The manufacturers of toothpaste bleaching promise to the white and shiny teeth. An effective advertising, albeit approximate and misleading, which broadens the market.
Having white teeth and shiny is a desirable goal that pushes many to the purchase of these toothpastes for oral hygiene daily. But as so often the truth is another. With the use of toothpastes “bleaching” is evocative of abrasive effective spots on the enamel surface but with no effect on the improvement of intrinsic tooth color, which can get worse. With prolonged use of whitening toothpaste dental enamel is consumed to abrasion and tooth lose the natural translucent ezza that derives from its proper thickness. Super ficializzandosi the dentin color becomes opaque and yellowish.
Who brush your teeth regularly has no stains surface of the enamel to be eliminated, should not apply the intense action produced by abrasive toothpastes bleach, let alone for long periods of time. We dentists, on the basis of precise scientific evidence, recommend the use of toothpastes with a low index of abrasiveness.
So when you purchase toothpaste should be assessed on its index of abrasiveness. The acronym that represents the RDA, which stands for Relative Dentin Abrasivity. Above 100 this value is too high, and over time can cause damage to the enamel. A low abrasive used to polish the hard surfaces of the tooth without damaging it. Make smooth and glossy surface of the enamel prevents the formation of stains and the retention of bacterial plaque. The manufacturers of toothpaste should allow the consumer to check the index of abrasiveness, indicating on the package. But only some people do.
Who has the need for cosmetic reasons, to whiten their teeth, should know that to act on their natural color or colors internal prodottesi over time, be applied to specific substances based carbammide peroxide or hydrogen peroxide. Professional techniques we use in our studies allow the transferring of such controlled substances on teeth and in a predictable change their color, making them actually more white and bright, without any danger of damage.
