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.
|Brush Color||Brush Size||Wire Size||Passage Hole Diameter (PHD)|
|Red||2||0.5mm||0.9 mm-1.0 mm|
|Blue||3||0.6mm||1.1 mm-1.2 mm|
|Yellow||4||0.7mm||1.3 mm-1.5 mm|
|Green||5||0.8mm||1.6 mm-1.8 mm|

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.”
