Study participants also said it was tied-with low and middle-for the most comfortable frequency.

We found only one small, old, imperfect study-funded in part by a grant from Rowenta, a German company that made electric toothbrushes at the time-that compared brushes with 2,100, 2,500, and 3,500 brushstrokes per minute and found that the middle frequency was the most effective at removing plaque (“at most 1.5 times better” than the other frequencies and yielded “about 50% more plaque free sites” than the highest frequency).
There isn’t a proven difference in effectiveness between faster and slower brush movements in existing independent research. These brushes also tend to move at a higher frequency, to the tune of 30,000 to 40,000 movements per minute, as opposed to a lower-end brush’s 8,000 to 20,000 movements per minute. Spend around $70, about 40% more than the cost of our top pick and your brush likely comes with a travel case and a few extra cleaning modes, which vibrate the brush at different patterns or frequencies. Some people find this feature incredibly useful. Pressure sensors that buzz, beep, or light up can let someone know when to let up while brushing. Pressure sensors: Some people have the tendency to brush too hard, which can cause gum damage, among other issues.“Sonic” toothbrushes, like those from Philips Sonicare and Waterpik, tend to be quieter and have a vibration-like movement, and oscillating brushes, like Oral-B’s, are louder. Ultimately it is a matter of personal preference. They all said the type of brush doesn't matter. We asked all the dental experts we spoke to if certain brushes could remove more plaque than others. A pleasing vibration or oscillation: Some electric toothbrushes vibrate back and forth, some have more of an oscillating, or rotating, motion.We eliminated models from our consideration that customer reviewers have said bricked shortly after a warranty period expired. Warranty coverage: Ideally, an electric toothbrush should be covered by a warranty for at least a year.Customers can request a free two-prong plug adapter from Philips Sonicare.Īpproximate cost of ownership ($50 brush handle + four Philips Sonicare replacement heads) after: Since October 2021, the charging pedestal that accompanies any new 4100 has only a USB plug.

However, the 4100’s battery lasts longer on a full charge than that of the Pro 1000. The 4100 runs much more quietly than the Pro 1000, but unlike the Pro 1000, it comes to a full stop after two minutes of brushing (rather than restarting the cycle as the Pro 1000 does) and has a less diverse, more expensive range of brush heads, giving you fewer options for head shapes and bristle textures.

Like the Pro 1000, the 4100 has a two-minute timer with quadrant pacing plus a pressure sensor and is not trumped up with unproven features. If you can’t find the Oral-B Pro 1000, or if you prefer a quieter brush with a head that vibrates back and forth instead of oscillates, we recommend the Philips Sonicare 4100. The biggest drawback: It’s louder than other brushes we’ve tested.Īpproximate cost of ownership ($45 brush handle 1 + four Oral-B replacement heads) after: Fully charged, it lasts for at least a week of twice-daily two-minute brushing sessions before needing a recharge, which is on a par with the other toothbrushes we tested in this price range and plenty for most people. The Pro 1000 comes with a minimalist charging pedestal that simply requires dropping the brush onto a peg. Our testers have found its oscillating brushing motion especially effective: It feels plenty powerful to deliver a reliable cleaning. It also has a pressure sensor to let you know when you’re brushing too hard. The Oral-B Pro 1000 toothbrush, which is compatible with nearly all the brand’s replacement brush heads, has an onboard two-minute timer with helpful quadrant pacing, keeping you on task (moving the brush around your mouth, cleaning all your teeth) for the recommended amount of brushing time.
