Explorers are used to examine teeth for decay (caries), calculus and other abnormalities. They have thin, flexible tips that taper to a sharp point and come in various single end and double end patterns. All Wise explorer tips are made from spring-tempered stainless steel and are machine ground to exacting tolerances. Each tip is then hand-sharpened and formed into its final shape by expert craftsmen. With Wise, you can be assured of the highest level of quality, consistency, and the sharpest tips in the industry.
