Fluoride vs Nano-HAp
What is the difference between Fluoride and Nano-HAp?
Fluoride and Nano-Hydroxyapatite (Nano-HAp) both enhance dental health effectively. Fluoride is renowned for its
ability to strengthen tooth enamel and prevent cavities. Nano-HAp offers a similar benefit as a fluoride-free
alternative, perfect for those who prefer it, and is especially safe for children who might swallow toothpaste.
Dentists everywhere say these don't work! So, what makes autobrush different?
It’s tricky. Most dentists are familiar with u-shaped brushes as a category, rather than our exact model. We are the only u-shaped toothbrush with a patented nylon brush head (as opposed to silicone) with clinical studies to back our claims. In our study with Salus research, they found autobrush removed plaque 27X better than a traditional brush.
Why are other "u-shaped" toothbrushes cheaper on Amazon?
Cheaper? Yep, but you get what you pay for. Many of those lower-priced “u-shaped” toothbrushes on Amazon feature silicone bristles, which is proven to be less effective than not brushing at all. In contrast, autobrush uses patented nylon bristles—clinically proven (in three separate clinicals) to clean your teeth 27x better and reduce gingivitis up to 45%. It might cost a bit more, but it’s an investment in your future oral health.

How effective is autobrush on the gum line?

Are there clinical studies to prove autobrush works?
We have 3 clinical studies (and more to come!). We are the only u-shaped toothbrush on the market shown to brush even better than traditional manual toothbrushes.

Explanation
Why parents love Autobrush
★★★★★
"My daughter is obsessed with her unicorn toothbrush. She has brushed her teeth 6x in the past 15 minutes. She loves the toothpaste too (bubblegum) and it smelled great."
"Made my kids so excited for teeth brushing!! I bought a cheaper version and the bristles are not nearly as dense and it doesn’t really clean. I love the lights and music, and it comes with stickers for kids to track their brushing. Best of all it made my 5 year old brush his teeth on his own instead of asking us to do it. Win win win."
"We have tried other brushes and end up just doing it ourselves after fighting our five year old for an hour. After much debating we finally ended up spending what we had wasted on the dozens of others beforehand on the Autobrush but after the extensive amount of research that I have poured into this brush and hundreds of others, the many patents and much more make the high price point extremely logical... She is so very excited about her unicorn autobrush!"
"My 5-year-old and 2-year-old love this. We bought them because my son started refusing us brushing his teeth and he wanted to do his own. This makes me feel a lot more confident that he’s brushing all his teeth better than a normal tooth brush. My daughter has the unicorn one and brushes on her own too!"
We’ve developed and refined 5 generations of Autobrushes, each one optimized for comfort and delivering an unparalleled full mouth clean for adults and kids.
Developed with you in mind
We designed the Autobrush for brushers of all shapes and sizes, but especially for kids and adults with mobility limitations and sensory sensitivities. Every feature is designed with our community in mind.
Backed by experts and data
It’s the only ADA-accepted u-brush for a reason. Four separate, independent clinical trials have shown that Autobrush removes more plaque than both manual and electric brushes— even in hard-to-reach places.

Got me back to brushing
I loathed brushing my teeth until I found Autobrush. No matter what I tried nothing would stick. Decided to give Autobrush a try (considering the Money Back Guarantee) and let it be an experiment. I’ve been consistently brushing every night, but the time it hits my sensation capacity, I’m done.
Even made it happen a few mornings in the 3 weeks of use. The strawberry nano-hap toothpaste has a very mild flavor. I’m interested in actually trying mint, which I typically find overpowering. Quick, easy, convenient. Highly recommend. Note: case purchased separately but absolutely worth it

A thorough clean in less time
I was very impressed with how well the AutoBrush cleaned my teeth. It fit comfortably in my mouth and significantly cut down my brushing time. I also found it much less technique-sensitive than a manual toothbrush, which made it easy to achieve consistent results.
To test its effectiveness, I used disclosing tablets after brushing and was very pleased with the results. The AutoBrush removed plaque effectively and provided a thorough clean with minimal effort. Overall, it is a convenient and effective option for anyone looking to simplify their oral hygiene routine.

Awesome new way to brush teeth!
Thanks Autobrush for giving me the chance to try out the auto brush tooth brush. Ya’ll this brush has 3 different vibrating motions, 3 different light settings & 3 different timers. This brush is ADA recommended and suitable for many people of all abilities. 30 seconds of run time is as effective as brushing for 2 minutes and honestly since ditching my old toothbrush and using this one my teeth & gums are feeling cleaner and looking healthier than ever! Do yourself a favor and go invest in this product…you and your mouth won’t regret it!

