Oral health is crucial to our quality of life, affecting our ability to speak, eat, and even breathe. However, maintaining oral health has become a significant challenge for people worldwide. According to the World Health Organization, 3.5 billion people suffer from oral diseases, which is more than half of the global population. Over the past 30 years, the number of cases has increased by 1 billion due to factors such as unhealthy diets, trauma, and poor oral hygiene. Oral diseases are often insidious; without good daily care and regular check-ups, they are usually detected too late. Additionally, the high cost and need for professional support in oral care make it unaffordable for many, leading to worsening oral health issues.

Paradoxically, despite the large number of patients and strong market demand, the oral health industry has not seen corresponding growth and benefits. One major issue is the lack of comprehensive oral health data, which hinders industry development. The high costs associated with oral healthcare limit its accessibility, resulting in data that lacks universality. This impacts market research, treatment technology development, product innovation, and sales, creating a vicious cycle of high entry barriers, high costs, and high prices.
Another issue is the difficulty in building an integrated industry platform. The oral health industry spans sectors such as personal care, beauty, insurance, and medical care, each developing in isolation without shared interests, leading to severe information asymmetry. Users struggle to access comprehensive oral health services, limiting the formation of a global oral health ecosystem.
Despite advancements in smart technology making devices like electric toothbrushes popular, challenges such as high prices and the risk of personal oral health data being stored on centralized servers remain.
How can we transform the current state of the oral health ecosystem? We need an innovative solution that reduces the cost of maintaining oral health and promotes the development of the industry. BrushO was created to meet this need.
BrushO aims to usher in a new era of oral health by building a global oral health ecosystem. People can engage with the ecosystem in unprecedented ways and be rewarded for their participation. This platform consists of the BrushO Network and the BrushO smart toothbrush.
BrushO Network is a smart oral health DePIN platform based on Web3.0 technology. Oral health data generated by users while using the BrushO smart toothbrush is collected on the platform, with blockchain technology ensuring the security and privacy of this data. On the BrushO Network, users own and control their oral health data, which they can convert into valuable digital assets.
Institutions and companies in the oral health industry can access scalable, real-world oral health data through BrushO to meet their business needs. This reduces project costs and allows them to offer better services and prices to users, creating a flywheel effect.
The BrushO Network also lowers the barriers to entry into the oral health industry. All compliant software and hardware can connect to the network, leveraging its pre-built distributed infrastructure and data value network. This will drive the industry towards diversity, openness, equality, and prosperity.
The BrushO smart toothbrush is BrushO’s first oral health sensor device. It uses various sensors and AI algorithms to monitor and optimize users’ brushing habits and introduces the innovative “Brush And Earn” model. Users earn token rewards through their daily brushing activities, reducing usage costs and significantly increasing user engagement and willingness to use the product. It also helps users understand and improve their oral health.
Starting with the smart toothbrush, BrushO will continue to develop more smart oral health hardware, creating a larger distributed sensor network. This will lay a solid foundation for building a global oral health ecosystem.

An in-depth exploration of the three principal hardness testing methodologies used in dental enamel research—Vickers, Knoop, and nanoindentation—and what they reveal about remineralization, erosion, and the anisotropic mechanical properties of the body's hardest tissue.

A deep dive into silver diamine fluoride—its mechanism of action combining silver's antimicrobial properties with fluoride's remineralization, FDA approval history, clinical efficacy data for arresting cavitated lesions, and practical considerations including the characteristic dark staining.

Reviews the emerging field of oral probiotics—examining specific strains (S. salivarius K12/M18, L. reuteri) and their mechanisms including competitive exclusion, bacteriocin production, and immune modulation. Evaluates clinical evidence for halitosis reduction, caries prevention, and periodontal health.

Explores oral lichen planus—a T-cell mediated chronic inflammatory condition affecting 1-2% of the population. Covers subtypes, diagnostic hallmarks, malignant transformation risk, and management from topical corticosteroids to systemic immunosuppressants.

Explores the dental implications of intermittent fasting—how prolonged fasting windows alter salivary flow, pH buffering capacity, and the oral microbiome, potentially increasing or decreasing cavity risk depending on hydration and meal composition.

A technical deep dive into the hardware powering AI toothbrushes—how 6-axis inertial measurement units achieve real-time orientation tracking, zone classification, and brushing motion analysis through sensor fusion algorithms with sub-second latency.

Examines Hunter-Schreger bands—alternating zones of decussating enamel prisms visible under polarized light. Explains how this crack-deflection architecture dramatically increases enamel fracture toughness, and its clinical relevance for understanding enamel's remarkable durability.

Explains the biological mechanisms behind age-related tooth darkening—how progressive deposition of peritubular dentin within dentinal tubules creates sclerotic dentin, altering light transmission. Covers differentiation from pathological sclerosis and implications for whitening treatment expectations.

Investigates dental pulp stones—their prevalence (up to 50% in some populations), classification, hypothesized etiologies, and clinical significance for endodontic access and treatment planning.

Modern AI toothbrushes perform complex computations — zone classification, pressure detection, stroke recognition — entirely on-device using edge computing architectures, eliminating the latency, privacy, and connectivity constraints of cloud-dependent processing. This article dissects the hardware, neural network architectures, and real-time inference pipeline that enable a toothbrush to understand brushing behavior.
