Tooth Whitening and Tooth Strengthening Method

Abstract

A tooth whitening and tooth strengthening method is disclosed which is harmless to the human body and with which it is possible to remove dental plaques, tartars, coloring components and organic pellicles, promote calcification, repair the surface of teeth by reconstruction of enamel, whiten teeth and prevent caries.

The tooth whitening and tooth strengthening method first applies acid solvents such as citric acid, acetic acid, malic acid, malic acid or ascorbic acid with a pH of 0.5 to 5.0. to the surface of teeth as a first stage of treatment, applies hydroxyapatite which is dissolved in saliva or saliva-like solvent as a second stage, and then applies fluoride as a third stage.

Claims

1. A tooth whitening and strengthening comprising the following three stages of treatment performed in sequences: applying acid solvents to surface of teeth so as to remove coloring components and pellicle from the surface of teeth as a first stage; applying hydroxyapatite which is dissolved in a solvent to the surface of teeth so as to efficiently calcify tooth components on the surface of teeth, restore and strengthen the surface of teeth as a second stage; and applying fluoride to the surface of teeth to improve strength of the surface of teeth by enhancing acid resistance and whiteness of the tooth as a third stage.

2. The tooth whitening and tooth strengthening method according to claim 1, wherein saliva or saliva-like solvent is used as the solvent.

3. The tooth whitening and tooth strengthening method according to claim 1, wherein the acid solvents are pH of 0.5 to 5.0 acid solvents.

4. The tooth whitening and tooth strengthening method according to claim 1, wherein the acid solvents include at least any of citric acid, acetic acid, malic acid, malic acid or ascorbic acid.

[BRIEF DESCRIPTION OF THE DRAWINGS]

[0021] FIG. 1 is photographic images explaining the effect of applying citric acid with a pH2.5 to the surface of teeth;

[0022] FIG. 2 is photographic images explaining the effect of applying hydroxyapatite powder of 4 nm to 1.7 mm dissolved in saliva or saliva-like solvent to the surface of teeth;

[0023] FIG. 3 is photographic images explaining the effect of applying 9,000 ppm sodium fluoride to the surface of teeth.

[MODE FOR CARRYING OUT THE INVENTION]

[0024] Hereinafter, the tooth whitening and tooth strengthening method will be described. However, the present invention is not limited to the embodiments described below.

[0025] In the present invention, as a first stage of treatment for the tooth whitening and tooth strengthening method, plaques, tartars, coloring components and pellicle are removed from the surface of teeth by applying acid solvents such as citric acid, acetic acid, malic acid, malic acid or ascorbic acid with a pH of 0.5 to 5.0. A second stage is to apply hydroxyapatite which is dissolved in saliva or saliva-like solvent to the surface of teeth to efficiently calcify, repair and strengthen surface of teeth. In addition, fluoride is applied as well to improve acid resistance and strength and whiteness of the tooth, as a third stage. These three stages enable to strengthen the enamel on the surface of teeth by crystallization of hydroxyapatite, then to enhance the bonding of the crystal structure by fluorine bonding in enamel, realizing tooth whitening of higher whiteness, restoration of enamel apatite crystal, remineralization and strengthening the tooth structure.

Acid

[0026] The acids used in the tooth whitening and tooth strengthening method in the present invention are not limited to those that are not harmful to the human body when used on the oral mucosa.

[0027] The acids used in the present invention are citric acid, acetic acid, malic acid, malic acid or ascorbic acid with a pH of 0.5 to 5.0.

Hydroxyapatite Particles

[0028] The tooth whitening and tooth strengthening method in the present invention uses a solvent that dissolved hydroxyapatite with an average particle diameter 4 nm to 1.7 mm, which is smaller particle size than usual, in saliva or saliva-like solvent.

Fluoride

[0029] The fluoride used in the tooth whitening and tooth strengthening method in the present invention are fluoride sodium fluoride, calcium fluoride, and monotin fluoride with 500 ppm to 100,000 ppm.

[FIRST EMBODIMENT]

[0030] FIG. 1 explains the embodiment of removing plaques, tartars and pellicle by using citric acid with a pH2.5. FIG. 1(a) shows the surface of teeth before pH2.5 citric acid is applied and FIG. 1(b) shows the surface of teeth 5 minutes later. As shown in FIG. 1, plaques, tartars and pellicle attached to the surface of teeth can be removed by applying pH2.5 citric acid.

[0031] FIG. 2 shows that hydroxyapatite particles of 4 nm to 1.7 mm dissolved in saliva or saliva-like solvent binds to the apatite that makes up the surface of teeth, resulting in restoration of the surface of teeth and apatite reconstruction, when applied to the surface of teeth.

[0032] FIG. 2(a) shows the surface of teeth before application of hydroxyapatite particles and FIG. 2(b) shows the surface of teeth 5 minutes later. It can be seen in the FIG. 2 that it binds to the apatite that makes up the surface of teeth and realizes tooth restoration and apatite reconstruction.

[0033] FIG. 3 shows that sodium fluoride with 500 ppm to 100,000 ppm applied to the surface of teeth strengthens the tooth structure due to shrinkage of the enamel apatite crystals. FIG. 3(a) shows the surface of teeth before application and FIG. 3(b) shows the surface of teeth one minute later. As can be seen in the FIG. 3, sodium fluoride shrinks the apatite crystal : from 8.17 atto (1 mm of 10,000,000,000,000,000) before application to 8.12 atto (after application).

[INDUSTRIAL APPLICABILITY]

[0034] According to the tooth whitening and tooth strengthening method in the present invention, tooth strengthening method which includes cosmetic tooth whitening can be provided. Therefore, the present invention can be used not only for medical applications, but also as a tooth whitening and tooth strengthening method performed for cosmetic purposes in non-medical whitening salons, dental offices and the like.
