Our Favorite Electric Toothbrush Is 40% Off Right Now for Prime Day (2025)

Lab notes: With tens of thousands of five-star ratings on Amazon, this brush is best for anyone looking for a basic but effective electric toothbrush that will deliver a solid clean without any fancy bells and whistles. Our Lab pros gave it a perfect score for effective cleaning teeth and a nearly perfect score when compared to a professional teeth cleaning. Our experts were also impressed by the ease of use, its rotating head for plaque removal,
a pressure sensor to prevent over-brushing and a two-minute timer. Plus, the cost is lower than comparable options.

Tester feedback: "This Oral-B brush has the perfect little angled brush that gets in between my teeth and gets all the plaque and food out that is hard to get with a traditional toothbrush," said one tester. Consumer testers also liked its lightweight, user-friendly design (although there is only one cleaning mode and no adjustable speed), though we noticed it was noisier than other models and some residue on the charging base after extended use.

App integration: This toothbrush offers great value, but it lacks some of the advanced features found in pricier models, like app connectivity.

Cleaning performance: 4.9/5

Lab notes: We love that the Sonicare 4100 offers all of the brand's must-have features at a great price, including a two-minute timer, pressure sensor and two intensity settings, which are especially helpful for sensitive gums or teeth. In our tests, it received nearly perfect scores for its ease of use, durability and quietness. It has a lightweight design and compact USB-A charger for easy storage. Its performance scores were slightly lower than premium Sonicare models, but you can get it for an eight of the cost.

Tester feedback: Many of our consumer testers felt it thoroughly cleaned their teeth. “I felt like I got a great clean each time with minimal effort,” said one tester. Another appreciated the brush head’s design: “The compact head fits farther back and reaches all around the back teeth better than a manual toothbrush.”

App integration: There is no app or connectivity for this toothbrush.

Cleaning performance: 4.5/5

Lab notes: While it might be the most expensive on this list, it earned the highest overall score in our Lab tests.

Earning top Lab and consumer satisfaction scores, the Sonicare 9900 Prestige offers the most advanced features of all the toothbrushes we tested, like sensing your brushing movements, adjusting vibrations to protect teeth and gums, tracking missed spots and more. Two intensity settings let you customize your experience, and the connected app helps improve brushing habits over time.

If you prefer the look and feel of a traditional toothbrush, you’ll likely gravitate toward Sonicare's elongated brush head. Its rows of side-to-side moving bristles and narrow shape make it easier to reach tricky spots in your mouth.

Tester feedback: Our pros weren't the only ones who loved this brush — it received the best consumer satisfaction score. Several testers felt they had healthier gums and less plaque after using it. "I love this toothbrush," said one tester. "The vibrations tickle a bit and take a few days to get used to, but they make it super effective. My teeth feel like they’ve been professionally cleaned," another shared.

"The toothbrush is beautifully designed and takes up very little space in my bathroom," one tester explained.

App integration: This toothbrush pairs with the Sonicare app to guide you through brushing and alerts you to any missed spots. The brush automatically adjusts the intensity and vibrates if you brush too hard, which is helpful for sensitive gums. "The app is easy to use, makes brushing fun, and motivates me to brush more often," said one tester.

Cleaning performance: 4.7/5

Lab notes: The iO Series 9 is one of Oral-B’s most advanced electric toothbrushes, and while it’s on the pricier side, it’s packed with smart features for a deep clean. In Lab tests, the Oral-B iO scored highly across the board. And with seven smart modes — including one for tongue cleaning — plus a built-in timer, Smart Pressure Sensor (which turns red if you're brushing too hard), a charging travel case and three replacement brush heads, it offers a premium brushing experience.

Tester feedback: Consumer testers were impressed, calling it “a game-changer,” “a joy to use” and “incredibly cool.” Many even said it felt like a professional cleaning: “What’s not to love? I’m addicted to brushing my teeth with this toothbrush! It feels like I just left the hygienist,” one tester shared.

App integration: The app includes real-time AI "coaching" to guide you as you brush, ensuring you never miss a spot. Testers praised the app and the multiple cleaning modes. “I like the functions. The sensor light shows if you’re using the right pressure, and the app tracks how thoroughly you brush, offering feedback for improvement,” said one tester. Others loved the interactive color display, which shows a smiley face when you’ve brushed for two minutes.

Cleaning performance: 4.4/5

Lab notes: SuperMouth, a Good Housekeeping Parenting Awards winner, makes oral care fun for kids ages 6 and up with superhero and supervillain-themed toothbrushes that are as cute as they are effective. Each toothbrush offers three speeds — light clean, super clean and massage — so you can adjust the brushing intensity. The gentle bristles are soft on young gums, and replacement heads are priced at $10 each.

