The first loose tooth can feel like a major event. One child may proudly show the wobble to everyone in the house, while another refuses to touch it and worries that eating dinner will make it fall out.
So, when do kids start losing teeth? Most children lose their first baby tooth at around age 6. The lower front teeth commonly go first, followed by the upper front teeth. From there, the process continues gradually until all 20 primary teeth have usually been replaced by ages 12 or 13.
That timeline is a guide, not a deadline. Some children begin earlier, while others start later. The overall pattern matters more than matching a classmate’s smile exactly.
When Do Kids Start Losing Teeth Normally?
Age 6 is the most common starting point, although some perfectly healthy children may begin around age 5. Children who got their first teeth early as babies may also lose them slightly earlier, while late teethers sometimes begin the process later.
The first loose teeth are usually the lower central incisors, the two small teeth at the center of the bottom jaw. The upper central incisors often follow. Tooth loss may then happen in waves. A child might lose three teeth within several months and then go through a long stretch when nothing seems to change.
Cleveland Clinic recommends speaking with a dental professional if baby teeth begin falling out before age 4 or if a child has not started losing teeth by age 8 or 9. Most differences are harmless, but unusual timing deserves a check.
What Order Do Baby Teeth Usually Fall Out?
Baby teeth often leave in approximately the same order in which they appeared. The front teeth generally go first, while the canines and back molars stay in place longer.
| Baby teeth | Common time to fall out |
| Lower and upper central incisors | Ages 6–7 |
| Lateral incisors | Ages 7–8 |
| Lower canines | Around ages 9–10 |
| First baby molars | Around ages 9–11 |
| Upper canines and second baby molars | Around ages 10–12 |
These ages are approximate. The left and right sides may not follow an identical schedule, and one tooth can remain in place longer than its matching partner.
By the early teenage years, most children have lost all 20 primary teeth. Small variations are expected, but a very uneven or delayed pattern may be worth mentioning at the next dental appointment.
Why Do Baby Teeth Become Loose?
A baby tooth does not simply detach without a reason. A permanent tooth is developing underneath it and gradually moving toward the surface. As the adult tooth advances, the root supporting the baby tooth is absorbed, leaving less structure to hold the crown firmly in place.
Eventually, the tooth may be attached by only a small amount of gum tissue. That is why a naturally ready tooth often comes out with surprisingly little discomfort. It may fall out while the child is eating, brushing, or moving it with their tongue.
Baby teeth may be temporary, but they still support chewing, speech, jaw development, and spacing for permanent teeth. Losing one at the expected time is normal. Losing one too early because of decay or injury can affect the space available for the adult tooth.
What Should Parents Do With a Wiggly Tooth?
Patience is usually the best strategy. Let your child move the tooth gently with a clean finger or their tongue, but do not pull hard while it remains firmly attached. The string-and-doorknob trick belongs in cartoons—not in a child’s mouth.
If the tooth is barely attached and the child wants help, a parent may hold it with clean tissue or gauze and remove it with a gentle, quick twist. Stop if there is resistance or considerable pain. A naturally ready tooth should come out easily.
A small amount of bleeding can occur. Have the child bite gently on clean gauze, and continue brushing the surrounding area carefully. Contact a dentist if bleeding does not stop, the pain is severe, the gum becomes swollen, or part of the tooth appears to remain behind.
Do Six-Year Molars Replace Baby Teeth?
Here is something many parents miss: six-year molars do not replace baby teeth. They erupt behind the last baby molars, often around the same time the lower front teeth begin loosening.
Because no baby tooth falls out first, families sometimes assume these new back teeth are still temporary. They are actually permanent teeth and need to last throughout adulthood. Their deep grooves can collect plaque and food, making thorough brushing especially important.
A dentist may recommend dental sealants for these molars. Sealants are thin protective coatings applied to the chewing surfaces to help protect the grooves from decay. When your child begins losing front teeth, take a quick look at the back of the mouth too. A permanent molar may already be arriving without any Tooth Fairy announcement.
What If an Adult Tooth Appears Behind a Baby Tooth?
Sometimes a permanent tooth erupts behind a baby tooth that has not fallen out, creating two visible rows. Parents often call these “shark teeth.” The sight can be surprising, but it frequently occurs around the lower front teeth during the mixed-dentition stage.
If the baby tooth is already loose, the dentist may recommend giving it time to fall out naturally. The tongue and continued jaw growth may eventually help move the permanent tooth forward. Permanent lower incisors commonly emerge behind the baby teeth before shifting into a better position.
