High cleaning efficiency: Ordinary toothbrushes usually have only one bristle surface, while a three-sided soft-bristled toothbrush has three bristle sides and is able to clean multiple sides of the tooth at the same time. When brushing, a single action can cover more tooth surfaces, which can remove food debris and plaque from teeth more quickly and comprehensively than traditional toothbrushes, effectively improving cleaning efficiency and saving brushing time.
