In 2008, Salton Corporation’s new owners decide to exit the oral hygiene market and since then, several new companies started selling ultrasonic toothbrushes such as the Ultreo®, Megasonex®, Smilex® and Emmi-Dent® brands.
Podjetje Sonex se je nato prodalo podjetju Salton, Inc., ki je začelo distribucijo izdelkov v ZDA in številnih drugih državah.
