O''fresh / Dental care product


During working or studying hours, because of annoying tooth brushing tools and steps, people might neglect to clean their oral cavity which leads to serious diseases. Therefore, we designed O’fresh to provide a simple, and efficient teeth cleaning with ultrasonic waves and hydro-electric solution which can wash away food debris and sterilize easily. Also, if the detecting pH value of your oral area is out of the normal range, O’fresh will connect to your smartphone to inform you and advise further actions. It is charged by inductive charging box with UV sterilization. As a whole, O’fresh refreshes your breath, and improves your health.
