Although sold as a reliable, legitimate diet in certain parts of the world, the diet that has come to be known as the tongue patch diet is in no ways a medically safe procedure, and cannot be called healthy in any sense of the word. I want to speak a few words on the subject, give an idea of what it is, and why it is terrible for your oral cavity. After that, everyone can decide if they want this procedure or not, because it does “help” you lose weight, but at a price that everyone should be informed about.
