Dr G Dental Care - Vadapalani provides you the best conservative treatments by our expert dentists. Inlays and onlays are custom-made dental restorations designed to repair teeth that have lost structure due to decay. They are typically employed when a tooth has sustained significant damage that precludes the use of a standard filling, yet does not require a full crown. An inlay is crafted to fit within the grooves and depressions of a tooth, primarily covering the chewing surface between the cusps. In contrast, an onlay extends to cover one or more of the tooth's cusps.
