Advances in modern dental materials and techniques increasingly offer new ways to create more pleasing, natural-looking smiles.
Researchers are continuing their decades-long work developing aesthetic materials, such as ceramic and plastic compounds that mimic the appearance of natural teeth.
As a result, dentists and patients today have several choices when it comes to selecting materials used to repair missing, worn, damaged or decayed teeth.
Composite resins, or white fillings, are more expensive. While aesthetically appealing, they require a longer time to place and are not as durable as silver amalgam.
Composite resins are tooth-colored, plastic materials (made of glass and resin) that are used both as fillings and to repair defects in the teeth. Because they are tooth-colored, it is difficult to distinguish them from natural teeth. Composites are often used on the front teeth where a natural appearance is important. They can be used on the back teeth as well depending on the location and extent of the tooth decay.
