Desensitizing toothpaste

Abstract

The invention relates to a desensitizing toothpaste, which comprises, in terms of the total weight of the desensitizing toothpaste, 5%-40% of DP-biomedical glass, 1%-5% of a thickener, 25%-35% of a humectants, and 1%-5% of an interfacial active agent. Specifically, the DP-biomedical glass contains, in terms of the total weight of the DP-biomedical glass, 8.4% sodium oxide, 40.6% of calcium oxide, 39% of silica and 12% of phosphorus pentoxide. By implementation of the invention, tooth sensitivity symptoms can be effectively improved.

Description

technical field [0001] The invention relates to an anti-sensitivity toothpaste, in particular to an anti-sensitivity toothpaste added with DP-biomedical glass. Background technique [0002] Tooth sensitivity is one of the common dental symptoms, and its prevalence is about 8% to 35%. Patients with tooth sensitivity often cannot find immediate and continuous effective treatment, so tooth sensitivity has become an important topic in dental practice. [0003] figure 1 It is a conventional three-dimensional view of a tooth section and an enlarged view of part of its surface. Such as figure 1 As shown, the tooth can be divided into enamel 10 (enamel), dentin 20 (dentin) and pulp chamber 30 (pulp) from outside to inside. Among them, the dentin 20 is mainly composed of HA, and has many dentin tubules 21 connecting the enamel 10 and the pulp cavity 30, and the pulp cavity 30 is filled with nerves 31, blood vessels and lymphatic vessels. [0004] The common cause of tooth sensit...
