For people obsessed with their skin, there are special video cameras that can give you a good look at your blemishes. Prophix is a toothbrush that does the same thing, but with the inside of your mouth. You might think you are getting your teeth and gums clean, but without being able to see you might not be.
Prophix has a built in video camera that streams video to your smartphone via Wi-Fi and Bluetooth. It can also take still shots of your teeth if you want. The idea is to allow you to see just how clean your teeth are and to clean them better. I imagine some really crazy people will use this to post tooth selfies to Instagram.
The Prophix toothbrush is available for pre-order for $299(USD) and includes several heads for brushing and cleaning under the gumline. A fancy bundle also has a scaler to remove plaque and sells for $324 during the pre-order period. If you wait until the retail launch, you will spend $100 more per bundle.
