The toothbrush of the future will have a special sensor on it that will detect if you still have bacteria on your teeth. 

The toothbrush will let you know as soon as your teeth are perfectly clean!  That means more and more children will grow up with strong, healthy teeth.

Additional Features:

1. Waterproof

2. Battery lives forever

3. If the brush senses a cavity it will send an email to you and your dentist.

The Fascinating Toothbrush Sensor

The Design Process

  1. At first we thought the person’s teeth would glow, but then we decided to make the toothbrush glow instead.

  2. We also thought if you drink water, the tooth would glow but that just wouldn’t work either.

  3. We also thought that the toothpaste would make your teeth glow, but then we changed it to the toothbrush instead and added bacteria sensors in it.
