Kids Losing Teeth - What Parents Need to Know

Published - April 2025 Last Updated - April 2026

The first wobbly tooth is a big moment. For children, it means the tooth fairy is coming. For parents, it raises a string of questions. Is this the right time? Should we pull it? What if the adult tooth comes in crooked?

Kids losing teeth is completely normal, and it follows a predictable pattern. This guide covers the timeline, what to expect, and when to act.

When do children lose teeth? - The Typical Timeline Ages 5–12

Most kids begin shedding their first baby tooth between five and seven years old, with the process typically kicking off around age six. According to the Cleveland Clinic's pediatric dentist, Dr. Daniel Gindi, some children lose their first tooth as early as 4.5, and some don't lose any until they're 8. Both ends of the range are normal.

By the early teens, most children have lost all 20 baby teeth. The full transition takes about 5 to 7 years.

General Timeline

Girls tend to lose teeth slightly earlier than boys. Don't panic if your child is a few months outside this range;  that's entirely normal.

When to see a dentist - If your child has lost no teeth by age 8, or loses their first tooth before age 4, it's worth a dental check-up. Both can be normal, but a dentist can confirm there are no underlying issues.

The Order Kids Lose Teeth - Which Comes First and Why

Teeth tend to loosen and fall out following the same sequence in which they originally erupted. Bottom front teeth first, top front teeth second, then outward toward the back.

This isn't random. Each baby tooth acts as a guide for the permanent tooth growing beneath it. The adult tooth pushes up, loosens the root of the baby tooth, and the baby tooth falls out.

Dr. Travis Nelson, Clinical Associate Professor and Chair of Pediatric Dentistry at the University of Washington, puts it simply: " tooth loss begins with the lower front teeth and progresses to the baby second molars falling out last."

Girls may move through this sequence slightly faster than boys. This is consistent across most dental research.

Helping a Wobbly Tooth - When to Wiggle and When to Leave Alone

Once a tooth gets wobbly, children usually can't stop touching it. That's fine.

Gentle wiggling with a clean finger or tongue is encouraged. Dr. Daniel Gindi from the Cleveland Clinic explains that children who don't wiggle their loose teeth sometimes develop inflammation or overgrown gums around them. 

If a baby tooth remains too long, the gum can tighten around it, making it more difficult for the permanent tooth to emerge.

What to Do?

• Let your child wiggle with their tongue or a clean finger
• The tooth will usually come out on its own while eating or playing
• Some light bleeding is normal when the tooth falls out
• Have your child rinse with water and apply gentle pressure with a clean cloth

What Not to Do

• Don't yank it out with a string or force - this can damage gum tissue
• Don't pull a tooth that barely wobbles - it's not ready
• Don't ignore a tooth that's been wobbly for several months with no movement

If a tooth has been wobbly for more than 3 months with no change, see a dentist.

When a Tooth Is Knocked Out - What to Do Immediately

A knocked-out tooth is a dental emergency. The response in the first 30 minutes matters.

Step-by-Step: Knocked-Out Permanent Tooth

1.   Pick up the tooth with the crown (white part), not the root

2.   Rinse gently with milk or saline, not water, not soap

3.   Try to reinsert it into the socket and hold it gently in place

4.   If reinsertion isn't possible, place the tooth in milk or have the child hold it between their cheek and gum

5.   Get to the dentist within 30 minutes; the sooner, the better

Important distinction - A knocked-out baby tooth should not be reinserted. Reinserting a baby tooth can damage the developing adult tooth underneath. If a baby tooth is knocked out, go to the dentist for assessment, but do not attempt reinsertion.

If a tooth is knocked out from a fall or injury, whether baby or permanent, see a dentist that day.

Dental Care During the Mixed Dentition Phase

The period when children have a mixture of baby and adult teeth, roughly ages 6 to 12, is called the mixed dentition phase. It's one of the most important windows for dental health.

Why It Matters?

Baby teeth guide adult teeth. If a baby tooth is lost too early (from decay or injury), the surrounding teeth can shift. This can block or misalign the incoming adult tooth.

Dental decay in baby teeth still causes actual pain and can affect the development of adult teeth underneath. According to guidance from the American Academy of Pediatric Dentistry.

• Brushing twice daily with fluoride toothpaste
• Flossing daily, yes, even baby teeth
• Dental check-ups every 6 months

Children often need supervision with brushing until the ages of 7–8. Their manual dexterity isn't reliable enough before then to clean teeth thoroughly on their own.

One Practical Tip

Check the brushing. Children at this age often rush and skip areas. A quick "brush check" after they've finished, with a gentle word, not a lecture, catches the gaps before they become cavities.

Orthodontic Concerns - When to See an Orthodontist

Most children don't need an orthodontist before all their adult teeth have come in. But some situations warrant an earlier referral.

Seeing an Orthodontist If You Notice

• Significant overcrowding of adult teeth coming in with no space
• A permanent tooth erupting behind the baby tooth (double row of teeth)
• An adult tooth that's come in noticeably crooked
• An underbite or crossbite is developing
• A jaw that seems misaligned when the mouth is closed

The American Association of Orthodontists recommends an initial orthodontic evaluation no later than age 7. This doesn't mean treatment starts at 7; it means the orthodontist can identify problems early and plan the right time to act.

Most children who need braces begin treatment between the ages of 11 and 14 after most adult teeth have come in.

Don't be alarmed by temporary crookedness. When adult teeth first come in, they often look noticeably large and slightly crooked compared to the smaller teeth around them. In many cases, this self-corrects as the jaw grows and more adult teeth emerge. Wait and watch, don't panic at the first slightly tilted incisor.

Kids Losing Teeth -The Bigger Picture

Kids losing teeth is one of the most consistent milestones of childhood. It follows a predictable pattern, causes minimal discomfort in most cases, and takes care of itself.

Your job is to:

• Keep up with dental hygiene through the transition
• Watch for anything that seems significantly early, late, or painful
• Make the tooth fairy visit something worth looking forward to

And if your child is 6, walking around with a wobbly front tooth and a huge grin about it, that's exactly what's supposed to be happening.

Frequently Asked Questions

When do kids start losing teeth?

Most kids start losing their first baby tooth sometime between the ages of five and seven. The bottom front teeth usually go first. Some children lose teeth as early as 4.5 or as late as 8;  both can be normal.

In what order do kids lose their teeth?

Bottom front teeth first, then top front teeth, then lateral incisors, then canines and first molars, and finally the second molars around ages 10–12. Teeth fall out in the same order they came in.

Should I help wiggle my child's loose teeth out?

Gentle wiggling with a clean finger is fine. Do not yank or force a tooth that isn't ready. Most teeth come out naturally while eating or playing. If a tooth has wobbled for more than 3 months without falling out, see a dentist.

What should I do if my child's tooth is knocked out?

 If it is a permanent tooth, rinse it gently with milk and try to reinsert it. If that's not possible, store it in milk and get to the dentist within 30 minutes. Do not reinsert a knocked-out baby tooth; see a dentist for assessment instead.

When should I take my child to an orthodontist?

The American Association of Orthodontists recommends an initial evaluation by age 7. This doesn't mean treatment starts then; it allows early identification of issues that may need planning.

Is it normal for adult teeth to look crooked at first?

Often, yes. Adult teeth look large and slightly tilted when they first come in. Many cases self-correct as the jaw grows and more adult teeth emerge. However, if you see significant crowding or misalignment, consult a dentist.
