If you love a toothbrush with a powered assist or find an automated two-minute timer helpful, it’s time to upgrade from a manual to an electric toothbrush. After long research hours interviewing dental hygiene experts and considering nearly every available electric toothbrush model, I’ve come up with a list of the best sonic toothbrushes.
In search of top-notch electric toothbrushes, I bought 15 of them and brushed my teeth—a lot — while consulting and checking out all features with dental professionals. I did all this to ascertain which features were helpful. At the end of the testing period, I found nine great models to get your oral health dialed in.
This review looks into the best sonic toothbrush and shares some commonly asked questions about electric toothbrushes.

Best Sonic Toothbrush: How to Test Your Sonic Toothbrush
All electric toothbrushes have the same testing protocol. First, run the toothbrush through various settings and check its noise using a decibel counter app. After that, compare it to other gadgets and their levels of noise. This test helps you determine whether it matches your acceptable noise levels.
Consequently, you should utilize the toothbrush in its different modes and settings, taking note of the differences in durations and intensity in-between settings. Furthermore, you must test the charger’s duration to fully charge and how long it takes before the battery depletes.
These tests help you determine what you’ll get from your sonic toothbrush.
Which is the Best Sonic Toothbrush?
Here are some varieties to choose from:
Put the best smile forward with this white sonic toothbrush. To achieve the smile of your dreams, you need a toothbrush equal to the task. This Dr. Brite sonic toothbrush is an at-home professional teeth cleaner that’ll leave your teeth sparkling after every use.
Enjoy the waterproof sonic toothbrush with long battery life and a fast-charging wireless base. Its new package includes;
This sonic electric toothbrush is available in black and white, and Dr. Brite sells all brush heads separately.
- It has four brushing modes; Gum care, polish, white, and clean.
- Its advanced sonic cleaning technology features 38,000 strokes per minute for powerful and dynamic cleaning action. It helps remove 100% of plaque from hard-to-reach areas.

Are you searching for the best reasonably priced toothbrush? If so, this Phillips Sonicare 6100 is an upgrade from the Philips Sonicare 4100, which has a similar feel and appearance. The 6100 has been in the market for decades and is comfortable and effective.
This model has simple yet practical features like a timer and pressure sensor that set it apart from a traditional manual toothbrush. In addition, the toothbrush has an oscillating head, which adds pressure for more effectiveness. It’s also loud enough and sounds like a freight train passing through your bathroom.
This 6100 version has 3 intensity levels with 3 modes—an automatic timer, whitening and gum care, and the default clean mode. To get the most out of these three modes, the manufacturer suggests buying brush heads designed to perform best with the brush.
Furthermore, the brush has a pressure sensor indicator, 14 days of battery life, a replacement brush heads reminder, and a two-year warranty. Also, it comes with a travel case that fits the toothbrush and two heads.
The major highlight of this toothbrush is that it reminds you when to get replacement brush heads using the BrushSync technology. It lets you know how long you’ve been using the brush head, how hard you’ve been brushing, and your brush performance and cleaning. A light on the handle blinks, and the brush beeps, prompting you to order a new brush head.
If you’re looking for a toothbrush specializing in teeth whitening or gum care, this is your choice.
Pressure Sensor, Brushing Timer, Customizable
2 Weeks; Rechargeable
- It’s gentle yet effective and can whiten teeth in just one week compared to a manual toothbrush that takes longer.
- Protects teeth with its pressure sensor and gently pulses to send alerts when you brush too hard.
- Has a toothbrush head replacement reminder that lets you know when to make a replacement.
- Offers three intensities and modes that let you personalize your brushing experience: clean, white, and gum care.
- The two-minute timer with a QuadPacer lets you adhere to the dentist-recommended brushing time and consistently clean the mouth.
- Even with more features than its predecessor, for a higher price range, the enhancements don’t add up to the price difference.
- Using the different brushing modes regularly drains the battery, so you’ll need to charge it on time.
After testing some of the best electric toothbrushes, I discovered this Oral-B Pro 1000 CrossAction toothbrush has features that match its price point. This simple yet efficient toothbrush offers the most basic functions compared to high-tech options.
