Use these instruments to remove supragingival calculus.

Instructions for Calculus Removal

  1. Put the tip third of the scaler’s cutting edge against the tooth.
  2. Tilt the instrument toward the tooth at a 70–80 degree angle between tooth and blade.
  3. Apply lateral pressure and activate the scaler with vertical, diagonal or horizontal pull strokes. For best control, use 2–3 mm strokes.
