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.
