Area-specific allows for deep scaling, root planing and periodontal debridement. Offset blade provides a perfect working angulation for the tooth surface. Offset blade angulation means only the lower cutting edge of each blade is used. Long-angle for molar buccal and lingual surefaes and a more pronounced angle than 7/8 for less accessible root surfaces. EverEdge™ 2.0 scalers are the sharpest and longest-lasting scalers on the market. Using a superior heat treatment process, enhanced finishing process and an optimized steel, EverEdge™2.0’s edges are scientifically measured to be over 72% sharper than the next closest competitor.
