You don&#8217;t even get a shade guide to measure your progress, which can make it hard to tell if you&#8217;ve come anywhere close to 8 shades of whitening. You use two trays per treatment &#8211; one for the top teeth and one for the bottom &#8211; meaning five treatments in total.<\/p>    <p>Unfortunately, iWhite&#8217;s teeth whitening kits feel quite wasteful, both environmentally and financially. Here&#8217;s why:<\/p>    <ol class=\"wp-block-list\"> <li>It doesn&#8217;t feel great to be throwing away two plastic trays with every treatment.<\/li>    <li>There are no refills available, unlike other styles of kit where you dispense your own gel from a syringe. <\/li>    <li>Five treatments per kit is a lot less than some competitors, which include 10 or more.<\/li> <\/ol>    <p>So although the simple contents might be all you need to get results, they don&#8217;t compare that well to other kits on the market, especially if you want to continue whitening your teeth regularly.<\/p>    <p>To add to this, a number of users report that one or more of the trays had dried up when they came to use it. &#8220;<em>I successfully used this product once and then found that 3 trays were filled with gel that had gone hard!<\/em>&#8221; says one person in their iWhite 2 review, with another complaining &#8220;<em>Arrived today and 3 out of the 5 gels trays are all dried up and crumbling and unable to use such a waste of money<\/em>&#8220;.<\/p>         <div class=\"featured-box featured_box-default\">          <div class=\"featured-box__title\">             Our #1 recommended teeth whitening kit        <\/div>          <div class=\"featured-box__content\">                 <figure class=\"wp-block-image alignright size-full is-resized\">   <img decoding=\"async\" width=\"286\" height=\"300\" src=\"https:\/\/www.dentaly.org\/en\/wp-content\/uploads\/sites\/3\/2024\/08\/snow-wireless-kit-open-286x300-1.png\" alt=\"\" class=\"wp-image-58501\" style=\"width:197px;height:auto\"\/> <\/figure>    <ul class=\"wp-block-list\">   <li>Our #1 Teeth Whitening Kit<\/li>   <li><a href=\"https:\/\/snow.sjv.io\/EK46eD\" target=\"_blank\" rel=\"noreferrer noopener\">Snow<\/a>&nbsp;offers lasting results in just 9 minutes a day and&nbsp;<strong>satisfaction guaranteed<\/strong>&nbsp;or your money back.<\/li>   <li><strong>Fast Results:<\/strong>&nbsp;Noticeably whiter teeth after just one use, with full results in 21 days.<\/li>   <li><strong>Safe for Sensitive Teeth:<\/strong>&nbsp;Designed to be pain-free, even for those with sensitivity.<\/li>   <li><strong>Easy to Use:<\/strong>&nbsp;A convenient and straightforward application process.<\/li>   <li><strong>Celebrity Endorsed:<\/strong>&nbsp;Trusted and used by celebrities for a brighter smile.<\/li> <\/ul>                    <div class=\"featured-box__buttons\">                     <div class=\"mega-button\"><a target=\"_blank\" href=\"https:\/\/snow.sjv.io\/5g62VD\" class=\"orange\" rel=\"\">Get a long-lasting brighter smile with Snow<\/a><\/div>                <\/div>                     <\/div>      <\/div>           <h3 class=\"wp-block-heading\">Ingredients&nbsp;\u2605\u2605\u2605\u2606\u2606 (3\/5 stars)<\/h3>    <p>The main whitening ingredient, Phthalimidoperoxycaproic acid (PAP), is used in several popular whitening kits as an alternative to hydrogen peroxide. <a data-type=\"page\" data-id=\"11098\" href=\"https:\/\/www.dentaly.org\/en\/teeth-whitening-kits\/hismile-reviews\/\" target=\"_blank\" rel=\"noreferrer noopener\">Hismile<\/a> uses this as their main ingredient, but their kits also include remineralizing hydroxyapatite. This is important because there are <a href=\"https:\/\/www.nature.com\/articles\/s41415-019-0011-6\" target=\"_blank\" rel=\"noreferrer noopener\">some indications<\/a> that the PAP formula in iWhite has the potential to soften enamel.

Although it seems the sensitivity claim is true for most people, some do still experience this problem. One reviewer of the Dark Stains kit says it made their teeth &#8220;so sensitive I can&#8217;t bite down on food anymore&#8221;.<\/p>    <p>iWhite&#8217;s teeth whitening kits are labelled as being <strong>made in Belgium<\/strong>. Sylphar manufactures its products internationally and it&#8217;s unclear whether all of the individual components are manufactured in Belgium or whether the kit is just compiled there. iWhite didn&#8217;t reply to our request to clarify this.<\/p>    <p>In any case, iWhite&#8217;s products are ISO certified and conform to the relevant regulations for sale in Europe, which is a good sign of quality and safety.<\/p>   <div class=\"wp-block-image\"> <figure class=\"alignright size-medium\"><img decoding=\"async\" width=\"300\" height=\"200\" src=\"https:\/\/www.dentaly.org\/en\/wp-content\/uploads\/sites\/3\/2019\/08\/how-to-brush-teeth-300x200.jpg\" alt=\"iwhite review how to use\" class=\"wp-image-9042\" srcset=\"https:\/\/www.dentaly.org\/en\/wp-content\/uploads\/sites\/3\/2019\/08\/how-to-brush-teeth-300x200.jpg 300w, https:\/\/www.dentaly.org\/en\/wp-content\/uploads\/sites\/3\/2019\/08\/how-to-brush-teeth-768x513.jpg 768w, https:\/\/www.dentaly.org\/en\/wp-content\/uploads\/sites\/3\/2019\/08\/how-to-brush-teeth.jpg 999w\" sizes=\"(max-width: 300px) 100vw, 300px\" \/><figcaption class=\"wp-element-caption\">Brush your teeth thoroughly before using a whitening kit<\/figcaption><\/figure><\/div>   <h3 class=\"wp-block-heading\">Ease of use&nbsp;\u2605\u2605\u2605\u2605\u2605 (5\/5 stars)<\/h3>    <p>There&#8217;s no doubt that <strong>iWhite&#8217;s teeth whitening kits are easy to use<\/strong>. Their fixed-shape mouth trays don&#8217;t require any moulding, there&#8217;s no LED light to worry about, and the pre-measured gels mean there should be no room for error.<\/p>    <p>You keep the trays in for 20 minutes per treatment, which isn&#8217;t too much of an inconvenience. You won&#8217;t be able to talk much with the trays in, and you might find yourself dribbling a lot &#8211; but the same goes for most other tray-based kits.<\/p>    <p>Note that some people do find the trays quite shallow and difficult to keep in. They are only designed to whiten the front six teeth, which are the most visible.<\/p>    <p>It&#8217;s best to brush your teeth straight before whitening them and avoid eating or drinking for a while afterwards. Using the kit right before bedtime is ideal, or you might want to do it in the morning for an extra burst of brightness during the day. <\/p>    <h3 class=\"wp-block-heading\">Results&nbsp;\u2605\u2605\u2605\u2606\u2606 (3\/5 stars)<\/h3>    <p>iWhite products carry the promise of &#8220;<strong>instant teeth whitening<\/strong>&#8221; and results of up to 8 shades lighter.
