Whitening toothpaste can't whiten teeth if you insist on using it. Whitening toothpaste does not lead to tooth whitening. Normal people's teeth are light yellow, which is due to the color of dentin through transparent enamel. Brushing teeth can't whiten teeth, but if the patient's teeth are covered with a lot of pigments or calculus, resulting in unsightly teeth color, the teeth can be removed by ultrasonic supragingival cleaning or sandblasting to restore the original color. However, whitening toothpaste will not whiten teeth, so patients are advised not to go into misunderstanding and not to be misled by advertisements.

And no whitening toothpaste is needed. Any toothpaste will do. Choosing the right toothbrush will not hurt the gums, feel comfortable and have comfortable teeth. Brush your teeth carefully for a while every time, and it won't be long before you find that your teeth turn white. Dental fluorosis caused by excessive fluoride in drinking water will discolor teeth. Some toothpaste containing pearl powder can whiten teeth.

Whitening toothpaste cannot change the color of teeth. Whitening toothpaste can achieve a beautiful "white" effect mainly by increasing friction and adding bleaching ingredients. What whitening toothpaste can do is to remove dental plaque and stain on the surface of teeth and reveal the original color of teeth (light yellow). There are finer and more abrasives in whitening toothpaste, which can grind off the pigment on the surface of teeth, and can really whiten teeth to a certain extent and reduce the exogenous coloring of teeth. But the effect is not lasting. Long-term use of whitening toothpaste will not only change the color of teeth, but also damage the enamel on the surface of teeth, resulting in more sensitive teeth.

Want to whiten teeth, there are two kinds on the market now-white teeth whitening and cold light whitening. White teeth whitening has the characteristics of high efficiency, quickness, strong teeth, comfort and painless. Cold light whitening lasts for a long time, has little damage to teeth, is expensive and has a relatively small application range. Generally speaking, the whitening duration of white teeth is longer than that of cold tube whitening, and the damage to teeth is relatively small.
