Are you brushing your teeth correctly? You've been doing it since before you started preschool—but there's a good chance you never actually mastered this basic life skill. Most people brush too aggressively, or they don't do it for long enough (you're supposed to lather up for 2 full minutes!), or they fail to hit the hard-to-reach teeth in the back.

That's why lots of dentists recommend using an electric toothbrush. Earlier this year, set out to find the best electric toothbrushes you can buy, and although dentists recommend several models at a variety of prices, there was one we kept hearing over and over again: the Philips Sonicare Diamond Clean. It retails for a whopping $199, but for Amazon Prime Day, it's $99.95—50 percent off, and the first time we've ever seen it for under $100.

Sure, that's still a lot to spend on a toothbrush. But the dentists we spoke to say it's worth every penny: “Sonicare toothbrushes are powerful, durable, and reliable,” said Adam Salm, DMD, a dentist at Madison Dental Spa in New York City. "This one contains smart sensors that give people feedback about their brushing techniques and helps them be aware of which habits are hurting or helping their oral health.” Plus, you get a personalized clean, said Kevin Sands, DDS, cosmetic dentist in Beverly Hills. "It has four different intensities, so it’s great for people with sensitive teeth and gums or people who want a more intense brushing,” he explained. What's more, a built-in timer ensures you spend enough time brushing each part of your mouth, said Giri Palani, DDS, a cosmetic dentist in California.
