White/Silver Fillings
The most common way of filling a cavity after it has been cleaned out (prepared) is to use a white filling (resin or composite restoration). Dr. Rau uses this technique most frequently. White fillings are very aesthetic but are not as durable as other restorations. Most studies show that they are replaced at a much higher frequency than silver (amalgam) restorations or crowns. Silver fillings (amalgam) are a very stable restoration that lasts longer, but they are less aesthetic. Dr. Rau will use these in posterior teeth (molars) on patients who do not want to replace the fillings regularly or patients who cannot tolerate normal dental clinic settings.
