or speaks.
- Disadvantages of silver-fillings include possible
short-term sensitivity to hot or cold after the filling
is placed.
