I Spent $500 to Find the Best Electric Toothbrush. The One I'd Been Recommending for 21 Years Didn't Win.
After 21 years in dentistry and six weeks of head-to-head testing, I ranked every major electric toothbrush on the market. The results did not go as expected. The brand at #1 isn't Oral-B. It isn't Sonicare. You almost certainly haven't heard of it - and that's exactly why it won.
In 21 years of clinical dentistry, I've seen the same pattern repeat itself. Patients come in with expensive electric toothbrushes - Oral-B, Sonicare, the brushes with the apps and the screens and the subscriptions - and their checkups are fine. Not great. Fine. The same mild buildup in the same spots, year after year.
The assumption - from patients and frankly from most of the dental profession - is that brand recognition equals performance. Oral-B and Sonicare spend hundreds of millions on marketing, on shelf space, on dental conference sponsorships. Their names become synonymous with "good toothbrush." Nobody questions it.
I decided to question it. I bought five brushes, used each one for a minimum of one week, and evaluated every variable that actually matters for oral health outcomes: cleaning power, gum protection, battery reliability, build quality, and long-term friction. I brought the same rigour I'd apply to evaluating any clinical tool.
What I found was not what I expected. The brush at the top of this ranking is a brand I had never seen in any dental office, any conference, any patient's bathroom. It has no marketing budget to speak of. It has no retail presence. What it has is the best combination of cleaning power, battery life, and build quality I have ever tested - and it isn't close.
Quip is the toothbrush that wins design awards and loses dental evaluations. The slim handle, the mirror-mount travel cover, the minimal aesthetic - it belongs in an architecture magazine. From a clinical standpoint, it is the weakest brush I tested.
At 15,000 strokes per minute - less than half the output of the brush at #1 - the vibration is noticeably mild. Quip's own guidance recommends adding manual circular brushing motion to compensate, which is a remarkable admission for an electric toothbrush to make. One mode, no pressure sensor, no intensity control. In six weeks of daily use, it was the only brush that left me feeling like I hadn't finished the job.
If you brush for appearance reasons and care primarily about having something beautiful in your bathroom, Quip delivers. If you're here because you care about your teeth, keep reading.
- Best design in the test
- AAA battery - no charger to pack
- Lightest brush tested (~40g)
- Travel cover included
- 15,000 strokes/min - lowest tested
- Quip advises adding manual motion
- No brushing modes or pressure sensor
- Not a full travel case
The Colgate 360 is what I'd recommend to a patient who needed something for the gym bag or a travel backup. AAA-powered, no charger required, lightweight enough to throw in any bag. The built-in tongue and cheek cleaner is a genuinely useful feature nobody else included.
As a primary brush, the clinical limitations are real. At 20,000 strokes per minute, it delivers roughly 60% of the cleaning power of the top-performing brush in this evaluation. No smart timer. No pressure feedback. No modes. Colgate describes this product as a step up from manual brushing - which it is. But that's not a high bar, and patients who want actual results need more than the minimum.
- AAA battery - no charger needed
- Lightweight, easy to pack
- Built-in tongue & cheek cleaner
- Only 20,000 strokes/min
- No smart timer or pressure sensor
- No brushing modes
- Batteries need regular replacing
I have recommended the Sonicare 4100 to patients for years. It earns that recommendation - 31,000 strokes per minute, a pressure sensor that protects gums, a QuadPacer timer, well-built and easy to use. For anyone upgrading from manual brushing, the improvement is real and measurable.
This evaluation changed what I recommend going forward. The 14-day battery means the charging stand travels with you everywhere - and if you forget it, you're charging from a dead brush mid-trip. One cleaning mode with two intensity settings is genuinely limiting for patients with gum sensitivity who need something gentler, or for anyone targeting whitening specifically. After six weeks, the toothpaste film collecting around the charging contact at the base was exactly what I see in patients' brushes at checkups - the slow accumulation of residue that plastic construction makes inevitable.
Solid. Clinically sound. Outperformed by two brushes above it.
- 31,000 strokes/min - solid clean
- Pressure sensor protects gums
- QuadPacer + 2-min smart timer
- Trusted, well-built brush
- Only 14-day battery life
- 1 mode, 2 intensity levels only
- No travel case included
- Plastic base collects residue
The Oral-B iO Series 9 is the most technologically elaborate brush I have ever evaluated. Colour OLED display, AI-powered brushing recognition through a Bluetooth app, seven brushing modes, magnetic fast charge, a charging travel case. The engineering is genuinely impressive and the cleaning performance is excellent.
