Dental inlays and onlays are restorative techniques similar to crowns, but they require less removal or filing of the original natural tooth structure.
What is the difference between an inlay and an onlay? An inlay fits within the cusps of the teeth and therefore covers less of the natural tooth. On onlay fits within as well as up & over the cusps of the tooth, covering more of the tooth’s surface — for this reason an onlay is also called a “half crown.”
The process generally requires two visits. During the first visit, x-rays may be taken, the tooth will be prepared to receive the inlay or onlay, and an impression of the tooth and adjacent teeth will be made. Once the inlay/onlay has been created by the lab and returned to our office, your second appointment will involve fitting it to your tooth and ensuring that it is a proper fit in your mouth and bite.
