Detailed explanation-1: -Starting with the incisors, baby teeth have flatter biting edges and are typically smaller and more square-shaped. Adult incisors have more rounded biting edges and also erupt with three little ridges on the biting edge. These ridges are called mamelons.
Detailed explanation-2: -They are not growing. In fact, when teeth are developing in the gums as children, they are adult size. As we get into our teen years, the teeth grow into the mouth. It appears that they are growing bigger, but in reality, they are just uncovering themselves from the gum tissue from which they were buried.
Detailed explanation-3: -A disorder characterized as having abnormally small teeth, microdontia can occur in adults and children. Generally, something in one’s genetics tends to pass down microdontia, while other known causes link dwarfism, cleft palate, Down syndrome, and hormonal imbalances to microdontia.
