Even minor dietary mistakes can lead to dental decay. The consequences are often severe: toxic dental materials like amalgam, bacterial foci in dead teeth and in the jaw gradually result in a loss of well-being, health, and vitality. Only with healthy teeth and a focus-free dentition can a tolerable age be reached. Unfortunately, many only recognize the value of a healthy dentition when expensive treatments are necessary, teeth need to be extracted, and dental prosthetics cause problems. This book shows how dental decay can be prevented and what to pay attention to so that children develop a beautiful dentition without cavities. It also warns against misguided concepts for cavity prevention that involve highly toxic fluorides. Fluoride accumulation in the body is irreversible, and the resulting diseases are incurable.
