Baby teeth, also known as primary teeth or deciduous teeth, are a fascinating part of human development. These tiny teeth serve a crucial purpose in our lives before they fall out and make way for permanent teeth. In this article, we will explore what baby teeth are, when they come in, why they fall out, and how many baby teeth we have.

What Are Baby Teeth?

Baby teeth are the first set of teeth that humans get, usually starting to appear between 6 and 12 months of age. These teeth are not as big or sturdy as permanent teeth but are just right for the infant mouth. They are usually whiter and more translucent than adult teeth, with smaller roots.

Baby teeth are crucial to the development of the child’s mouth and jaw. Without these teeth in place, children would have a hard time learning how to chew and form words properly. Baby teeth also serve as a guide for adult teeth, ensuring they grow in straight and correctly aligned.

When Do Baby Teeth Come In?

The first baby teeth to come in are usually the two bottom front teeth, followed by the two top front teeth. These teeth are known as central incisors and usually appear between 6 and 10 months of age. The next four teeth to appear are the lateral incisors, one on each side of the central incisors. These teeth appear between 9 and 16 months of age.

After the incisors, the first molars appear between 12 and 16 months, followed by the canines (also known as cuspids) between 16 and 23 months. Finally, the second molars come in between 23 and 33 months of age.

Why Do Baby Teeth Fall Out?

Baby teeth fall out to make way for permanent teeth. As the child’s jaw and mouth grow, the smaller baby teeth become too small and are replaced by larger, stronger permanent teeth. A child’s first permanent teeth, the molars, usually appear around age 6.

This process of losing baby teeth and replacing them with permanent teeth might seem like a simple one, but there’s more to it than meets the eye. Baby teeth actually play a significant role in the development of adult teeth and the jawbone. They help maintain optimal spacing and room for the eruption of permanent teeth. Tooth loss at an early age can result in crowded, misaligned, and crooked teeth, which may require orthodontic treatment later in life.

How Many Baby Teeth Are There?

Most children have 20 baby teeth, ten on the top, and ten on the bottom. This includes four front teeth (central and lateral incisors) and eight back teeth (molars and canines). As mentioned earlier, these teeth serve as a guide for permanent teeth to erupt into the correct positions later in life.

In rare cases, some children might have extra or missing baby teeth. In some instances, temporary teeth might not fall out, which can lead to dental crowding and other complications. Conversely, missing baby teeth might not allow permanent teeth to grow properly, leading to gaps and improper spacing.
