The Child Tooth Model (32 Teeth) is a teaching tool specifically designed for biology and dentistry education. It is made according to the actual proportion and arrangement of teeth in the child's mouth, including all 32 baby teeth of the upper and lower jaws. In biology teaching, this model can help students intuitively understand the arrangement order and shape of children's teeth. By observing and learning children's dental models, students can master the anatomical structure, function, and importance of oral hygiene in children. In addition, the model can also be used for teaching demonstrations to help students understand possible problems that may arise during tooth development, as well as basic knowledge of prevention and treatment.
