The principle is based on the <strong>teeth whitening <\/strong>practiced in a dental office. The whitening pen employee will place two trays, one on each jaw, which are impregnated with a hydrogen peroxide-based gel. He then attaches a device that allows you to spread your lips, so that you can expose your teeth to a cold blue light for about twenty minutes.<\/p>\n\n\n\n<p>Once the time is up, you remove the trays, rinse your mouth and you're done.<\/p>\n\n\n\n<h2><span class=\"ez-toc-section\" id=\"What_is_the_danger_of_whitening_pens\"><\/span>What is the danger of whitening pens?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>whitening pens use a product that was previously reserved for dentists: hydrogen peroxide. The dosage of this product is strictly regulated by law, and rightly so, because any abuse can damage the teeth, sometimes irreversibly.<\/p>\n\n\n\n<h3>The European regulation governing the use of hydrogen peroxide gel<\/h3>\n\n\n\n<p>The DGCCRF (General Directorate of Competition, Consumption and Fraud Control) <a href=\"https:\/\/www.economie.gouv.fr\/dgccrf\/blanchiment-des-dents-reglementation-protectrice-des-consommateurs#_ftn1\" target=\"_blank\" rel=\"noopener noreferrer\">ensures compliance with the regulation<\/a> that must be applied to teeth whitening products, as they fall into the category of cosmetic products defined by European Regulation No. 1223\/2009 of November 30, 2009.<\/p>\n\n\n\n<p>This regulation defines the dosage of bleaching gels. They are still available over the counter up to 0.1% hydrogen peroxide. Beyond that, these products are reserved for the exclusive professional use of dentists.<\/p>\n\n\n\n<h3>Products used by whitening pens<\/h3>\n\n\n\n<p>whitening pens that comply with the law must therefore remain <strong>below 0.<\/strong>1%. If so, there is no risk to your teeth.<\/p>\n\n\n\n<p>If abused, too much <strong>hydrogen peroxide<\/strong> can affect your teeth and mucous membranes. The gel contained in the mouthpiece always comes into contact with the gums. If the gel is overdosed, you risk at worst a certain irritation which will certainly be unpleasant, but which will not be of any consequence. Your gums will soothe in a few hours.<\/p>\n\n\n\n<p>On the other hand, your <a href=\"https:\/\/nutrident.fr\/en\/?page_id=17847\">enamel<\/a> may be more or less damaged. Too high a concentration can weaken it and create exacerbated sensitivity in your teeth, as they will be less protected. There is also the risk of damaging your amalgams and composites.<\/p>\n\n\n\n<p>If you overdo the sessions and your gel is overdosed, you risk irreparably damaging the enamel of your teeth.<\/p>\n\n\n\n<h2><span class=\"ez-toc-section\" id=\"How_do_I_know_if_a_whitening_pen_is_legal\"><\/span>How do I know if a whitening pen is legal?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>Unless you are a chemist, you have no way of controlling the hydrogen peroxide <strong>dosage of the gel<\/strong>. You need to be able to trust the staff at the bar you choose.<\/p>\n\n\n\n<h3>Customer testimonials<\/h3>\n\n\n\n<p>Choose a whitening pen that observes reliable testimonials. Judge by the welcome you receive. A professional will begin by asking you questions to verify that there are no contraindications: are you undergoing a particular treatment, do you suffer from a chronic dental disease, especially periodontal disease, are you pregnant, are you of age, etc.<\/p>\n\n\n\n<h3>Hydrogen peroxide dosage<\/h3>\n\n\n\n<p>Still, ask about the <strong>dosage of hydrogen peroxide<\/strong>, even if you have no way of checking. If the employee tells you about sodium perborate, you should know that this substance releases hydrogen peroxide on contact with saliva, which is the same thing.<\/p>\n\n\n\n<h3>Prices and hygiene<\/h3>\n\n\n\n<p>Also check the rate. The prices are free, you will pay <strong>between 30 and 300 \u20ac<\/strong>. This big difference is often only justified by the location of the bar, not by the difference in service.<\/p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"alignright size-full\"><img width=\"300\" height=\"200\" src=\"https:\/\/nutrident.fr\/wp-content\/uploads\/2022\/07\/Depositphotos_45966669_s-2015-300x200-1.jpg\" alt=\"\" class=\"wp-image-14042\" srcset=\"https:\/\/nutrident.fr\/wp-content\/uploads\/2022\/07\/Depositphotos_45966669_s-2015-300x200-1.jpg 300w, https:\/\/nutrident.fr\/wp-content\/uploads\/2022\/07\/Depositphotos_45966669_s-2015-300x200-1-254x169.jpg 254w\" sizes=\"(max-width: 300px) 100vw, 300px\" \/><figcaption>The dosage of hydrogen peroxide complies with French standards<\/figcaption><\/figure><\/div>\n\n\n<p>Pay attention to <strong>hygiene<\/strong>.

These places promise to whiten teeth in 20 minutes, while observing strict hygiene rules. But behind the dream image of a cheap whitening method, many doubts remain.<\/p>\n\n\n\n<p>Before trying this method, it is important to be well informed about it. Regularly denounced by health professionals, dentists warn of the dangers of these quick whitening solutions.<\/p>\n\n\n\n<h2><span class=\"ez-toc-section\" id=\"FAQ\"><\/span>FAQ<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<h3>Which professional can perform a teeth whitening?<\/h3>\n\n\n\n<p>Tooth whitening is not a medical procedure, but a comfort procedure for aesthetic purposes. Beauticians can offer whitening solutions. However, only dentists are authorized to apply products in the mouth to whiten teeth.<\/p>\n\n\n\n<h3>What is American teeth whitening?<\/h3>\n\n\n\n<p>American teeth whitening is distinguished by the use of a gel with a higher dose of hydrogen peroxide. This allows for a brighter whitening by going from 2 to 9 whitening shades.<\/p>\n\n\n\n<h3>What people cannot benefit from teeth whitening?<\/h3>\n\n\n\n<p>Tooth whitening is not recommended for certain specific profiles such as pregnant people, people with hypersensitive teeth or with lesions on their teeth<\/p>\n<div class=\"article-data before-content\"><div class=\"article-data__date\"><div class=\"article-data__date-modified\"><time class=\"published\" datetime=\"2022-11-01T10:28:03+00:00\">This article was originally published on&nbsp;<span class=\"2\">November 1, 2022<\/span>&nbsp;and was most recently updated on&nbsp;<span>November 1, 2022<\/span><\/time><br><\/div><\/div><\/div><div class=\"user-info\"><\/div><!--copyscapeskip--><div class=\"medical_references\"><div class=\"medical_references__heading\"><span>Medical Sources<\/span><\/div><div class=\"medical_references__list\"><p><strong>Paris Dental Surgeons Union: <\/strong>Smile <strong>Bars <\/strong><strong><br \/>\n<em><br \/>\n&lt;<br \/>\n<\/em><br \/>\n<\/strong><a href=\"https:\/\/www.scdp.fr\/archives\/bars-%C3%A0-sourire\/\">https:\/\/www.scdp.fr\/archives\/bars-C3A0-sourire\/<\/a><strong><em>&gt;<\/em><\/strong><\/p>\n<\/div><\/div><!--\/copyscapeskip-->","protected":false},"excerpt":{"rendered":"<p>Updated:&nbsp;November 1, 2022 Do you know the whitening pens?
