Dental inlays are restorations that may reasonably be described as fillings created within the dental laboratory. They are typically made of ceramic, gold or porcelain with porcelain often the material of choice due to its strength and potential to match natural tooth colour.
Inlays and onlays are cemented into the tooth and form a very strong bond with the underlying natural tooth surface. They are used for repairing larger cavities or when the tooth structure is significantly broken down. Inlays lie between the cusps of the tooth and are slightly smaller restorations than onlays which tend to be used for substantial reconstructions.
Inlays and onlays will typically be applied during two visits to your dentist. During the first visit the tooth area will be prepared by removing any decay or old filling and an impression made for sending to the dental laboratory. The laboratory will construct the custom made restoration which will be fitted during your second visit to the dentist.
