32teeth Tooth Guardian is a blockchain-enabled smart instructional toothbrush designed for the Bass brushing method. Adhering to the principles of preventive medicine and the philosophy that “clean teeth stay healthy,” it digitizes consensus-based professional oral prevention practices. By integrating blockchain technology and Token Economy 2.0, it provides users with a comprehensive care and incentive system. Leveraging a suite of core technologies, it ensures effective cleaning while enabling users to earn rewards for brushing, thereby encouraging the development of consistent oral hygiene habits.

The Bass Method is a toothbrushing technique jointly recommended by the American Dental Association (ADA) and the Chinese Stomatological Association. Although a wide variety of toothbrushes are available on the market, failing to adopt proper brushing techniques renders any tool ineffective at removing dental plaque—the primary culprit behind most oral diseases. This results in the awkward reality that 800 million people in China “pretend to brush their teeth” every morning.
32teeth Huya Zhe Toothbrush: Embedded with the Bass brushing method, this toothbrush utilizes nine-axis sensors and facial recognition technology. Developed in collaboration with the State Key Laboratory of Inertial Navigation at Beihang University, its algorithms effectively record users’ brushing motions and accurately assess the cleanliness of all 16 tooth surfaces, digitizing brushing behavior to enable effective monitoring and evaluation.
The “Toothbrushing Monitoring Device and Toothbrushing Monitoring System” has been refined over two years, used by more than 17,000 people, and tested by over 3,000 physicians, leading to continuous improvements and the acquisition of a national utility model patent.
Zheng Hong, founder of 32teeth, revealed to reporters: “Through my exchanges with numerous dental experts, I have learned that oral health remains a significant issue abroad, including in developed countries. The widespread adoption of electric toothbrushes has not significantly reduced the incidence of oral diseases, whereas communities with zero cavities overseas are the result of systematic medical prevention. Therefore, we adopted the concept of preventive medicine in our research and development. Unlike most products on the market that target convenience-seeking consumers, this path was destined to be arduous. As pioneers, my team and I patiently refined our product and explored many directions, ultimately succeeding in developing the ‘Tooth Guardian’ toothbrush.”

The 32teeth app offers detailed video tutorials on the Bass brushing technique, allowing users to learn the correct way to brush their teeth by following the instructional videos. Additionally, the Huyazhe toothbrush features a robust smart reminder function.
When each tooth surface meets the standards of the Bass brushing technique during brushing, the main unit of the toothbrush will gently vibrate to prompt you to move on to the next surface. After brushing, the app displays detailed brushing information, including the cleanliness level of each tooth surface, and evaluates performance using three key metrics: Cleaning Index, Posture Index, and Diligence Index.
For tooth surfaces that were not brushed thoroughly or were missed, users can select the one-touch touch-up brushing feature and follow the instructional video to re-brush those specific areas. This is particularly beneficial for children and teenagers; using the Huyazhe toothbrush ensures thorough cleaning, helping to prevent dental diseases and cultivate proper brushing habits that offer lifelong benefits. This gives mothers peace of mind and reduces their worries.

Who says brushing your teeth has to be a rigid, mirror-bound routine? The AR feature of the Huya Zhe toothbrush lets you transform your look while you brush. In the morning, your cute avatar in the app brightens your mood for the day ahead; late at night, turn into an adorable cat-like character to shed your fatigue and drift off to sleep with ease.
Huyazhe Toothbrush: Not only smart and effective at cleaning, but also fun, making you love brushing your teeth.

The 32teeth Tooth Guardian toothbrush integrates the latest blockchain technology, where brushing your teeth is equivalent to “mining.” The mined token rewards are called Aiya Coins, which can be directly redeemed for goods and services. Aiya Coin (AYA, AI YA TOKEN) is a points system issued and managed on the blockchain, falling within the scope of Token Economy 2.0.
Token Economy 1.0 is typified by Bitcoin and the subsequent wave of Initial Coin Offerings (ICOs) for various digital currencies. The 2.0 era, however, signifies the application of blockchain technology and tokens within specific industries, moving beyond the concerns surrounding worthless “vaporware coins” to achieve tangible, real-world implementation.
How can you earn Aiya Coins by brushing your teeth? In short, 32teeth has established exclusive mining pools and public mining pools. When you use the Huyazhe (Tooth Guardian) toothbrush, your brushing behavior is digitized, allowing you to earn the digital asset Aiya Coins from the exclusive mining pool while brushing. The cleaner you brush your teeth, the greater the reward.
Meanwhile, users can complete designated brushing tasks in public mining pools to earn hashrate points and continue receiving rewards. 32teeth will periodically release iTooth Coins into the public pool based on the actual total hashrate, allowing users to continue mining.
Aiya Coins can be redeemed for products such as toothpaste, toothbrushes, dental floss, and data cards, as well as services like dental cleaning. The range of redeemable items is continuously expanding and will cover all aspects of daily life in the future.
“Love Teeth Angel Plan” is a dental care initiative launched by 32teeth based on the concept of preventive medicine. For dentists, using Huya Zhe toothbrushes and continuously earning Love Teeth Coins can serve as an effective incentive. Oral health education can achieve automatic, spontaneous, and self-propagating dissemination, potentially leading to sustained and automatic growth in patient acquisition, while significantly enhancing clinic customer loyalty.
In addition, 32teeth’s facial recognition technology can be integrated with conventional toothbrushes to digitize brushing time data, allowing users to mine AiYa Coins in a public mining pool. This greatly facilitates dentists’ participation in the AiYa Angel Program, enabling the use of AiYa Coins as incentives for all patients.
