As a parent, witnessing your child’s first smile, first words, and first steps are among life’s precious moments. Another milestone that marks their growth is the transition from baby teeth to permanent teeth. This process, while natural, often prompts questions like, “How long does it take for baby teeth to fall out?” Understanding this timeline can help ease concerns and guide you through this developmental phase.

Typically, children start getting their baby teeth, also known as primary teeth, around 6 months of age. By the age of 3, most children have a full set of 20 primary teeth, which serve crucial roles in chewing, speaking, and guiding permanent teeth into place.

If you have questions about this phase, our Humble, TX dentists are here to help! 

How And When Baby Teeth Fall Out

The process of baby teeth falling out, also called exfoliation, usually begins around the age of 6 or 7. However, it’s essential to remember that every child is different, and the timing can vary. Some children might start losing their teeth as early as 4 or as late as 8 years old. Factors such as genetics, dental hygiene, and overall health can influence this timeline.

The sequence of tooth loss typically follows the order in which the teeth erupted. The lower front teeth (lower central incisors) are usually the first to go, followed by the upper front teeth (upper central incisors). This pattern continues, with the primary molars and canines falling out before the back molars.

The process of a baby tooth falling out usually begins when the permanent tooth beneath it starts to push against the roots of the primary tooth. As the roots dissolve, the baby tooth becomes loose and eventually falls out. In some cases, children might experience discomfort or mild pain as the tooth loosens, but this is usually temporary and manageable with gentle care.


Once a baby tooth falls out, it’s essential to encourage good oral hygiene habits to prevent any complications. Remind your child to brush their teeth twice a day with fluoride toothpaste and to floss daily. Regular dental check-ups are also crucial for monitoring the transition from primary to permanent teeth and addressing any concerns that may arise.

The Third Molars

The process of exfoliation typically continues until the age of 12 or 13, by which time most children have their full set of permanent teeth. However, the last teeth to erupt are the third molars, commonly known as wisdom teeth, which usually appear between the ages of 17 and 25.

Intervention, Delays, and Deviations

While the timeline for baby teeth falling out is generally predictable, there can be instances where intervention is necessary. If a baby tooth is severely decayed or damaged, it may need to be extracted to prevent infection or alignment issues with the permanent teeth. In such cases, your dentist will discuss the best course of action to ensure the health and well-being of your child’s smile.

It’s also worth noting that some children may experience delays or deviations from the typical tooth loss timeline due to various factors such as dental anomalies, medical conditions, or trauma. If you have any concerns about your child’s dental development, don’t hesitate to consult with a trusted dentist who can provide expert guidance and personalized care.
