Abstract
The present invention relates to a cationic material for tooth desensitization, a preparation method therefor, and an application thereof, for use in solving the technical problems in the prior art of long time consumption and limited treatment effect of materials for dentin hypersensitivity. The cationic material comprises a main chain skeleton polymer and a cationic group derived on the main chain skeleton polymer, and the main chain skeleton polymer is connected to the cationic group by means of a covalent bond. The present invention can be used for preparing a drug for treating the dentin hypersensitivity.
