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...
