While not exactly an armor, the name is doing pretty well (not to be guided by the image that does not have much to do). As you know, our teeth need to be brushed at least twice a day, we have to take care and go to the dentist once every six months at least. In other words, the teeth require considerable care. Japan lately seems not so worried about it as it has created a kind of armor to prevent dental cavities annoying.
The enamel on your teeth is mainly composed of hydroxyapatite. Hydroxyapatite is a crystalline form of calcium, and while it is quite hard and durable, can eventually yield to attack bacteria, which are responsible for making a hole and cause cavities. Recently, researchers from Japan's Kinki University have created thin sheets of apatite from 0.004 millimeters thick that can be placed on the tooth to protect. Apparently the person who has not given notice that they are there and can eat, drink and talk normally, with the difference that your teeth are more protected than ever.
Creating these sheets takes much labor is required since the use of lasers and cameras vacuum, among other things. It is hoped that it can give and cosmetic uses for dental treatment over a period of three years and five years respectively.
Anyway, there is a much more effective way to avoid cavities: brush your teeth after each main meal, ie after breakfast, lunch, snack and dinner. Doing this and also brushing our language every day (she also meet in bacteria) can have healthy teeth and manicured without needing any treatment, and of course without having to carry a "dental armor".
