When it comes to brushing teeth, it is easy to skip a few steps that seriously affect oral hygiene. Oral Guard features a number of functions that improve oral health. The device is equipped with a two-minute brushing countdown timer to help people brush for the right length of time. The 90-day toothbrush head replacement reminder solves the problem of keeping the same toothbrush head for too long. The case is equipped with a dryer to avoid any build-up of bacteria, a common problem on moist toothbrushes. The case also sterilizes the toothbrush with O₃ disinfection, which removes 99.9% of the bacteria on the toothbrush. Plus, the device's inverted charging system solves the problem of always forgetting to charge the toothbrush or locating the charging base.
