The reasons why teeth become transparent are as follows: 1, enamel is basically transparent or translucent, it is the hardest material in the outermost layer of teeth, which mainly plays the role of helping teeth to bite off hard food and protecting teeth. However, if the teeth are not well protected, the enamel will be damaged, such as the calcification and corrosion of the enamel is also the reason why the teeth become transparent; 2, the teeth are transparent is caused by mild dental caries, this situation should go directly to the dental treatment; 3, the teeth become transparent maybe because the body contains too much iron, because the iron in the body will leave pigmentation on the teeth of the human body, also This situation is not the problem of teeth itself, so don’t pay special attention to it, just pay attention to oral hygiene and avoid biting hard objects.
