An interdental brush, also called an interproximal brush or a proxy brush, is a small brush, typically disposable, either supplied with a reusable angled plastic handle or an integral handle, used for cleaning between teeth and between the wire of dental braces and the teeth. Brushes are available in a range of widths, color-coded as per ISO 16409. Interdental brushes are classified according to ISO standard 16409:2006. The ISO brush sizes range from 1 to 7. The ISO brush size is determined by the PHD or Passage Hole Diameter in mm. This PHD is the minimum diameter of a hole that the interdental brush will pass through without deforming the brush wire stem.

Famous quotes containing the word brush:
“A brush had left a crooked stroke
Of what was either cloud or smoke
From north to south across the blue;
A piercing little star was through.”
—Robert Frost (1874–1963)
