A method for making a dental restoration comprises fabricating a dental workpiece from a pre-sintered dental ceramic material; sintering the dental workpiece defining a sintered dental workpiece; applying a demineralization-inhibiting material inside the pocket or hole of the workpiece; and hardening the demineralization-inhibiting material defining a hardened demineralization-inhibiting portion with an exposed surface exposed in an opening in the sintered dental workpiece. 1. A method for making a dental restoration configured to receive and match a prepared tooth or an implant abutment , the method comprising , in sequence , the steps of:a) receiving a margin line information of the prepared tooth or the implant abutment; followed byb) designing a dental workpiece; followed byc) fabricating the dental workpiece from a pre-sintered dental ceramic material shaped to match the prepared tooth or the implant abutment, and a pocket or hole in an exterior surface thereof; followed byd) sintering the dental workpiece; followed bye) applying a demineralization-inhibiting material inside the pocket or hole of the workpiece; followed byf) hardening the demineralization-inhibiting material while outside a patient's mouth to form a final restoration.2. The method in accordance with claim 1 , wherein the pre-sintered dental ceramic material further comprises at least one of zirconia (ZrO2) claim 1 , alumina (Al2O3) claim 1 , magnesia (MgO) claim 1 , Titania (TiO2) claim 1 , or mixtures thereof.3. The method in accordance with claim 1 , wherein the demineralization-inhibiting material comprises at least one of calcium ions claim 1 , phosphate ions claim 1 , fluoride ions claim 1 , titania ions claim 1 , iodine claim 1 , chlorhexidine claim 1 , glass ionomer claim 1 , resin-modified glass ionomer claim 1 , compomers claim 1 , calcium phosphate claim 1 , tri-calcium phosphate (TCP) claim 1 , tetracalcium phosphate (TTCP) claim 1 , dicalcium phosphate anhydrous (DCPA) claim 1 , ...
