Whitening dental pasta: Do they really work?

The market offers a huge variety of Dentifriquesfrom those who promise to whiten the teeth to which they ensure greater care of gums or dental plate. But to what extent do they meet what they announce?

In the case of whiten pasteswhich usually present themselves as the fast path towards a whiter smile, the reality is that Its effect is limited. This is remembered by the periodoncist Olalla Argibaymember of the Spanish Periodontics Society (SEPA), who explains that European regulations restrict the amount of hydrogen peroxide – the most effective whitish agent – to 0.1 %, “a low concentration that As soon as it produces a real bleaching effect“The goal is simply to eliminate some superficial spots.

Given this panorama, specialists insist that the basis of good oral health remains the use of fluorinea brushing technique adequate and the periodic reviews With the dentist.

Specific pasta

Beyond the bleachers, the market also offers dentifrices for specific problems: sensitivity, gums that bleed, halitosis either Tartination control. According to Argibay, these products are useful when there is a particular symptom, although he clarifies that “They are not essential If your general oral health is good. “In his words,” a adequate interdental hygienea correct brushing techniqueand a paste with fluorine appropriate are usually enough. “

The SEPA spokeswoman adds, however, that when these special pastes are used properly they can provide benefits and complement the daily hygiene routine. Of course, he emphasizes that “they do not replace periodic visits to the dentist.” And warns: “He Professional control It allows to determine if, in addition to a specific dentifric, some Clinical treatment. A early diagnosis and preventionn are key to avoiding future problems. “

Ingredients and efficiency

On their composition, the formulas are adjusted based on the need to which they are addressed. For example, sensitivity pastes usually contain more potassium or arginine nitrate, while bleaching incorporates soft abrasives and low peroxide doses. Those that fight bad breath include zinc or cetilpyridinium chlorideand antisarro, compounds such as pyrophosphates or zinc citrate, always within regulated and safe levels.

And what ingredients should it prioritize in any toothpaste? Argibay stands out as essential: the fluorinefundamental for Prevent caries and strengthen enameland soft abrasives such as silicathat help Eliminate plaque and spots.

In addition, it mentions the role of light detergents that facilitate foam formationtogether with moisturizers and thickeners that They improve texture. “Some dentifric pastes incorporate moisturizers and thickeners to maintain the texture, along with flakes and non -cariogenic sweeteners – as mint or xylitol – for Improve flavor and breath. These basic components guarantee cleaning, protection, and a fresh sensation in the mouth, “explains the specialist.

The key role of fluoride

Among all ingredients, fluoride occupies a central place. This mineral, says the periodoncist, Strengthens enamelfavors the Remineralization of weakened areas and Bacteria proliferation brakes that produce acids responsible for caries.

The recommendation for adults is clear: a daily use of pasta with concentrations of between 1,000 and 1,500 ppm. In the case of older children, this component offers triple protection: chemistry, by reinforcing the enamel; mechanics, by enhancing brushing action; and microbiological, limiting the activity of harmful bacteria.
