When Do Kids Lose Baby Teeth? A Complete Age Chart + What Every Santa Rosa Parent Needs to Know

When do kids lose baby teeth is one of the most searched questions among parents of 5 and 6 year olds — and for good reason. One day your child bites into an apple and suddenly announces their tooth feels “wiggly.” What follows is a mix of excitement, uncertainty, and about a dozen questions you were not expecting to have. As Santa Rosa’s kids dentist for children across Sonoma County, Dr. Afnan Choudhry at Toothmate Kids Dental walks parents through this milestone every single week. This guide covers everything: the exact ages, the order teeth fall out, what to do when a tooth gets loose, what to watch for, and when a dental visit becomes important. Save this one — you will come back to it.

When Do Kids Lose Baby Teeth — The Short Answer

Most children begin losing baby teeth around age 5 to 7, starting with the lower front teeth. The process continues gradually through age 12 to 13, when the last baby molars are replaced by permanent adult teeth. By the time this transition is complete, your child will have a full set of 32 permanent teeth (including wisdom teeth that erupt in the late teens).

A few key facts every parent should know up front:

🦷 There are 20 baby teeth in total — 10 upper, 10 lower 🦷 Baby teeth generally fall out in the same order they came in 🦷 Girls tend to lose teeth slightly earlier than boys 🦷 Losing a tooth as early as age 4–5 or as late as age 7–8 can both be completely normal 🦷 A tooth lost before age 4, or no teeth lost by age 8, warrants a dental check-up

The range is wide because every child’s dental development is unique — and that is completely normal. The chart below gives you the average ages by tooth type.

This is the complete baby teeth loss chart showing average ages for each tooth. Remember — your child can be 1–2 years earlier or later and still be perfectly on track. If you have any concerns about your child’s timeline, Dr. Choudhry is happy to review their dental development at their next preventive checkup.

LOWER JAW (Bottom Teeth)

UPPER JAW (Top Teeth)

The lower front teeth are almost always first. The back molars are almost always last. Everything in between follows a general pattern — but individual variation is completely normal.

What Order Do Baby Teeth Fall Out?

Baby teeth fall out in roughly the same order they came in — starting at the front and working toward the back. Here is the typical sequence most children follow:

Stage 1 — Ages 6–7: Lower Front Teeth First The lower central incisors (the two bottom front teeth) are almost universally the first to go. Your child will likely notice one or both of these starting to wiggle around kindergarten or first grade. This is the classic “gap-toothed smile” stage that most parents photograph extensively. The permanent lower central incisors usually erupt quickly after the baby teeth fall out.

Stage 2 — Ages 6–7: Upper Front Teeth Shortly after the lower front teeth, the upper central incisors loosen and fall out. This is when the “shark teeth” phenomenon sometimes occurs — the permanent tooth erupts behind the baby tooth before it has fallen out. This is common and usually self-corrects, but worth mentioning to Dr. Choudhry at the next visit.

Stage 3 — Ages 7–8: Lateral Incisors The teeth immediately beside the front teeth — upper and lower lateral incisors — loosen and fall out next. By age 8, most children have lost their four front teeth on top and bottom and are sporting a distinctive wide smile.

Stage 4 — Ages 9–11: First Molars The first molars — the flat grinding teeth toward the back — loosen and fall out in this window. These are wider teeth and can take longer to fully loosen than front teeth did.

Stage 5 — Ages 9–12: Canines The pointy canine teeth (sometimes called “fangs”) fall out around this time. These teeth have long roots and can feel like they take forever to loosen fully.

Stage 6 — Ages 10–12: Second Molars Last The very back baby teeth — the second molars — are always last to go. Once these fall out, your child’s full permanent dentition (minus wisdom teeth) is in place.

The entire process from first loose tooth to last baby tooth falling out spans approximately 6 to 7 years for most children.

Why Do Kids Lose Baby Teeth — What Is Actually Happening

Understanding the biology makes the whole process less mysterious. Baby teeth are not simply pushed out by permanent teeth — the process is more elegant than that.

As the permanent tooth develops in the jawbone below, it moves upward toward the surface. As it does, it applies gentle pressure to the roots of the baby tooth above it. This pressure signals the body to begin resorbing — literally dissolving — the roots of the baby tooth. As the roots dissolve over weeks and months, the tooth loses its anchor in the jaw and becomes progressively looser. Eventually, only a thin strand of gum tissue holds it in place — and it falls out with minimal effort.

