We’ve all seen glow-in-the-dark t-shirts, little kids shoes that light up when they walk, and even belts with flashing lights on them. But light up teeth? Two designers in Japan are doing just that to advertise a winter sale at their clothing store, Laforet Harajuku.
Now, we’re not just talking about those 25 cent plastic vampire fangs that you can get at Halloween that are supposed to glow in the dark. These “fronts” containing light-emitting diodes (LEDs) that you affix to your teeth and they can glow in different colors when you open your mouth. In fact, they are so bright that you can often see them even with your mouth closed.
Their ad campaign features a group of girls walking around a city in the dark, wearing these LED smiles and acting as if nothing were strange. Frankly, it’s kind of creepy, like a pack of robots slowly coming towards you. The mouthpieces are also a little cumbersome, because you still have to carry a type of battery pack that is attached by wires that hang out of the side of your mouth.
For now, the technology is not commercially available, and the designers, Motoi Ishibashi and Daito Manabe, say they have no plans to make them so at this time. Further testing will have to be done before they can be sold on a large scale, and they will have to prove that the mouthpieces are not harmful to your teeth or general health in any way. Maybe someday you too can have light-up teeth!
