Toothbrush head with set of bristles

An interdental twisted wire brush having roughened, tapered and rounded bristle ends prepared by rotating the interdental brush both transversely to the axis of the brush and axially along its longitudinal axis, while flexing the bristles and grinding the bristle ends of the interdental brush against a flat, moving abrasive surface.

Interdental brushes having roughened, tapered and rounded bristle ends

An interdental handle having a molded-in-place twisted wire brush that includes a handle having a generally tapered first portion of reduced cross-section at one end with a flexing and substantially resilient capability, and a second portion of a larger cross-section at an opposite end which is relatively rigid. A brush with a twisted wire stem includes a distal end embedded in at least the first portion of the handle and a proximal end projecting from the first portion of the handle. At least one concentric groove is adjacent the distal end of the twisted wire stem for preventing protrusion of the twisted wire stem from the first portion during the manufacturing process. The concentric groove includes a diameter which is substantially larger than the diameter of the twisted wire stem.
