An Inlay, Onlay or a Crown restoration is needed when teeth are damaged in such a manner that a filling material may not be enough to restore the health and function of a tooth. An inlay, onlay or a crown is an artificial replacement to a damaged or decayed tooth. The procedure for all three is very similar, but the amount of tooth loss dictates which is indictated for each unique situation. These restorations can be made of different types of materials. The choice of material is dependent on several factors: how much masking of the discoloration desired, the strength, the location in the mouth, etc. An all-porcelain crown, the most esthetic type, is used when there is a desire not to show any metal, especially around the gum line of the front teeth. More severe discoloration and misalignment of teeth can be corrected this way.

A bridge on the other hand is an artificial replacement to one or more missing teeth. An artificial tooth is bonded to crowns on the adjacent teeth, holding it permanently in place. Bridges allow the replacement of lost teeth without the use of a dental implant or denture; however they do require the removal of any remaining parts of the damaged tooth (e.g. the tooth roots). Not only do crown's and bridge's restore damaged teeth to look more aesthetically pleasing, they also prevent excess and unnecessary stress on the surrounding, undamaged teeth.
