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.

    To get the best deals, make sure you're signed up for email and texts.

    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.

    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."

      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!"
