Portable Oral Care for Children

The Waterpik T40 is a cordless water flosser designed for ages six and up. Its lightweight, ergonomic body fits small hands and encourages independent daily use. The 180 ml tank provides enough capacity for a full cleaning session without refilling. Four selectable modes match different developmental stages and sensitivity levels.

Fits Home, School and Travel Routines

The compact dimensions of 14.33 in by 12.83 in by 9.06 in allow the unit to slip into a backpack or luggage. A rechargeable battery reaches full charge in 24 hours via any standard USB Type-C power source, so no proprietary adapter is required. IPX7 waterproofing means the device can be rinsed safely under running water. The 360-degree rotating nozzle and quick-change tip system simplify positioning around teeth and braces.

Accessories That Support Daily Habits

Four storable nozzles are included, each suited to a specific mode or user preference. Colorful DIY stickers let children personalise the handle, turning oral care into a more engaging activity. A battery indicator shows remaining charge at a glance, while the non-slip grip and leakproof tank design reduce mess during use. All components are BPA-free for added peace of mind.