In fact, it performs well enough, like other electric prices, twice or thrice its cost. Its features include a quadrant timer that goes off after 30 seconds to signal you to switch to a different section of the mouth, ensuring you clean all areas. On the other hand, a pressure sensor lets you know when the pressure on the teeth and gums becomes too much.
Suppose you desire an electric toothbrush to amp up your oral hygiene. The Pro 1000 is among the easiest to operate—no brushing barriers exist. Moreover, its few features are equally effective and offer enough guidance without being overwhelming.
This Pro 1000 has a timer that alerts you every 30 seconds to change quadrants and also notifies you when two minutes elapse. Its pressure sensor tells you when you exert too much pressure while brushing, though the alerts are more subtle.
The singular brushing mode feels comfortable yet thorough enough for a deep clean. The Pro 1000 performs at par or even better for plaque tests than more expensive models. Plus, its small, round rotating toothbrush head and bristles of different lengths reach the smallest of spaces in your teeth.
You’ll also love its ergonomic features, like the anti-slip ridged back that keeps it from falling off your hand while you’re brushing, and its lightweight, which ensures portability. The brush is also less noisy compared to other models, plus changing or cleaning the brush heads is an effortless task.
Overall, the Pro 1000 delivers more for less. It makes your daily dental hygiene routine pleasant and effortless.
Removes 300% more plaque than manual toothbrush, Daily Clean
- Clinically proven superior quality that pulsates and oscillates to clear up to 300% more plaque as opposed to manual toothbrushes.
- Its pressure sensor stops pulsation movements when you apply unnecessary force, and the handle timer lets you know once you brush for the recommended time.
- The brush is compatible with all Oral-B brush heads.
- It has soft bristles that rotate to break up and sweep away the plaque.
- Not suitable if you’re looking for an electric toothbrush with high-tech features.
Although this Philips Sonicare 4100 may not be as feature-packed as other cheaper electric toothbrushes, it still gets the job done. It has low and high-intensity levels and a one-brushing mode. Its straightforward controls allow you to change the settings and brush at the same time easily.
It felt extremely comfortable in hand during testing, and its toothbrush head was gentle to the gums and teeth as it got to the hard-to-reach sections. The best part? It left my teeth sparkling clean.
Its two-minute timer lets you know you’ve achieved the dentist-recommended brushing time. Even better, the ‘Quadpacer’ timer vibrates at 30-second time differences, guiding you to move the toothbrush to another mouth section. You may also choose to pause the toothbrush for a maximum of 30 seconds—still, the timer picks up from where you had left the brushing process.
The one thing that stands out in this toothbrush—something I didn’t find in other reasonably priced and among the best electric toothbrushes — is the pressure sensor. When brushing your teeth with an electric toothbrush, the brush head does all the work without needing to scrub. If you press too hard during the brushing session, this Sonicare 4100 vibrates, and its indicator light flashes a warning.
Dr. Mark Wolff, a restorative dentistry professor at the University of Pennsylvania, says you must control the pressure during brushing. Brushing with lots of aggression wears the tooth and gum structure, leading to tooth sensitivity to cold and recession.
Every feature on this toothbrush is well-thought-out. On the toothbrush’s backside, you’ll see a top-notch that keeps it from rolling around, ensuring it lies flat on the surface. And like with most Philips toothbrushes, it has a plastic case included for use during storage or travel.
- The easy-start program on this toothbrush allows a gradual, gentle progression in your brushing power in the first 14 uses after purchase.
- With a gentle buzz, the toothbrush reminds you to change to a new area in the mount every 30 seconds and signals when the 2-minute brushing time ends. This toothbrush gives you an optimal brushing experience every single time.
- It cleans those hard-to-clean areas five times better than a manual toothbrush.
- The brush is sensitive to dental work, orthodontics, and other sensitive areas. It allows you to brush safely on veneers, crowns, fillings, sensitive orthodontics, and braces.
- It has a short-life battery. I’d advise you to keep consistent charging times.
