All 8 electric toothbrushes, ranked
Ranked by test scores, minus how common and serious the complaints are. How we rank
#1
Oral-B
Oral-B Pro 1000 Rechargeable Electric Toothbrush
$$OscillatingScore 3.7/5
6%
of Amazon ratings are 1–2 stars
(checked 2026-10-10)Wirecutter's long-running top pick, with cheap, widely available heads. It is louder than sonic brushes, and its pressure alert is easy to miss. Owners also report units that stop holding a charge.
Top complaints
- Stops holding a charge or dies earlyMentioned often
Amazon's review summary says the battery gets mixed feedback, with some owners saying it stops holding a charge and several saying it stopped working within two weeks. Walmart's lowest-rated reviews describe units that stopped charging after about two months, chargers that didn't work, and a motor that slowed down after a month.
- LoudVery common
Wirecutter calls Oral-B brushes like the Pro 1000 louder and more sonically grating than comparable Sonicare models. Electric Teeth measured 73 dB, versus 60 dB for the Sonicare 4100. Amazon's summary says customers find it somewhat loud.
- Weak pressure alert, no auto shut-off, vague battery lightMentioned often
Wirecutter's testers had to press harder than expected to trigger the pressure sensor. The brush also keeps running after two minutes until you switch it off, and the battery light only shows full or low. Electric Teeth found the pressure alert neither visible nor audible and easy to miss.
- Button and slippery handleMentioned often
Amazon's summary says some customers struggle with the on/off button. Walmart low-star reviewers say the button is hard to use and the smooth plastic body gets slippery when wet.
What owners love
- Cheapest heads among the big brands
Wirecutter puts standard Oral-B heads at about $5 each in bulk and estimates a three-year cost of about $98, versus about $170 for the Sonicare 4100.
- Effective, with a quadrant timer
Amazon shoppers find it effective and like the 2-minute timer that pulses every 30 seconds. Wirecutter calls the motor plenty powerful.
- Proven in long-term testing
Wirecutter's test unit survived floor-drop and water-dunk tests and seven years of twice-daily use. It has a two-year warranty.
Skip it if…- Brush noise bothers you
- You want a clear, visible pressure warning
- You want two or more weeks per charge
Good for- Lowest long-term cost among the big brands
- People who prefer a round oscillating head
- A simple one-button brush

It has a sensitive mode, but the pressure alert takes a hard press to trigger (Wirecutter) and is easy to miss (Electric Teeth). - Battery2.5

About $5 per head in bulk, with eight compatible styles (Wirecutter). - Ease of use3.5
Why 3.5?
Simple one-button design (Wirecutter), but there's no auto shut-off and some owners dislike the button and slick handle (Amazon, Walmart). - Durability3.5
Why 3.5?
Wirecutter's unit lasted seven years, but durability is a concern in Amazon's summary and Walmart owners report early charging failures.
What experts say
- Wirecutter (NYT): Top pick for nearly a decade (updated 2026-09-01) for its timer, affordable heads and durability; the flaws are noise, manual shut-off, a vague battery light and a pressure sensor that takes a hard press to trigger.
- Electric Teeth: 4.5/5. Its cons are no visible pressure sensor and about 10 days of battery; recharging takes up to 12 hours.
#2
AquaSonic
AquaSonic Black Series Ultra Whitening Toothbrush
$SonicScore 3.7/5
6%
of Amazon ratings are 1–2 stars
(checked 2026-10-10)Amazon's most-rated electric toothbrush comes with 8 heads, a travel case and a month-plus battery. Testers found it feels cheaper and less gentle than Sonicare or Oral-B, and it has no pressure sensor.
Top complaints
- Intense vibration, not very gentleVery common
Electric Teeth found it less gentle than Sonicare or Oral-B, said even the soft mode didn't feel very soft, and described the bristles as stiff. Amazon's summary calls the vibration level mixed and pretty intense. Some 1-star Walmart reviews say the vibration was hard to tolerate.
- No pressure sensorVery common
CNN Underscored says the missing pressure sensor is the main reason it didn't earn a top spot. Electric Teeth also lists it as a con.
- Cheaper build; some die around 6 monthsMentioned often
Electric Teeth says it feels cheaper than premium rivals (the chrome rings are plastic) and notes some reports of breakage; the warranty is 1 year. Amazon's summary says durability is mixed, with some owners saying it stopped working after 6 months. Walmart low-star reviews mention dead chargers and heads that don't stay on.
- Small headsOccasional
CNN Underscored notes the included heads are on the smaller side, and a Walmart 1-star reviewer compared the head to a toddler's.
What owners love
- Lots in the box for little money
CNN Underscored notes it includes a travel case and enough heads to last two years. Value for money is a top Amazon praise.
- Long battery
Electric Teeth got 39 days (78 sessions) on a charge, beating the claimed four weeks; Amazon owners praise long-lasting charges.
- Cleans well
Electric Teeth's plaque-disclosing tests raised no concerns, and Amazon owners say teeth feel squeaky clean.
Skip it if…- You have sensitive gums or teeth
- You tend to brush too hard and want a pressure sensor
- You want premium build quality
Good for- Tight budgets (8 heads in the box)
- Travel (case plus a long battery)
- People who like a strong buzz

