In spite of the fact we regularly brush our teeth, it doesn't save them from decaying and caries appearing. That's why my idea, supposed to decide this problem, is to invent a special tooth-paste with a long-lasting effect. The principle of such paste would be appearing special superfine layer on teeth surface that would defend our teeth from bacteria impact with long-lasting effect. Having brushed your tooth one time a half of a year, you would be protected for a long time. The superfine layer would be later removed by a dentist and later you would be able to apply the defensive layer again.
I think the idea is possible, taking into account great developments in the field of chemistry!
It would come a real salvation of our teeth state!!!
