How far the smart toothbrush can contribute to cavity prevention is one thing that is of great interest. The site will soon be available on the crowdfunding site Indigogo.
Oclean | Sonic Smart Electric Toothbrush
This Chinese startup has a gyroscope built into the toothbrush. By brushing one's teeth, the gyroscope measures the angle and strength of the toothbrush's movement and contact with the teeth, and a smartphone app displays the measurement results and tips for improvement.
This would be just fine for infants. Baby teeth are prone to cavities and dentists will be able to easily advise on points to improve tooth brushing. The key price is not yet known, but based on the trend of smart devices so far, it will be around 200$.