Why 2.5?
Cheaper materials and a 1-year warranty (Electric Teeth); Amazon's durability feedback is mixed, with failures around 6 months.
What experts say
- CNN Underscored: Tested but not picked: a great affordable option with four modes and a travel case, held back mainly by the lack of a pressure sensor.
- Electric Teeth: 4.4/5 and excellent budget value. The cons are no pressure sensor and cheap materials, and it is less gentle than Sonicare or Oral-B (65 dB).
#3
Philips Sonicare
Philips Sonicare 4100 Rechargeable Electric Toothbrush
$SonicScore 3.7/5
10%
of Amazon ratings are 1–2 stars
(checked 2026-10-10)A quiet, simple sonic brush that two major testers rank first or second, but its heads cost about twice as much as Oral-B's. Owners also report units that stop charging or die within a year.
Top complaints
- Heads cost about twice as much as Oral-B'sVery common
Wirecutter says Sonicare heads can cost more than double Oral-B's and estimates a three-year cost of about $170 versus about $98 for the Pro 1000. Electric Teeth puts heads at about $10 each.
- Stops charging or dies within a yearMentioned often
Amazon's review summary says multiple customers report it stopped working in less than a year, and some say it stops charging or feels weak.
- USB-only chargerMentioned often
Since October 2021 the charger has had only a USB plug with no wall adapter (Wirecutter; Philips will send one free on request). Amazon's summary calls charging problematic because only a USB cord is included. Electric Teeth says a full charge can take up to 24 hours.
- Vibration felt through the whole brushMentioned often
Wirecutter says the vibrations can be felt throughout the brush even on low, and the hard plastic back of the head can knock against opposing teeth. Electric Teeth notes there is no light to show which intensity is selected.
What owners love
- Quiet
Wirecutter measured about 30 dB on high, quieter than the Pro 1000; Electric Teeth measured 60 dB versus 73 dB for the Pro 1000.
- Long battery life
Wirecutter averaged 16 days of twice-daily use. Electric Teeth got 17 days on high intensity and about 41 on low.
- Pressure sensor and gentle start
CNN Underscored found the pressure sensor works as expected and liked the EasyStart mode, which ramps up power over the first 14 uses. It found the low setting good for gums.
Skip it if…- You want the cheapest heads
- You dislike vibration felt through the handle
- You want a wall plug in the box
Good for- A quiet brush
- Smaller mouths (narrower heads)
- Newcomers who want a pressure sensor and a gentle start-up mode

One button with auto shut-off (Wirecutter), but there's no intensity indicator and the charger is USB-only. - Durability3.0
Why 3.0?
2-year warranty, but Amazon's summary flags units failing in under a year, and Electric Teeth says it can't be repaired at home.
What experts say
- CNN Underscored: Best electric toothbrush overall for its combination of usability, performance and value, with a pressure sensor, 14-day battery and two-year warranty.
- Wirecutter (NYT): Runner-up: quieter, with longer battery life and auto shut-off, but its heads cost twice as much, vibrations can feel uncomfortable and the charger is USB-only.
- Electric Teeth: 4.9/5. Its cons are no indicator for the selected intensity and a motor tuned differently from premium Sonicare models.