The Philips One by Sonicare is an excellent toothbrush with a form-fitting case that is a perfect fit for the toothbrush. It doesn’t take up space in the toiletry bag, which makes it an excellent travel buddy. In addition, it’s available in seven colors.
One of its major highlights is its 30-day battery life, which doubles or triples the battery life of most electric brushes. Thus, it allows you to focus on your brushing experience rather than the risk of running out of battery while on the move.
Furthermore, it has a no-charging base, and you can also charge the toothbrush using a USB-C cable. Although the USB-C is an addition to the toothbrush, you already know that if you leave it behind, chances are that you’ll find another one to use to charge the toothbrush. Also, a battery indicator notifies you of the amount of charge left, and if you deplete the charge, it takes eight hours for the toothbrush to charge fully.
Despite this toothbrush not giving alerts on pressure like the Sonicare 6100, you’ll love the 2-minute timer, and the quadrant indicator buzzes every 30 seconds. As with other Philips toothbrushes, you can restart from where you left off after the 30 seconds pause.
Something else I noticed about this model is that its replaceable brush head resembles a manual brush, and its W-shaped bristles reach tight spaces. These bristles are gentle and soft and leave teeth feeling cleaner than a manual toothbrush would achieve.
- This toothbrush is an excellent step up from the manual brush and has a battery life of up to 30 days.
- Its tapered bristles and micro vibrations gently polish your teeth and leave you with a brighter smile.
- Additions to the brush include one USB charger, a travel case, and a matching brush head.
- Has no pressure sensor
- No Bluetooth connectivity
Sleek and stylish, this Philips Sonicare DiamondClean 9300 features four brushing modes—deep clean+, white+, gum health, and clean. You can also tweak these settings further to suit you, thus giving you a broader brushing experience.
Another aspect of the toothbrush is the difference between the clean and deep clean+, which gives the teeth a clean feel. However, after cleaning the teeth a few times, there wasn’t such a big difference between the other modes, save for Gum Health being more tender on the gums.
In addition, the electric toothbrush comes with an app that helps you monitor your oral hygiene and reminds you when it’s time for a replacement brush head. There’s also the option for automatic re-ordering.
While the Oral-B app improves brushing techniques, the DiamondClean Smart 9300 app only records your brushing activity and the pressure applied during each session. Therefore, unless you wish to get reminders to brush each day or use minimal pressure on your teeth, you might not find the app helpful in any other way.
The central plus point for this toothbrush is that it has a USB-charging case, suitable for travel purposes. This electric toothbrush has enough features you’ll love, with or without the app.
What I love most about this Sonicare electric toothbrush is its ergonomic shape. It’s smooth and satisfying to hold, and the brush head design allows you to brush the back of the mouth easily. This sonic toothbrush is adaptable to your brushing needs.
Users also rave about this toothbrush, which has a high rating for its stain removal and deep cleaning, even with its almost zero volume.
- Offers a personalized brushing experience.
- Has an automatic pressure sensor.
- Syncs operating modes to the brush head.
- Has limited color options.
- The app has limited functions, which may be ideal for those looking for a toothbrush with minimal features.
This Oral-B iO Series 9 ranks among the best smart toothbrushes I’ve tested. It has an app that offers accurate and valuable feedback. This brush provides you with seven modes, the most out of the toothbrushes I’ve reviewed, along with features such as a two-minute timer and an easy-to-view pressure sensor.
Its seven modes include tongue clean, sensitive, super sensitive, gum care, whitening, intense clean, and daily clean. Dental hygienists note that while most people need a standard-mode electric toothbrush, a sensitive setting offers added benefits to those at risk of tooth sensitivity, gingival attachment, and enamel wear.
Furthermore, when paired with a compatible brush head, the gum care setting helps remove bacteria from the gums. This toothbrush allows a personalized experience thanks to the different modes for patients with specific oral needs. Also, note that its most authentic experience comes from pairing the right brush head with the selected mode.
This toothbrush’s oscillating brush rotates from one side to the other and produces less noise than other Oral-B toothbrushes in the same category. In addition, its round head pulsates, loosening plaque, and then rotates and oscillates, sweeping all plaque away.
