What are teeth whiteners good for?

A mouthful of bright white teeth is the ideal dental condition in many people's minds. The whiteness of teeth not only affects our appearance, but also our dental health. Therefore, many people began to wonder how to whiten their teeth. With the development of science and technology, whitening agents have gradually entered people's lives. So, what principle does whitening agent use to beautify teeth? In other words, what side effects does it have on our bodies?

Most of the whitening toothpastes and tooth strips currently sold on the market contain a certain amount of hydrogen peroxide for teeth bleaching. However, this ingredient is likely to damage the gums and cause chemical burns and other injuries to the oral cavity.

The American Dental Association has warned that the hydrogen peroxide content in teeth whitening products should not exceed 6%. When it reaches 15%-35%, it can easily cause tooth sensitivity and irritate oral soft tissues or gums. This is especially harmful to teeth with poor enamel development, cracked teeth, or moderate wear. Hydrogen peroxide is a chemical substance and should not be used excessively for a long time. It is best not to use it in children and pregnant women. In addition, oxidants will penetrate the surface of the teeth and enter the internal tissues of the teeth. Once the calcium deposition is uneven, the reaction with the oxidants will be uneven, thus bleaching the teeth.

For teeth that turn yellow or dark due to pigment adhesion, you can choose whitening strips, tooth powder, etc. This type of product is mainly used to clean teeth, but you must choose regular brands when purchasing. Many whitening products printed in Japanese or Korean on the Internet have unknown ingredients, so they must be used with caution. The frequency of use should not be too high, no more than 2 times a day, and each time for a maximum of 30 minutes. After use, rinse your mouth and wipe immediately to remove any residual gel on your teeth. People with sensitive teeth should reduce the dosage and should not use it continuously for more than 3 days. If gum burns, throat blisters and ulcers, tooth sensitivity, soft tissue tingling, etc. occur, stop use immediately and go to the hospital for treatment.

The ingredients contained in this type of teeth whitening agent are mainly chemical substances. In this case, the editor recommends that if some of us are sensitive to this chemical, we should try to avoid using teeth whitening agents. At the same time, some of our folk remedies can also effectively whiten teeth, and the effect is very good.
