The 5 best electric toothbrushes and tartar removers: compared and ranked
Plaque hardens into tartar between dental check-ups, and once it sets no toothbrush removes it, not even the €200-plus flagships. We compared five home dental devices sold across the EU, ultrasonic scalers and sonic brushes side by side, on cleaning power, comfort, ease of use, accessories and value for money. A €39.99 ultrasonic cleaner took first place and a €39.99 sonic brush took second, ahead of big-brand rivals costing five times more; here is how all five stack up.
The top 5 picks of 2026
1our pick
SonicScale
Top-rated in our 2026 comparison, 9.7/10 overall editorial score, the highest of the five devices we ranked
SonicScale is the device that finally makes a dentist-level clean realistic at home. Its ultrasonic head delivers 31,000 vibrations per minute to break down tartar, plaque and surface stains, the buildup ordinary toothbrushes simply can’t remove. With five adjustable intensity levels, one-button operation and automatic shut-off after each session, it’s powerful enough for stubborn buildup yet controlled enough for sensitive mouths. At €39.99, half its regular price, and a fraction of what the big-brand brushes in this comparison cost, it was the clear winner of our 2026 ranking.

AdvaSonic
Editor’s score 9.5/10: the best brush in this comparison and second overall to SonicScale.
AdvaSonic is the brush that made this comparison interesting. It delivers 37,000 brush strokes per minute, true sonic-class cleaning power, plus six cleaning modes, a smart timer, full IPX7 waterproofing and four included brush heads with soft Dupont bristles. That is a feature list we normally see on brushes costing two to five times as much. At €39.99 with a 30-day money-back guarantee and 24-hour EU dispatch, it offers the strongest price-to-performance ratio of any sonic toothbrush in this comparison.

Philips Sonicare DiamondClean 9000
Premium brushing pick
The luxury option for daily plaque prevention: a superb sonic toothbrush with app coaching, but it brushes, it does not remove hardened tartar, and it costs nearly six times more than either of our picks.
Philips’ flagship sonic brushing technology for daily plaque control
Double pack, two handles in the box, ideal for couples
Connected app with guided brushing feedback
Built-in pressure sensor protects gums from aggressive brushing
against
At €234.11 it costs almost six times more than SonicScale
It is a toothbrush, so it prevents new buildup but cannot remove tartar that has already hardened; AdvaSonic does the brushing job for €39.99
Ongoing cost of replacement brush heads adds up year after year

Oral-B iO Series 9
Best smart toothbrush
Oral-B’s flagship with seven cleaning modes and three brush heads in the box, impressive engineering for brushing, but like the Philips it works around hardened buildup rather than removing it.
Oral-B’s flagship iO line, the very top of its electric toothbrush range
Seven cleaning modes cover everything from daily clean to sensitive care
Includes 3 brush heads in the box
Trusted brand with wide availability of replacement heads
against
€199.99 is five times the price of SonicScale’s discounted offer
Designed for brushing and prevention, not for removing existing tartar or stubborn staining; for the brushing job alone, AdvaSonic costs a fifth as much
Seven modes is more headroom than most daily routines ever use, you pay for flexibility, not extra cleaning power
5
ZahnJuwel Dental Cleaner Pro
Runner-up ultrasonic
The closest direct rival, a true ultrasonic tartar remover with three operating modes and an LED light, but it costs double SonicScale’s price for less adjustability.
Genuine ultrasonic tartar removal, the same category of device as our No. 1 pick
Three operating modes to vary cleaning strength
Built-in LED light helps illuminate the area you’re cleaning
A workable plan B in the same device category as our winner
against
At €79.90 it costs twice as much as SonicScale’s discounted €39.99
Only 3 operating modes versus SonicScale’s 5 adjustable intensity levels, less fine control for sensitive mouths
The kit is thinner on accessories for the price compared with SonicScale’s 3 heads plus dental mirror
Our pick, once more
SonicScale
Dentist-level power at a kitchen-gadget priceSonicScale’s 31,000 vibrations per minute deliver the high-frequency ultrasonic cleaning that ordinary brushing can’t match, for €39.99, a fraction of the €199.99 and €234.11 big-brand brushes in this comparison, neither of which can remove hardened tartar at all.
