The location of the damage or crack and the actual size of the damage or crack are both important in the decision when to recommend repair.

In the acute area, repair is recommended if the damage can be completely covered by a 25 cent US coin (.95 inch diameter circle (24.13 mm.), if the finished pit will be less than 3/16 of an inch (4.76 mm.) and there will be minimal cosmetic blemishes remaining in the damaged area after the repair is completed.
