Think of a dental crown as a cap for your tooth. A crown covers your tooth, restoring its shape, size, and appearance. A crown may be necessary to strengthen a decaying or cracked tooth, restore a broken tooth, support a tooth with a large filling, or make a cosmetic change. Additionally, crowns are the last step of a root canal.
A dental veneer is a thin, custom-made shell that covers the front surface of your tooth. Veneers are largely used for cosmetic reasons, such as improving the look of discolored, misaligned, or irregularly shaped teeth. Veneers can also help restore teeth that are chipped or broken.
If your tooth is too damaged to support dental filling, but not quite damaged enough for a crown, a dental onlay might be the answer. A dental onlay, sometimes also referred to as a partial crown, covers one or more cusps of the entire biting surface of your tooth.
