Abstract

The invention discloses tooth whitening gel as well as a preparation method and use method thereof. The gel contains the following raw materials in parts by weight: 0.7-0.9 part of carbomer, 18-22 parts of hydrogen peroxide, 0.04-0.06 part of EDTA-2Na, 0.6-0.8 part of triethanolamine, 0.15-0.25 part of potassium nitrate and 12-18 parts of a PBS buffer solution. The preparation method comprises thefollowing steps: fetching carbomer and water, and stirring; and adding hydrogen peroxide, EDTA-2Na, triethanolamine, potassium nitrate and the PBS buffer solution. Peroxy-radical ions in tooth whitening gel are stimulated by virtue of a blue light stimulating instrument so as to release hydrogen peroxide molecules, the hydrogen peroxide molecules generate oxidation-reduction reaction on the surfaces of teeth, and then pigments attached to the teeth are removed, so that the aim of safe and efficient tooth whitening is achieved.

Description

technical field [0001] The invention relates to the technical field of tooth whitening, in particular to a tooth whitening gel and its preparation and application method. Background technique [0002] In today's highly developed material civilization, people want to make themselves more handsome and beautiful, and become like movie stars through plastic surgery or makeup. In addition to paying attention to clothing and skin color, urban men and women gradually turn their attention to their teeth. Through orthodontics or implants, the teeth are arranged neatly, and they are constantly looking for ways to whiten their teeth. The teeth that people envy are completely "armed to the teeth". Baby teeth are milky white in childhood and gradually turn yellow as we age. [0003] There are two main reasons for tooth yellowing and coloring: exogenous and endogenous. A variety of bacteria on the surface of the teeth will secrete a lot of sticky substances, and absorb the pigments in ...
