Before worrying, parents need to clearly understand how the natural tooth replacement process works in children. This is a pre-programmed biological process designed to prepare a strong and stable set of permanent teeth in the future.
1. When do baby teeth start to loosen and fall out?
Typically, a child’s tooth replacement journey begins between the ages of 5 and 7 and can continue until around 12 to 13 years old. This process does not happen all at once but follows a fairly predictable sequence, usually starting with the two lower front teeth.
As the permanent tooth buds beneath develop and erupt, they apply pressure to the roots of the baby teeth. All 20 baby teeth are gradually replaced over many years, making this a long developmental phase rather than a single event.
2. Why is a loose baby tooth a “happy milestone”?
This is a positive sign that the permanent tooth buds underneath are developing well and are ready to take over. The pressure from the erupting permanent teeth causes the roots of the baby teeth to gradually resorb, a completely natural biological process.
Once the roots have almost fully resorbed, the baby tooth loses its support, becomes loose, and eventually falls out easily, usually without pain. This process ensures that the permanent tooth has a clear and correct path to erupt into position.
The role of baby teeth goes beyond chewing. They also guide the future smile. Daily chewing with baby teeth stimulates balanced jawbone development, creating a solid foundation for permanent teeth.
Therefore, the issue is not simply “this tooth needs to fall out,” but rather “this tooth needs to fall out at the right time” to ensure adequate space and proper jaw development for permanent teeth.
Sometimes, the natural tooth replacement process encounters “problems.” If a baby tooth remains loose for a long time without falling out, it may be due to one of the following reasons:
1. Permanent tooth “loses its way” – Erupts in the wrong position
The permanent tooth does not erupt directly beneath the baby tooth but instead grows inward or outward.
This condition is often referred to as “shark teeth,” as it creates the appearance of two parallel rows of teeth. When the permanent tooth erupts off-axis, it does not apply sufficient pressure to the baby tooth root, preventing proper root resorption. As a result, the baby tooth remains firmly in place while the permanent tooth finds an alternative path, leading to significant misalignment.
2. The baby tooth root is “stubborn” and has not fully resorbed
Although the tooth is loose, part of the root is still firmly attached to the gum.
In some cases, despite pressure from the permanent tooth, root resorption remains incomplete. The remaining root acts like a stubborn anchor. Attempting to pull a tooth when a significant portion of the root is still present can cause pain and carries the risk of root fracture, leaving fragments embedded in the gum.
3. Swollen gums or soft tissue “holding on” to the tooth
Gingivitis or overly thick gum tissue can grip the tooth tightly and prevent it from falling out.
Gum inflammation caused by poor oral hygiene can lead to swelling, causing the gums to tightly surround the tooth neck. Additionally, thick or fibrotic gum tissue may create a physical barrier, preventing the tooth from falling out even when the root has mostly resorbed.
4. Eating habits and chewing force are “not enough”
An overly soft diet does not provide sufficient force for the tooth to fall out naturally.
Mechanical chewing activity from firmer foods (such as apples or carrots) helps further loosen the tooth and promotes natural exfoliation. A diet consisting mainly of soft foods like porridge, soup, and yogurt does not provide this necessary force. This highlights the direct relationship between diet and the tooth replacement process in children.
The tooth has been loose for too long: If the tooth has been noticeably loose for more than 2–3 months without falling out, it may indicate that the natural process has stalled.
The permanent tooth has already erupted: The appearance of a permanent tooth, especially in “shark tooth” cases, is a clear signal that intervention is needed. Delaying treatment may worsen misalignment.
Pain and discomfort: If the loose tooth causes persistent pain, interferes with eating, or leads to gum inflammation, extraction can significantly improve your child’s quality of life.
The baby tooth obstructs the new tooth: If the baby tooth blocks or redirects the eruption path of the permanent tooth, removal is necessary to “clear the way” for proper alignment.
These signs indicate that professional intervention is needed. Delaying treatment may lead to more complex problems later. Parents should take their child to a reputable dental clinic for safe and gentle baby tooth extraction, helping pave the way for a healthy future smile.

Sometimes, patience is the best solution for your child’s smile.
1. Misaligned and crowded permanent teeth lead to future orthodontic burden
When baby teeth do not fall out on time, permanent teeth are forced to erupt in limited space, causing crowding and misalignment. This initial disruption can spread like a domino effect, affecting the entire dental arch.
As a result, the child may require orthodontic treatment later, a process that is costly in both time and money. Early and timely intervention can help avoid this burden.
2. Bite misalignment affects aesthetics and chewing function
Misaligned teeth prevent proper occlusion, leading to bite problems. This reduces chewing efficiency, affects digestion, and disrupts balanced facial development. Over time, malocclusion can also cause tooth wear and jawbone deformities.
3. Increased risk of cavities and spreading infection
Baby teeth that remain too long are more prone to bacterial buildup, especially if decay is present. These bacteria can spread to newly erupted permanent teeth, causing damage at an early stage when the teeth are still weak and sensitive.
4. Pain and psychological impact on the child
Prolonged tooth looseness causes discomfort, while misaligned or “shark teeth” can make children feel self-conscious when smiling or speaking. Beyond aesthetics, speech development and self-confidence may be significantly affected.
Conclusion: In summary, a baby tooth that stays loose for a long time is not always a cause for alarm. However, when signs such as prolonged looseness, pain, or the eruption of permanent teeth appear, consulting a dentist becomes essential. Parents should be attentive and proactive companions in caring for their child’s smile.
Extracting baby teeth at the right time is crucial to protecting your child’s future smile. On the other hand, intervening too early also carries its own risks. To learn more, parents can read our next article: Does Early Baby Tooth Extraction Affect Permanent Teeth?
