Embodiment 1

[0058] Prepare individually wrapped whiteners and catalytic treatments in tooth whitening gels according to the following recipe:

[0059] Among them, the whitening agent contains 60 parts of hydrogen peroxide, 10 parts of nitrogen-doped titanium dioxide, 150 parts of disodium edetate, 250 parts of glycerin, 5 parts of carbomer, 15 parts of sodium carboxymethylcellulose, 510 parts of parts purified water.

[0060] Its preparation method is as follows:

[0061] Step 1) fully dissolving peroxide and nitrogen-doped titanium dioxide in purified water to obtain a solution;

[0062] Step 2) Slowly add the stabilizer, humectant and binder into the solution, stir evenly, and let stand for 1-2 minutes to obtain the whitening agent.

[0063] The catalyst care agent contains 15 parts of carbomer, 20 parts of sodium carboxymethylcellulose, 330 parts of glycerin, 30 parts of disodium edetate, 10 parts of menthol, 75 parts of sodium fluoride, 10 parts of sodium benzoate, 40 parts of sodi...

Abstract

The invention provides a tooth whitening gel and a preparation method and a use method thereof. The problems are solved that a higher concentration of peroxide is used in order to achieve a better effect and a laser with a longer wavelength makes teeth uncomfortable or damaged in an existing tooth whitening method. The method adopts the low-concentration (3%-10%) peroxide as a main component of awhitening agent, and utilizes the catalysis of non-metal ion doped titanium dioxide with a large visible red shift, under the illumination of a blue laser source of 450+ / -10 nanometre or a purple laser source of 405+ / -5 nanometre, the peroxide is rapidly decomposed by photochemical catalysis, and the low-concentration peroxide can generate enough free radicals to achieve whitening of teeth.

Description

technical field [0001] The invention relates to the technical field of oral care, in particular to a tooth whitening gel, a preparation method and a use method thereof. Background technique [0002] The commonly used clinical method of tooth whitening is to apply substances containing peroxides on the surface of teeth, and then use the heat generated by strong light to catalyze the peroxides, so that the peroxides are decomposed under the thermal effect, generating free radicals, and then whitening teeth. However, there are many disadvantages in this method: 1) Dental clinics generally use high-concentration (20%-40%) peroxide to achieve better whitening effect, and repeated application will cause tooth discomfort to strengthen, causing people to have a series of problems. Oral problems, such as tooth sensitivity symptoms, damage to the mechanical hardness of the enamel surface, and periodontal tissue discomfort; 2) The light source used in conjunction (for example, a laser ...
