Dentists insist that more attention and efforts should be paid into the prevention of dental caries in children. However, conventional brushing can only cover 60% of the total teeth surface, remaining lots of food debris and bacteria in hard-to-reach areas. Therefore, child water flossers are highly recommended in an effort to prevent cavity and other oral diseases. K30, a child water flosser designed for children aged 6-12 years with safety, efficiency and fun as its core, features an adorable style, child-specific flossing modes, and all-round safety designs. It can accompany children throughout the dental transitional period, helping them prevent caries and other oral diseases whilst also cultivating their awareness of oral hygiene.。For easier operation, its display and operation buttons are highlighted by simplifying other elements on the shell. On its back are the grooves ergonomically designed for an easy grip. Children can hold it comfortably, with their thumbs resting naturally in the button area.。More highlights of the K30 are its child-fun design and various adorable trims, making this product attractive and suitable for children across all age groups, while mitigating children's resistance to water flossing.。。It comes with two safety designs. One is the smart water control performed by its upper laser sensor, which can sense the teeth and offer/stop water flossing when the nozzle is in/out of the mouth — that avoids spraying water on the face or into eyes. The other is the child-specific nozzle with a built-in rotator for gentle rinsing, as it can spray water in a flat form to disperse the pressure at one point over a larger surface. Even better, the water pulse strength and frequency tailored for children can rinse food residue away for a thorough cleaning result, and protect their tender gums from excessive pressure of water pulses.
