The natural appearance of the tooth structure!
Tooth colored fillings were first introduced to the North American public in the mid 1960's. Since then tooth colored filling materials have undergone continual improvements in durability, esthetics and material handling. The most versatile and widely used tooth colored filling today is composite resin filling. A composite is a material in which filler particles are encased in and bound together by a hard matrix material. For composite resin fillings a fluid matrix of an acrylic, called BIS-GMA, is hardened around glass filler particles to form composite resin.
Tooth colored fillings are dental fillings that restore and mimic the natural appearance of tooth structure. In addition to restoring teeth that have fractured or decayed, tooth colored filings may also be used cosmetically to change the size, color and shape of teeth. This quality is particularly useful in closing gaps between teeth; repairing chipped teeth and making teeth appear to be more straight or even.
