On 'White Teeth Day' (April 8), Oh my teeth launches full-scale 'Dual Whitening' service, born from user feedback: 'After straightening, I want to whiten.'

Oh my teeth Inc. (hereafter, Oh my teeth), Japan's No. 1 manufacturer of clear aligner brands(*2) with over 10,000 cumulative orthodontic graduates(*1), is pleased to announce the full-scale launch of "Dual Whitening" at Oh my teeth partner clinics, coinciding with "White Teeth Day" on April 8.

This service was developed in response to insights from users post-treatment, who expressed a desire to "pursue greater whiteness now that their teeth are aligned." The whitening service already offered at partner clinics has surpassed 1,000 cumulative bookings(*), and to meet further demand, a high-performance plan combining office and home whitening will now be available at each partner clinic.

 *: Cumulative bookings from October 4, Reiwa 7 to March 18, Reiwa 8.
 *1: Total number of cases where treatment was completed between December 1, 2019, and May 26, 2025.
 *2: No. 1 in domestic clear aligner brand manufacturing (surveyed by GMO Research & AI Inc. in January 2025, covering Jan-Dec 2024, for domestic clear aligner brands).

◾️ The Pursuit of the "Ideal Smile" Doesn't End with Orthodontics 

With the mission to "deliver the dental experience of the future," Oh my teeth has provided a clear aligner system that, in principle, requires no hospital visits(*3). As many users graduate from their treatment, the specialized support team on LINE has received numerous comments like, "Now that my teeth are straight, I want to be even more particular about their whiteness and cleanliness."
In response to this user enthusiasm and the fact that cumulative bookings for whitening-related services have exceeded 1,000(*), Oh my teeth concluded that it should provide a professional experience not only in "teeth alignment" but also in "whiteness." This led to the development of the "Dual Whitening" system and support for its implementation in partner clinics.

 *3: Depending on the condition of your teeth, multiple visits may be necessary.
 *: Cumulative bookings from October 4, Reiwa 7 to March 18, Reiwa 8.
