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.

After three months I came back and my dentist was impressed and excited at how clean my teeth were and how my gum inflammation had improved. The hygienist told me to keep doing what I'm doing, and said it was my best check up yet. They were asking questions about how to use it and how often I replace the brush heads. My teeth are cleaner, my breath is fresher, and I can definitely tell that my teeth are whiter. I love it, you'll love it.

The brush head provides a much deeper cleaning than the Phillips electric toothbrush I've used for years. I could tell after using the AutoBrush just once it was hitting areas of my gums that hadn't gotten attention in the past. The settings also ensure that I'm brushing consistently with recommended practices and save time since for 30 seconds my entire mouth is getting attention.
Robert Borho
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. I'm not going back to anything else.

Not all U-shaped brushes are created equal
Most U-shaped brushes use silicone bristles. Autobrush uses patented nylon — and it's the only one ADA-accepted and clinically proven to clean up to 5.1x better.*

Any last questions?
What if I order the wrong size?
No stress. Our Perfect Fit Promise means if your brush head doesn't fit, we'll make it right for free. It's fully self-serve and takes just a few minutes. Reach out to our team and we'll get you sorted.
How do I know Autobrush is working?
Technique matters most. Move the brush side-to-side and in figure-eight motions to achieve clinical results. Holding it still won't give you a full clean. After brushing, your teeth should feel smooth and you should visibly see plaque removed. You can also use an at-home plaque test to see your own before and after. If you're having trouble reaching back molars, check your technique first, then confirm you have the right size. A too-small brush head can't reach your back teeth.
What if I order the wrong size?
Our clinical data shows measurable gingivitis reduction starting at 15 days,* with up to 45% better gingivitis reduction at 30 days.* Most customers notice their teeth feeling cleaner and their gums less sensitive within the first two weeks.
