What are baby teeth and why do kids lose them?
The purpose of baby teeth and their natural shedding process
Baby teeth, also known as primary teeth or milk teeth, play a crucial role in a child’s early development. These initial 20 teeth are vital for proper jaw growth, enabling children to chew food effectively and develop clear speech. They also act as placeholders, guiding the eruption of permanent teeth into their correct positions. The natural shedding process of baby teeth is a milestone in development, signifying the transition to a permanent set. This shedding occurs as the roots of the baby teeth gradually dissolve, allowing the underlying permanent teeth to push through the gums.
How many baby teeth do children have?
Children typically develop and have 20 baby teeth. These primary teeth are usually all present by the age of three and are essential for a child’s initial oral health and development. They include incisors, canines, and molars, each serving specific functions in chewing and speech.

Timeline: When do kids lose baby teeth?
The journey of losing baby teeth is a gradual process that begins around the age of 6 or 7. While this is the typical starting point, some children might begin losing teeth as early as 4 or 5 years old, while others may start a bit later. This variability is perfectly normal and depends on individual development.
Stages of baby teeth falling out
The process of losing baby teeth is a natural part of a child’s development and unfolds in stages. Generally, the teeth that appear first are the first to fall out. This usually starts with the lower central incisors, followed by the upper central incisors. As children grow, other baby teeth, including canines and molars, will also loosen and eventually fall out. The first permanent molars (often called six-year molars) erupt behind the baby teeth around age 6, and these do not replace any baby teeth. By the age of 12, children will have lost all 20 of their baby teeth, making way for the permanent set. The last baby teeth to fall out are typically the second molars, which usually happens around ages 10-12.
Understanding permanent teeth development
How many adult teeth do children get?
As children lose their baby teeth, permanent teeth begin to erupt, eventually leading to a full set of 32 adult teeth. This total includes the wisdom teeth, which typically emerge in late adolescence or early adulthood. These permanent teeth are designed to last a lifetime and are crucial for lifelong chewing, speaking, and maintaining facial structure.
The order of tooth loss and permanent tooth eruption
The order in which baby teeth are lost generally mirrors the order in which they first erupted. The process usually begins with the lower central incisors, followed by the upper central incisors. This is then followed by the lateral incisors, first premolars, canines, second premolars, and finally the second and third molars. The eruption of permanent teeth is a carefully orchestrated process, with each new tooth emerging in its designated spot, often guided by the space left by the shed baby teeth.
When to worry about tooth loss or eruption issues
What if my child has extra teeth or late tooth loss?
While the timeline for losing baby teeth is generally predictable, there can be variations. If your child is experiencing late tooth loss or seems to have extra teeth (supernumerary teeth), it’s advisable to consult a dentist. In most cases, these variations are harmless, but in rare instances, they could indicate an underlying dental or systemic issue. Early tooth loss, if it occurs too soon, can also impact the alignment of permanent teeth, so professional assessment is important to ensure proper spacing is maintained. If baby teeth don’t fall out on their own when they should, a dentist might need to intervene, potentially through extraction, to allow the permanent teeth to erupt correctly.
Why dental care is important during tooth loss
Maintaining good oral health throughout the process of losing baby teeth is paramount. As baby teeth fall out, the gums can become sensitive, and the new permanent teeth are more vulnerable to decay. Regular brushing and flossing are essential to keep the gums healthy and prevent cavities in both the remaining baby teeth and the newly erupting permanent teeth. Visiting a dentist regularly for check-ups and cleanings ensures that any potential issues, such as delayed eruption or alignment problems, are identified and addressed early. This proactive approach to dental care not only safeguards your child’s current smile but also lays the foundation for a lifetime of healthy teeth and gums.
