Quick answer: Most children start losing their baby teeth at around 6 years old, although normal timing can vary. The lower and upper front teeth are usually among the first to become loose, and most children continue losing primary teeth through roughly 10–12 years of age. The exact sequence differs from child to child.
Seeing a child’s first loose tooth can be exciting, but it can also raise questions: When do kids start losing teeth? Which teeth fall out first? Is early or late tooth loss normal? Should a loose baby tooth be pulled? This guide explains the typical timeline, what parents can expect, how to care for a child’s mouth during the transition, and when a dentist should check a child’s teeth.
When Do Kids Start Losing Teeth?
Children usually begin losing baby teeth at about 6 years old. This happens as permanent teeth develop underneath the primary teeth and gradually cause the roots of the baby teeth to resorb. Once enough of the baby tooth’s supporting structure has been lost, the tooth becomes loose and eventually falls out.
The process is called shedding of primary teeth and is part of normal dental development. The American Dental Association’s tooth-development chart places the first shedding of the lower and upper central incisors at about 6–7 years, followed by the lateral incisors around 7–8 years. Other primary teeth generally shed later, with canines and second molars commonly being among the last primary teeth to be lost. ADA tooth-development chart.
What Age Do Kids Lose Their Baby Teeth?
A useful general timeline is:
- Around 6–7 years: Lower and upper central incisors commonly begin to shed.
- Around 7–8 years: Lateral incisors commonly follow.
- Around 9–11 years: First primary molars are commonly shed.
- Around 9–12 years: Canines may be lost, with timing varying by the tooth and child.
- Around 10–12 years: Second primary molars are commonly shed.
These are averages, not deadlines. A child may lose a particular tooth somewhat earlier or later and still have normal dental development. The sequence can also differ between the upper and lower jaws.
Which Teeth Fall Out First?
The lower front teeth, or lower central incisors, are often the first baby teeth to become loose and fall out. The upper front teeth commonly follow. These teeth are replaced by permanent incisors.
Parents may notice a small gap after a baby tooth falls out. That gap is usually part of the normal transition from primary to permanent teeth. Permanent teeth are generally larger than baby teeth, so the appearance of the smile can change noticeably during this period.
Why Do Baby Teeth Fall Out?
Baby teeth are designed to serve children during early childhood and then make room for permanent teeth. As a permanent tooth develops beneath a primary tooth, the root of the baby tooth gradually breaks down through a natural process called root resorption. The baby tooth loses its attachment and becomes increasingly mobile.
Eventually, the primary tooth falls out and the permanent tooth can erupt into the available space. This carefully coordinated process is one reason healthy primary teeth remain important even though they are temporary.
What Does a Loose Baby Tooth Feel Like?
A normal loose baby tooth may move slightly when the child touches it with the tongue or finger. Some children notice mild tenderness around the gum, while others have little or no discomfort.
The tooth may become progressively more mobile over days or weeks. A small amount of bleeding when a naturally loose tooth comes out can happen. However, significant bleeding, severe pain, swelling, pus, fever, or an unpleasant taste should not simply be attributed to normal tooth loss.
Should You Pull a Loose Baby Tooth?
In most cases, it is best to let a naturally loose baby tooth fall out on its own. A child can gently wiggle it with a clean finger or tongue if it is comfortable to do so. Avoid forcefully pulling a tooth that is only slightly loose.
If a tooth is extremely loose and bothering the child, a dentist can advise whether removal is appropriate. A tooth that becomes loose because of an injury, severe decay, or another dental problem should also be evaluated rather than treated like an ordinary shedding tooth.
What Happens After a Baby Tooth Falls Out?
After the primary tooth comes out, the permanent replacement tooth may already be visible or may erupt later. A small amount of blood can be normal immediately after a tooth falls out. Have the child bite gently on clean gauze if there is minor bleeding.
Continue normal oral hygiene. The new permanent tooth needs careful protection because permanent teeth are intended to last throughout adulthood.
When Do Permanent Teeth Start Coming In?
Permanent teeth begin erupting around the same general period that children start losing baby teeth. The first permanent molars commonly erupt around 6–7 years, while the lower permanent central incisors commonly erupt around 6–7 years and upper central incisors around 7–8 years. Other permanent teeth follow through childhood and adolescence.
Importantly, the first permanent molars do not replace baby teeth. They erupt behind the primary molars, which is why parents sometimes mistake them for baby teeth.
Is It Normal for Kids to Lose Teeth Early?
Some variation is normal, but a baby tooth that is lost substantially earlier than expected deserves attention, particularly if there was no obvious reason. Early loss can happen because of dental decay, infection, trauma, or other dental-development issues.
If a child loses a primary tooth after an injury or because of significant decay, contact a dentist. Depending on the child’s age, the tooth involved, and the expected eruption of the permanent tooth, the dentist may recommend monitoring or other care.
Is It Normal for Kids to Lose Teeth Late?
Yes, some children lose teeth later than their peers and still have healthy dental development. Family patterns, individual growth, the order in which teeth develop, and other factors can influence timing.
