You've been watching for that first tiny white ridge for what feels like forever, comparing notes with friends whose babies sprouted teeth months ago, and quietly wondering: is something wrong that mine has none yet? Almost certainly not. Teeth run on their own schedule, and that schedule is genuinely wide.
The reassuring headline: most babies get their first tooth around 6 months, but anywhere from about 4 to 12 months is normal — and a late first tooth is almost never a problem.
What the science says
According to the American Academy of Pediatrics, the first tooth usually appears around 6 months, with 4 to 7 months being typical — and plenty of perfectly healthy babies don't pop a tooth until closer to their first birthday. The AAP also notes that a rare few babies are even born with a tooth. So the full normal window stretches from birth all the way to around the first birthday.
The usual order: the two bottom front teeth (lower central incisors) tend to come first, followed by the two top front teeth, then the ones on either side, working back toward the molars. By the time your child is about 3 years old, they'll typically have the full set of 20 baby teeth.
The headline to tape to the fridge: variation is normal, and a late first tooth tells you nothing worrying. Teeth don't arrive on a leaderboard, and an early or late mouthful says nothing about how clever or coordinated your baby is. This is the same idea behind why milestones beat ages — the range is the point.
Why late teeth are usually fine
It's easy to read a late first tooth as a sign something's behind. It almost never is. Tooth timing is largely set by genetics — if you or your partner teethed late, your baby may too. A baby happily babbling, rolling, and gumming purées at 10 months with zero teeth is doing exactly what their body planned.
Late teeth also don't hold up feeding. Babies do a remarkable amount of "chewing" with their gums, which is why starting solids doesn't wait for teeth. Gums are tougher than they look.
The one age worth flagging: if no teeth have appeared by around 18 months, mention it at a well-visit so your pediatrician or dentist can take a look. The American Academy of Pediatric Dentistry is the right resource here. Until that point, though, there's simply no race to win.
What to do while you wait (and once it arrives)
While you're waiting, nothing is required of the teeth themselves — but good mouth care starts before any tooth. The AAPD recommends wiping your baby's gums with a clean, damp cloth or soft infant toothbrush from around birth, which clears milk residue and builds the habit.
The moment that first tooth breaks through, the rules change: start brushing twice a day with a rice-grain-sized smear of fluoride toothpaste, and plan the first dental visit by the first birthday — or within six months of the first tooth, whichever comes first. Our full guide on going from first tooth to first dental visit walks through the whole routine, and the teething timeline and relief guide covers soothing sore gums when a tooth is actually on its way.
When to call your pediatrician or dentist
Late teeth rarely need a call, but reach out if:
- No teeth have appeared by about 18 months — worth mentioning at a checkup so your pediatrician or dentist can have a look.
- You notice anything unusual about how the gums or emerging teeth look — discoloration, swelling that isn't a tooth coming, or teeth that seem to be coming in oddly.
- Your baby has a fever of 100.4°F (38°C) or higher, which is never caused by teething. In a baby under 3 months, that's a medical emergency — see newborn fever: when to worry.
If you like tracking which teeth arrive and when, you can log each new tooth in the TinyWins app so you've got a clear record to mention at the next dental or well-child visit.
The bottom line
Most first teeth show up around 6 months, with anywhere from 4 to 12 months entirely normal — and a late first tooth is almost never something to fix. Teeth come on their own schedule, in roughly the bottom-front-first order, building to a full set of 20 by about age 3. Keep cleaning those gums, watch for the first tooth without counting the days, and only raise a flag if there are still none by around 18 months.
