Gold is one of the most proven and respected restorative materials available. It has stood the test of time, and every other reparative material may only be compared to it.
Gold is a noble (non-reactive) material that has a very similar coefficient of thermal expansion and contraction to a natural tooth. That makes it a biocompatible and long-lasting. It is also a malleable substance, which allows it to be finished down on the tooth to a seamless transition from gold to the natural tooth structure.Gold is forgiving to the opposing biting surface so it doesn’t cause abnormal wear. These properties, as well as the fact that it can be cast or condensed into any shape, make it a conservative and strong restorative material that will last decades.
The two types of gold most commonly used are cast 18 karat gold for the biting surfaces, and 24 karat gold foil used for non-biting faces or very small fillings on the bite plane. Cast gold requires at least two appointments because the casting must be fabricated in a laboratory and then cemented, finished, and polished at the second appointment. Gold foil restorations can be completed in a single visit since the foil is condensed directly into the prepared cavity and then finished and polished.
A common misconception patients and even some dentists have with gold is that it is not aesthetic. However, since gold restorations can be made conservatively, preserving more of the natural tooth structure, most gold restorations will go unnoticed to observers. Dr. Johnson is always cognitive of his patients’ cosmetic desires and uses gold sparingly to ensure that aesthetics are maintained.
Despite all the benefits gold has to offer, it is a technique-sensitive material; especially important to maximize the longevity of the restoration. Dr. Johnson has extensive training in the use of gold and continues to expand his knowledge by participating in a Gold Study Club on a monthly basis. You are a work of art.
