Almost any child at any age refuse to brush their teeth, and it is too annoying for parents to convince them to brush their teeth regularly. Pediatric dental disease, commonly called childhood tooth decay, is the most common chronic childhood disease in the world. This is five times higher than asthma and seven times higher than hay fever. If left untreated, tooth decay has consequences that go beyond cosmetic problems. Widespread tooth decay can impair a child's quality of life, slow social development, and lead to problems such as malnutrition, infection, and eating and speaking problems. With poor oral health, children may be at risk for heart disease, diabetes, dementia and other problems in the future. We developed a smart tooth brush which is connecting to an mobile application (Game) so children not only enjoy playing game, but also, they want to use this tooth brush more and more. The minimum viable product includes hardware that tracks the movement of the toothbrush, and a game to improve the quality of brushing are ready. Parents can monitor the brushing process and teach them how to use tooth brush more effectively. We built the minimum viable product and tested the product. We are sure that our target market will accept the product. It is easy to use, user-friendly and fun, especially for children.
