Tooth-colored fillings are composed of a composite, or combination, of porcelain epoxy resin and silica resin fillings. These materials mimic many of the characteristics of natural tooth enamel, including translucency and wear-resistance. Moreover, dental composites help strengthen damaged teeth.
Why need to you Tooth-Colored Fillings
As an alternative to traditional tooth-colored fillings made from mercury or silver, dental amalgam is sometimes used. Because it is white (as is most of the silver in dental amalgam) and nontoxic, it is a popular choice. Unfortunately, there is still a risk of allergic reaction to the mercury that makes up most of the composition. For this reason, many dentists still opt for silver fillings but offer them at a higher cost.
Tooth-Colored Fillings are available in a variety of colors, but most of them are white. Some have been tinted to imitate more opaque fillings, but most are standard shade white. Some are a mixture of several common fillings to enhance the appearance of a less obvious problem area or to hide unattractive features. Resin composites are the most common alternative to porcelain in tooth-colored fillings because of their lower cost and ease of application. Dental composites provide superior strength, durability, and sensitivity to fluoride and silver compared to porcelain.
