In this video Dr. Kopel talks about different types of dental cavity fillings: amalgams vs. composite fillings. He explains when the dental fillings were first introduced and focuses on their advantages and disadvantages.
Inlays and Onlays have been used as indirect fillings and offer a well-fitting, stronger, longer lasting solution to tooth decay. Inlays and Onlays are not likely to discolor over time as tooth-colored resin fillings often do. Inlays and Onlays preserve the maximum amount of healthy tooth structure while restoring decayed or damaged areas, to ensure functional longevity.
Over the years dentistry made many advancements in the conservation of the tooth structure when performing restorations. Maintaining tooth structure increases the prognosis of the tooth if the restoration should fail in the future. If the restoration should fail, a second restoration would not be possible if there is not adequate tooth structure to support it.
Dr. Kopel explains how dentists restore a damaged tooth using inlays and onlays. Today dentists use porcelain instead of gold because porcelain onlays rely only on bond strength.
