Senyai ION-Sei Review: No toothpaste, great results

Verdict

Destructive ions? Toothpaste-less brushing? It would sound like one thing out of the again pages of a comic book e-book, however the ION-Sei’s distinctive plaque-removing, bacteria-repelling tech appears to do the trick. You’re paying for the tech although, as different fancy options like a number of modes, Bluetooth connectivity, and stress sensitivity are all absent.

Introduction

The Senyai ION-Sei is a sonic toothbrush that stands head and shoulders above the cookie-cutter competitors, due to its revolutionary use of unfavorable ions.

It blasts your tooth with unfavorable ions which not solely assist destabilise and loosen plaque, but additionally forestall enamel-eroding micro organism from attaching within the first place. Oh, and it doesn’t even require toothpaste to work its magic.

Nevertheless, with a comparatively unknown presence and a price ticket of £129.99/$149.99, it falls simply shy of impulse buy-to-try territory. So, is it price it? Listed below are my ideas.

Design and equipment

• Appears nice
• Comes with a charging dock

Accessible in a variety of enticing colors – together with a pleasant pastel Sakura Pink, Lake, Moon Gray, and Day White – this can be a toothbrush that’s dressed to impress.

And whereas design may be very a lot subjective, I’m slightly drawn to its super-glossy plastic physique, with its overly distinguished curves and futuristic Matrix-esque font. 

Around the again, you’ll discover one thing distinctive – a protracted, charcoal-grey strip that looks like a combination between plastic and graphite.

That is the electrical conduction deal with, which works in flip with a specially-designed head to assist produce these all-important ions you’ve heard a lot about.

Total, it makes a assured, visually interesting assertion, albeit one which’s a far cry away from the refined designs supplied by toothbrushes within the Sonicare or Oral-B vary. However that’s effective by me. It’s a welcome breath of recent air, particularly when sitting firmly within the equally-glossy Micro-USB charging dock (which, whereas not USB-C, remains to be higher than something that requires a selected socket). 

With two brush heads included (one onerous, one mushy) and a stable, durable-feeling construct, you gained’t really feel short-changed, though I do have one main niggle. Whereas there’s a built-in two-minute timer, the ION-Sei lacks any type of stress sensitivity indication, so that you gained’t know for those who’re brushing too onerous.

Efficiency

• Glorious brush head
• Excellent cleansing

There are two principal elements within the ION-Sei that work collectively to let it carry out its magic. The primary of those works through the use of a small replaceable battery that’s constructed into the deal with of the toothbrush (and might be changed simply by eradicating a small screw). This battery is linked to a titanium dioxide bar that runs all through the size of the toothbrush, earlier than being uncovered on the neck. It’s this uncovered part that the toothbrush head slots over.

Earlier than you sweep your tooth, you moisten this bar by operating water over the comb head. When your fingers grip the rear conductor panel, the wetness creates a closed physique circuit that flows from the toothbrush to your mouth. While you brush, a weak present is generated, and unfavorable ions flood into your mouth and throughout your tooth.

The second piece of this slightly intelligent answer brings us as soon as once more to the titanium oxide bar that lies throughout the brush head. A built-in UV LED gentle bathes the bar, producing extra unfavorable ions, that are then carried into your mouth by water and saliva. However what makes these unfavorable ions so particular?

Fairly a number of issues, it seems. For starters, unfavorable ions are extraordinarily unstable, in order that they’re determined to stay to different molecules to stabilise themselves. On this occasion, they’ve plaque firmly set of their websites, attracting them and weakening their attachment to your tooth, making for simpler plaque removing when brushing.

As well as, your tooth will likely be coated with these unfavorable ions in the course of the brushing course of, which is able to naturally repel negatively charged streptococcus mutans and porphyromonas gingivalis micro organism. The previous feeds on sugar to erode tooth enamel, whereas the latter eats away at gums, inflicting painful recession and tooth loss. It’s all very intelligent stuff, and clinically proven as well.

Does all of this fancy unfavorable ion tech work? In my case, sure. Throughout my six-week testing interval, I might visibly see a discount in plaque. Whereas I used to be additionally reviewing a number of different electrical toothbrushes on the identical time, there was an overlap interval the place the ION-Sei was my every day driver, and I can confidently say that my total dental hygiene felt higher.

Even with out toothpaste, the post-brush sensation felt refreshingly clear and nearly tingly, with a nice sensation of polished tooth. Whether or not that is all as a result of ions or the sonic head, I can’t say, nevertheless it’s a sensation that I proceed to take pleasure in to today. 

Whereas I initially ditched toothpaste and brushed purely with water as marketed, it felt incorrect to depart the toilet with none minty freshness. This brush can be utilized with toothpaste, if just for the sensation it leaves.

We additionally put my trusty dentures by means of numerous assessments, together with beetroot and spinach. The gentler nature of the ION-Sei meant that it eliminated much less bodily particles than some rivals, however this will likely be a bonus to those who hate overly-powerful electrical toothbrushes that will trigger discomfort or sensitivity. The three depth ranges might be chosen by urgent the facility button throughout use, and even probably the most {powerful} one felt pleasantly light.

The bristles on the included brush heads are additionally a number of the finest I’ve ever used. They’re extremely lengthy, and effective, offering wonderful ranges of flexibility whereas remaining agency sufficient to place in some correct work. Additionally they appear to be far more sturdy than any others I’ve examined, and I reckon they’ll final significantly longer than many different alternate options.

Battery life is formally said to be round two to 3 weeks, which is sort of a beneficiant vary. In my case, I’d say it lasted about two weeks or simply underneath. It takes fairly a very long time to cost this brush, so it’s finest topped up in a single day.
