Abstract: The present invention relates to an interdental brush (100) for cleaning spaces between adjacent teeth and indicating bristle wear. The interdental brush (100) includes a handle (102), a grip portion (104), an angled neck portion (106), a connecting member (108), a brush head (110), and a plurality of bristles (112). The bristles (112) are configured to remove plaque, food residues, and microbial deposits from interdental spaces. The bristles (112) include an outer coloured layer (114) and an inner coloured core (116). During repeated use, the outer coloured layer (114) wears away due to friction, bending, abrasion, or oral environmental exposure, thereby exposing the inner coloured core (116). The exposure generates a colour-change indication (118) that visually indicates bristle wear and replacement timing of the interdental brush (100). Figure 1 will be the reference.
