The main active ingredients in teeth whitening strips are hydrogen peroxide or carbamide peroxide. Hydrogen peroxide can decompose in the presence of metals, light, and heat to produce free radicals. These free radicals break the unsaturated double bonds (color molecule locks) in the organic components of stained teeth and combine with them. Through oxidative decomposition, they form low-molecular-weight colorless substances that further react to produce carbon dioxide and water. Therefore, the main principle of teeth whitening strips is the breakdown of pigmented substances through oxidation generated by free radicals.
According to dentists, reputable brands of teeth whitening strips contain low concentrations of peroxide, generally below 10%. When used correctly, they can ensure the safety of teeth and gums while achieving whitening effects, which has been proven in numerous experiments. However, it takes at least two weeks or more of consistent use to see noticeable results.
During the whitening period, the action of peroxide on the tooth surface makes the teeth more susceptible to staining from food and beverages. It is recommended to consume white or colorless foods and drinks such as water, milk, chicken, and fish. It is advised to avoid tea, red wine, soy sauce, and certain brightly colored fruits.
As for whitening products of uncertain origin, some may increase the concentration of peroxide in pursuit of faster results, which can potentially damage the teeth. It is not recommended to choose such products.