It’s so easy to use!
My daughter and I both have one and brush together most nights! She loves the timer and I love the color options. It’s super easy to use and actually encourages her to brush & floss and keep her braces clean.

Never using another brand again!
My toothbrush delivered an hour ago and I used it within minutes! Lol I’m NEVER using another brand again!
I’m autistic and chronically ill with sensitive teeth and have struggled for YEARS with oral hygiene because of my health. I’ve even developed chronic gum issues as a result. I’ve previously purchased a “fancy” auto silicone toothbrush and ended up wasting a good chunk of money because while it wasn’t causing me any pain, it made my oral health worse on top of crapping out on me!
After using my new autobrush for the first time, my teeth haven’t felt this clean in FOREVER. It is an adjustment for my gums but it’s still such a sensitive brush head that I won’t EVER go back to another brand. Thank you SO MUCH for creating this toothbrush and being a trustworthy, reliable and caring company! Happy tears incoming! 🥹

The Best Of The Best
I’ve tried the hard-bristle brushes, the super fancy electric ones, all of that, and nothing has made my teeth feel as clean as the Autobrush paired with the Foaming Toothbrush Cleanser.
The way this thing hits every single tooth is wild. It is so easy, so quick, and somehow still feels like I just walked out of a deep cleaning at the dentist. The different cleaning levels are no joke, each one feels thorough in its own way, and I swear my whole dental hygiene game has stepped up.
And baby, that LED light, I love it. The whitening capability is such a nice bonus, and honestly, this has become my absolute favorite toothbrush. Nothing beats it. If you’ve been struggling to find something that really gets in there and does the job, this is the one. Everybody needs to try it, because the way my teeth feel now, I’m not going back to anything else.

Just opened the box and yikes.
If I had known, my daughter’s teeth are gonna possibly bleed for the next one or two weeks I never would’ve gotten this toothbrush. She hates to brush, so I thought getting her. This one would be more fun turns out according to this note she will have discomfort for up to two weeks. They need to be more transparent in their advertising.

Honestly I'd want my money back
It's a total dud. All it does is vibrate the bristles in your teeth and it even gave me horrid tooth aches. To make matters worse it chipped my tooth from the vibrations.

Happy and healthy smiles in just 30 seconds!
I found this autobrush convenient and easy to use. It comes with great features and benefits. The design and function makes the brushing more efficient. It comes with three cleaning and timer modes . The base is not at all heavy when holding and has a nice firm grip. The Sonic Pro has a unique u-shaped brush head with soft nylon bristles where some of the bristles are blue in colour. It is very helpful that the blue bristles acts as an indicator when its time to replace the brush head. Also, I found the mint fluoride foam toothpaste to be effective and gentle. Even with being gentle, it properly clean my teeth and did not cause irritation or burning sensation. I am at ease knowing my oral health is being taken care of by Autobrush!

The AutoBrush Sonic Pro is a unique take on electric toothbrushes, featuring a U-shaped design with 360° nylon bristles that clean multiple surfaces at once. It looks and feels like a high-tech gadget, with a soft, flexible mouthpiece and built-in LED lights meant to support gum health and whitening.
It's clearly designed for convenience and speed, promising a full-mouth clean in just 30 seconds.
Using it is simple: you apply toothpaste, bite down gently on the mouthpiece, and select one of the vibration modes. The sonic technology offers up to 30,000 vibrations per minute, and you can choose from Care, Deep Clean, or Massage modes depending on your needs. It's hands-free and time-saving, making it ideal for people who want to get brushing done quickly.
In practice, the AutoBrush does well on the front teeth and is very gentle on gums, which is great for people with sensitivity.
The included light therapy feature is an interesting bonus-blue for whitening and red for gum care. However, while it's easy to use, it may not reach the back molars effectively unless the mouthpiece fits perfectly and the user moves it slightly during the cycle. That said, it can be a helpful tool for children, the elderly, or those with limited mobility.
Overall, the AutoBrush Sonic Pro is an innovative and efficient option that offers speed, simplicity, and a modern approach to brushing. It might not fully replace a traditional toothbrush for everyone, especially those concerned about thorough back molar cleaning, but it's a strong supplementary tool. It stands out for its comfort, ease of use, and thoughtful features.

