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?
In our clinical study with Salus Research, autobrush achieved 45% reduction in gingivitis and a full 20x better clean after 30 days of use.Compared to the manual toothbrushes, autobrush provided5 times greater reduction of gum inflammation.
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.
this was a great way for my kiddo to pick the flavors they like best or know which they don't like!

The Best My Teeth Have Been In Years.
I love my auto brush. I’m 76 years old and sore, gums and my hand hurt more using an electric toothbrush. I’ve been enjoying my auto brush for months so when it stopped working I was very upset. I am having a lot of pain using a regular electric toothbrush. Fortunately I remember what gave me the confidence to try autobrush was the money back guarantee. I would like to just get a new AB ASAP. Your brushes don’t hurt me at all. My dentist remarked how much better my teeth are. They are also whiter. Please get back to me soon. I don’t want my teeth to go back to how they were before I started using your autobrush. Thank you so much.

Easy to use and a great addition to our routine
AutoBrush has made brushing much easier and more enjoyable for both my son and me. My son really likes using it, organizing the brushes or the tooth paste, although younger children may need a little time to adjust because the vibrations can feel ticklish at first. After a few uses, he became much more comfortable and confident with it.
My personal advice is to pay close attention to the mouthpiece size before ordering. I originally selected the standard women’s size, but it felt too large for my mouth, so I switched to the children’s size and found it much more comfortable. Everyone’s mouth is different, so checking the measurements carefully can make a big difference.
The website is easy to navigate, the product information is clearly explained, and the brush itself is simple to use. My son and I are both very happy with AutoBrush and would definitely recommend it.

Outrageous pricing.
I need to buy my kid a replacement brush head. The picture says $25 but when I go to order it is actually $81 for one brush head for a 3-5 year old?? I'm not doing autoship yet because we are fairly new and assessing need for replacement timing. This is terrible.

Cheaping out, incomplete order, subscription rip off
Pro: First of all—my kids enjoy using the autobrush and it seems to do a good to ok job they don’t fight to brush teeth.
Cons: unfortunately vastly outweigh the pro’s.
1. Typically when you get a subscription it’s because it’s a value and you get it cheaper than if you buy the product one off times. However this is not the case for this product. I paid $90 for this sibling refresh pack yet the website price for one off purchase is $78. Based customer service about this and was basically told it’s for convenience of not having to order. Not worth $12 especially in these times.
2. As I ordered the sibling refresh pack it states it includes 2 strawberry flossers. When my package arrived it had NO flossers and NO communication as to why there were none. I had to reach out to customer support who then informed me that the strawberry flossers were out of stock. No communication on this nor does there seem to have been any intent to send once back in stock as that was never mentioned. They did offer to send the charcoal flavor which I agreed to. That package arrived yesterday and only had ONE package of flossers despite the refresher pack supposed to be having TWO. So STILL NOT giving me everything I overpaid for.
3. The toothpastes are quite expensive and do not last long.
4. The new brush head I received no longer has the blue bristles as all pictures indicate and instead has only the white. The blue are slightly stiffer which makes sense for the chewing surface of the tooth. Can only assume having the same bristles instead of two types is probably cheaper to manufacture.
SUMMARY:
Easy to use, fast, efficient. On fence for how well it actually brushes.
Subscriptions are a rip off. Double check you get everything you ordered as they will send incomplete orders and say they are complete further ripping you off by you paying for something you never receive. Shame on you autobrush.

Keeps breaking.
Purchased in April of last year and it’s been replaced 4 times, the last replacement you tried to back out of your 2 year warranty. Now it’s the 5th time the housing has cracked, has water damage of the circuit board and the LEDs stopped working. Terrible quality. I’ll be canceling my subscription and using a competitors whole mouth sonic toothbrush from now on. Pictures of current and prior damage.

Mostly good, some issues…
After receiving the brush for my 5 y/o we were both thrilled right away, then he started refusing to use it. He developed a sore in his cheek from where the brush head rubbed, despite using the size chart it was too big for him. Customer service was great and quick to replace the head for a smaller one at no cost, but as we waited for that one to come the original head developed mold in the bristle base area making it useless anyways. It is affective and cleans well, but in my opinion difficult with small children as you have to fully clean it each time, help them to get the back molars, and it is very messy due to its size/vibration with drool and toothpaste running out everywhere including all over the base that cannot be put under water to rinse or the speaker will fry. My son doesn’t like the foam toothpaste so I use our super teeth one and just rub it throughout the bristles, but I wouldn’t do that with a toothpaste that’s not safe to swallow as you will be using way more than advised. I now have my son use it before pajamas and only in the bathroom. So overall it’s affective and cute with good customer service, but not perfect or super easy, but if you are struggling to get a good clean it is worth it, just a lot of trial and error to get everything worked out. Watch for mold!!

