Each of these restorations can come in a variety of materials including metal, porcelain and metal, and ceramic. Traditionally, these restorations are fabricated in a lab and returned to the dentist for final cementation. Inlays may replace an existing large filling and sit inside of the tooth. Onlays are similar to crowns in that the fit around the outside of a portion of the tooth, though they will not cover the entirety of the tooth. Crowns will cover the majority of the tooth and are typically necessary when very large fillings are present or in cases where a tooth has undergone root canal therapy. Bridges replace a missing tooth by crowning the teeth next to the empty space and creating an artificial tooth or teeth between the two crowns. In many cases, bridges are an alternative to partials and implants.
