Inlays and Onlays are stronger than white fillings and last longer. They also preserve tooth structure unlike a crown, so its like a partial crown.
These partial crowns are utilized when there is still a healthy enamel portion of the tooth. An inlay or onlay is a like a puzzle piece that will be fitted into the remaining portion of the tooth to help increase its strength. This piece is usually crafted out of porcelain or gold, but can also be made of a composite material. We will make the determination as to which restoration will work best in your specific situation.
An inlay is used when there is not damage to any of the cusps of your tooth and is essentially place within these cusps. An onlay is used when there is slightly more extensive damage to the tooth structure. This type of restoration is placed over at least one of the cusps on the tooth.
