Battery life is excellent—lasting about two weeks per charge in our tests—and unlike Oral-B, the 4100 shuts off after the two-minute timer. It’s also designed with BrushSync technology, which tracks how long you’ve been using your brush head and how much pressure you’re applying. A light on the handle and a beep remind you when it’s time for a replacement—a thoughtful touch.
Unlike the Oral-B brush’s standard black and white, the Sonicare 4100 also comes in pink, azure blue, and dark forest green, which might not seem like much, but even the smallest pop of color can make a mundane task feel a little less … mundane.
Best Oscillating
The Oral-B Pro 1000 has been around since 2012, outlasting and outperforming flashier models because it’s powerful and priced right. The high-power motor stays focused on your teeth, so you won’t feel that hand-numbing vibration along the handle. If you’re switching from a manual toothbrush, the intensity might be startling initially, but you’ll adjust.
With just one button and three brushing modes (Daily Clean, Whiten, and Sensitive), the Pro 1000 keeps it simple. A built-in timer pulses every 30 seconds to remind you to move to another quadrant of your mouth, with a triple pulse at the two-minute mark. Unlike some competitors, it won’t shut off automatically, which is handy if you like to keep brushing. Oral-B says the battery lasts about a week, but we squeezed out 10 days in testing. That’s decent, though not as long as some other models.
Like all of Oral-B’s electric brushes, the Pro 1000 uses an oscillating brush head, which is a small, circular design that gets between teeth more effectively than larger oval-shaped bristles. Round brush heads tend to be easier to maneuver for those with smaller jaws, and they reach the back of the farthest molars. Though we haven’t tried all of them, most Pro models are a good bet.