It may seem overkill to some, but you’ll love Oral-B’s smart features. The features allow you to sync the toothbrush to the app on the phone and use it to guide your brushing sessions.
The app tracks the pressure applied during brushing sessions and the total brush time. This app also sends daily lessons according to your brushing habits, which makes you improve efficiency.
Although it has a higher price tag, its packaging comes with a travel case, a magnetic charger, and four brush heads. If you desire an electric toothbrush to help you stay on track with your brushing habits, this smart toothbrush is a favorite.
If you’re unsure whether it’s worth the investment, you can try it for 60 days. You can receive a full refund if the experience isn’t worth the investment.
- This toothbrush offers personalized brushing. Its display screens allow you to customize your brushing experience.
- It offers a deep clean thanks to its round brush head with twisted bristles.
- Allows you to experience live coaching by guiding you to 100% cleaning, ensuring you go through every single zone.
- Has a higher price range, but it’s still worth the investment.
The Brightline Rechargeable Sonic is among the best electric toothbrushes and is as simple as they come. The toothbrush may not have convenience features like LED indicators, a pressure indicator, or a pause-and-resume feature. But it still delivers basic electric toothbrush functionality.
The toothbrush is perfect if you wish to try an electric toothbrush without poking holes into your pockets. Unlike other toothbrushes with more features, this option doesn’t have an indicator for a low or high setting, meaning you should press and hold the brush’s power button to achieve your desired intensity.
Fortunately, this toothbrush keeps your vibration setting for the next brushing session. Another feature to note is its two-minute timer and the 30 seconds quadrant reminder, but it lacks the pause function. This electric toothbrush allows you to take a break as you brush, but the timer resets, meaning you can’t keep track of the 30 seconds or two minutes requirement.
A full battery charge lasts up to 25 days, making it easier to enjoy your brushing sessions longer without interruptions. Another win for this toothbrush is the relatively inexpensive replacement heads, which makes having a Brightline toothbrush a better idea than other brands.
Replacement brush heads for this electric toothbrush aren’t too expensive. When purchasing, the box comes with two heads. Still, a four-pack would cost you less than $10. At $2.50, this price point makes owning a Brightline more economical than other brands.
When you buy this toothbrush, you’ll find a complete starter kit with two brushing heads, one charging base, and one rechargeable toothbrush. The package lasts you for up to six months.
Electric, Battery Powered
- A well-built toothbrush for healthy teeth doesn’t have to cost an arm and a leg. This Brightline toothbrush provides top-quality performance at an affordable price range.
- Its long-lasting rechargeable battery lasts up to 25 days between charges, making this toothbrush the ideal choice for daily brushing and traveling.
- The adjustable intensity allows you to customize your brushing experience using the adjustable intensity setting. Once you identify the right vibration, the Brightline toothbrush remembers each time you turn it on.
- This toothbrush has the American Dental Association’s approval seal.
- The primary downside is that this electric toothbrush lacks a pressure indicator—one of the highly recommended features by dental professionals.
- It’s bulkier than most powered toothbrushes and has limited head options, but it still does well.
Water flossing is a game changer. No joke! If you’ve always hated flossing, Waterpik makes flossing efficient and incredibly easy. With minimal effort and the shortest possible time, the Waterpik water flosser removes the tightly held food debris from your teeth. You should also use it underneath metal retainers, which can take over 20 minutes if you do it manually.
Using the water flosser is a revelation that makes you wonder whether flossing can be that easy and why you never discovered it soon enough. It takes your dental hygiene a notch higher than just using random electric toothbrushes.
Moreover, the Waterpik Complete Care 5.0 comes at a reasonable price compared to purchasing an electric toothbrush and the water flosser separately. The two-in-one gadget offers you five water flosser tips, a 2-minute timer with quadrant pacing, ten pressure settings, and two triple sonic brush heads.
Well, it takes some time to get used to the Waterpik because you have to learn how to bend such that you have your mouth at the top of the sink. That said, you might need to take the water flossing gradually if you have sensitive gums. Start the water flosser at a low setting and slowly work your way up as your gums become less sensitive.