Customer service is nightmare
This toothbrush didn’t work for our family. Im trying whole week to initiate return, finally was able to get to last page, but not it doesn’t want to let me submit request for return. They pick and choose when they answer, when i was having questions before ordering i was able to get AI immediately, now when i want to return noone responds. Website doesn’t work to submit return.
I got bundle for $180 and the brushes don’t clean the way it was promised. My kid with braces, food stayed between brackets, and i did cleaning for him. My younger brush was causing bleeding in molar area. But didn’t clean anything close to gum lime.
So this brush didn’t work for us, and I need someone to contact me about refund

I absolutely love it, I took it to my last dentist appointment and my dentist said "I wished I invented that"

Disappointed in pricing
As with any corporation, Autobrush has gone from product filling a need to profit and greed. Getting a replacement head is going to cost me as much as the original bundle? Really? And $60 toothpaste? All because I don't want to subscribe? Don't you realize a large slice of those you market to are on fixed incomes? Yet still bleeding them for every penny. Shameful.

Good but weird pricing
I love this product. Literally the bste clean I've ever had in my whole life. On par with the dentist. Only minus is the fact I'm teying to order my husband his head replacement (also got one for Christmas) and it says 25 then goes to 68 like.... that's wild. Literally the only thing stopping it from being 5 starts.

Conflicted
My kiddo loved their original autobrush. Unfortunately, the first brush head became moldy within 60 days despite being rinsed thoroughly and being stored in a well ventilated place. I decided to splurge on new ones and surprise my little guy for Christmas. I placed the order on 12/3. They were packed and the label created on 12/4 and they have not moved since then. It's been 15 days. It's disappointing for something that is such a large initial and continual investment.

Love it!
We love Autobrush, easy to use and fun too. No more fighting over brushing teeth. As an adult I love it too as my teeth feel like they do after the dentist with just brushing my teeth. Highly recommend.

Nothing gets my teeth whiter
was not expecting it to work this well. You know how some whitening products be doing the most, burning your gums or making your teeth sensitive for no reason? This one does not do that. It is gentle, but it still gets the job done.
I noticed a difference way faster than I thought I would. My smile looks brighter, my teeth look fresher, and it all feels super easy to keep up with. The formula goes on smooth, no weird taste, no mess, and it works perfectly with my Autobrush routine. I love that I can just pop it on, let it do its thing, and go about my day.
Honestly, my confidence has been up because my smile is looking good, and this kit has definitely become part of my weekly routine. If you want whitening results without the fuss or sensitivity, try this. It really surprised me in the best way.

Never received items
Items says label created and when I reached out to customer service they told what I already knew. Label was created but has never been shipped out. Pre shipment label created July 3rd and it is July 17th evening and still says pre shipment. Very disappointing. I had to order foam from Amazon.

Sharp and missing blue color
I ordered the u shaped tooth brush for my 9 year old. They are sharp and hurt to place into place and bristles look old and have no blue. I asked to be sent the correct one. They sent me the same one and changed me for both and wouldn’t refund me for either.

Not as advertised
I love this product for my kiddos, but the product says it has a blue fade indicator for the brush heads, but that isn't the case. I ordered a 2 pack of 6-8 year old replacement brushes and they didn't have the blue fade. I thought it was a singular issue and returned for a replacement and was sent another pack with the same issue.

This is what the video said, so like its kina good, but like not good at the same time soooooo.
I liked it, but when my brother used it, it was like a mess, so yes ummm, I would recommend this for older children, but I use it very well, and so yes.Sincerely, Your friend,Kai💙

No Blue Fade
I ordered the 2 pack replacement heads in 3-5 size and neither of them came with blue fade indicator promised on the back of the box. I ordered this replacement because I ordered the 6-8 size for my 6 year with the brush unit and it was way too big. I also ordered a brush for my 4 year old (with the 3-5 size head) and the heads that arrived with the brushes came with the blue fade indicator. So now my 4 year olds brush has blue fade but my 6 year olds does not. Very excited about the new brushes but a little disappointed about the replacement heads as I was expecting consistency.
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.
Choose based on your age group or mouth size using our simple Size Chart, or contact our team anytime for personal help.
If it still doesn’t fit quite right, no worries, we’ve got a Perfect Fit Promise: If it’s not a good fit, we’ll fix it for free.
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.