However, persistent asymmetry or a tooth that remains long after the expected stage may need an examination. For example, if one corresponding front tooth has erupted while the other side shows no progress, a dentist can check whether the permanent tooth is developing and erupting normally.
What If a Permanent Tooth Is Coming In Behind a Baby Tooth?
Parents sometimes notice a permanent front tooth appearing behind a baby tooth, creating a temporary double row. This can occur during the transition to permanent teeth and may resolve as the baby tooth loosens and comes out.
If the baby tooth remains firmly in place while the permanent tooth continues to erupt, or if the permanent tooth appears significantly out of position, schedule a dental examination. A dentist can determine whether the tooth needs monitoring or treatment.
How to Care for Kids’ Teeth While They Are Losing Baby Teeth
- Brush twice daily: Use a soft-bristled toothbrush and fluoride toothpaste appropriate for the child’s age.
- Clean between teeth: Help younger children floss or use another age-appropriate interdental cleaner where teeth touch.
- Keep regular dental visits: Routine examinations allow a dentist to monitor eruption, cavities, gum health, and developing bite problems.
- Limit frequent sugary foods and drinks: Frequent exposure to sugar increases the risk of tooth decay.
- Protect permanent teeth: Once permanent molars erupt, ask the dentist whether sealants are appropriate for the child.
- Do not ignore dental injuries: A tooth that becomes loose after a fall, sports injury, or blow to the mouth should be assessed.
The American Dental Association recommends beginning brushing as soon as the first primary tooth erupts and continuing to assist or supervise children until they can reliably manage brushing themselves. citeturn0search11
When Should a Child See a Dentist About a Loose Tooth?
Contact a dentist if a child’s tooth becomes loose because of trauma, is associated with significant pain or swelling, shows signs of infection, or appears to be preventing a permanent tooth from erupting normally.
Children should also have an established dental home early in childhood rather than waiting until baby teeth begin falling out. The American Academy of Pediatric Dentistry recommends establishing a dental home no later than 12 months of age. citeturn0search9turn0search2
When Is Tooth Loss an Emergency?
A naturally loose baby tooth is generally not an emergency. A dental injury can be different. Seek prompt professional care if a child has significant mouth bleeding, facial swelling, severe pain, a serious dental injury, difficulty breathing or swallowing, or a permanent tooth has been knocked out.
Age-by-Age Baby Tooth Loss Chart
| Approximate age | Common dental changes |
|---|---|
| 5–6 years | Some children begin showing early signs of transition, but many still have all primary teeth. |
| 6–7 years | Lower central incisors commonly shed; permanent first molars and lower central incisors may erupt. |
| 7–8 years | Upper and lower lateral incisors commonly shed and permanent incisors continue erupting. |
| 9–10 years | Primary molars and canines may begin transitioning. |
| 10–12 years | Primary canines and second molars commonly shed; permanent teeth continue replacing primary teeth. |
| 12+ years | Most primary teeth have usually been replaced, although individual timing varies. |
Timing is approximate. Children do not all follow exactly the same eruption and shedding schedule.
Frequently Asked Questions
1. When do kids start losing teeth?
Most children start losing baby teeth around age 6. The lower front teeth are often among the first to become loose.
2. What is the youngest age a child can lose a baby tooth?
There is individual variation, but a baby tooth lost substantially earlier than the expected stage, especially without natural loosening, should be discussed with a dentist.
3. What age do kids lose all their baby teeth?
Most children lose their primary teeth during the elementary-school years, with many finishing around 10–12 years, although some variation is normal.
4. Which baby teeth fall out first?
The lower central incisors are commonly among the first baby teeth to shed, followed by the upper front teeth.
5. Does losing baby teeth hurt?
A naturally loosening baby tooth often causes little discomfort, although mild gum tenderness can occur. Severe pain is not typical and should be evaluated.
6. Should I pull my child’s loose tooth?
Usually, no. Let a naturally loose tooth fall out on its own and encourage gentle wiggling if comfortable. Avoid forceful pulling.
7. What if a permanent tooth grows behind a baby tooth?
This can happen temporarily. If the baby tooth does not loosen or the permanent tooth remains significantly out of position, a dentist should examine the child.
8. Can a child lose a baby tooth too early?
Yes. Early loss can be associated with decay, infection, or trauma. A dentist can determine whether monitoring or additional care is needed.
9. When should a child first see a dentist?
The AAPD recommends establishing a dental home no later than 12 months of age, rather than waiting until a child begins losing baby teeth.
10. Do permanent teeth come in immediately after baby teeth fall out?
Not always. A permanent tooth may already be close to erupting, or it may take some time. The timing depends on the tooth and the child’s individual development.
Key Takeaway for Parents
Most kids start losing teeth around age 6, and the process usually continues through about age 10–12. The lower front teeth commonly go first, followed by other incisors, molars, and canines. A little variation is normal, but early tooth loss, significant pain, swelling, injury-related looseness, or delayed eruption should be discussed with a dentist.
Healthy baby teeth still matter. They help children chew and speak, maintain space for permanent teeth, and support normal oral development. Good brushing, fluoride toothpaste, healthy eating habits, regular dental visits, and prompt attention to dental injuries help protect both primary and permanent teeth.
