Why Do Baby Teeth Fall Out?
Your child’s baby teeth, also called primary teeth or milk teeth, do much more than help your little one chew their favorite snacks. These 20 temporary teeth guide speech development, maintain proper spacing for adult teeth, and support healthy jaw and facial bone growth.
So why do they eventually fall out? As permanent teeth develop beneath the gums, they gradually dissolve the roots of baby teeth through a process called resorption (essentially, the permanent tooth “eats away” at the baby tooth root). This causes the teeth to loosen and eventually fall out on their own, making way for the larger, stronger permanent adult teeth your child will have for life.
At What Age Do Kids Start to Lose Teeth?
The answer varies significantly among individuals. However, most children begin this process between the ages of 5 and 7. The majority of children lose their first tooth around age 6, but this timeline can differ based on several factors we’ll explore later.
Most children begin losing their baby teeth around age 6. Some children may begin earlier (occasionally as early as 4 years old) or later (up to about 8 years old). If you’re seeing very early exfoliation (before about 4) or marked delays beyond age 8, consult your dentist to rule out underlying causes. Both scenarios can be perfectly normal as long as other developmental markers are on track.
The entire process usually continues until around age 12 or 13, when your child has lost all 20 primary teeth. However, not all permanent teeth will have fully emerged yet. The second molars typically erupt between ages 11 and 13, and wisdom teeth (third molars) emerge much later, if at all.
Which Teeth Fall Out First?
Children generally lose their baby teeth in a similar sequence to how they erupted. Understanding this pattern helps you anticipate what comes next and identify any unusual deviations worth discussing with your child’s dentist.
Lower Central Incisors (Ages 6-7)
The two bottom front teeth are usually the first to become loose and fall out. This milestone often earns your child their first visit from the Tooth Fairy and marks their official entry into the world of being a big kid, complete with a gap-toothed grin.
Upper Central Incisors (Ages 6-7)
Shortly after the lower front teeth, the two top central incisors follow suit, often within the same year. You’ll notice that adorable smile that’s so characteristic of first graders as these baby teeth fall out.
Lateral Incisors (Ages 7-8)
The teeth positioned beside the central incisors on both the upper and lower jaws are next in line. These lateral incisors help with biting and tearing food as your child tackles increasingly complex meals.
First Molars (Ages 9-11)
These larger back teeth, used primarily for grinding food, come out during the elementary school years. Although timing varies, they’re often referred to as the “nine-year molars” when discussing their loss.
Canines (Ages 9-12)
The pointed teeth next to the lateral incisors typically fall out between the ages of 9 and 12. Also called cuspids or “eye teeth,” these play an important role in maintaining proper jaw development and helping your child bite into foods.
Second Molars (Ages 10-12)
These are generally the last baby teeth to fall out. The second molars may remain until age 13 or occasionally age 14 in some children.
Important note: While this pattern is common, variations in sequence are normal and not necessarily concerning. Focus on monitoring overall progression rather than fixating on exact timing or order. Some kids lose teeth in clusters, while others lose them more gradually; both approaches are standard.
At What Age Do Kids Lose Their Teeth? Understanding Individual Timelines
Several elements affect when your child will lose their teeth, making each child’s experience unique. Understanding these factors can help alleviate your concerns if your child’s timeline doesn’t align exactly with their peers.
Genetics
Family history plays the most significant role in dental development. If you or your partner lost teeth early or late in life, your children are likely to follow a similar pattern. This hereditary influence extends to both the timing and sequence of tooth loss, so reviewing your own childhood dental history can provide valuable insights into what to expect.
Individual Development Patterns
Each child’s growth trajectory differs, affecting when their teeth become loose. Children who lose their first baby teeth early, like at 4-5 months instead of 6-7 months, often start losing their baby teeth earlier, potentially beginning as early as 4 years old. Conversely, late teethers may not lose their first tooth until they are 8 years old or older.
Nutrition and Overall Health
A balanced diet rich in calcium, vitamin D, and other essential nutrients supports healthy tooth development and may influence when kids start losing their baby teeth. Proper nutrition ensures a strong tooth structure and healthy gum tissue, which facilitates the transition from primary to permanent teeth.
