The Cavity Zapper
|
|
By 2021, the Cavity Zapper is going to find the cavity before it happens. It always cleans the
teeth perfectly and never lets you miss a spot. It will be as light and easy to use as an old- fashioned toothbrush, only it will have a sensor on the end of each bristle so you don't miss a single germ. |
|
The bristles will be made of fiber optic plastic, which means they will reflect light like a camera.
|
|
When the bad, cavity causing bacteria are detected by the Cavity Zapper's sensors, the bacteria
will make sort of a pattern or a picture that can be read with a laser. The sensors ignore all the good bacteria in your mouth, but the harmful bacteria will show up as a flashing red light on a little scrteen that plugs into an outlet on your bathroom wall. The Cavity Zapper will plug into the screen. |
|
The whole thing could work
like the UPC bar code scanner used in libraries and grocery stores. |
|
A grown-up would then help you use Cavity Zapper antibiotic toothpaste or antibiotic floss, just
exactly on the spot where the harmful bacteria are before they've had a chance to destroy your tooth enamel. |
|
Maybe the floss and toothpaste could come together in a pack. And ZAP! The cavity didn't
even stand a chance. You can even go back and check on the screen to be sure you got everything. |
|
Detection should take about a second. The whole thing-- brushing, detection, and treatment--
should take about three minutes. |

Science Note: Phototonics all
started with Albert Einstein. He wrote a paper explaining that light is really made of photons. Each photon has its own energy that we can use in different ways. Einstein won a Noble Prize. |
