The goal of restorative dentistry is to return the teeth to full form (shape) and function. For years, a key tool for achieving this goal has been through the use of metal amalgams (silver looking dental fillings). However, this technique does have some disadvantages. One is the fact that they can involve removal of healthy tooth structure to retain them. Too much “undercutting” can undermine and weaken a tooth resulting in less resistance to biting forces possibly leading to fatigue fractures and cracked tooth syndrome. Another approach is call “biomimetic” which literally means mimicking life. This approach to dentistry is made possible through the structured use of tooth-like materials such as composite resins. Scientific studies and clinical experience have validated their use as both safe and predictable.
By mimicking life, we rely upon our delicate balance of artistry, experience and expertise to provide you with properly restored teeth that function and wear normally, while appearing indistinguishable from natural teeth. Dental composite are now the most commonly used materials for tooth-colored adhesive restorations and have properties similar to a natural tooth’s enamel and dentin. They consist of resin which are plastic and fillers made of silica (a form of glass). The fillers give the composites wear resistance and translucency (see through properties). However, most of the properties of enamel are also mimicked quite well by dental porcelains. Porcelains are a form of ceramic, that are formed by the action of heat. Dental porcelains come in all colors and shades so we can easily and perfectly match the color of virtually any natural tooth. As for longevity, porcelain is typically your best option because it is the closest option in mimicking a natural tooth.
