Abstract: A slender polishing tip is disclosed. In one example, it is an interproximal polishing bur, which is a dental instrument that is a small bit used in a high-speed handpiece by a dentist to perform dental work on the teeth of a patient. It smooths the adjacent tooth or restoration. An adjacent tooth may inadvertently become nicked by the high-speed handpiece while working on a tooth, leaving the adjacent surface roughened. This roughened surface will attract more bacteria and can be harmful to the health of the dentition. Presently, there are no such burs slender enough to fit into the small space available between the prepared tooth and the adjacent tooth to allow appropriate smoothing. The interproximal polishing bur described is small and slender with a particular shape designed to re-finish and re-polish the surfaces of an adjacent gold crown, porcelain crown, and natural dentition.
