Cmiile

Cmiile is a Danish oral-care company specialising in cosmetic teeth whitening, founded in 2015 and based in Trige, near Aarhus [1]. It sells at-home whitening kits, strips, toothpaste and related dental devices, built around a peroxide-free whitening gel. The company frames its purpose around making cosmetic teeth whitening, once available mainly through dentists, something people can do at home [1].

The brand is active. Its products are stocked across several Danish and Norwegian retailers, and its website serves localised Danish and Norwegian storefronts alongside an English default.

According to the company, Cmiile was founded in 2015 in Denmark "to help people smile more without being ashamed of their smiles" [1]. It describes its mission as putting focus on dental care and teeth whitening, and giving people whiter teeth and what it calls healthy oral hygiene. The stated ambition is for Cmiile to be seen as a dedicated expert in cosmetic teeth whitening and oral care.

A recurring theme in the company's own messaging is accessibility: it says it offers technology that previously only dentists could provide, bringing cosmetic whitening into the home [1]. Alongside this, Cmiile states that sustainability is a priority and that it tries to use as little plastic as possible in its products [1].

Cmiile's catalogue centres on cosmetic teeth whitening but extends across everyday oral care. Its signature items include a Teeth Whitening Kit, sold with an LED light and mouthpiece, plus Teeth Whitening Strips, a Day & Night toothpaste, a Natural Whitening charcoal powder and a water flosser.

The defining feature of the whitening line is that it is peroxide-free. Rather than hydrogen peroxide, the gel uses PAP — phthalimidoperoxycaproic acid — as the active whitening agent, which the company says protects teeth from the pain and sensitivity it associates with peroxide-based products [3]. The formula also includes soothing ingredients such as chamomile extract, aloe vera and potassium nitrate, the last aimed at managing sensitivity [3].

Cmiile says the gel was developed in collaboration with dentists and is clinically proven to whiten teeth, with each treatment taking about ten minutes [3]. On its homepage the company claims results of up to eight shades whiter after six treatments, and offers a money-back guarantee for customers who see no results [2]. It further states that its products are CE certified, FDA approved and compliant with EU legislation [3]; these are the company's own regulatory claims rather than independently verified findings.

Cmiile reaches customers both directly and through third-party retailers. In Denmark it lists stockists including Matas, Douglas, Elgiganten, Beautycos, Nice Hair, med24 and CoolShop [2], and its strips and kits appear on Danish retail sites such as well.dk and nicehair.dk. In Norway the brand is carried by retailers including Beautycos, Vita and Nicebeauty [4]. The company's website operates dedicated Danish and Norwegian sections, reflecting a Nordic, multi-region focus rather than a global one.

Editorial coverage of Cmiile is limited. The brand has been featured in an advertorial in the Norwegian outlet Dagbladet, listed among at-home whitening products [6]. It maintains an active customer-review presence on Trustpilot; some reviewers there and on retailer pages report whitening results less pronounced than the brand's "eight shades" marketing suggests [5]. No major beauty-press awards or independent editorial reviews were identified.

Cmiile remains in operation as of 2026. Its products continue to be stocked across multiple Danish and Norwegian beauty and electronics retailers, and its localised Danish and Norwegian website is live with active product listings. There are no signs of dormancy.
