Q: What kind of materials are "fillings" made of these days?
A: The main materials are as follows: 1) gold 2) porcelain 3) composite 4) amalgam. These materials are listed from best to worst based on function and longevity. Despite the yellow-gold color, gold has long been the standard to which all other dental restorations are compared. If yellow-gold restorations aren't something you're interested in, bonded porcelain or composite (tooth-colored resin fillings) can be an excellent choice. Amalgam has been with the dental profession for many years and has been a stellar performer in many ways. Amalgams are generally inexpensive and can last decades in some people's mouths. Unfortunately, amalgams are well known for aiding in the fracture of teeth - which can create even more problems for the patient.
