1, pigmentation. Long-term smoking, long-term drinking of strong tea or coffee, Coca-Cola, beverages or tobacco pigments will adhere to the teeth, and the teeth will inevitably turn yellow after a long time.
2, dental fluorosis. If fluoride ions enter the enamel during tooth development, resulting in enamel hypoplasia and unhealthy tooth development, it is easy to cause tooth yellowing, tooth decay and other dental problems.
3. Improper daily cleaning. Many people regard brushing their teeth as a trivial matter, but this trivial matter can affect the health and beauty of teeth. When the bacteria on the tooth surface gather to a certain amount, it will not only make the teeth yellow, but also cause serious tooth problems such as dental caries, periodontitis and gingivitis.
Scientific solution to tooth yellowing;
1, tooth cleaning:
When it comes to tooth whitening, the first thing many friends think of is tooth cleaning.
Indeed, tooth washing can clean the surface of teeth and help them restore their original luster and color, but it can't whiten teeth.
In fact, cleaning your teeth is to let a professional dentist clean your teeth thoroughly.
2, cold light whitening:
Although it is called "cold light" whitening, it mainly relies on bleach to whiten teeth. The bleaching agent used is generally hydrogen peroxide, which is also a strong oxidant.
The whitening effect varies from person to person. Want pearl white, may have to deal with many times.
3, porcelain teeth/beauty crown:
Porcelain teeth have a great whitening effect. It is necessary to grind off some of the original teeth and replace them with artificial materials. This method is as white as you want.
4, tooth veneer/porcelain veneer:
Its principle is to grind the teeth a little thinner, and then cover the teeth with artificial materials to improve the color and shape of the teeth.
For tetracycline teeth, dental fluorosis, enamel dysplasia and other problems that cannot be solved by bleaching, tooth veneering is a better solution.
