Electric toothbrushes have revolutionized oral hygiene, offering superior cleaning power compared to manual brushes. For those seeking a brighter, whiter smile, certain models stand out for their whitening capabilities.
Why Choose an Electric Toothbrush for Whitening?
Along with a good toothpaste and whitening strips or an LED whitening kit, an electric toothbrush can maintain those pearly whites safely and easily — especially those spots you simply can’t reach with your manual toothbrush. “I recommend using an electric toothbrush over a manual toothbrush because of its superior ability to clean hard-to-reach spots. Electric toothbrushes are much like the professional instruments that dentists use, both in shape and the way the bristles vibrate or rotate.”—Dr. Bill Busch of NKC Dental, team dentist for the Kansas City Chiefs and Kansas City Current.
Buying Guide: What to Look for in a Whitening Electric Toothbrush
We asked Dr Praveen Sharma – a specialist in restorative dentistry and scientific advisor to the British Dental Association – about which features are most important. The expert recommends a rechargeable electric toothbrush with a timer, medium-stiffness bristles and a small brush head. “Don’t let the cost of really expensive brushes put you off,” says Dr Sharma. “Even the most reasonably priced ones can have the features listed above. Other features are in the category of ‘nice to have but not essential’”. “Whether you use a manual or an electric toothbrush, the most effective way to clean teeth is to use the correct technique, brushing all surfaces of the teeth for at least two minutes, with a fluoride toothpaste,” says Dr Sharma. “Your dentist or dental hygienist will be happy to advise on individualised oral hygiene regime/aids, including tooth-brushing training.”
- Whitening Modes: Most toothbrushes have one mode, but some offer multiple modes with different intensities. These modes are labeled “whitening” or “gum health” but are just marketing terms. The speed of vibrations differentiates these modes.
- Timer: All the electric toothbrushes in our ratings have this feature. It’s a crucial one, because plenty of people tend to brush for less than the 2 minutes per brushing session that the American Dental Association recommends. In many cases, electric toothbrush timers work by vibrating every 30 seconds.
- Pressure Sensor: This feature is another favorite of many dentists because you can cause a lot of problems for yourself when you press too hard with your toothbrush. Excessive pressure can wear down your enamel, the hard outermost layer of your teeth, which can cause your teeth to become more sensitive.
- Brush Head Design: The smaller, round rotary heads let us navigate around our mouths to truly clean the entire surface of our teeth. On the other hand, Mark S. Wolff, DDS, a dean and professor at the University of Pennsylvania explains that, “The little round heads take a little bit more skill to go over every surface of every tooth.”
- Battery Life: Some can keep going for weeks, while others need recharging on a weekly basis. We check how long the battery lasts, how long it takes to recharge and its endurance.
Top Electric Toothbrushes for Whitening Teeth
1. Oral-B iO Series 9
The Oral-B iO Series 9 is by far the best smart toothbrush we tested, with an app that offered consistently accurate and useful feedback. The brush itself — a sleek metal unit with a colorful LCD display — offers seven different modes, the most out of any toothbrush we tested, along with the full suite of standard features, such as an easy-to-view pressure sensor indicator and two-minute timer (with 30-second pulsing quadrant reminders). The seven modes include daily clean, intense clean, whitening, gum care, sensitive, super sensitive and tongue clean.
Pros:
- Seven cleaning modes, including a dedicated whitening mode
- Smart pressure sensor with color-coded lights

2. Philips Sonicare ProtectiveClean 6100
The ProtectiveClean 6100 toothbrush stands as a testament to Sonicare’s excellence, surpassing even the fanciest Sonicares with its multiple settings—clean, whiten, and gum—three intensity levels, and superior performance. It’s very easy to set up this electric toothbrush — just hit two buttons: one to turn it on and the other to choose from clean, whiten, and gum (for focused gum health).
Pros:
- Three modes (clean, whiten, gum) with three intensity levels

3. Aquasonic Black Series Ultra Whitening Toothbrush
The Aquasonic Black Ultra Whitening Toothbrush has an incredible whitening feature that brightened our teeth in just a few uses during testing. It effectively removed surface stains while also giving us a deep clean that left our mouths feeling fresh. The compact head proved perfect for smaller mouths. We also love that the brush head hit hard-to-reach areas with ease without triggering a gag reflex.
Pros:
- ADA-accepted for efficacy
- 40,000 VPM motor for powerful cleaning
- Includes eight brush heads and a travel case
- Budget-friendly price

