Abstract
A safety interdental brush is provided that prevents detachment of the brush wire during use, thereby protecting the user. The brush comprises a handle and a brush head fixed to one end of the handle. The brush head includes a wire core and multiple bristles evenly distributed on the outer surface of the wire core. The wire core is composed of at least one stainless steel wire and at least one non-metallic filament, helically wound together. Even if the stainless steel wire breaks due to fatigue, the filament remains intact and continues to connect the broken segments, preventing detachment of the brush head from the handle and ensuring user safety.
