In the same way that no skin is totally monochromatic,white teeth don’t existand, like that one,its color is hereditary, revealing itself in different shades of yellow, brown and gray. As we get older, the pulp in the center of each tooth, which is what gives it its brilliance, recedes towards the root. In doing so, the dentin surrounding the pulp is replaced by another, less transparent than the original, which lies under the outer layer of enamel.
Also excessive cleaning with stiff bristle brushes and abrasive toothpaste wears down the enamel and causes the appearance of yellow patches. Similarly,excessive ingestion of fluorideDuring the formation of the teeth, it significantly impairs the preservation of their natural shine. This anomaly, known asfluorosis, can be corrected by applying some whitening toothpastes.
It is also very common for white dots and stripes to appear, as a consequence of some type of problem that arises in the development phase of the teeth. The first teeth are formed during pregnancy and permanent teeth appear in the first four years of life. In both, the calcium and phosphorus crystals carried by the blood make up 70% of the dentin and 95% of the enamel. The abundance or lack of these crystals is another cause that favors the variation in the color of the teeth.
However, the most common stains come from ingestion of coffee, tea, some drugs and antibiotics, and tobacco use. To eliminate these stains and return the teeth to their natural color (even if it is not completely white), dental brands have various whitening products. This is the case of Oral-B Pro-Expert Whitening toothpaste whose composition includes stabilized stannous fluoride that helps restore the natural color of the teeth.
