The tobacco, coffee, red wine or other foods can change the color of teeth in the long term. Before performing tooth whitening, many people turn to whitening toothpaste in order to regain a brighter smile. While they cannot change the natural color of the teeth, whitening toothpastes erase the yellowish discoloration of the teeth more effectively than a conventional toothpaste.
Can toothpaste whiten teeth?
The polishing action of whitening toothpaste helps to regain the natural color of the enamel following several days or weeks of regular use, according to the importance of the surface colorations. It also makes it possible to prolong the effect of scaling-polishing in the dental practice. But she will not do better, no toothpaste can lighten the color of the teeth.
What are the precautions for whitening toothpastes?
The more abrasive the toothpaste, the more effective but aggressive it is for the enamel, which exposes to the risk of dental hypersensitivity and cavities. In addition, the wear of the enamel makes visible to the dentine, which, it… is yellow! A clue, the RDA (Relative dentin abrasivity), indicates the degree of abrasiveness of a toothpaste on the dentinbut no regulations require the manufacturer to determine or communicate it.
However, we can find the RDA certain references known on the Internet (*for example the sites swissdocu.ch (in French) or froherzahn.de (in German). In the search engine, type RDA toothpastes and the name of the site). For information, and RDA less than 40 (on a scale of 0 to 250) indicates low abrasivenesset greater than 80 high abrasiveness.
What are the most effective teeth whitening agents?
Of the agents polissants facilitate the detachment of dental plaque and erase stains on the surface of the enamel.
Baking soda
The most common are the flintsthe bicarbonate de soude (sodium) or thethe bottom. These ingredients are present in greater quantities in most whitening toothpastes and/or are found there in a form which increases their action, for example due to the size of the grains.
Charcoal can be abrasive
Coal, used for these same properties. ” But no studies show it to be more effective than other polishing agents “, says Dr. Christophe Lequart, while dental erosions have been reported with this type of toothpaste. “Overall, there is a lack of hindsight on their degree of abrasiveness, which calls for caution”.
colored pigments give the illusion of redder gums and/or whiter teeth. Their strengths? An immediate impression of whiteness… but short-lived!
How to properly use whitening toothpaste?
We respect the terms of employment (daily use or not) and we limit ourselves to two or even three months of useespecially if you have sensitive teeth. In this case, a specific toothpaste is also recommended (Elmex Sensitive Professional Whiteness, Sensodyne Repairs & Protects Whiteness).
in case of gingivitis, you can alternate a whitening toothpaste with your usual toothpaste.
If the whitening toothpaste formulation does not contain fluoride, it is alternated with a fluoridated toothpaste.
Avoid whitening toothpastes in children. Even if some can be used from the age of 6, it is better to avoid whitening toothpastes in children because the enamel of their teeth is more fragile.

Fluorine completes the formula (1,455 ppm).
In what situations? If you are looking for a “healthy” reference with a good polishing action.

In what situations? If you are looking for a reference to charcoal, complete and organic!
The opinion of the pharmacist: It is rare to know the degree of abrasiveness of a toothpaste, especially when it is charcoal! Moderately abrasive, this formula is less powerful than others… but has the merit of making it known. It also provides complete oral protection.
Signal White Now Gold, for an optical effect
Count around €3.40 for a 75ml tube. A toothpaste developed by the Unilever laboratory.
