Inspired by dental professionals, this rotary toothbrush utilizes UV light to kill harmful bacteria—helping to keep your brush, and your mouth, clean and healthy. High speed sonic waves (over 30,000 pulses per minute) prevent gum irritation as it works deep between teeth to remove plaque from hard to reach places, and to remove tough surface stains for naturally whiter teeth. With 3 modes of operation—normal, soft and massage, timers for brushing and sanitizing, LED charging indicator and color ID rings for stand (holds 4 brush heads). Dual voltage for international travel. 4" w x 5" h x 3 3/4" d.