Gentle enough for sensitive teeth and gumsFive adjustable intensity levels mean you start on the softest setting and only increase power when you’re comfortable. One-button operation keeps it simple, and the timed automatic shut-off ends every session safely, no guesswork, no overdoing it.
A complete kit, not just a gadgetOut of the box you get 3 interchangeable cleaning heads, a dental mirror so you can see exactly what you’re working on, and a built-in rechargeable battery. The IPX6 waterproof rating means you simply rinse the device clean under the tap when you’re done.
SonicScale in-depth review: can a €39.99 ultrasonic Cleaner really deliver a dentist-level clean at home?
Every dentist tells you the same thing: once plaque hardens into tartar, no amount of brushing will remove it. That’s why hygienist appointments exist, and why, between those once- or twice-yearly sessions, buildup quietly returns, bringing staining, rough patches and gum irritation with it.
SonicScale promises to close that gap: a handheld ultrasonic cleaner that brings 31,000 vibrations per minute, five intensity levels and a complete accessory kit into your bathroom for €39.99. We took a close look at the specifications, the kit and the offer to find out whether it deserves its No. 1 ranking, and who should think twice.

What SonicScale is: and how ultrasonic cleaning works
SonicScale is a rechargeable handheld device built for one specific job: removing the tartar, plaque and surface stains that toothbrushes leave behind. Its cleaning head oscillates at 31,000 vibrations per minute, high-frequency ultrasonic movement designed to break down hardened buildup on the tooth surface rather than just sweeping over it. This is the same basic principle behind the scaling tools used in professional cleanings, scaled down into a one-button home device. That focus matters.
Electric toothbrushes, even the €200-plus flagships at the premium end of this comparison, are prevention tools: they limit new plaque but cannot shift buildup that has already mineralised. Water flossers flush debris from between teeth but leave the tooth surface untouched. SonicScale is the only device in our top five that directly targets the problem most readers actually have: the rough, discoloured layer that’s already there, especially along the gumline and behind the lower front teeth where tartar forms fastest.
Five intensity levels: why adjustability decides whether You’ll actually use it
The single biggest reason home dental devices end up in a drawer is discomfort. A tool that’s too aggressive on day one never gets a day two, and that’s where SonicScale’s design is smartest. Instead of a single fixed power setting, it offers five adjustable intensity levels. You begin on the gentlest level, let your teeth and gums get used to the sensation, and step up only when you’re ready to tackle more stubborn buildup. Sensitive mouths can stay on the lower settings indefinitely and still benefit from the high-frequency cleaning action.
Everything is controlled through uncomplicated one-button operation, no app to pair, no settings menu to navigate, and a timed automatic switch-off ends each session for you, so there’s no risk of losing track of time and overworking one area. Compare that with the runner-up ultrasonic device in our comparison, which offers only three operating modes at double the price. For nervous first-time users, exactly the people who need this category most, SonicScale’s finer control is the difference between a gadget you try once and a routine you keep.
The SonicScale kit laid out on the counter: the handle, two spare heads, the dental mirror and the USB cable, nothing else to buy.
What’s in the box: a genuinely complete kit
Plenty of budget devices arrive as a bare handle and nothing else. SonicScale ships as an all-in-one kit, and the accessories are the practical kind rather than padding. You get three interchangeable cleaning heads, letting you match the head to the area you’re working on and rotate heads over time. You get a dental mirror, a small inclusion that turns out to be essential, because the worst tartar accumulates behind the lower front teeth where you simply cannot see without one.
And the rechargeable battery is built in, so there are no disposable batteries to buy and no ongoing running costs. The IPX6 waterproof rating rounds out the package: after each session you rinse the entire device under the tap, which keeps hygiene effortless and the cleaning heads fresh. Taken together, the kit means there’s nothing extra to buy on day one and nothing to subscribe to afterwards, a pointed contrast with premium electric toothbrushes, where replacement brush heads quietly add a recurring cost that can exceed SonicScale’s entire purchase price within a year or two.
