Baby teeth, also known as primary teeth or deciduous teeth, are the first set of teeth that develop in children. They usually begin to emerge around six months of age and continue to come in until about three years old. There are typically 20 baby teeth, which help children chew food and speak clearly. These teeth eventually fall out to make way for permanent teeth, which start to appear around age six. The process of losing baby teeth usually continues until around age twelve or thirteen. Proper care of baby teeth is important for overall dental health and can influence the alignment of permanent teeth.
