While much attention focuses on ZERObrush as a custom-fit, whole-mouth device to replace your toothbrush, our vision extends to the next generation of precision and personal oral care products.
We're set to revolutionize at-home oral care, starting with the very act of brushing. This is the first in a series of articles, where I will first define the problem and then explore how our technology, particularly AI vision models, will automate and commercialize this concept.
How precision medicine is about to transform periodontal care with custom-fit devices and therapeutic chemistry
The $64 Billion Problem Hiding in Your Mouth.
Every time you brush your teeth, you're fighting a losing battle.
Not because you're doing it wrong. Not because you need a better toothbrush. But because the very design of traditional oral care is fundamentally flawed for where the real action happens in gum disease.
The dirty secret? The most critical areas where periodontal disease develops—those deep pockets between your gums and teeth—are virtually unreachable by conventional brushing. It's like trying to clean the inside of a narrow bottle with a paintbrush.
This isn't just an inconvenience. It's a $64 billion annual healthcare problem affecting over 47% of adults over 30. But what if I told you that breakthrough technology could change everything?
Where Toothbrushes Fail (And Why It Matters)
Let me paint you a picture of what's actually happening in your mouth right now.
The Subgingival Battlefield
Below your gum line exists a complex ecosystem of bacteria, many of which thrive in oxygen-free environments. These periodontal pockets—especially those deeper than 4mm—become perfect breeding grounds for the kind of anaerobic bacteria that cause serious gum disease.
The Dilution Disaster
Even when we try to use therapeutic mouthwashes or gels, they face an immediate problem: your saliva. Within minutes, these carefully formulated treatments are diluted and washed away before they can do their job.
The Compliance Catastrophe
Traditional treatments often require multiple daily applications, perfect technique, and sustained patient compliance. The reality? Most people struggle with basic brushing and flossing, let alone complex therapeutic protocols.
Your toothbrush? It can't even reach these areas, let alone deliver therapeutic agents where they're needed most. And on average a toothbrush is used for 45 sec, making it less than 1 sec per tooth surface, and we miss out the most critical areas - hard to reach, which compounds the problem.
The result is a healthcare system spending billions on treatments that barely scratch the surface of the problem.
The Chemistry That Could Change Everything
Here's what most people don't know: we already have incredibly effective therapeutic agents for gum disease. The problem isn't the chemistry—it's the delivery. I won’t bore you with the details, but chemistry such as Chlorhexidine, Stannus Flouride, when properly delivered achieve reduction is gingivitis.
Enter the Custom-Fit Revolution
Now imagine a different approach entirely.
What if instead of hoping a mouthwash reaches the right spots, you had a device custom-made for your exact mouth anatomy?
What if this device could deliver therapeutic agents directly to diseased gum pockets with pharmaceutical precision?
What if treatment took a few minutes a day instead of constant vigilance?
What if this were all automated with a device which precisely applies it to the affected areas.
This isn't science fiction. This is one of the areas we will achieve in ZERObrush.
3D Printing Meets Precision Medicine
But we're just getting started.
Advanced 3D printing technology now enables creation of personalized oral delivery devices using patient-specific scanning data[21][27]. These devices can be manufactured within hours and customized for:
- Specific drug concentrations based on disease severity
- Controlled release rates maintaining therapeutic levels for days or weeks
- Multi-agent delivery combining antimicrobials, anti-inflammatories, and regenerative compounds
- Targeted application to specific problem areas while protecting healthy tissue
With precision delivery solved, an entire arsenal of therapeutic chemistry becomes available
Why This Matters Now
We're at an inflection point in oral healthcare.
The Technology Is Ready
ZERObrush has perfected the 3D printing, biocompatible materials to enable practical, affordable custom devices.
The Science Is Proven
Multiple clinical trials demonstrate superior outcomes with precision delivery systems compared to traditional methods.
The Need Is Urgent
Periodontal disease affects nearly half of American adults and is linked to heart disease, diabetes, and other systemic conditions. The current approach simply isn't working at scale.
The Bottom Line
Your toothbrush isn't the problem—it's just not the solution. Brushing needs to change, and ZERObrush is a true platform to achieve not only your cleaning (replacing toothbrush) but also manage your Oral Care when you’re outside the dental office. The breakthrough in precision care is here.
