Porcelain inlays and onlays are very aesthetic alternatives to composite fillings. They have a high degree of strength, and as such, are excellent for restoring weakened back teeth such as molars. Inlays and onlays help protect and restore large portions of a decayed or heavily restored tooth, or teeth under a very heavy load.. Unlike crowns, inlays only cover a portion of the tooth, and are therefore more conservative in the amount of tooth preparation required.
These are typically made with porcelain, and are customized to your natural tooth shade, and look very much like your natural tooth. Porcelain inlays and onlays are made from the same strong, tooth colored material that is used for crowns and bridgework. A customized shade makes them very natural in appearance. Unlike tooth-colored composite restorations, inlay/onlays are fabricated using a laboratory process utilizing differing materials, thereby making them stronger and more durable.
