"  What are they going to stick Bluetooth in next, a toothbrush? Absolutely, though Oral B was smart enough not to use the dreaded B-word when marketing its new electric toothbrush, the Oral-B Triumph with Smartguide. The rotating brush head transmits information to a small display\u2014the Smartguide\u2014showing how long you&amp;#039;ve been brushing, which of four modes you&amp;#039;re in (for example, a softer mode for sensitive teeth or a feverish scrub for stain removal), and, most important, whether you&amp;#039;re brushing too hard. On the otherwise monochromatic display, a red warning icon pops up when the head senses too much pressure. While a simple warning beep would serve the same purpose, there&amp;#039;s something mesmerizing\u2014even rewarding\u2014about intently watching that little Smartguide screen bearing down on your molars &amp;#039;til you see red, backing off, then forcing the issue again. I hate to say it, but this is interactive brushing, with embarrassingly simple icons. There&amp;#039;s even a happy face that gets happier the longer you brush, inspiring total user obedience. Or maybe I&amp;#039;m particularly susceptible to machine commands. The Smartguide, which you can mount on a wall or carry around as you pace the halls brushing, recognizes at least four different heads, just in case you want to share the brush-plus-display with your family, roommates or other brushing enthusiasts. Sharing isn&amp;#039;t a bad idea, considering the $150 price tag, but this model is in line with other high-end electric toothbrushes. The Smartguide also tells you when it&amp;#039;s time to replace the head, which I&amp;#039;m excited about ignoring in around two and a half months. Will the happy face frown? Will lines furrow on its little brow? If it starts beeping at me, I&amp;#039;ll go back and edit this review in a big way. But until then, this is the best, smartest toothbrush I&amp;#039;ve ever used. And it probably knows it, too. \u2014Erik Sofge "^^<http://www.w3.org/2001/XMLSchema#string>
