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.

    Frequently Asked Questions

    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.

    You can read the whole study here:

    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.

    Explanation

    • ★★★★★

      "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."

      JC 
    • ★★★★★

      "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."

      Hana 
    • ★★★★★

      "We love it. Makes brushing teeth so much easier and not a fight. My 6 year old and 9 year old both have one."

      Kelly B. 
    • ★★★★★

      "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!"

      Malyrie 
    • ★★★★★

      "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!"

    Is autobrush ADA accepted?

    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.

    👉 Read our full clinical study results

    Why Are Other U-Shaped Brushes on Amazon Cheaper?

    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 recommended for kids with disabilities?

    autobrush is the one of the best toothbrush on the market to help people with disabilities brush independently, particularly for kiddos with muscle weakness, lack of mobility, reduced motor function, and sensory disorders. We’ve heard rave reviews from customers with autism spectrum disorders, cerebral palsy, and more.

    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. 

    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.)

    What do the LED lights do? Are they safe?

    Our red and blue LED lights are non-UV and completely safe to use. Red LEDs help support gum care, while blue LEDs can enhance whitening when paired with a whitening agent, such as our whitening pens.

    What is GumDefend™️?

    GumDefend™ is autobrush's innovative feature in the new Double-sided Nylon Brush Head. It adds a fourth row of soft silicone bristles to gently care for gums, helping to stimulate them and promote gum wellness.

    Learn more about evolution of autobrush brush heads in our blog.

    Why are some bristles blue?

    The blue bristles on the autobrush serve as a visual indicator to let you know when it's time to replace the brush head. As the color fades, it indicates that the brush head should be replaced. This helps ensure that you always have a brush head that is effective and hygienic for optimal oral care.

    Don’t worry!  The blue dye used in the bristles is safe and will not stain teeth.

    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.

    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.

    What about the tongue?

    Great point! We offer a tongue scraper. Grab one here: Tongue Scraper

    Scraping the tongue is proven more effective than brushing.