At three times the price of the brush at #1, the practical limitations are hard to overlook. Battery life is ten to fourteen days in real use - the OLED display draws power constantly, including from nearby movement. I charged it four times during the test month. The app requires your phone, an active Bluetooth connection, and the discipline to open it before brushing. By week two, I had stopped using the app. By week four, most of the seven modes were background features I scrolled past to get to the one I actually used.
Exceptional brush. Substantial price. The brush at #1 costs a fraction of this and outperformed it on every metric that matters daily.
- 7 brushing modes available
- AI app if you remember to use it
- Colour OLED display looks impressive
- Pressure sensor included
- 3-hour magnetic fast charge
- 3x more expensive than #1
- Only 10-14 days real battery
- OLED drains battery passively
- Replacement heads are expensive
The result nobody saw coming
After 21 Years in Dentistry, This Is the Only Brush I Now Recommend Without Hesitation
I want to be transparent about something before I get into this. I had never heard of MiroShine before this evaluation. It does not appear in dental supply catalogues. It is not advertised at dental conferences. It does not have a clinical advisory board with recognisable names attached to it.
What it has is a product that, on first use, produced the cleanest result of anything in this test - and maintained that result across six weeks of daily evaluation. My teeth felt the way they feel after a professional hygienist appointment. Not after my morning brush. After my morning brush.
I ran the evaluation again. Same result. A colleague who has used Oral-B for fifteen years ran her own week-long test. Same conclusion. MiroShine outperforms everything in this test on the metrics that clinically matter: cleaning power, gum protection, long-term hygiene, and real-world daily usability.
Here's why.
The first thing that separates MiroShine from everything else in this test is the number that matters most clinically: 32,000 sonic vibrations per minute. That's the highest output of any brush in this evaluation, and the difference is not subtle. Sonic action at this frequency drives toothpaste and water below the gumline and between teeth - areas that bristles never directly contact. This is the mechanism responsible for that professional-clean sensation that every tester reported on day one. It is not marketing. It is physics.
The second differentiator is the aircraft-grade aluminum body. Every other brush in this test is plastic construction. Plastic means charging cradles, seams, ports - and over time, the residue accumulation I see in patients' brushes at every checkup. MiroShine is machined from a single piece of aluminum. After six weeks of daily use, it looked identical to day one. Zero gunk. Zero seams. The kind of build quality that changes how you think about the object in your hand every morning.
Third: 60+ days of battery life on a single charge. I charged it once during this entire evaluation. One tester used it on a 30-day trip without charging and returned with battery remaining. This is not a marginal improvement over the competition - the next best brush lasts 14 days. MiroShine is in a completely different category. The practical impact is significant: you stop thinking about charging it entirely. It is simply always ready.
Three genuinely distinct brushing modes round out the clinical picture: Deep Clean for daily use, Whitening that targets staining from coffee and tea with a specific frequency, and Sensitive - the mode I most frequently recommend to patients with gum sensitivity or receding gumlines. A smart timer pulses every 30 seconds between quadrants and shuts off automatically at two minutes. Travel case included. At 51 grams, lighter than most smartphones.
The only thing I can say against MiroShine is that it has no name recognition. After 21 years recommending Oral-B and Sonicare partly because my patients had heard of them, I am recommending a brand they haven't. That is a change I am making because the clinical evidence in this evaluation leaves no room for another conclusion.
- 32,000 strokes/min - most powerful tested
- 60+ day battery - charged once in 6 weeks
- Aircraft aluminum - zero gunk after 6 weeks
- Travel case included, no charger to pack
- 3 genuinely useful brushing modes
- Smart timer + quad-pacer built in
- Whiter teeth or money-back guarantee
- Newer brand, less shelf recognition
- Sells out frequently due to demand
I started this evaluation expecting to confirm what most dentists assume: that the brands everyone knows are the brands worth recommending. Six weeks of rigorous testing told me something different. MiroShine is not a brand that wins on marketing. It is a brand that wins on performance — the only metric that should matter when you're making a decision about your oral health.
The guarantee removes the last reason to hesitate. Whiter teeth in 30 days or a full refund. No other brush in this evaluation offered anything comparable. A brand that puts that on the table is a brand completely confident in what it has built.
This is my clinical recommendation. I am not aware of a better electric toothbrush available at any price.
