"People should feel confident that their toothbrush helps them achieve a great clean every time, especially given the established connection between oral health and overall health," said Matina Vidalis, Regional Business Unit Leader, Oral Healthcare, Philips Personal Health North America. “Grounded in more than 50 years of oral care expertise and clinical heritage, our Next-Generation DiamondClean brings highly intuitive coaching directly to the handle.

The launch comes as new research shows brushing competes for attention at bedtime. According to a recent Philips Sonicare ‘Distracted Nighttime Brushing Study,’** conducted in May 2026, 82% of Americans multitask during their nighttime routines, rising to 92% among adults under 40, and 47% say they rush through brushing as a result. People surveyed also highlight a critical gap where confidence doesn’t always mean full coverage: while 91% of Americans say their teeth feel clean after brushing, 66% believe they miss areas.
