Once you're an adult you only have the one set of teeth, so it's worthwhile to take care of them for that reason alone, if not for the fact that poor oral hygiene has also been linked to other surprising health problems like heart disease. But brushing your teeth correctly isn't as easy as it seems, and some of us need some help to do it right. Oral-B Triumph to the rescue! It tells you where to brush and for how long, and even warns you if you're pressing too hard. It has 4 cleaning patterns to choose from and personalize, and it syncs up with a handy mirror-mounted LCD screen to keep you constantly in the loop on how you're doing. Expect them in September for about $150 (I guess fanciness like this doesn't come cheap!).
