Parents are always on the lookout for ways to make brushing easier—and more effective—for their kids.
So when U-shaped toothbrushes like Autobrush® started trending on social media, many families wondered: Does it actually work, or is it just another gadget?
In this post, our Naperville pediatric dentists will discuss everything you need to know about Autobrush for kids. We’ll answer:
- What is Autobrush?
- Are all U-shaped toothbrushes created equal?
- Is Autobrush effective? Is there research to support its claims?
- Who can benefit from an Autobrush toothbrush?
- How do kids use the device?
- What does a Naperville pediatric dentist think of Autobrush for kids?
What is Autobrush?
Autobrush is an automatic, U-shaped toothbrush designed to make brushing faster and easier, especially for kids who struggle with brushing on their own.
The device uses gentle sonic vibrations and soft nylon bristles arranged in a mouthpiece to clean multiple tooth surfaces at once.
Kids simply apply toothpaste, pop the device in their mouth, and move it slightly side to side and in a figure-eight motion while it generates vibrations for about 30 seconds per brushing cycle.
Autobrush also adds lights, sounds, and music to make brushing more exciting for young children, which can help improve consistency and motivation.
How Does Autobrush Work?
The toothbrush features a U-shaped head that looks a little like a mouthguard or Invisalign aligner. Inside are up to 58,000 tapered nylon bristles positioned at the optimal angles to reach the front, back, and chewing surfaces of each tooth.
When activated, sonic technology delivers thousands of micro-vibrations, helping the bristles gently remove plaque and debris from all sides of the teeth simultaneously.
The latest model also has three cleaning modes, as well as light settings, including red light, which helps to reduce inflammation and support gum health, blue light for teeth whitening, and a combination of the two.
I’ve Seen Cheaper Versions Online. Are all U-Shaped Toothbrushes the Same?
No! This is where the confusion comes in. You’ll find tons of U-shaped “autobrushes” on Amazon and other online sources. While they may look similar to the Autobrush® brand devices, they do not work the same.
Most of the inexpensive U-shaped toothbrushes use soft silicone nubs instead of nylon bristles. Unfortunately, studies have shown that silicone tips don’t effectively remove plaque because they lack the friction needed for mechanical cleaning.
Autobrush, on the other hand, uses angled nylon bristles, similar to those found in a traditional toothbrush. It’s also the only U-shaped toothbrush accepted by the American Dental Association (ADA), which means it has been independently tested and proven safe and effective when used as directed.
Is Autobrush Effective? What the Science Says
Autobrush has been tested in five clinical studies, including studies done by Salus, an independent, ADA-accredited research facility, comparing its results against both manual and electric toothbrushes.
Here’s what the research found:
- Up to 5.1× better plaque removal than a manual toothbrush
- Up to 45% reduction in gingivitis compared to manual brushing
- 82% more plaque removal in hard-to-reach places
- Kids ages 5–8 brushed up to 26.6× better and had up to 20.3x more plaque removal around the gumline with Autobrush than with a manual toothbrush
- Clinically proven safe and effective for both children and adults
The results of the studies are promising! However, the study of Autobrush’s plaque removal efficacy in children only contained 22 subjects. Additional research with larger subject sizes would bolster the claims.

How to Use Autobrush Correctly
For the best results:
- Make sure your child’s mouthpiece fits comfortably and that the bristles make contact with the teeth on all sides.
- Use a small amount of fluoride toothpaste (a smear for toddlers and a pea-sized amount for kids ages 2 and up) on both sides of the mouthpiece.
- Encourage your child to move the brush gently side to side and in figure-eight motions during the 30-second cycle to help the bristles reach the back teeth and along the gumline.
- Have your kiddo spit out any remaining toothpaste.
- Rinse the mouthpiece after each use and replace it every two months, similar to a regular toothbrush.
Parents should still supervise brushing, especially for younger children, to make sure the technique is correct.
Note: Autobrush does NOT take the place of flossing. Once any two teeth are touching, you should floss your child’s teeth once a day in addition to brushing twice daily.
Who Might Benefit Most from Autobrush for Kids?
While Autobrush is designed for all ages, certain children may benefit the most, including those who:
- Have trouble reaching back teeth or brushing for the full two minutes
- Have braces or other fixed appliances
- Experience sensory sensitivities or motor challenges
- Resist brushing or need extra motivation to maintain a daily routine
The semi-hands-free design, colorful design, and built-in music and lights make brushing more engaging for young kids, while the automatic function ensures a consistent clean regardless of manual dexterity.
Does Autobrush Work for Kids With Braces or Other Orthodontic Appliances?
Yes! Autobrush is safe for braces, retainers, and other orthodontic appliances, as well as dental restorations.
The soft nylon bristles clean gently around brackets and wires without causing damage, and the design helps reach areas that can be tough to access with a regular toothbrush.
Still, it’s always a good idea to check with your orthodontist or pediatric dentist for personalized recommendations.
Can You Use Regular Toothpaste With Autobrush?
Yes, you can use regular toothpaste with Autobrush. However, some reviewers say that the Autobrush brand foaming toothpaste does work slightly better with the device.
Our Expert Perspective
At Innovative Pediatric Dentistry, we recognize that one toothbrush won’t work perfectly for every child. For kids who need help brushing longer or more effectively, or who find brushing difficult due to sensory sensitivities, Autobrush may be a beneficial addition to their oral care routine.
When paired with regular dental visits, flossing, and fluoride toothpaste, it can help set the stage for lifelong healthy brushing habits.
That doesn’t mean parents should run out and purchase an Autobrush for kids, though. If your child is already an excellent brusher and has good technique, it’s ideal to stick with the method they’ve been using.
Autobrush for Kids: The Bottom Line
Most U-shaped brushes don’t perform well, but Autobrush is the exception. Because it has the ADA seal of approval, you’ll have peace of mind knowing that it has been clinically validated and the company’s claims are supported by research.
It’s an option worth considering for families who struggle with daily oral hygiene. But to be sure you’re getting a legit Autobrush for kids, you may want to purchase it from the company’s website.
