Onvi has something different. It has created a toothbrush with a video camera attached to it. The camera shows you a view of the inside of your mouth when you are using the brush. It transmits the video to an app on your smartphone. You can then look at the smartphone to see if you are hitting all the right spots.
You can take snapshots of your teeth with the camera and then compare the pictures over time to see if you’re making improvements in brushing. The app is available for pre-order today.
