Lost Tooth Chart: A Guide to Baby Teeth and Adult Teeth



As a parent, one of the exciting milestones you’ll witness in your child’s development is the loss of their baby teeth. This significant event, often accompanied by a visit from the tooth fairy, marks the transition from primary teeth to permanent adult teeth. In this comprehensive guide, we will explore the lost tooth chart, understand why we have two sets of teeth, discuss the timeline for tooth eruption and loss, address common concerns, and emphasize the importance of maintaining good dental health for your child.

Lost Tooth Chart: Eruption and Loss Timeline

Each child has their unique timeline for tooth eruption and loss, but there are general patterns to follow. The official term for baby teeth is deciduous teeth, although they are commonly referred to as baby teeth or milk teeth. Your child will have a total of 20 baby teeth before their permanent teeth emerge. Here’s a breakdown of the lost tooth chart:

Tooth Name and Position Eruption Timeline Loss Timeline
Lower central incisors 6 to 10 months 6 to 7 years
Upper central incisors 8 to 12 months 6 to 7 years
Upper lateral incisors 9 to 13 months 7 to 8 years
Lower lateral incisors 10 to 16 months 7 to 8 years
Upper first molars 13 to 19 months 9 to 11 years
Lower first molars 14 to 18 months 9 to 11 years
Upper canines 16 to 22 months 10 to 12 years
Lower canines 17 to 23 months 9 to 12 years
Lower second molars 23 to 31 months 10 to 12 years
Upper second molars 25 to 33 months 10 to 12 years

Why Do We Have Two Sets of Teeth?

Baby teeth serve as placeholders, creating space in the jaw for the future permanent teeth. They allow children to develop proper speech and chewing abilities while their jaws and facial structures grow. The roots of baby teeth begin to dissolve when permanent teeth are ready to erupt. As a result, the baby teeth become loose and fall out, making room for the adult teeth.

The Tooth Eruption and Loss Process

The process of losing baby teeth usually starts around the age of 6. It begins when the root of a baby tooth dissolves completely, making the tooth loose. The tooth is then held in place only by the surrounding gum tissue. Baby teeth are typically lost in the same order they appeared, following the lost tooth chart mentioned earlier.

First Out: Central Incisors

The lower central incisors are the first teeth to appear around 6 months of age, and they are also the first to fall out, usually when a child is around 6 or 7 years old. Following the lower central incisors, the upper central incisors are shed, making way for the permanent teeth that will replace them.

Next Up: Lateral Incisors

After the central incisors, the lateral incisors are the next to go. The upper lateral incisors generally loosen first, typically between the ages of 7 and 8. By this point, your child should be familiar with the process of losing teeth and may find it less intimidating.

Let’s See Those Choppers: Primary First Molars

Losing primary first molars is usually a more comfortable process compared to the discomfort experienced during teething. These molars are shed between the ages of 9 and 11 and are replaced by permanent molars. The primary first molars’ loss marks a significant step in the transition to a full set of permanent teeth.

Final Act: Primary Second Molars and Canines

The canines and primary second molars are the last baby teeth to be shed. Canines are typically lost between the ages of 9 and 12, while the primary second molars are shed between the ages of 10 and 12. By the age of 13, most children should have a complete set of permanent teeth.

Wisdom Teeth: The Encore

During the late teen years, an additional set of molars, known as wisdom teeth or third molars, may emerge. However, it’s important to note that not everyone develops wisdom teeth, and their presence varies among individuals. Wisdom teeth are associated with adulthood and are believed to appear once a person has gained maturity and life experiences.

Deviations from the Timeline

While the provided timeline serves as a general guideline, every child’s dental development is unique. Some children may experience delayed tooth eruption, which can subsequently delay tooth loss. If your child’s dental milestones deviate significantly from the expected timeline, it is advisable to consult with their dentist for further evaluation and guidance.

Dental Visits and Oral Hygiene

Maintaining regular dental visits is essential for your child’s oral health. Schedule your child’s first dental appointment by their first birthday, and continue with biannual visits thereafter. Regular check-ups allow the dentist to monitor tooth development, identify potential issues, and provide appropriate guidance and treatment.

The Tooth Fairy: Celebrating Milestones

Introducing the tooth fairy can make the process of losing baby teeth more enjoyable for your child. The tooth fairy is often associated with leaving a small gift or monetary reward in exchange for the tooth. The amount left by the tooth fairy varies among families, ranging from a few quarters to a few dollars. The first tooth lost usually receives the most generous reward.


The journey of losing baby teeth and welcoming permanent adult teeth is an exciting and important phase in your child’s development. By understanding the lost tooth chart, following the eruption and loss timeline, maintaining good oral hygiene practices, and seeking professional dental care, you can ensure your child’s dental health and pave the way for a lifetime of beautiful smiles.
