Philips Sonicare ExpertClean 7500 vs. Rotating Heads… Tested for Surprising Oral Power! We recently compared the Philips Sonicare ExpertClean 7500, a rechargeable electric toothbrush (HX9690/05), to rotating head models and were intrigued by its advanced sonic technology. Our tests revealed a distinct difference in efficiency. The ExpertClean 7500’s 62,000 movements per minute and premium bristle design created a thorough clean, noticeably reducing plaque in just two minutes. Unlike rotating heads, which rely on friction, the Sonicare’s oscillating action reached deep between teeth and along the gumline effortlessly. We appreciated the ergonomic grip and customizable modes, which suited our varying needs. While rotating heads have their merits, our results showed the ExpertClean 7500 delivered superior oral care with less effort. It’s a clear winner for those seeking power and precision.
