Posts for tag: tooth colored fillings
It used to be that when it came to treating tooth decay (cavities), your primary option was to have the tooth decay removed and filled with a metal amalgam (silver-colored filling). This treatment sometimes requires a special shape cut called an “undercut” to be drilled into the tooth to hold it in. Unfortunately, it can also involve removal of some healthy tooth structure. Silver amalgam fillings still have limited applications and are still used in back teeth where they don't show in the smile. This is because they are strong and resist biting well; however, over time they can fatigue and fracture.
Older restorative concepts were based upon the development of strong and stiff materials such as gold, which tends to be unyielding and therefore contributed to failures of the remaining tooth substance around restorations (e.g., decay or cracking). Newer concepts tend to get away from the “stronger and stiffer is better” concept and have moved towards safety principles using materials that involve mimicking the properties of natural tooth structure. In fact, it is now clearly established that a new “biomimetic approach” (“bio” – life; “mimetic” – mimicking) to dentistry is possible through the use of tooth-like materials such as composite resins and porcelains. And unlike metal alloys, these newer materials bond directly to the remaining enamel and dentin of which the teeth themselves are made, which both stabilize and strengthen teeth.
These techniques are also suitable for children's teeth and can incorporate fluoride to reduce further decay. But perhaps best of all, using these materials and more modern technologies can restore proper tooth function and normal wear while producing results that appear indistinguishable from natural teeth.

While the goal of restorative dentistry is to return all of the destroyed or lost dental tissues of the teeth to full form (shape) and function, when you blend this goal with the artistry of cosmetic dentistry, the results can be dazzling. Today's modern techniques and materials enable replacement of missing tooth structure that allows bonding directly to the tooth so that it not only is an exact color match but also actually strengthens the tooth. And tooth-colored fillings are not just for front teeth. They can dramatically improve the appearance of all teeth — even your back molars — so that it appears you've never had tooth decay at all!
All of this is accomplished through the use of either tooth-colored dental porcelain or composite resins. Porcelains are a form of ceramic material formed by the action of heat. They are available in many colors and shades made from a powder corresponding to the primary color of the natural tooth structure that is mixed with water and placed into an oven for firing (hence their ceramic nature). When built up in layers by highly trained dental ceramicists, they can be made to mimic the exact natural translucency, staining and contours of tooth enamel.
Dental composite resins are the most common materials used for tooth-colored adhesive restorations today and have properties similar to tooth structure. They consist of resin or special plastics and fillers that are made of silica, a form of glass. The fillers give the composites wear resistance and translucency (see through properties).
It is important to note that besides providing the appearance of beautiful teeth, properly restored teeth function and wear better. But most important to you, they appear indistinguishable from natural teeth! Furthermore, scientific studies and clinical experience have validated their use as both safe and predictable. In fact, these techniques are also suitable for children's teeth and can incorporate fluoride to reduce decay. Together, all of these changes have so significantly impacted the way modern dentistry is practiced that many believe we may have entered into the so-called “post-amalgam (silver metal-colored dental fillings) era.”
