Problems solved by technology

But now commercially available household bleaching agents all have a common shortcoming, that is, the medicine is squeezed into the tooth tray for the patient to wear overnight
Wearing a dental tray for a long time is not only uncomfortable, but also has a lot of inconvenience
Furthermore, saliva can dilute the bleach, and the peroxide reductase in saliva will reduce the activity of the bleach

Embodiment 1

[0018] Bleach: 3% carbomer and 2% polyvinylpyrrolidone, 20% carbamide peroxide solution formulated as a gel.

[0019] Activator: 0.6% sodium fluoride, 3% potassium nitrate, 1% sodium carbonate, 3% sodium silicate, 0.1% sodium lauryl sulfate, 5% ammonia, 0.1% essence, 15% glycerin, add deionized water to 100 %.

Embodiment 2

[0021] Bleach: 3.5% carbomer, 2% PEG-400, 20% carbamide peroxide solution formulated as a gel.

[0022] Activators: 0.6% Sodium Monofluorophosphate, 1% Titanium Dioxide, 3% Sodium Silicate, 0.3% Potassium Citrate, 10% Glycerin, 10% Sorbitol, 0.1% Tween-80, 4% Triethanolamine, 2% Poleol Loxamer, add deionized water to 100%.

Embodiment 3

[0024] Bleach: 3% carbomer, 2.5% methylcellulose in 20% carbamide peroxide solution formulated as a gel.

[0025] Activator: 0.6% sodium fluoride, 1% platinum dioxide, 3% sodium silicate, 0.3% aloe vera gel, 20% glycerin, 0.1% Tween-80, 4% triethanolamine, add deionized water to 100%.

[0026] The tooth bleaching gels of the above-mentioned embodiments are all translucent gels, the pH is weakly alkaline, and they do not flow and have no peculiar smell. The glue produced in Example 1 has high viscosity, good activation function (abundant air bubbles generated), and less sensitivity to patients. The viscosity of the gel made in embodiment two is slightly worse, and there is no obvious difference between the other and embodiment one. Embodiment two patients are more sensitive, and others have no significant difference with embodiment one.

[0027] The above-mentioned bleaching glue has no morphological influence on the animal heart, liver, spleen, lung, stomach, esophagus, oral...

Abstract

The invention relates to a domestic tooth whitener, which overcomes the defects that a domestic tooth whitener has long wearing time, more sensitivity and undefined effect when the domestic tooth whitener is used for treating tetracycline pigmentation teeth, dental fluorosis, and pigment teeth of smoke, lecanorine and the like. The product is a whitening system using urea peroxide as a main component which is added with an activator, a desensitizer and a thickening agent for strengthening the viscosity. Therefore, the product greatly reduces the sensitivity of a patient and the wearing time of a denture base, and reduces the opportunity for reducing the activity of the whitener which is diluted by slobber. Thus, the whitener achieves the exact whitening effect.

Description

technical field [0001] The invention relates to a tooth bleaching system containing a whitening agent and an activator, which can shorten the bleaching time and enhance the effect of the tooth bleaching agent. Background technique [0002] Teeth bleaching dates back to 1877, when oxalic acid was used to bleach teeth. Harwan used hydrogen peroxide as a bleaching agent in 1884, Garreston used chlorine to bleach pulpless teeth in 1895, Walter Kaine used 18% HCI in 1916, and Abbot used 35% HCI in 1918. 2 o 2 As a bleaching agent, and use light heat to enhance the bleaching effect. Since the 1930s, hydrogen peroxide has been used to bleach vital pulp teeth. In the 1960s, when people used a preservative containing carbamide peroxide on oral soft tissue, it was found that carbamide peroxide could have a bleaching effect on teeth. This discovery provided the inspiration and basis for Haywood and Heymann's first use of carbamide peroxide placed in dental trays for home bleaching....
