Is whitening toothpaste really that magical?

Currently, many short video platforms such as Douyin and Kuaishou often post promotional videos from toothpaste sellers.Common false advertising short videos about whitening toothpastes include two types: one about cleaning dentures and the other about peeling quail eggs.Apply whitening toothpaste to your dentures and your dentures will immediately turn white. What is the principle of the video and how does it work?In a denture cleaning video, the chemical properties of iodophor and VA are used to lighten the color of the iodophor solution to deceive consumers by misleading them that their own baking soda and other toothpastes can whiten their teeth.The actual method of surgery is to soak the dentures in iodophor, which will turn the teeth a purple-black color.Soak your toothbrush with toothpaste in the VK solution and then brush your dentures.Chemical changes will occur.The colored iodophor components on dentures will react with VC.Fast decay.This appearance will appear even without toothpaste. Currently, advertising on short video platforms is essentially false propaganda.What is the video principle of bleaching quail eggs and how to make quail eggs white, how does it work?The quail egg bleaching video is essentially a reaction between a weak acid and calcification, which eats away the calcification to deceive consumers.The operation method is to soak quail eggs in an acidic solution such as white vinegar, pick them up in your hands, and then brush the quail eggs with toothpaste. Toothpaste can easily remove stains on the surface of quail eggs.As long as quail eggs are soaked in an acid solution, any toothpaste can perform this function. This type of propaganda is also a method of false propaganda.How does real whitening toothpaste work?There are two main ways to whiten teeth using toothpaste: physical and chemical.The principle of physical whitening involves adding abrasives such as calcium carbonate, sodium bicarbonate and silica to toothpaste to abrade the teeth and make them bright and white.However, this method requires control of the abrasive ingredients in the toothpaste, which is excessive.Friction toothpaste can cause excessive damage to tooth enamel.Thus, toothpaste whitening by friction is a step-by-step process and cannot be achieved overnight.Chemical whitening is a method of adding ingredients like titanium dioxide to toothpaste, which adhere to the surface of the teeth and release active oxygen through the oxides, thereby whitening the teeth to a certain extent.Toothpaste is more effective in cleaning. Whitening is a special cosmetic product and requires a certificate from a third party agency.All toothpastes currently on the market are conventional cosmetic products that have no real whitening effect, and food and drug regulators do not allow toothpastes to promote whitening effects.Therefore, all toothpastes on the market that claim whitening effects are false propaganda.When it comes to custom toothpaste manufacturers, when they produce toothpaste for different groups, they also clearly communicate the true effectiveness of the toothpaste and do not recommend false or excessive advertising.However, there are still unscrupulous traders who will mislead consumers for their own benefit. I hope that more people can properly understand the effectiveness of toothpaste and not be misled.
