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.

Leading the Category We Created: Autobrush Outperforms Knockoffs (Clinically and Credibly)

Leading the Category We Created: Autobrush Outperforms Knockoffs (Clinically and Credibly)

The difference isn’t subtle, it’s clinical.

 

New independent research proves what we’ve known all along: imitation can’t compare.

Autobrush isn’t just another U-shaped toothbrush. We created the category, and now, clinical data confirms why it’s the only ADA-accepted U-shaped toothbrush on the market.

 

The Results Are In

 

In our 5th clinical trial, Autobrush outperformed silicone knockoffs across every surface of the mouth:

  • Up to 6.9× better full-mouth clean
  • Up to 10× better in hard-to-reach areas
  • 100% of participants saw better results with Autobrush

 

That’s not marketing, that’s measurable science.

These findings underscore what sets Autobrush apart: precision-engineered nylon bristles, full mouth coverage, and a design built from years of iteration and clinical testing.

 

The Original. Not an Imitation.

 

Autobrush didn’t join the U-brush category, we created it.

When we launched the first U-shaped brush, it wasn’t just about speed. It was about transforming oral health through innovation and accessibility.

Since then, the market has flooded with low-cost silicone replicas. But without data, without rigorous testing, and without the American Dental Association’s Seal of Acceptance, they simply can’t claim the same results.

Autobrush is the first and only U-shaped toothbrush recognized by the American Dental Association (ADA) as both safe and effective for plaque removal and gingivitis prevention.

Proof that we don’t just innovate, we validate.

 

What Makes the Difference?

 

Silicone imitations solely rely on soft rubber that glide over the surface of teeth without truly cleaning them.

 

 

Autobrush, on the other hand, is built on clinical engineering:

  • Patented Nylon Bristles: The only material proven to remove plaque effectively
  • GumDefend™ Technology: 4th row of silicone bristles to massage the gums
  • ADA Seal of Acceptance: Independent validation of both safety and effectiveness

 

Why Clinical Proof Matters

 

Anyone can make claims. Few can prove them.

Our fifth clinical trial marks another step toward redefining oral health, backed by the same rigor trusted by dental professionals and global research bodies. Every study reinforces the same result: Autobrush cleans better, faster, and more completely than imitation.

That’s what leadership in innovation looks like. Not just being first, but being proven.

 

A Message to Our Community

 

We’re not here to compete with imitators.

We’re here to set the standard, and to keep raising it.

Every brush we build, every study we conduct, and every ADA-Accepted innovation we release is driven by one goal: redefining what “effective brushing” really means.

Autobrush is the original, and the only clinically validated U-shaped toothbrush built for real results.
