Abstract

An interdental brush comprises a brush member (2) having bristle filaments (5) attached to a spine (4) which projects from a handle part (3). The handle part (3) comprises a main body and a resilient transition portion (7). The handle part (3) further comprises a hollow cavity (20), in the transition portion (7). The hollow cavity (20) improves the cushioning effect of the transition portion (7),and increases the length of stroke of the interdental brush by allowing the transition portion (7) to be deformed.
