Disclosure is a tooth mineralization solution and a mineralization method thereof. The tooth mineralization solution can be used to mineralize collagen and teeth. The mineralization solution component of the present application comprises two parts, namely, reagent A containing non-collagenous protein analogue and calcium salt, and reagent B is phosphate solution. The mineralization method of the tooth mineralization solution of the present application comprises the steps of first applying the reagent A to the surface of tooth, and then applying the reagent B to achieve tooth mineralization. In addition, the mineralization solution of the present application can also be used to achieve biomimetic mineralization of collagen by the same method, comprising the steps of soaking or floating single-layer reconstituted collagen fibril, collagen gel or collagen sponge in the reagent A, and then soaking or floating in the reagent B to achieve biomimetic mineralization.
