Tooth blenching liquid harmless for dental enamel and its using method

Abstract

The invention discloses a tooth bleaching liquid which is harmless to tooth enamel and its application method. The tooth bleaching solution includes a bleaching agent and a thickening agent. Wherein the bleaching agent is a typical peroxide, and the thickener is polyvinylpyrrolidone. The two make up a viscous or viscous tooth bleaching solution. Choose to add alkaline reagents to the bleaching solution, increase light or heat can promote bleaching. Dental trays can be used for bleaching. The bleaching solution is pushed into the tooth tray by a syringe, and the syringe can be a single-chamber, double-chamber or multi-chamber syringe, which contains various components of the bleaching solution. The bleaching solution can be attached to a strip of elastic material and placed on the teeth for bleaching.

Description

technical field [0001] The invention relates to a tooth bleaching solution and a tooth bleaching method. More particularly, the present invention relates to viscous dental bleaching solutions which can be placed in trays or affixed to a patient's teeth to provide brightening, whitening and stain removal benefits without damaging the enamel of the patient's teeth. Background technique [0002] The use of peroxides to whiten teeth with both vital and dead pulp has been known for over 40 years. From the perspective of human beings, human teeth have various shapes and colors. The colors of human teeth are usually white, black, gray, brown and yellow. Environment, nutrition, medical treatment and diet can affect tooth color. Foods such as lingonberries, cranberries, coffee and tea can change a lot from the original color of teeth. Other habits such as chronic smoking or chewing tobacco can darken a person's teeth. Tetracyclines and other medications can have the effect of da...

AI Technical Summary

Problems solved by technology

[0008] However, the physiological problems brought about by accelerating the bleaching process are: first, when the peroxide concentration in the bleaching solution increases, the bleaching solution has a greater stimulating effect on the soft tissue

Second, bleaching solutions are more corrosive to soft tissues as the pH of the solution is increased

Third, when the temperature in the bleaching solution is increased, the bleaching process is more likely to burn soft tissues and even destroy teeth

The problem with putty is that it doesn't flow well around the teeth to properly whiten them

Silica also absorbs the peroxide solution, which affects the properties of the peroxide so that it is not conducive to bleaching

Silica can also have an unfavorable wicking effect on peroxide solutions

[0026] Although CARBOPOL  Very effective in providing a viscous gel in tray bleaching of teeth, but its negative effects on acid etching of enamel and chelation can be devastating for those desiring more beautiful teeth