Tester feedback: Our parent testers loved that these brushes made teeth-brushing exciting for their kids, with one mom sharing, "My son now runs to the bathroom to brush his teeth" and others deeming it a "big win."

• Laifen Wave: This sleek and compact toothbrush stands out for its unique head movement, according to our testing experts. The head oscillates with a “pivoting” motion that sweeps up and down over the teeth. The vibration may be too strong for some, but there are three modes so you can adjust. We do like that replacement heads are affordable at $10 for 3.
• Oclean X Pro Digital Sonic Electric Toothbrush: This sonic toothbrush impressed our testers with its effective performance and design that features an innovative smart screen for instant feedback on how well you cleaned. Claimed battery life is up to 30 days and at $100, we think it offers good value.
• Oral-B iO Series 2: The latest addition to Oral-B’s iO Series lineup, this toothbrush offers iO technology at an accessible price point. While it’s not as feature-rich as the Series 9 on our list, we love its user-friendly design and solid performance that’s not only quieter but gentler on the gums than the Pro Series.

Our electric toothbrush reviews are based on extensive in-Lab tests at the Good Housekeeping Institute. In our latest evaluations, we tested over a dozen electric toothbrushes in our Labs for performance, ease of use and durability.

We also sent samples to over 100 consumer panelists who reported good dental hygiene habits (brushing twice a day and having a professional cleaning every six months) to provide qualitative feedback on each toothbrush. After two weeks of use, they were asked to evaluate their overall satisfaction. Here's how we scored:

✔️ Performance: Product analysts evaluate the toothbrush’s overall functionality, its modes and how effectively it cleans teeth. We then measure battery life, charging time, the accuracy of the two-minute timer and the usefulness of any built-in sensors. To evaluate and compare noise levels in each toothbrush, each toothbrush is sent to Quiet Mark, our partner lab and independent global certification program that identifies how quiet or loud products are through scientific testing and assessment.

✔️ Durability: Each toothbrush is put through a drop test and a water-resistance test in our Lab to score its durability. For the drop test, each toothbrush is dropped from a 30-inch height, or the average height of a countertop, and then checked for any dents, scratches or damage. The water-resistance test is then performed in the Lab’s rain tester, exposing the toothbrush to various water pressures for two minutes.

✔️ Ease-of-use: Once the toothbrush has been measured and weighed, we provide feedback alongside consumers on the following questions: How easy is it to set up? How easy is the toothbrush head to put on? Are the controls conveniently located and easy to use? Is the toothbrush easy to charge? Is the app intuitive? Is the design ergonomic and easy to hold? Is it heavy or lightweight? Did the toothbrush create a mess while in use? Does its size take up too much space?

✔️ Power source: In our Lab tests, people greatly preferred rechargeable options to battery-operated ones. Our feedback showed the battery-operated brushes were ideal for travel, but they didn’t work as well as electric toothbrushes with rechargeable bases.

✔️ Timer: Many electric toothbrushes offer a timed brushing setting of two minutes, broken up into 30-second intervals, so you're thoroughly paying attention to your teeth — front to back and top to bottom.

✔️ Pressure sensor: Avoid sensitive gums by finding an electric toothbrush that gently vibrates when you press down too hard.

✔️ Connectivity: Certain electric toothbrushes feature Bluetooth technology so you can sync to an app to keep track of your brushing habits and access extra features like coaching and tips. Some of the more premium toothbrushes even leverage AI technology to give you feedback in real-time as you brush to understand which areas need improvement.

“Not all electric toothbrushes are created equal,” says Sharon L. Huang, D.D.S., owner of Les Belles Dentistry in NYC. She estimates that two minutes with an electric toothbrush is equivalent to seven minutes of manual brushing.

Why? Because electric toothbrushes are more efficient at cleaning and more effective at reaching a lot of surfaces, especially hard-to-reach areas like molars in the back of your mouth. “When you use a manual brush, it depends on how you’re brushing [and the motion] versus an electric toothbrush which does the work for you,” she says.

Simply put: “We will never move as fast as a sonic brush,” which she favors for its power and ability to dislodge bacteria.

"Pretty much everyone can benefit from an electric toothbrush,” says Jamie Reynolds, M.D., an orthodontist based in Michigan. After he switched to an electric toothbrush, his own dental hygienist commented on how clean his teeth looked. “Personally, I won't be switching back to the old-fashioned way and don't recommend you do either!”

But remember, no matter which powered toothbrush you buy, the most important thing is your habits, says Dr. Reynolds. “An electric toothbrush isn't a magic wand. It still requires morning and night use — with around two minutes of brushing time — to be effective.” Use it as a way to up your brushing technique, not make up for it.

The Good Housekeeping Institute’s Beauty, Health & Sustainability Lab regularly tests oral care items like whitening toothpastes and baby toothbrushes.
