Teeth help a person use their mouth to eat, speak, smile and shape their face. Each type of tooth has a name and a specific function. Teeth are made up of different layers -enamel, dentin, pulp and cementum. Enamel, which is the hardest substance in the body, is on the outside of the tooth. The second layer is dentin, which is softer than enamel, and the deepest layer of the tooth is the pulp, which consists of nerves and blood vessels. Cementum is at the root of the tooth and is below the gums. Dental demineralization, also known as premature tooth aging, is a process characterized by the loss of calcium from the tooth. This mineral, which constitutes it, is responsible for giving hardness to the outermost layer of the structure, the tooth enamel. Dental demineralization is a condition that can occur in patients of all ages, whether children or even the elderly. The objective of this work is to review the literature on Dental Enamel Demineralization, emphasizing the etiology, consequences, and reporting how the process occurs, and possible interventions that serve to stop and slow down the process.
