14 Aug When Baby Teeth Come In and Fall Out? A Parent’s Timeline Guide
Most kids get their first baby teeth around 6 months, and all 20 primary teeth usually arrive by age 2–3. “Normal” covers a wide range, so a few months early or late is common. Lower front teeth tend to appear first, then uppers, then side incisors, first molars, canines, and second molars.
Baby teeth eruption timeline (simple version)
- 6–10 months: lower front incisors
- 8–12 months: upper front incisors
- 9–13 months: side incisors
- 13–19 months: first molars
- 16–22 months: canines
- 25–33 months: second molars
These ranges come from the latest AAPD/ADA resources and are meant to guide you, not stress you.
When do baby teeth start “falling out”?
The tooth loss timeline typically begins around age 6 and wraps up by about 12–13. Front teeth usually loosen first, followed by canines and molars. Meanwhile, the first permanent molars—often called six-year molars—erupt behind the baby molars without replacing any tooth. This stage can be exciting for kids but also a little uncomfortable, as gums may feel tender or slightly swollen. Encouraging gentle wiggling (not forceful pulling) helps teeth fall out naturally and reduces the risk of gum injury or infection. Parents may notice some teeth appearing earlier or later than average, which is often normal but worth discussing with a pediatric dentist if you’re unsure.
Why this timeline matters
Baby teeth aren’t just for chewing—they guide the jaw as it grows, keep space open for permanent teeth, and help kids speak clearly. If a baby tooth is lost too soon from a cavity or accident, nearby teeth can shift and crowd the space, which can make future alignment harder. Regular dental visits let a pediatric dentist check jaw growth, spot early bite problems, and, if needed, use simple tools like space maintainers to keep teeth in place. Caring for these first teeth also teaches kids healthy habits and helps them feel comfortable at the dentist, making future visits easier for everyone.
Brushing, fluoride, and daily care
Start brushing as soon as the first tooth appears. Use a smear (grain-of-rice size) of fluoride toothpaste until age 3, then a pea-sized amount from 3–6. Brush twice daily and help your child spit but not rinse—this keeps a little fluoride on the teeth to fight cavities. Look for the ADA Seal on toothpaste. Red flags parents can watch for
- No eruption by 15 months or very delayed patterns
- Pain, swelling, or a persistent loose tooth before age 4–5
- Spots or pits on teeth (possible early decay)
If you notice any of these, book a visit with a pediatric dentist. The first dental visit is typically by the first birthday or within six months of the first tooth.
Quick reference: falling-out sequence
- 6–7 years: upper/lower central incisors
- 7–8 years: lateral incisors
- 9–12 years: first molars and canines
- 10–12 years: second molars
Bottom line for busy parents
The baby teeth eruption timeline starts near 6 months and the falling out timeline runs from about 6 to 12. Keep brushing with fluoride toothpaste, schedule regular checkups, and expect a little wiggle-and-wait along the way. If something seems off, your pediatric dentist can tell you whether it’s just variation—or needs attention.
