Abstract
Novel, improved filaments for brushes. The filaments include a colored region provided by a dye colorant and the colored region is adapted to provide a color intensity which can change in response to increased use of the filament to provide a signal indicative of filament wear. The filaments are particularly useful in toothbrushes.