Oral-B
Oral-B iO Series 9 Rechargeable Electric Toothbrush
$$$OscillatingScore 3.8/5
6%
of Amazon ratings are 1–2 stars
(checked 2026-10-10)This current 'iO9 Limited' Amazon listing has only 570 ratings (5% 1-star, 1% 2-star).CNN's favorite smart brush, with seven modes, a color screen and app coaching. It costs about $300, uses pricier iO-only heads, and testers disagree on how accurate its tracking is. Its battery is shorter than many cheaper brushes.
Top complaints
- Very expensiveVery common
CNN Underscored calls the roughly $330 list price a tough sell even on discount. Electric Teeth puts the US suggested price at $299.99. Amazon's summary says value for money is mixed, with some owners finding it overpriced.
- iO-only heads and a mold-prone gapVery common
Electric Teeth puts iO heads at about $8, roughly twice the price of standard Oral-B heads, and says mold can build up in the gap around the magnetic head mount. Wirecutter notes some customer reviewers clean that junction daily.
- Tracking accuracy disputedMentioned often
Electric Teeth found position tracking inconsistent, sometimes logging the wrong zone, and worse for left-handed users. CNN Underscored, by contrast, found the app accurate every time it tested it. Amazon's summary calls tracking mixed.
- About 12 days per chargeMentioned often
Electric Teeth usually got about 12 days against a 14-day claim, though the charger refills it in about 3 hours. Amazon's summary says some owners report it doesn't hold a charge.
What owners love
- Useful real-time feedback
CNN Underscored says the feedback after each session made it easy to improve and that the app caught deliberate mistakes every time.
- Seven modes, softer iO motor
CNN lists seven modes, including sensitive and super sensitive. Electric Teeth says the iO motor is much softer than older Oral-B models and still cleans as well.
- Holds up over years
CNN's tester has used it for years and says it still functions like new.
Skip it if…- You won't use the app
- You're on a budget
- You're left-handed and want reliable position tracking
Good for- People who want app coaching and data

Why 4.0?
Still like new after years for CNN's tester; user-replaceable battery and very durable case (Electric Teeth); 2-year warranty.
What experts say
- CNN Underscored: Best smart electric toothbrush, with accurate coaching and seven modes; the main drawback is the steep price.
- Electric Teeth: 5/5 (reviewed 2026-10-05), but pricey: iO-only heads, non-essential Bluetooth that adds cost, inconsistent tracking, about 12 days of battery, and 72 dB.
- Wirecutter (NYT): Says iO brushes run $50-380 and calls the iO Series 6 the best value in the line; it finds smart brushes generally disappointing because their apps tend to be buggy.
#5
Oral-B
Oral-B iO Series 3 Rechargeable Electric Toothbrush
$$OscillatingScore 3.6/5
13%
of Amazon ratings are 1–2 stars
(checked 2026-10-10)The cheapest way into Oral-B's quieter, gentler iO motor, with a visible pressure light. It locks you into pricier iO-only heads, and it has the highest share of 1-star Amazon ratings among the big-brand picks here.
Top complaints
- Stops working after about 6 monthsVery common
Amazon's review summary says many customers report the brush stopping after 6 months of use, with battery life and durability both getting mixed reviews. 10% of Amazon ratings are 1-star.
- iO-only heads cost moreVery common
Standard Oral-B heads don't fit iO models. Wirecutter found iO heads at about $7 each in an eight-pack and up to $15 each, more than double standard heads. Electric Teeth lists this as a con.
- Unlabeled modes, mold-prone gap, slow chargingMentioned often
Electric Teeth notes there are no mode labels or icons, a full charge takes up to 16 hours, and the gap at the head and neck can trap bacteria and grow mold. Wirecutter says some customer reviewers clean that iO junction daily.
What owners love
- Quieter and gentler than older Oral-Bs
Electric Teeth measured a maximum of 64 dB, versus 73 dB for the Pro 1000, and found the iO action gentler and less aggressive.
- Easy-to-read pressure light
Amazon shoppers like its ease of use, and one notes that the pressure light makes good technique simple. Electric Teeth describes white, green and red light states.
- Cleans like a dentist visit
Amazon shoppers call it the best in its class for cleaning, and Electric Teeth says it cleans well.
Skip it if…- You want the cheapest heads
- You're bothered by gunk building up where the head meets the handle

- Wirecutter (NYT): Covers the iO line as a group: it calls the iO Series 6 the best upgrade but notes iO heads cost more than double standard heads and some testers found iO heads more drooly.

Philips Sonicare DiamondClean Smart 9300
$$$SonicScore 3.6/5

of Amazon ratings are 1–2 stars
(checked 2026-10-10)Based on 1,192 ratings for the HX9903/45 listing (12% 1-star, 2% 2-star).Sonicare's app-connected premium brush cleans well and has a pressure sensor and a glass charging cup. It costs four times as much as the 4100, its heads are pricey, and 14% of Amazon ratings are 1-2 stars, mostly citing breakage and charging.
Top complaints
- Breaks or stops chargingVery common
Amazon's summary says durability and battery feedback are mixed: some units last up to 10 years but others break within months, and some don't charge at all. 12% of ratings are 1-star.
- High price and pricey headsVery common
Electric Teeth lists the high price as a con. It found DiamondClean heads at $30 for a 2-pack or $50 for a 4-pack. Amazon's summary says some owners call it a bad investment.
- NoiseMentioned often
Amazon's summary says some customers find the noise too loud to tolerate for long. Electric Teeth measured 71 dB but still found it quieter than Oral-B models.
- No charging travel case, slow charge, one user per handleMentioned often
Electric Teeth says the 9300, unlike the 9500 and 9700, can't charge inside its travel case. A full charge takes at least 24 hours, and the handle logs data for only one user.
What owners love
- Top-tier clean
Amazon shoppers praise its cleaning and whitening. Wirecutter found it gives nearly the same experience as Sonicare's $400 9900 Prestige.
- Pressure sensor, gentler than Oral-B
Wirecutter notes the lighted pressure sensor. Electric Teeth says the sensor slows the motor and finds Sonicare's clean gentler than Oral-B's.
- Long battery
Electric Teeth expects 14-25 days in normal use; its DiamondClean Smart test unit lasted about 25 days on high.
Skip it if…- You won't use the app

