Abstract
A dental apparatus for cleaning teeth includes a metallic scaling element formed to receive a slender, rigid, smooth plastic sheath. The scaling element is vibrated by a sonic generator, causing its outer sheath to vibrate as well. The sheath or tip is composed of a material such as polysulfone having good thermal stability for covering the tip of the metallic scaling element. The small diameter free end of the sheath is especially useful in the removal of plaque from an individual's teeth or titanium implants while preventing damage to the surface of the teeth or implants.
