One morning, your child tugs on your sleeve with a wiggling front tooth and a look of pure excitement. For many parents, that moment brings just as many questions as it does smiles. When is this supposed to happen? Is it too early? What comes next? Tooth loss is one of the most visible milestones of childhood, and knowing what to expect at each stage can help you feel confident that everything is unfolding on track.
At Kids Dental Center, Dr. Wright and the team guide families through every stage of their child’s oral development, from those very first baby teeth all the way through the full transition to a permanent smile. Here is what you should know about the tooth loss timeline, what drives it, and what to watch for along the way.
When Do Baby Teeth Typically Fall Out?
Most children begin losing their baby teeth around age 6, though some start as early as 5 and others closer to 7. According to the Mayo Clinic, baby teeth typically fall out in the same general order they came in, starting with the lower central incisors and working toward the back of the mouth. By age 13, most children have all of their permanent teeth in place.
Here is a general guide to when baby teeth typically fall out:
- Central incisors (lower front teeth first, then upper): Ages 6 to 7
- Lateral incisors: Ages 7 to 8
- First molars: Ages 9 to 11
- Canines: Ages 9 to 12
- Second molars: Ages 10 to 12
Every child develops at their own pace, so slight variations are completely normal. The full process of losing all 20 baby teeth typically wraps up by around age 12 or 13, though some children finish as early as 10 or as late as 14.
What Causes a Baby Tooth to Fall Out?
Baby teeth do not simply fall out on their own. Beneath the gumline, the permanent tooth is slowly pushing upward. As it does, the root of the baby tooth above it gradually dissolves in a process called root resorption. The root shortens over time until the tooth becomes loose and eventually comes out on its own or with a gentle wiggle.
This is why it is important not to force a tooth that is not ready. A tooth that still has a solid root in place will resist and can be painful to pull. A tooth that has fully resorbed its root comes out easily and with minimal discomfort. Letting the process happen naturally is almost always the right approach.
This is also why routine pediatric dental cleanings and exams are so important during this stage. Regular visits allow Dr. Wright to monitor how permanent teeth are developing below the gumline and catch any early concerns before they become bigger issues. X-rays provide a clear picture of what is happening beneath the surface that a visual exam alone cannot show.
Why Timing Varies Between Children
The timing of tooth loss is influenced by several factors, and understanding them helps parents put their child’s individual timeline in perspective.
Genetics plays a significant role. Children often lose teeth on a timeline similar to their parents’. If a parent lost teeth particularly early or late, their children may follow the same pattern. Overall growth and development can also influence the pace, with children who are above or below average on the general growth curve sometimes trending similarly with tooth development.
Sex is another factor. Girls typically begin losing their baby teeth before boys of the same age, sometimes by several months. This is not a sign of anything unusual, just a consistent difference in developmental timing between the sexes that shows up across many pediatric health milestones.
What If My Child Loses a Tooth Too Early or Too Late?
If your child loses a baby tooth earlier than expected due to decay or an injury, the neighboring teeth may drift into the open space. This can affect how the permanent tooth eventually comes in, sometimes causing crowding or misalignment. In situations like this, a space maintainer may be the right solution to hold that gap open and give the incoming tooth the room it needs to erupt correctly.
On the other end of the spectrum, if your child still has all of their baby teeth well past age 8, it is worth discussing at their next visit. Delayed tooth loss can sometimes point to how the permanent teeth are positioned below the gumline, the presence of extra teeth, or other factors worth evaluating. A pediatric orthodontic evaluation can identify alignment concerns early, when they are typically far easier to address.
Early loss before age 4, or delayed loss beyond age 8 for the first tooth, are both worth bringing up with Dr. Wright at the next scheduled visit. In most cases, a quick x-ray provides a reassuring picture of what is developing below the surface.
The Mixed Dentition Phase
Between roughly ages 6 and 12, children go through what is called the mixed dentition phase, where both baby teeth and permanent teeth are present in the mouth at the same time. This is completely normal and is exactly what the process is supposed to look like. The gaps, the teeth of different sizes, and the slightly uneven appearance of a transitional smile are all part of healthy development.
Parents sometimes worry when a permanent tooth begins to erupt behind a baby tooth that has not yet fallen out. This is sometimes called a shark tooth, because it gives the appearance of a double row of teeth. In many cases the baby tooth falls out on its own within a few weeks as the permanent tooth pushes forward. If the baby tooth is still firmly in place after six to eight weeks, a visit with Dr. Wright can determine whether it needs a simple extraction to clear the way.
Building Healthy Habits as New Teeth Come In
The transition from baby teeth to permanent teeth is a great window of opportunity to strengthen your child’s oral hygiene routine. Permanent teeth need to last a lifetime, so encouraging consistent brushing and flossing as each new tooth arrives is one of the most valuable habits you can build. New permanent teeth are also more susceptible to cavities in their early months, before the enamel has fully hardened, making this a particularly important time to stay on top of cleanings and fluoride treatments.
Good oral health starts well before the first tooth is ever lost. Infant oral health exams lay the groundwork early and give the dental team a baseline to track your child’s development over time. Children who see a dentist consistently throughout childhood tend to feel more comfortable in the chair and more invested in their own oral health as they get older.

Frequently Asked Questions About Losing Baby Teeth
What is the first baby tooth children typically lose?
The lower central incisors, the bottom two front teeth, are usually the first to go, typically between ages 6 and 7. Shortly after, the upper central incisors follow. Baby teeth generally fall out in the same order they came in, starting at the front and working toward the back of the mouth.
Is it normal for my child to still have baby teeth at age 8 or 9?
Yes, many children still have baby teeth at 8 or 9, particularly in the back of the mouth. The first molars and canines are not typically lost until ages 9 to 12. If your child has not yet lost their very first tooth by age 8 or 9, it is worth mentioning at their next dental visit so Dr. Wright can take a look at how the permanent teeth are developing beneath the gumline.
What should I do if my child loses a baby tooth early due to injury or decay?
Early tooth loss can cause neighboring teeth to drift into the open space, which may affect how the incoming permanent tooth erupts. A space maintainer can hold the gap open and protect the alignment of the permanent tooth below. Contact Kids Dental Center for an evaluation if your child loses a baby tooth earlier than expected so Dr. Wright can determine whether a space maintainer is needed.
What is a shark tooth and should I be worried?
A shark tooth is when a permanent tooth begins erupting behind a baby tooth that has not yet fallen out, creating a brief double row of teeth. This is common, especially with the lower front teeth, and usually resolves on its own within a few weeks as the baby tooth loosens. If the baby tooth is still firmly in place after six to eight weeks, a visit with Dr. Wright can determine whether a simple extraction is needed to clear the path.
How can I help my child through the tooth loss process at home?
Let loose teeth wiggle naturally rather than forcing them. A tooth that still has root structure will be painful to pull and should not be forced. Encourage your child to use their tongue or fingers to gently wiggle a very loose tooth until it comes out on its own. Keep up with brushing and flossing even through the gaps, and make sure new permanent teeth are being cleaned thoroughly as they erupt.
