The present invention relates to a tooth cleaning bristles having a shell surface with a profiling carrying depressions and protrusions with is constructed in the form of a vertical flute, alternating in the peripheral direction and preferably is configured as monofilament. The present invention relates to an electric toothbrush preferably has a toothbrush head such finally toothbrush head having a bristle carrier bristle tooth cleaning such as this one are fixed at least. As can be filled in the same way different requirements essentially required from tooth cleaning bristles, the invention provides a profiling concrete shell surface of the tooth cleaning bristles, and easy embedding into Bristol support by the profiling can be prevented with a tangle of Bristol, which is coupled to tighten, to Bristol bunch if possible, and further, to ensure a powerful cleaning action to the shell surface side. As a result of profiling, length around the tooth cleaning Bristol is the ratio of specific to the cross-sectional area of Bristol. In accordance with the present invention, comprises tooth cleaning bristles shell surface configured to be within the scope of 30mm -1 ~50mm -1 is the ratio of the cross-sectional area of the tooth cleaning bristle length and circumference of the shell surface as a monofilament I held the profiling of the side. Therefore, the shell surface of the tooth cleaning Bristol, is greatly magnified for cylindrical Bristol of the cross-sectional area of the equivalent, therefore, cleaning action to the shell surface side is improved accordingly, toothpaste surface of the shell side can be easily supplied by attaching better to the tooth cleaning bristles. However, despite the profiling of the shell surface side, tooth cleaning Bristol is suitable also for fixing to Bristol corresponding carrier by anchor plugging method.