Dental Health and Hygiene
Regular brushing and flossing promote overall dental health and contribute to a smoother transition. However, untreated tooth decay can cause premature loss of baby teeth, disrupting the expected progression. Cavities that weaken tooth structure sometimes cause teeth to fall out before the permanent teeth beneath are ready to emerge.
What Are the Signs Your Child Is About to Lose a Tooth?
You can usually spot several indicators before a tooth actually falls out:
- Visible wiggling – The most obvious sign; many children enjoy playing with the loose tooth using their tongue or fingers
- Gaps appearing – Spaces may develop around the tooth as it loosens and the gum tissue changes
- Gum tenderness – The gums around the loose tooth may appear slightly red or swollen
- Mild discomfort – Some children report slight sensitivity or pressure as the permanent teeth push up from below
- Minor bleeding – A small amount of blood when the tooth wiggles is expected due to irritation
A loose tooth can take anywhere from a few weeks to several months to fully loosen before it falls out. This gradual process minimizes discomfort and allows the permanent teeth to develop properly beneath. Most kids find the wiggling sensation more interesting than painful.
When Should You Be Concerned About Early Tooth Loss?
Losing a baby tooth before age 4 or 5 without an apparent cause, such as an injury, may indicate an underlying issue and warrants evaluation by your child’s dentist.
Common Causes of Premature Tooth Loss
- Dental trauma – Falls, sports injuries, or accidents that knock a tooth out prematurely
- Tooth decay – Untreated cavities severely weakening tooth structure and causing early loss
- Gum disease – Periodontal problems affecting the tissue that supports teeth in the mouth
- Genetic conditions – Certain inherited disorders affecting normal tooth development
- Systemic health issues – Rare diseases that impact oral health and dental development
Why Early Loss Matters
Premature baby tooth loss can lead to several complications:
- Adjacent teeth may shift into the empty space, causing crowding when permanent teeth emerge
- Disrupted positioning can create alignment issues requiring orthodontic treatment
- Missing front teeth may temporarily affect speech and pronunciation
- Losing multiple teeth can make eating difficult and impact nutrition
- The new adult teeth may not have enough room to emerge properly
If your child loses a tooth before the usual age, consult a pediatric dentist or dental professional promptly. If premature primary tooth loss occurs, your dentist may recommend a space maintainer depending on the specific situation. These devices are small, comfortable, and help preserve room for the permanent tooth to emerge properly, preventing future crowding and misalignment.
Is Late Tooth Loss a Problem?
If your child hasn’t lost any teeth by age 8, or if a specific tooth remains firmly in place past age 13, professional evaluation is advisable. While delayed tooth loss isn’t always problematic, it’s important to rule out potential issues.
Possible Causes of Delayed Tooth Loss
Several factors can delay the natural progression:
- Ankylosis – The baby tooth root fuses directly with the jawbone, preventing natural loosening. Ankylosis is relatively uncommon but well-documented; reported rates vary substantially between studies, so diagnosis and management are individualized.
- Impacted permanent teeth – The adult tooth may be blocked by bone, soft tissue, or positioned incorrectly
- Congenitally missing teeth – In rare cases, the permanent tooth simply doesn’t exist
- Crowding issues – Insufficient space may prevent permanent teeth from developing enough pressure to push out baby teeth
- Medical conditions – Certain hormonal or endocrine disorders can delay normal development
What Are “Shark Teeth”?
One common scenario is “shark teeth,” where permanent teeth erupt behind baby teeth that haven’t fallen out yet. This creates a temporary double row of teeth in your child’s mouth that often concerns parents.
In many cases, the baby tooth simply needs additional time (and gentle encouragement from your child to wiggle it) to fall out naturally. The tongue will help guide the permanent tooth forward into its proper position once the baby tooth is gone. In many cases, you can wait 2-3 weeks to see if the baby tooth loosens further. However, contact your dentist sooner if you experience pain, swelling, signs of infection, persistent bleeding, or difficulty eating.
When is intervention needed?
If the baby tooth remains stubbornly in place for several weeks while the permanent tooth continues erupting behind it, your child’s dentist may recommend extraction. This prevents alignment problems and ensures your child’s permanent teeth can move into their correct positions. Modern extraction techniques ensure your child experiences minimal pain during the procedure.