- Electric Teeth: 5/5 for the DiamondClean Smart line (tested on the 9500). The cons are a high price and no phone stand, and the 9300 lacks the charging travel case, making the 9500 worth the extra spend.

Waterpik Sonic-Fusion 2.0 Flossing Toothbrush
$$$SonicScore 2.7/5
9%
of Amazon ratings are 1–2 stars
(checked 2026-10-10)This Amazon listing is titled 'Sonic-Fusion ... SF-04' without '2.0'. Electric Teeth calls the SF-04 the Professional version of the 2.0.A popular two-in-one sonic brush and water flosser with a 3-year warranty, but expert testers prefer separate devices. Its heads cost over $12 each, the brush battery is short, and owners report the flosser or whole unit failing.
Top complaints
- Unit or flosser stops workingVery common
Amazon's summary flags durability, citing units breaking after 3 months, and says flossing performance is mixed. Walmart 1-star reviews describe units dead on arrival, flossers that quit within weeks, and a casing that fell apart.
- Most expensive heads hereVery common
Wirecutter says replacement heads cost over $12 each, among the most expensive it considered. Electric Teeth found them at $25 for two.
- Clunky, corded and not portableMentioned often
Electric Teeth calls it conceptually great but poorly executed: the handle is chunky and heavy and the flosser base isn't portable. Walmart reviewers dislike the cord running to the sink and call it clunky and loud.
- Short brush batteryMentioned often
Electric Teeth measured about 11 days on the higher speed, short of Waterpik's roughly 2-week claim, and lists poor battery life as a con.
What owners love
- Feels very clean
Amazon shoppers call it easy to use and say it leaves teeth feeling super clean.
- Long warranty, ADA accepted
Electric Teeth notes a 3-year warranty and ADA acceptance; Waterpik's replies to Walmart reviews cite the same three-year warranty.
- Adjustable flossing pressure
Electric Teeth notes 10 pressure settings and a timer and pacer.

36%
of Amazon ratings are 1–2 stars
(checked 2026-10-10)Based on only 130 Amazon ratings (27% 1-star, 9% 2-star). Walmart's 'Ultra Smart Sonic' listing (559 ratings) shows 12% at 1-2 stars.A stylish, long-lasting sonic brush that Tom's Guide picks for whitening. Its pods are pricey, its pressure sensor often trips at a light touch, and owners report breakage and charging trouble. A third of its Amazon ratings are 1-2 stars.
Top complaints
- Breaks or stops chargingVery common
Amazon's summary says build quality and durability are mixed, with some units breaking within a week, and calls battery life problematic with multiple charging complaints. Walmart 1-star reviews describe a head that snapped after 3 weeks, a handle band coming loose, pods falling off at about 10 months, and no charging light.
- Over-eager pressure sensorMentioned often
Several Walmart 1-star reviewers say the brush pulses, beeps or stops even when barely touching their teeth. In a reply, quip says the sensor can be toggled in the app and that users shouldn't scrub.
- Expensive brush podsVery common
Tom's Guide lists head cost as the main drawback: $12 each, or $8 on subscription. Wirecutter gives the same prices and says swapping the pod takes more dexterity than a normal head.
- Touch slider changes power by accidentMentioned often
Wirecutter found the haptic slider easy to bump while brushing, and the battery indicator sometimes failed to warn before the battery died.
What owners love
- Visibly whiter teeth
Tom's Guide was skeptical of quip's whitening claim but says the results were undeniable.
- 30-day battery and good accessories
Tom's Guide cites up to 30 days per charge plus a stand and travel case.

What experts say
- Tom's Guide: Best for whitening (updated 2026-05-29). It is user friendly, but the app's smart features add little, some users may feel sensitivity at high intensity, and heads are expensive.
- Wirecutter (NYT): Not picked: thoughtful design and an effective pressure sensor, but the slider is easy to bump by accident, the battery warnings are unreliable and pod swaps are fiddly.
- Electric Teeth: Rates the Ultra the best quip (4.8/5), at about $100 direct; the warranty is 1 year, or as long as you keep a subscription.