Because not all flossers are the same, choose the Waterpik brand for next-level oral hygiene.
- Waterpik invented the flosser in the 1960s, and it has undergone years of innovation to date.
- It passes the ADA standards for effectiveness and safety.
- 9/10 dentists recommend it over other water flosser brands.
Gum Health, ADA Accepted, Removes Plaque, Prevents Cavities
- The water flosser is a 2-in-1 gadget that allows you to floss and brush simultaneously.
- It comes in three modes, and at a push, you can floss, brush, or you can opt to do both, which makes it easy to take care of your oral hygiene with just one device. This toothbrush is two times better and reduces plaque and improves gum health.
- 9 out of 10 dentists recommend the Waterpik water flosser, which possesses the American Dental Association (ADA) Seal of Acceptance.
- When you purchase this water flosser, it includes the global voltage 100-240 VAC, 50/60 Hz, travel case, two brush head covers, two flossing brush heads (one full size, one compact), 16 oz detachable reservoir for filling and cleaning with ease, and a professional flossing toothbrush.
- If you have sensitive teeth, you should begin flossing at a minimal intensity and increase gradually as the gums adjust.
Everything You Should Know About the Best Electric Toothbrushes
There are specific vital functions you should identify in sonic toothbrushes:
It’s advisable to brush for the required two minutes. Thus, all the above toothbrushes have a built-in two-minute timer that ensures you don’t cheat on your brushing time. In addition, the toothbrushes include 30-second vibrating alerts that remind you to move to the next quadrant.
Other toothbrushes, though not all, allow pausing for up to 30 seconds and don’t reset the timer.
You might not actively think about the pressure you’re applying when brushing. Putting too much pressure on the gums and teeth causes harm and may erode the tooth enamel. Fortunately, the best electric toothbrushes can notify you when you’re exerting excessive pressure.
Brushing modes in the best electric toothbrushes let you personalize your experience and allow you to benefit from the experience. For instance, the sensitivity setting fits someone suffering from hypersensitive gums and patients of a dental procedure.
Many electric toothbrushes have different levels of intensity. You can choose the high, medium, or low power to change the vibrating or oscillating speed (which differs from modes that change the head movement patterns).
Other hygienists appreciate varied intensities because it allows you to ease into them as you get accustomed to the usage. Various intensity levels help patients with gum recession or sensitive teeth have a slower and gentler experience while removing biofilm and plaque effectively.
Smart Toothbrush Features
High-end sonic toothbrushes connect your toothbrush to an app as it guides you through your brushing session. In addition, the apps record information such as areas you missed and how long you brushed.
These apps encourage you to practice your brushing habits and techniques in the comfort and privacy of your home.
What Toothbrush is Better Than Sonicare?
Now that you’ve decided to upgrade and wish to find the best electric toothbrush to cater to your oral needs, it’s time to decide on the best brand. Two brands reign supreme when searching for the most suitable electric toothbrush: Oral-B and Sonicare.
Sure, there are many other brands in the market, but most buyers mull between these two top-selling brands. Oral-B and Sonicare have several models under their belt, and each offers its set of advantages and disadvantages.
Considering their brush heads, brushing technology, design, and value, it’s hard for science to declare one brand better than the other. Few, if any, notice the few differences and how they affect one’s teeth’s cleanliness.
No matter the brand you choose, switching to the best electric toothbrush offers immediate improvement to your oral hygiene.
Are Sonic Toothbrushes Any Good?
Studies show that sonic toothbrushes provide better plaque removal even when held at a distance of 4mm from the tooth surface. Still, a user should brush in complete contact with the teeth. Most of today’s available sonic brush models have features that enhance your brushing experience, including bacteria-killing UV sanitizers, timers, and pressure sensors.
Another benefit a sonic brush user would enjoy is brushing longer than they ordinarily would when using a manual toothbrush.
Can an Electric Toothbrush Replace a Manual Toothbrush?
Both electric and manual toothbrushes offer an effective way of cleaning your teeth if you use the correct brushing technique and brush according to the dentist-recommended time. That said, the best electric toothbrush makes your brushing experience more effortless, which means better plaque removal.
