Tooth Guardian Lets You See What Your Dentist Sees, Every Time You Brush

by Paul Strauss

Here’s a concept design that I actually think is quite smart. It’s a toothbrush with a built-in camera to help you make sure to get all the built-up gunk off your teeth when you brush.


Designed by Yu-Hsin Lin, Chu-Che Chang and Shang-Hsuan Lu, the Tooth Guardian would have a tiny CCD camera on the backside of its head, capturing a real-time image of your teeth and gums as you brush. An LED ring encircles the camera lens and automatically turns on when you place the toothbrush in your mouth.


The toothbrush would wirelessly transmit its images to an LCD screen built into your mirror, so you can see how good a job you’re doing keeping your choppers pearly white.

By installing the camera on the flip-side of the head, it allows the bristles to be easily replaced, but means you won’t see the surface you’re brushing right now, but what you need to brush when you flip the toothbrush over. Still it’s a great idea for making sure you’re doing a good job when brushing. When done, the Tooth Guardian stows in a handy UV sanitizer to help kill any extraneous germs.


While the Tooth Guardian design was a recipient of a 2011 red dot design concept award, there’s no word on if or when it will be produced. However, everything here is readily available technology, so I don’t see why someone can’t bring these to market sometime soon.
