NES-1692

Supragingival calculus has a way of clinging stubbornly to enamel just above the gumline, and that’s precisely where the NES-1692 Towner U15 sickle scaler does its best work. The blade carries two straight cutting edges that meet at a sharp point, built to fracture and lift hardened deposits off the tooth surface in short, controlled strokes rather than dragging or burnishing them smooth.
Unlike curved area-specific curettes, the Towner pattern keeps a straight, triangular cross-section from heel to tip, which gives it more rigidity when working against dense, well-bonded calculus. That stiffness matters most on anterior teeth and the facial and lingual surfaces of posterior teeth, where visibility is good and the operator can angle the blade precisely against the deposit without needing to feel around blind.
A few practical notes worth mentioning: the pointed tip lets it double as a quick tactile diagnostic instrument for checking margins after scaling, confirming the surface feels smooth rather than assuming it based on sight alone. The shank is forged from surgical stainless steel in one continuous piece, so there’s no weak joint prone to loosening after repeated sterilization.
It sharpens cleanly and holds an edge through normal clinical use, though like any sickle scaler it performs best with routine maintenance rather than being pushed past the point of dullness. A solid choice for hygienists doing supragingival debridement and routine prophylaxis appointments.
