Abstract

A dental cleaning brush, in particular an interdental brush, comprising a plurality of fiber portions retained between two twisted wire sections and extending away from the latter, has at least a certain part of the fiber portions formed such that they extend approximately in the longitudinal direction of the wire sections or the brush core, respectively, in order that painful galvanic effects during the use be avoided.

Claims

1. An interdental brush, comprising a plurality of fiber portions retained between two twisted wire sections and extending away from the latter,

wherein the diameter of the wire sections (1,2) is in the range of 0.1 to 0.25 mm,

wherein each individual fiber portion 96) consists of a plurality of fiber-segment portions (9), the fiber-segment portions (9) extending away from where they are retained between the wire sections (1,2) while fanning out in tufts, and part of the fiber portions (9) also extending approximately in the longitudinal direction of the wire sections (1,2), and

wherein only the fiber-segment portions (9) are glued together where they are retained between the wire sections (1,2) by means of a glue (10) soluble in a solvent that does not attack the fiber-segment portions (9).

2. A dental cleaning brush according to claim 1, wherein the fiber-free end (7) of the wire sections (1,2) is bent over to form a securing eye (8).
