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.

Morning lip dryness often points to nighttime mouth breathing because airflow and lower saliva during sleep can dry the lips and oral tissues faster than people expect.

Morning jaw fatigue can be an early sign of overnight clenching because repeated nighttime force strains muscles, teeth, and supporting tissues even before obvious wear appears.

Children often develop cavities faster than adults because enamel is thinner, routines are less stable, and snacking patterns keep feeding plaque. Understanding those differences helps parents prevent problems earlier.

Consistent brushing streaks matter more than one perfect session because oral health improves through repeated, stable behavior rather than isolated high-performance brushing moments.

The tooth pulp helps explain why some dental pain feels deep, lingering, and hard to ignore. Once irritation reaches inner tissue, the tooth reacts very differently than it does with surface-level sensitivity.

Sharp pain from cold drinks often points to exposed dentin, enamel wear, gum recession, or a developing crack. Knowing what triggers it helps people act before sensitivity turns into a bigger problem.

Jawbone loss can begin after teeth are missing because the bone no longer receives the same functional stimulation from chewing. The change is gradual, but it affects stability, bite patterns, and long-term oral structure.

Dry mouth can turn manageable oral issues into persistent discomfort because saliva supports cleaning, buffering, and tissue protection. Once saliva drops, plaque, irritation, and sensitivity can escalate faster than expected.

Dentin tubules help explain why small changes in enamel or gum coverage can make teeth react quickly. Once these pathways are exposed, everyday triggers like cold, sweetness, or brushing pressure can feel much stronger.

Brushing heatmaps make missed zones visible by turning brushing behavior into a pattern people can review. That matters because most people repeat the same blind spots without realizing it.