Arrange a dental check if the baby tooth remains firm, the permanent tooth keeps erupting significantly out of position, the area becomes painful, or the double row does not improve. Do not force out a firmly attached baby tooth simply because another tooth is visible.
What If a Baby Tooth Falls Out Too Early?
A naturally loose tooth is different from one lost because of a fall, sports injury, or severe decay. Contact a dentist when a baby tooth is knocked out, even if it would eventually have fallen out on its own. A dentist may need to examine the gums, nearby teeth, jaw, and developing permanent tooth.
Do not attempt to push a knocked-out baby tooth back into its socket. Reimplanting it could damage the permanent tooth developing underneath. A knocked-out permanent tooth, however, is a dental emergency and requires immediate professional instructions.
Premature tooth loss can allow nearby teeth to shift into the empty space. When necessary, a dentist may recommend a space maintainer to preserve enough room for the permanent tooth to erupt correctly.
How Should Children Care for New Permanent Teeth?
New permanent teeth need protection from the day they appear. Help your child brush twice daily for two minutes with fluoride toothpaste and clean between teeth every day. Children of this age may appear independent, but many still miss the gumline, inside surfaces, and back molars.
Partially erupted teeth can be especially difficult to clean because part of the chewing surface may remain covered by gum tissue. Parents should supervise or finish the brushing until the child consistently reaches every area. The American Dental Association recommends twice-daily brushing and daily cleaning between teeth.
Continue regular dental appointments so the dentist can monitor eruption, alignment, cavities, and bite development. Ask whether fluoride treatment or sealants would benefit the new permanent molars. These adult teeth have just arrived, and unlike baby teeth, they do not have natural replacements waiting underneath.
When Should You Contact a Pediatric Dentist?
Contact a dentist if tooth loss is accompanied by severe pain, facial swelling, gum swelling, pus, fever, persistent bleeding, or signs of infection. Dental care is also important after a fall, collision, or other injury that loosens or removes a tooth.
Schedule a non-emergency examination when:
- Baby teeth begin falling out before age 4.
- No teeth are loose by age 8 or 9.
- A permanent tooth does not appear for an unusually long time.
- An adult tooth erupts while the baby tooth remains firmly attached.
- The tooth-loss pattern is very uneven.
- A tooth is lost because of decay or trauma.
Most children who are somewhat early or late are simply following their own developmental schedule. Still, a dentist can use an examination and, when needed, an X-ray to check tooth development, available space, and eruption direction.
Conclusion: When Do Kids Start Losing Teeth?
So, when do kids start losing teeth? Most begin at around age 6, usually with the lower front teeth. The remaining primary teeth generally fall out in stages until ages 12 or 13.
A loose tooth rarely requires dramatic intervention. Gentle wiggling, careful brushing, clean gauze when needed, and a little patience are usually enough. Meanwhile, watch for permanent molars arriving at the back and adult teeth appearing behind loose baby teeth.
Every child’s smile follows its own calendar. A few months of difference is rarely a problem, but significant pain, swelling, injury, unusually early tooth loss, or no loose teeth by age 8 or 9 should prompt a conversation with a dentist.
Frequently Asked Questions
Can a 5-year-old start losing teeth?
Yes. Some healthy children begin losing baby teeth at age 5, particularly if their teeth erupted early during infancy. The lower front teeth usually loosen first. Contact a dentist if tooth loss begins before age 4 or happens because of trauma or decay.
Is it normal for a 7-year-old not to have lost any teeth?
It can be. Some children simply develop later than their classmates. Continue regular dental visits so the permanent teeth can be monitored. If no baby teeth are becoming loose by age 8 or 9, arrange an evaluation.
How long does it take for an adult tooth to come in?
The timing varies considerably. Some permanent teeth appear shortly after a baby tooth falls out, while others take several weeks or months. Contact a dentist if the space remains empty for an unusually long period or nearby teeth begin shifting.
Should a parent pull out a loose baby tooth?
Usually, the child should be allowed to wiggle it naturally. If it is barely attached and comes away without resistance, a parent may help using clean gauze. Never force a tooth that is painful or still firmly connected.
Why does a new adult tooth look more yellow than the baby teeth?
Permanent teeth naturally may appear slightly warmer or more yellow when compared directly with bright white baby teeth. Have a dentist examine the tooth if it has dark patches, unusual white or brown spots, pain, sensitivity, or weak-looking enamel.