This is why a naturally loose baby tooth has almost no blood when it falls out — the root has already been dissolved away. A baby tooth knocked out by trauma, by contrast, bleeds more because the root is still intact.

It is also why Dr. Choudhry at Toothmate Kids Dental always emphasizes keeping baby teeth healthy even though they are temporary. A baby tooth lost early to decay or injury — before the permanent tooth is ready — leaves a gap that neighboring teeth begin moving into, potentially blocking the permanent tooth’s eruption path. This is exactly the situation that space maintainers are designed to prevent.

My Child Has a Loose Tooth — What Should Parents Do?

A loose tooth is exciting — but parents often have questions about whether to pull it, leave it, or call the dentist. Here is exactly what Dr. Choudhry recommends:

✅ Let it wiggle naturally. Encourage your child to wiggle the loose tooth with their tongue or clean fingers throughout the day. Natural wiggling accelerates the root resorption process and makes the eventual fall-out easier and less traumatic.

✅ Do NOT yank it out early. The “string on the doorknob” method is entertaining in movies but painful and potentially harmful in real life. A tooth pulled before it is ready still has partial roots attached — this causes unnecessary bleeding, pain, and can tear gum tissue. Wait until the tooth is hanging by a thread and comes out with almost no force.

✅ Keep brushing and flossing normally. Do not skip the loose tooth during brushing. The gum area around a loose tooth is vulnerable to plaque buildup and needs normal cleaning just like every other tooth.

✅ When it falls out — stay calm. Have your child bite on clean folded gauze for a few minutes. Any minor bleeding stops quickly. Rinse with water. Avoid hard foods on that side for 24 hours.

✅ Watch for the permanent tooth erupting. The permanent tooth should begin appearing within a few weeks of the baby tooth falling out. If nothing appears within 3 months, a dental check-up is a good idea.

Warning Signs — When Kids Losing Teeth Needs a Dentist Visit

Most baby tooth loss is completely uneventful. But these situations warrant a call to Toothmate Kids Dental at 707-385-1318:

🔴 Tooth falls out before age 4 — early tooth loss is almost always due to trauma or decay, not normal development. A space maintainer evaluation is needed urgently to protect the space.

🔴 No teeth have fallen out by age 8 — while late tooth loss can be normal, it can also indicate delayed permanent tooth development that needs X-ray evaluation.

🔴 “Shark teeth” — permanent tooth erupts behind the baby tooth — this is common and usually self-corrects within a few months as the baby tooth falls out. However, if the baby tooth shows no sign of loosening within 2–3 months of the permanent tooth appearing, Dr. Choudhry may recommend extracting the baby tooth to guide the permanent tooth into proper position.

🔴 Heavy bleeding that does not stop within 15 minutes — this is unusual for a naturally lost baby tooth but warrants prompt dental attention.

🔴 Pain around the loose tooth area — a naturally loose baby tooth should not hurt. Pain may indicate infection in the surrounding gum tissue or an abscess that needs treatment.

🔴 Permanent tooth does not appear within 3 months — the permanent tooth may be impacted or developing in the wrong direction. X-rays at Toothmate Kids Dental can confirm what is happening.

🔴 Knocked-out baby tooth due to an accident — do not reimplant a knocked-out baby tooth (unlike a permanent tooth). Call us to assess the injury, check for root fragments, and discuss space maintenance options.

The “Shark Teeth” Situation — Double Row of Teeth in Children

One of the most alarming things parents discover — and one of the most common questions Dr. Choudhry gets — is the “shark teeth” situation: the permanent tooth appears behind the baby tooth before the baby tooth has fallen out, creating a double row of teeth.

This happens because the permanent tooth grows up and slightly forward — and in some children, it breaks through the gum surface before the baby tooth root has fully dissolved. It looks alarming but is extremely common, particularly with the lower front teeth around ages 6–7.

What usually happens: within 2–3 months of the permanent tooth appearing, the baby tooth loosens and falls out on its own as the permanent tooth’s continued pressure dissolves the remaining root. The permanent tooth then moves forward into the correct position as the tongue pushes it there.

When to act: if the baby tooth has shown no sign of loosening after 2–3 months, or if the permanent tooth appears significantly displaced, Dr. Choudhry may recommend a simple extraction of the baby tooth to guide the permanent tooth to erupt in the right position.

What NOT to do: do not panic. Do not try to wiggle or pull the baby tooth out yourself if it is not yet loose. The vast majority of shark teeth situations resolve completely on their own.

Why Baby Teeth Matter — Even Though They Fall Out

This is the most important section of this entire guide — because Dr. Choudhry hears “why fix it if it’s just going to fall out?” from parents regularly, and it is one of the most consequential misunderstandings in kids dental health.

