Our Favorite Electric Toothbrush Is 40% Off Right Now for Prime Day (2024)

Trade in your standard toothbrush for the best affordable electric toothbrush out there. With tens of thousands five-star ratings on Amazon, it's no surprise this Oral-B is a top performer in our Lab tests. In fact, this brush received some of the highest overall scores, standing out for exceptional performance, ease of use and consumer satisfaction.

This electric toothbrush offers all the key benefits — like a rotating head for plaque removal, a pressure sensor to prevent over-brushing and a two-minute timer — at a fraction of the cost of many others on the market. While it only has one cleaning mode, the controls are easy to navigate without being overwhelming, and it delivers an effective clean. "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, though our in-Lab testers noted it was noisier than other models, and we noticed some residue on the charging base after extended use.

Keep in mind that while this toothbrush offers great value, it lacks some of the advanced features found in pricier Oral-B models, like adjustable speed or sensitivity settings. It's best for anyone looking for a basic but effective electric toothbrush that will deliver a solid clean without any fancy bells and whistles.

Curious about Sonicare’s powerful plaque-removing technology but not ready to splurge? 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.

While it doesn’t come with a travel case, its slim, lightweight design and compact USB-A charger make it convenient for travel.

Though its performance scores were slightly lower than premium Sonicare models in our Lab tests, this toothbrush stood out for its ease of use, durability and quiet operation. 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.”

Ever wondered what toothbrush your dentist uses at home? It's probably the Prestige 9900. While it might be the most expensive on this list, it earned the highest overall score in our Lab tests, as well as the best consumer satisfaction score.

It pairs with the Sonicare app to guide you through brushing and alerts you to any missed spots. If you have sensitive or receding gums, no worries — it automatically adjusts the intensity and vibrates if you brush too hard.

Several testers felt they had healthier gums and less plaque after using it. "I love this toothbrush," said one tester. "The 9900 is very quiet. 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! The app is easy to use, makes brushing fun, and motivates me to brush more often. Plus, the toothbrush is beautifully designed and takes up very little space in my bathroom."

Testers also appreciated the ability to customize their brushing routine with five different modes and loved the compact travel case. You can even charge the toothbrush via USB in the travel case, leaving the charger at home.

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.

For example, it includes real-time AI "coaching" to guide you as you brush, ensuring you never miss a spot. 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.

In Lab tests, the Oral-B iO scored highly across the board. 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.

Testers also 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.

It’s easy to forget that you should replace your toothbrush (or brush head) every three to four months — yes, really! That’s why we recommend Quip. Not only is the battery-operated brush sleek and slim, but it also offers a convenient refill plan. For just $7 per order, you can have a new brush head and battery delivered every three months, making it a great value for the whole family, including kids.

We especially like Quip for travel, thanks to its slim cover that easily fits in a purse or backpack without taking up much space. Unlike other electric toothbrushes, Quip uses AAA batteries, so you don’t have to worry about chargers or cables while on the go — although a rechargeable version is available, lasting three months between charges.

In our Lab tests, Quip received high scores, with users praising its soft bristles and gentle sonic vibrations. “It actually makes me brush for the full two minutes. My teeth feel so much cleaner after just two weeks!” one tester shared. Testers also liked its compact size, making it easy to hold, use and store. However, some noted that, unlike other electric toothbrushes that do most of the work for you, you still need to put some manual effort in with Quip. They also felt the instructions for replacing brush heads and batteries could be clearer.

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. 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.
