When Do Babies Start First Tooth?

The first tooth is a milestone that arrives with great fanfare — often preceded by drooling, fussiness, and sleepless nights. Most babies get their first tooth (usually a lower central incisor) between 6-10 months, though perfectly healthy babies can teethe as early as 4 months or as late as 12+ months.

👀 Signs Your Baby Is Ready

✅
Increased drooling that may start weeks before a tooth appears
✅
Swollen, red gums where the tooth is pushing through
✅
Increased biting and chewing on everything
✅
Mild fussiness, especially in the evenings
✅
Pulling at ears or rubbing cheeks (referred pain)
✅
Slight decrease in appetite

🎾 Ways to Encourage First Tooth

Try these activities to support your baby's development:

Chilled teething rings

Cold numbs gums and biting provides counter-pressure relief — chill in fridge, never freeze

Clean wet washcloth

Place a clean, damp washcloth in the fridge for 30 minutes, then let baby chew on it

Gum massage

Gently rub baby's gums with a clean finger — the pressure provides relief

Start oral care immediately

Begin brushing with a soft infant toothbrush and rice-grain-sized smear of fluoride toothpaste as soon as the first tooth appears

⚠️ When to Talk to Your Pediatrician

  • ⚠️ No teeth by 18 months — consult a pediatric dentist
  • ⚠️ Teeth erupting discolored (brown, yellow, or white spots)
  • ⚠️ Fever over 100.4°F — teething does NOT cause true fever
  • ⚠️ Persistent diarrhea or rash (not caused by teething)
  • ⚠️ Natal teeth present at birth (consult your pediatrician)

About Physical Development Milestones

Physical development milestones track overall bodily growth and coordination as it relates to a baby's size, strength, and stamina, distinct from the more specific skill-based gross and fine motor categories. These milestones are closely tied to nutrition and overall health, since adequate calories and nutrients directly support the muscle and bone development physical milestones depend on. Because physical development varies with individual growth patterns (a naturally larger or smaller baby may reach certain physical milestones on a different timeline), it's generally interpreted alongside a baby's individual growth chart rather than compared to a single fixed age target.

How to Read Milestone Age Ranges

Milestone age ranges (like "3 to 5 months" for rolling over) reflect the spread of ages at which most typically developing children reach that skill, based on large reference populations tracked by organizations like the CDC and WHO. A baby who reaches a milestone at the early end of the range isn't necessarily "ahead," and a baby who reaches it at the later end isn't necessarily "behind" — both are within the expected range of normal development. What tends to matter more to pediatricians than the exact timing of any single milestone is whether a baby is generally progressing across all developmental domains over time, and whether they show any of the more specific red-flag signs associated with a particular skill. If a baby falls outside the typical range for a milestone, especially by a significant margin, that's a reasonable prompt to raise the topic at a well-child visit — not necessarily a sign that something is wrong, but a starting point for your pediatrician to assess further.

❓ Frequently Asked Questions

Does teething cause fever? +
No. Research consistently shows teething can cause a slight temperature elevation (under 100.4°F) but not a true fever. If your baby has a fever, look for another cause.
Is it normal to have no teeth at 10 months? +
Yes! While most babies get a first tooth by 6-10 months, some perfectly healthy babies don't teethe until 12-14 months. Late teething is usually genetic — ask if you or your partner were late teethers.
When should my baby see a dentist? +
The ADA recommends a first dental visit within 6 months of the first tooth, or by the first birthday — whichever comes first.
What if my baby reaches this milestone earlier or later than the listed range? +
Milestone ranges reflect typical variation across many children, so falling near either end of the range is usually still within normal development. If your baby is notably outside the listed range, it's worth mentioning at your next well-child visit so your pediatrician can assess it in the context of your baby's overall development.
Can a baby skip this milestone entirely? +
Some milestones, like crawling, are commonly skipped by babies who move directly to a later skill (like pulling to stand), and this is generally considered a normal variation. Other milestones are more foundational and less commonly skipped — your pediatrician can help you understand which category a specific milestone falls into.
How is this milestone assessed at a well-child visit? +
Pediatricians typically use a combination of parent-reported observations and brief in-office checks or standardized developmental screening questionnaires, usually administered at specific well-child visits. Bringing specific examples of what you've observed at home helps your pediatrician assess more precisely than general impressions alone.
Does birth order or having older siblings affect when milestones appear? +
It can, informally — later-born children sometimes reach certain physical milestones a bit earlier due to more floor time and modeling from older siblings, though this isn't a formal medical finding and varies significantly between families. It's generally considered a minor influence compared to a child's own individual development pace.
Should I adjust the timeline if my baby was born prematurely? +
Yes — for babies born prematurely, most pediatricians recommend tracking milestones against adjusted age (based on due date rather than birth date) through at least the first two years. This gives a more accurate sense of whether a milestone is on track for your baby's developmental stage.
Do I need to actively "teach" this milestone, or will it happen on its own? +
Most milestones emerge naturally as a baby's nervous system matures, and no amount of drilling or flashcards will make a skill appear before a baby is developmentally ready. That said, providing regular opportunities to practice — safe floor time, varied objects to explore, plenty of talking and reading — genuinely does support development, even if it can't force a milestone to arrive early.
What should I track or write down if I have a concern about this milestone? +
Specific, dated observations are far more useful to a pediatrician than a general sense that something seems off — for example, noting whether a skill has ever been attempted, how consistently it appears, and whether it's improving, staying flat, or going backward over a few weeks. Bringing notes like this to a well-child visit helps your pediatrician assess the pattern rather than relying on memory alone.