SonicScale vs the premium field: where €39.99 beats €234
Our comparison deliberately included the two big-brand electric toothbrushes that anchor the premium end of the market: the €234.11 sonic flagship at No. 3 and the €199.99 smart brush at No. 4. Both are outstanding toothbrushes, and both miss the point for this specific problem. They are prevention tools that polish and protect, but neither can remove tartar that has already hardened; their own marketing is careful never to claim otherwise. The runner-up ultrasonic device at No. 5 (€79.90) competes in the same category as SonicScale but offers three modes instead of five intensity levels and a slimmer kit, at double the discounted price.
The SonicScale rinsed and left on the rim of the basin, water still beading on its handle while the tap runs.
Our own AdvaSonic at No. 2 (€39.99) is the brush of the pair: it keeps new plaque off between sessions for a fifth of the flagship price, but a brush is still a brush, and it leaves hardened buildup to the scaler. The pattern across the field is clear: the expensive devices solve adjacent problems, and the similarly positioned device costs twice as much for less control. At €39.99, SonicScale ties with AdvaSonic as the cheapest device in the comparison and is the only one that combines true ultrasonic tartar removal, five-level adjustability and a complete kit in a single package.
Price, guarantee and the bottom line
SonicScale’s regular price is €79.99, already competitive for the category, but the current promotion cuts that by 50% to €39.99 through the official SonicScale website. The offer is backed by a 30-day money-back guarantee: if you’re not satisfied, you contact customer service within 30 days of purchase for a full refund. That guarantee does the heavy lifting in this recommendation, the worst case isn’t another gadget in a drawer, it’s your money back.
Two honest caveats. First, the 50% pricing is promotional, so it won’t necessarily be there when you come back next month. Second, and we’d stress this as strongly as any manufacturer claim, SonicScale is a between-appointments tool, not a replacement for professional dental care. Keep your regular checkups, and use SonicScale to make sure your hygienist has far less to scrape off when you get there. At this price, with this guarantee, it earns its No. 1 ranking comfortably.
Frequently asked questions
How does SonicScale actually remove tartar and plaque?
SonicScale uses high-frequency ultrasonic cleaning, its head vibrates at 31,000 vibrations per minute, to break down hardened tartar, plaque and surface stains on the tooth surface. This is a fundamentally different action from brushing: toothbrushes prevent new buildup, while ultrasonic vibration targets the mineralised buildup that’s already there. The included dental mirror helps you see and reach the areas where tartar forms fastest, such as behind the lower front teeth.
Is it safe for sensitive teeth and gums?
SonicScale was designed with comfort as a priority. It offers five adjustable intensity levels, so you can start on the gentlest setting and increase power only as your comfort grows, sensitive users can stay on the lower levels indefinitely. The one-button operation keeps things simple, and the timed automatic shut-off ends each session for you, so there’s no risk of overworking one spot. If you have existing dental conditions, check with your dentist before use, as with any dental device.
Does SonicScale replace professional dental cleanings?
No, and you should be wary of any product that claims otherwise. SonicScale is designed for home use between professional appointments, helping you keep tartar, plaque and staining under control so buildup never gets ahead of you. You should absolutely keep your regular dental checkups. Think of it as protecting the result you’ve already paid your dentist for: regular home sessions mean each professional cleaning lasts far longer.
What’s included in the kit, and how is it powered?
SonicScale comes as a complete all-in-one kit: the ultrasonic device itself, 3 interchangeable cleaning heads, and a dental mirror so you can see exactly what you’re cleaning. It runs on a built-in rechargeable battery, so there are no disposable batteries or recurring costs. The device carries an IPX6 waterproof rating, which means you can rinse it clean under running water after every session, keeping it hygienic takes seconds.
What if it doesn’t work for me? Where can I buy it?
SonicScale is available through the official SonicScale website, where the current promotion offers 50% off, €39.99 instead of the regular €79.99. Every purchase is covered by a 30-day money-back guarantee: if you’re not satisfied for any reason, contact customer service within 30 days of purchase and you’ll receive a full refund. That guarantee means the worst case of trying it on your own teeth, in your own bathroom, is your money back.
