The teeth are coated with a special glaze that protects them from any external aggression. When this layer is gradually disappearing by decalcification, stop protecting them and allowing germs in the mouth that can attack them.
The main culprit of tooth decay is a bacterium called Streptococcus mutans (or S. mutans). This bacterium is transmitted from the saliva of the mother or caregiver to the child during its first 30 months of age and resides in the dentition, so that at least the child must have a tooth so that the actual transfer occurs. The bacteria feed on sucrose and produces acid as a byproduct, thereby degrading the enamel.
