What is the Objective of Porcelain Inlays and Onlays?
The objective of porcelain inlays and onlays is to address issues that a traditional filling cannot. For example, fillings are typically used for smaller or even medium-sized cavities. However, if your cavity is deeper or wider but does not need a crown, porcelain inlays and onlays can help restore your tooth while offering a natural look and feel. In addition, porcelain inlays and onlays can be used to help teeth or replace fillings that are compromised, weak, cracked, or damaged.
How is an Inlay Different from an Onlay?
A porcelain inlay is smaller than an onlay, and the main difference is its placement. For example, porcelain inlays are used when the middle part of the tooth is affected, and onlays are beneficial if one or more cusps have been impacted. Although onlays are larger than inlays, they still do not cover as much of the tooth’s surface as a crown. Typically, a crown covers the entire surface. Thus, porcelain inlays and onlays are a great option when a filling is too small but a crown is too large.
