Blockchain is the biggest buzzword of the year. However, we are just now beginning to see what silly creative ways will this technology be applied. The newest example from China is a blockchain-based toothbrush by Shenzhen-based 32Teeth, currently crowdfunding the project through the JD Finance platform.

The company aims to make your teeth really clean by applying not only blockchain technology, but also facial recognition, sensors, and big data. If the company delivers its promise, the toothbrush is likely to become a favorite among OCD sufferers superheroes. The toothbrush app offers precise identification of 16 tooth surface cleanliness levels, analyzes users’ brushing activity data, and offers a powerful intelligent reminder. It even has AR function which gives you an inside look (literally) into how you brush your teeth.

The toothbrush also tries to make each of your 32 teeth—the average number of teeth in an adult—a cryptocurrency mine. Brushing your teeth regularly rewards you with AYA tokens (爱牙币, literally “love teeth coins”) which can be exchanged for more toothbrushes, toothpaste, and dental hygiene services.
