A toothpaste producing method and a product are disclosed, comprising multiple whitening particles with outer surfaces uniformly distributed with multiple nano-bacteriostatic powders to form multiple tooth protection units to be mixed with other ingredients of the toothpaste such as cleansing agent, polishing agent, humectant and binder to form a toothpaste. The whitening particles in the toothpaste have ingredients same as the main composition ingredients of the tooth and have outer surfaces uniformly distributed with multiple nano-bacteriostatic powders, so that during toothbrushing with the toothpaste, the whitening particles of the tooth protection units can be permeated and timely filled to the damaged portion of the tooth and form a protection film to protect the teeth. The multiple nano-bacteriostatic powders can achieve the bacteriostatic effect to protect tooth health and prevent dental caries.一種牙膏之製造方法及成品,係包含有:多數美白顆粒,每一美白顆粒外表面均勻分布多數奈米抑菌粉粒,據以製成多數牙齒保護單元,其後多數牙齒保護單元與牙膏其他成分之清潔劑、研磨劑、保濕劑與結合劑充分混合,使成為一牙膏;該牙膏內之美白顆粒成分與牙齒主要組成成分相同,而該美白顆粒外表面又均勻分布多數奈米抑菌粉粒,所以以此牙膏在刷牙過程中,牙齒保護單元之美白顆粒得以滲入至牙齒受損部位適時填補,並得以形成一保護膜保護牙齒,而多數奈米抑菌粉粒得以達到抑菌效果,以保護牙齒健康及預防蛀牙者。a‧‧‧製備多數美白顆粒b‧‧‧製備多數牙齒保護單元c‧‧‧製作牙膏
