Sometimes the decay or the old restoration in the tooth is large so the tooth may need an inlay or onlay to build back its normal integrity. At Palo Alto Dental Center we are proud to provide a single visit procedure with the CEREC machine (please refer to CEREC information) to restore the tooth. The inlay/onlay is made up of empress which is a special porcelain material which has the same characteristic of the tooth. The inlay/onlay bonds to the tooth so a lot of teeth which years ago would need a crown to regain function would be able to regain its almost original strength with this type of restoration. The new materials enable us to do as conservative preparation as possible.
