An interdental or interproximal ("proxy") brush is a small brush, typically disposable, either supplied with a reusable angled plastic handle or an integral handle, used for cleaning between [[Human tooth|teeth]] and between the wires of [[dental brace]]s and the teeth.

The use of interdental brushes in conjunction with tooth brushing has been shown to reduce both the amount of plaque and the incidence of gingivitis when compared to tooth brushing alone.<ref name=":0">{{Cite journal|last=Poklepovic T, Worthington HV, Johnson TM, Sambunjak D, Imai P, Clarkson JE, Tugwell P|date=2013|title=Interdental brushing for the prevention and control of periodontal diseases and dental caries in adults|journal=Cochrane Database of Systematic Reviews|pmid=24353078|doi=10.1002/14651858.CD009857.pub2|issue=12|page=CD009857|doi-access=free}}</ref> Although there is some evidence that after tooth brushing with a conventional tooth brush, interdental brushes remove more plaque than [[dental floss]],<ref name="pmid22726785">{{cite journal|title=As an Adjunct to Tooth Brushing, Interdental Brushes (IDBs) are More Effective in Removing Plaque as Compared with Brushing Alone or the Combination Use of Tooth Brushing and Dental Floss|year=2012|last1=Gluch|first1=Joan I.|journal=Journal of Evidence Based Dental Practice|volume=12|issue=2|pages=81–83|doi=10.1016/j.jebdp.2012.03.016|pmid=22726785 |issn=1532-3382}}</ref> a systematic review reported insufficient evidence to determine such an association.<ref name=":0" />

The size of interdental brushes is standardized in [[ISO]] 16409.<ref name="ISO 16409:2010">ISO 16409:2006 + Amd.1:2010, ''Dentistry&nbsp;– Oral hygiene products&nbsp;– Manual interdental brushes''</ref><ref name="ISO 16409:2014">ISO/[[Draft International Standard|DIS]] 16409:2014, ''Dentistry&nbsp;– Oral hygiene products&nbsp;– Manual interdental brushes'' (draft standard)</ref> The brush size,<ref>Different versions of the standard specify different brush sizes.</ref> which is a number between 0 (small space between teeth) and 8 (large space), indicates the ''passage hole diameter''. This corresponds to the space between two teeth that is just sufficient for the brush to go through without bending the wire. The color of the brushes differs between producers. The same is the case with respect to the wire diameter.<ref>Neither the brush color nor the wire diameter are specified in ISO 16409:2010 or ISO/DIS 16409:2014. Just some general properties of the wire (e.g., should not bend) or specifications of the packaging (e.g., the brush size must be noted) can be found there.</ref>