Baby teeth serve critical functions that directly affect your child’s lifelong dental health:

🦷 Space reservation — baby teeth hold the spaces that permanent teeth need to erupt into. When a baby tooth is lost early to decay or injury, neighboring teeth drift into that space within weeks. When the permanent tooth is ready to erupt months or years later, the space is gone — leading to impaction, crowding, and orthodontic treatment that could have been avoided.

🦷 Chewing and nutrition — children with painful or missing baby teeth avoid hard foods, affecting nutrition during the most critical growth years of their lives.

🦷 Speech development — front teeth are essential for making sounds like “th,” “f,” “v,” and “s.” Early loss of front baby teeth affects speech development in ways that require speech therapy to address.

🦷 Self-esteem — children with visibly decayed or missing teeth face social challenges that affect confidence and school engagement.

🦷 Guiding permanent teeth — baby teeth are literally guides, pointing permanent teeth in the right direction as they develop in the jaw.

This is why Dr. Choudhry recommends treating baby teeth just as seriously as permanent ones — with preventive sealants, fluoride treatment, fillings when needed, and space maintainers when a tooth is lost early.

How to Care for Your Child’s Teeth During the Transition Period

The transition years — ages 6 to 12 — are actually the most important time for preventive dental care, because this is when permanent teeth are erupting and their enamel is at its softest and most vulnerable to cavities.

Dental sealants applied to the chewing surfaces of permanent molars as soon as they erupt provide a protective barrier against decay during the years those teeth are most vulnerable. The first permanent molars erupt around age 6 — the very same time children are losing their first baby teeth. Sealing these teeth promptly is one of the highest-value preventive investments available in children’s dentistry.

Fluoride treatment applied at every preventive checkup actively strengthens newly erupted enamel — giving permanent teeth the best possible start.

Twice-yearly checkups during this period allow Dr. Choudhry to monitor each tooth’s development, catch any crowding or eruption issues early, identify cavities in newly erupted teeth before they become large, and advise on orthodontic referral if needed.

Brushing with fluoride toothpaste twice daily — the AAPD recommends a pea-sized amount for children over 3, and brushing for the full two minutes. Many children this age need a parent to check or finish their brushing — motor skills are not fully developed enough for thorough independent brushing until around age 8.

Frequently Asked Questions — When Do Kids Lose Baby Teeth

When do kids lose baby teeth?

Most children begin losing baby teeth around age 5 to 7, starting with the lower front teeth (central incisors). The process continues through age 12 to 13 when the last baby molars fall out. Girls tend to lose teeth slightly earlier than boys. The range is wide — some children start at 4, others at 8 — and both ends can be completely normal. If your child has lost no teeth by age 8, schedule a checkup with Dr. Choudhry for an X-ray evaluation.

What order do baby teeth fall out?

Baby teeth fall out in the same general order they came in — front first, back last. Lower central incisors first (age 6–7), upper central incisors next (6–7), lateral incisors (7–8), first molars (9–11), canines (9–12), and second molars last (10–12). See the complete baby teeth loss chart in the section above for exact ages by tooth type.

Is it normal for a 5-year-old to lose a baby tooth?

Yes — losing a baby tooth at age 5 is within the normal range, particularly if it is a lower front tooth and it loosened gradually on its own. Some children begin as early as 4. However, if the tooth came out suddenly due to a fall or collision rather than gradually loosening, that is trauma — not normal development — and a dental evaluation and possible space maintainer consultation is needed. Call 707-385-1318.

What do I do when my child’s baby tooth falls out?

When a baby tooth falls out naturally: have your child bite on clean folded gauze for 5–10 minutes to stop any minor bleeding. Rinse the area gently with water. Avoid hard or crunchy foods on that side for 24 hours. Continue normal brushing and flossing. Watch for the permanent tooth to appear within a few weeks to months. If you do not see the permanent tooth within 3 months, schedule a checkup at Toothmate Kids Dental to confirm the permanent tooth is developing correctly.

What if my child loses a baby tooth too early?

If a baby tooth is lost early due to decay or injury — before the permanent tooth is ready to erupt — neighboring teeth can drift into the gap within weeks, blocking the permanent tooth’s path. A space maintainer placed by Dr. Choudhry holds the space open so the permanent tooth can erupt correctly. Contact Toothmate Kids Dental at 707-385-1318 as soon as possible — space maintenance is most effective when placed promptly after early tooth loss.
