NK CARE Smart Toothbrush with App

The NK CARE Smart Toothbrush connects to your smartphone via Bluetooth 5.0 and a companion app that tracks brushing duration, pressure, coverage, and technique in real time, providing actionable feedback to improve oral hygiene habits over time. An internal accelerometer and gyroscope detect the position and angle of the brush head sixteen times per second, mapping which tooth surfaces receive adequate attention and which are consistently missed. The app displays a 3D model of the mouth with color-coded zones — green for well-brushed, yellow for under-brushed, red for missed — updated live during each session. The brush itself delivers 42,000 sonic vibrations per minute through a diamond-shaped DuPont bristle head, with four cleaning modes: Daily Clean, Deep Clean, Whitening, and Gum Care. A pressure sensor flashes red and reduces motor speed when you press too hard, preventing enamel wear and gum recession. The rechargeable 2,000mAh battery provides 45 days of twice-daily use from the included inductive charging glass — set the brush in the glass to charge, and the glass doubles as a rinse cup. IPX7 waterproof. Weighs 4.5 ounces. Includes brush handle, charging glass, two brush heads, and a travel case.