4. Snow Advanced LED Whitening Toothbrush
Snow’s sonic toothbrushes are super comfortable to use; I found myself leaning toward sensitive options with brands like Moon, but I have been plenty happy with the standard setting for Snow’s LED toothbrush. There are settings for whitening and polishing too. The brush also has blue-light technology built into it to help whiten your teeth even on the non-whitening settings, and I do think mine look a touch brighter after weeks of use—you won’t get the same effect as a true whitening product if you’re looking for serious brightness, but I like that this can help me try to keep the tea stains away.
Pros:
- Blue-light technology for enhanced whitening
- Comfortable for sensitive teeth
- Includes additional accessories (tongue scraper, face brush)
- Two-year warranty
Cons:
- Premium price
- Whitening effect less dramatic than professional treatments

In-Depth Analysis and User Experiences
The Oral-B iO Series 9 stands out for its advanced technology. I upgraded from my Oral-B Pro 1000 to its newer iO Series toothbrush about a year ago. Off the bat, it’s a much sleeker model, with its OLED display on the brush handle and magnetic charging stand, but its souped-up features stand out most. Like the Pro 1000, it combines rotating, oscillating, and sonic technology, plus a two-minute quadrant timer to make sure you’re brushing the right amount of time. Rather than one mode, it comes with seven: daily clean, gum care, sensitive, super-sensitive, whitening, intense, and tongue clean. I personally use the two-minute daily-clean setting twice a day, which leaves my teeth feeling squeaky clean.
The Philips Sonicare ProtectiveClean 6100 impressed testers with its simplicity and effectiveness. 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!” However, some users noted its high-pitched noise as a minor drawback.
The Aquasonic Black Series offers exceptional value. Our teeth felt wonderfully clean, so we converted to using electric toothbrushes. Despite the relatively high cost, the investment seemed worthwhile considering its daily use and impact on dental health. Its compact head was particularly praised for smaller mouths.
The Snow Advanced LED toothbrush adds a unique whitening angle with its blue-light technology. While many toothbrushes (including this one) have a built-in whitening setting that adds time or alternates speeds to remove surface stains, the Whites Beaconsfield sonic LED toothbrush – with its terrifying picture of a toothy strawberry on the box – goes the extra mile by including blue light whitening technology. The company says this can whiten teeth by an average of 2.5 shades in three days. A week’s use did indeed appear to make my teeth appear slightly lighter in before-and-after shots, although you shouldn’t expect miracles.
Expert Insights
Dentist Sharon Huang of Les Belles NYC explains that sonic toothbrushes use a sonic wave to dislodge debris all on its own, which she likes because it requires less force to get the job done. “The rotation mechanism, you actually have to touch the tooth and it’s rotating and it’s helping you clean it,” she says. “The sonic toothbrush has a sonic wave. So if you’re in the vicinity, and you’re not even touching your tooth, it’s supposed to be dislodging bacteria.” The sweet spot is a toothbrush that does it all, but orthodontist Janet Stoess-Allen, says that because teeth are curved, “rotating heads are more effective in getting to all sides of them.”
American Dental Association suggests that electric toothbrushes with timers and pressure sensors can significantly improve brushing habits, especially for those aiming to whiten teeth safely.
Frequently Asked Questions (FAQ)
1. Do electric toothbrushes really whiten teeth?
While electric toothbrushes with whitening modes can remove surface stains effectively, they won’t change the intrinsic color of your teeth. Combining them with whitening toothpaste or strips can enhance results. “However, he has not found any differences in the color of the teeth of patients who have used the whitening modes on their electric toothbrushes,” says Dr. Evan Novick.
2. How often should I replace the brush head?
Experts recommend changing your toothbrush head every three months. Many models, like the Oral-B iO, have bristles that fade to indicate replacement time.
3. Are whitening toothbrushes safe for sensitive teeth?
Yes, if they have sensitive modes or pressure sensors. The Philips Sonicare ProtectiveClean 6100 and Snow Advanced LED are great for sensitive teeth due to their gentle settings.
4. Can kids use these toothbrushes?
Generally, you’ll want to wait to introduce kids to electric toothbrushes since toddlers’ gums may be too tender for bristles, Rabinovich tells us. Check for kid-specific models from brands like Oral-B.
5. Do I still need to floss?
Sorry, but using an electric toothbrush will not get you out of a flossing routine. “Nothing — I repeat — nothing replaces flossing,” says Dr. Busch. “Only floss can get in the deep crevices of gums and in between your teeth.”

Choosing the best electric toothbrush for whitening teeth depends on your budget, preferences, and oral health needs. The Oral-B iO Series 9 offers cutting-edge technology for tech-savvy users, while the Philips Sonicare ProtectiveClean 6100 balances performance and affordability. For budget-conscious buyers, the Aquasonic Black Series delivers impressive whitening at a fraction of the cost. The Snow Advanced LED toothbrush adds a unique whitening boost with its blue-light technology. Pair your chosen toothbrush with proper brushing technique and fluoride toothpaste for a dazzling smile.