A dental hygienist approval
As a dental professional for over 30 years, I can tell you this. This brush works! My teeth after a 90 second cycle felt like I brush them with my electric toothbrush I’ve used for years! The bristles in the brush are very soft, which gives another approval! Great product and the tongue brush and whitening is just an added bonus!
Yes! Autobrush is the world’s only ADA-Accepted U-shape toothbrush, clinically proven to deliver up to 5.1x better cleaning in just 30 seconds, removing up to 82% more plaque and reducing gingivitis by up to 45%.
Trusted by families, backed by experts, and validated through independent clinical studies at Salus Research, an ADA-accredited facility.
*Based on clinical data conducted at Salus Research.
Why Do Some Dentists Say “U-Shaped Brushes Don’t Work”?
It’s a common misunderstanding! Most dentists have only seen cheap look-alike U-shaped brushes and not Autobrush.
Autobrush is the only ADA-Accepted U-shaped toothbrush with patented nylon bristles (not silicone) and five clinical studies proving its effectiveness.
Our studies show measurable improvements in plaque removal and gum health that knockoffs simply can’t match.
Because they cut corners.
Independent clinical testing found that silicone-bristle knockoffs cleaned worse than not brushing at all, leaving plaque and bacteria behind.
In contrast, Autobrush’s patented nylon bristles are clinically proven to remove plaque up to 5.1× better and reduce gingivitis by up to 45% across multiple IRB-approved studies.
They’re cheaper for a reason. We’re effective for one. (And yes, Autobrush runs great sales, so stay subscribed to email/text for exclusive deals!)
Are There Clinical Studies to Prove Autobrush Works?
Absolutely, and we’re proud of them!
Autobrush is the only ADA-Accepted U-shape toothbrush backed by five independent clinical studies (and counting).
Our research shows Autobrush outperforms traditional manual brushing in both plaque removal and gum health improvement.

Is Autobrush Good for People with Disabilities?
Yes. Autobrush is a game-changer for users with disabilities, limited mobility, or sensory sensitivities.
It’s been praised by families of individuals with autism, cerebral palsy, muscular dystrophy, and others, helping users brush independently and confidently.
How effective is autobrush on the gum line?
In a clinical study by Salus Research (ADA-accredited), Autobrush users experienced:
Up to 45% reduction in gingivitis after 30 days
Up to 5.1× better plaque removal overall than a manual toothbrush
Up to 71% plaque reduction along the gum line in a single use, compared to only 3.5% for a manual brush. Read the study here
In a head-to-head comparison with a leading ADA-accepted electric toothbrush, Autobrush achieved:
29% plaque reduction along the gum line, versus 10.5% with the electric brush Read the study here
These findings show that Autobrush cleans as effectively, or better, in the areas most critical for gum health, while requiring ¼ of the brushing time.
Is Autobrush Waterproof?
Yes! Autobrush is IPX7 waterproof, meaning it’s safe for use in the shower or while rinsing under running water.
Just avoid submerging it for extended periods.
How Does Autobrush Clean the Backs of My Teeth?
Our patented brush head design surrounds every tooth: front, back, and biting surfaces.
Thousands of nylon bristles pulsate simultaneously to remove plaque from all angles.
For best results, keep the brush moving gently in a side-to-side or figure-8 motion throughout the 30-second cycle.
This ensures every tooth gets the perfect clean, even those tricky back ones!
Does Autobrush Work with Braces or Dental Work?
Yes! Autobrush is safe for braces, retainers, and other dental work.
The soft nylon bristles gently clean around brackets and wires without causing damage.
Just remember to move the brush slightly during the cycle to reach every surface.
(Always check with your orthodontist for personalized care guidance.)
Can I Use My Own Toothpaste?
Of course! You can use your favorite toothpaste with Autobrush.
Our foam toothpaste just makes things smoother (literally). It’s designed to spread evenly and reach every surface.
If using regular toothpaste, try pre-foaming or mixing it with a little water before brushing, which helps distribute it evenly.
How Often Should I Replace My Brush Head?
Every 2 months, just like a regular toothbrush.
This keeps your Autobrush performing at its best and ensures your bristles stay clean and effective.

Will This Make My Kid Lazy?
Nope, quite the opposite!
Autobrush encourages independence, not laziness.
It turns brushing into something fun, empowering kids to take charge of their routines while getting a clinically proven clean every time.
Is Autobrush Completely Hands-Free?
Not exactly, and that’s a good thing.
Autobrush must be guided with gentle motion to clean effectively. Hold it lightly and move your jaw side-to-side or in a figure-8 motion. Leaving it still will *not* produce a proper clean.
The motion helps the brush’s vibrations do their best work, especially along the gum line and back teeth.