Consult your dentist if you have questions regarding the ideal toothbrush.
Can an Electric Toothbrush Improve Your Oral Health?
Electric toothbrushes win the head-to-head battle against manual options. According to study findings, the best electric toothbrush cleans gums and teeth effectively compared to a manual toothbrush. The studies show that people who’ve embraced electric toothbrushes have better oral hygiene, minimal tooth decay, and healthier gums.
Electric toothbrushes like sonic or oscillating brush head options effectively remove plaque, which keeps gum disease and tooth decay at bay.
Do Dentists Recommend Electric Toothbrushes?
The ADA (American Dental Association) states that manual and electric toothbrushes remove bacteria and plaque from teeth as long as you use proper brushing techniques. The method used is more important than the brush used.
However, a different survey published by the Journal of the American Dental Association shows that 13,000 out of 16,000 users of electric toothbrushes experience better oral health.
How to Choose the Best Electric Toothbrush - Buyer’s Guide
Here’s what you need to consider when looking for an electric toothbrush:
First things first. What’s your electric toothbrush budget? On the lower side, you can find an electric toothbrush worth $20-$50, but it may lack certain features like a sensor, water flosser, and lithium-ion battery.
While most people may wish to spend at most $40 on a toothbrush, you can go the extra mile and spend up to $200 on those pearly whites. That amount affords you more features, especially if you want to minimize dentist visits.
What do you wish to achieve with the toothbrush? You may want one that helps you clean your teeth for the dentist-recommended two minutes. In this case, you need a toothbrush with a built-in smart timer.
Choose a Bluetooth-enabled toothbrush with an app to track your oral hygiene habits. For sensitive gums or teeth, look into the brush heads. Brands like Sonicare and Oral B have different brush heads for various needs like gum care and teeth whitening.
The electric toothbrush of choice must cater to your needs. If you wish to get a prompt for replacement brush heads, then a subscription-based electric toothbrush is your best bet. Also, don’t forget to check how long the toothbrush holds its charge.
Ease of Use
Look for an electric toothbrush that’s easy to use. While you may find a toothbrush with a timer or a tracking app to work best for you, others may feel overwhelmed by the technology.
Different toothbrushes have unique features that appeal to people differently. Some brushes are more ergonomic than others in terms of grip, weight, shape, and size. Other brushes have ridged areas on the back that make them easier to hold.
The shape of the Brush Head
Electric toothbrush head shapes have two options: with flat, oblong sonic brush heads or with round rotating brush heads. The choice between these two options comes down to personal preferences and the type of motion and brush head you find most helpful and comfortable.
Special Features and Extras
When settling on the brush features, consider the ones that’ll make you want to reach for the brush every morning or evening. That means you must be willing to spend more money on extra features like an automatic timer shut-off or a pressure sensor.
Are Sonic Toothbrushes Worth It?
Yes. Sonic toothbrushes are worth the investment. Sonic toothbrushes are worth investing in for your oral health. They stand out because they remove significantly more plaque from your teeth than other toothbrush options.
What is the Difference Between Philips Sonicare and DiamondClean?
The most significant difference between these two models is what gives the DiamondClean its ‘Smart’ name. It has Bluetooth connectivity, which the Philips Sonicare doesn’t have.
What is the Difference Between DiamondClean and ProtectiveClean?
The ProtectiveClean toothbrushes feature mid-range brushes. They’re not the most basic or cheapest options; they’re still not the most feature-rich or expensive. The DiamondClean, on the other hand, is a premium range that commands a higher ticket price courtesy of the premium prices they offer.
Is Sonicare DiamondClean Worth It?
If you’re interested in investing in a premium electric toothbrush and wish to improve your oral hygiene, the Sonicare DiamondClean range of electric toothbrushes is worth a try. The brand offers smart devices that provide in-depth teeth cleaning, and the companion app helps you see your brushing habits.
What is the Life Expectancy of a Sonicare Toothbrush?
The average lifespan of an electric toothbrush is roughly five years. Manufacturers give a two-year warranty in case the toothbrush fails sooner.
