CONF3RENCE 2025 took place in Dortmund, Germany, bringing together over 4,000 participants from across AI, blockchain, and Web3 industries. This year, BrushO proudly joined the event, presenting how smart oral care connects with cutting-edge technologies like AI, DePIN, and health tech innovation. In this article, we’ll highlight why CONF3RENCE matters, BrushO’s contributions, and the key takeaways for the global Web3 community.

CONF3RENCE is one of Europe’s largest Web3 and AI gatherings, held on September 3–4, 2025, at the Signal Iduna Park in Dortmund. With over 4,000 attendees, 120 global speakers, and 150 exhibitors, it serves as a meeting point for industry leaders, startups, and innovators.
The event’s mission is to explore how emerging technologies—AI, blockchain, Web3, and DePIN (Decentralized Physical Infrastructure Networks)—are shaping industries such as finance, logistics, and now, healthcare.
CONF3RENCE stands out because it connects theory with practice. It’s not only about blockchain or AI hype; it’s about real-world adoption.
For startups like BrushO, this event is a gateway to global networks, helping health tech innovators find their place in the Web3 ecosystem.
As a smart oral care brand, BrushO introduced its AI-powered electric toothbrush and explained how oral care data can contribute to broader health ecosystems.
Key highlights from BrushO’s showcase:
AI is transforming dentistry and personal health:
BrushO’s presence at CONF3RENCE showed how daily brushing can become part of a larger preventive health strategy.

DePIN (Decentralized Physical Infrastructure Networks) is one of the hottest topics in Web3. It rewards users who contribute physical data or infrastructure to a blockchain network.
This aligns perfectly with CONF3RENCE’s mission: bridging the gap between digital innovation and physical impact.
1. Health Tech Is Rising: Oral care can be part of Web3’s push into healthcare.
2. Cross-Industry Collaboration: CONF3RENCE showed that finance, energy, and health can learn from each other.
3. User Data Empowerment: BrushO highlighted how individuals can own and even monetize their health data responsibly.
Q1: What is CONF3RENCE 2025 about?
It’s a European Web3 and AI event connecting 4,000+ leaders to explore real-world use cases in emerging technologies.
Q2: Why did BrushO attend CONF3RENCE?
To showcase how AI-powered oral care and DePIN models can reshape preventive health.
Q3: How does BrushO connect AI and Web3?
By combining smart toothbrush data with decentralized networks, enabling better oral health while empowering users with data ownership.
Q4: What is DePIN, and why is it relevant to health tech?
DePIN decentralizes infrastructure, rewarding users for contributing real-world data—BrushO applies this to oral health.
BrushO’s participation in CONF3RENCE 2025 was more than sponsorship—it was about showing how AI, Web3, and health tech can work together to create smarter, healthier futures. By joining the Web3 community in Germany, BrushO positioned itself as a pioneer at the crossroads of oral health innovation and decentralized technology.

Missed molars often do not show up as a single obvious bad session. They appear as a repeated weekly pattern of shortened posterior coverage, rushed transitions, or one-sided neglect. Weekly trend review makes those back-tooth habits visible early enough to fix calmly.

Sparkling water can look harmless at night because it has no sugar, but the fizz and acidity can keep teeth in a lower-pH environment longer when saliva is already slowing down. The practical issue is timing, frequency, and what else happens before bed.

A sore throat often changes how people swallow, breathe, hydrate, and clean the mouth, and those shifts can leave the tongue feeling rougher and more coated. The coating is usually a sign that saliva flow, debris clearance, and daily cleaning have become less efficient.

Tiny seed shells can slide into irritated gum margins and stay there longer than people expect, especially when the tissue is already puffy. The discomfort often looks mysterious at first, but the pattern is usually very local and very mechanical.

Root surfaces never begin with enamel. They are protected by cementum, which is softer and more vulnerable when gum recession exposes it to brushing pressure, dryness, and acid. That material difference explains why exposed roots can feel sensitive and wear faster.

Morning mints can cover dry breath for a few minutes, but they do not fix the low saliva pattern that often caused the odor in the first place. When dryness keeps returning, the smarter move is to notice the whole morning mouth pattern rather than chase it with stronger flavor.

Molar fissures look like tiny surface lines, but their narrow shape can trap plaque, sugars, softened starches, and acids deeper than the eye can judge. The real challenge is that back tooth grooves can stay active between brushings even when the chewing surface appears clean.

Evening brushing often becomes rushed by fatigue, distractions, and the false sense that the day is already over. Live zone prompts help by guiding attention through the mouth in real time, keeping timing, coverage, and pressure from drifting when self-monitoring is weakest.

Chewy vitamins can look harmless because they are sold as part of a health routine, but their sticky texture and sugar content can linger in molar grooves long after swallowing. The cavity issue is usually about retention time, bedtime timing, and repeated contact on hard to clean back teeth.

Accessory canals are tiny side pathways branching from the main root canal system, and they help explain why irritation inside a tooth does not stay confined to one straight line. When inflammation reaches these routes, discomfort can spread into nearby ligament or bone in less obvious patterns.
