Porcelain inlays and onlays, also known as indirect fillings, are pre-formed fillings made from tooth-colored material.
Whether you receive an inlay or an onlay depends upon the amount of tooth structure you have lost due to a cavity or trauma. An inlay fits within the grooves of your teeth between its cusps, while an onlay generally replaces the cusps, or highest points, of your teeth as well. Both of these restorations fit snugly within your tooth, where they are bonded in place. Because we use tooth-colored materials, your inlays and onlays look seamless within your smile.
