Originally developed in 1969 the Blotting Brush is generally smaller and has textured bristles that are thinner than those used in conventional brushes. The bristles are designed to go under the gumline and between the teeth to draw in plaque and particles of food using a capillary-like action in the bristles that draws plaque and debris from gum crevices. Complete with a retaining cover to protect and reform the bristles, it is recommended that each brush is only used for 2-3 weeks to maintain its performance.
