Is your baby suddenly a drool factory, gnawing on everything in sight, or battling a cranky streak? Welcome to teething season—a developmental milestone as unpredictable as it is universal. While some babies flash their first tooth by 3 months, others might keep parents guessing until their first birthday (or beyond).
Teething Timeline: What's Typical?
- First teeth: Most babies sprout their bottom two front teeth between 6–10 months, says family physician Dr. Beth Oller. But timelines vary wildly—some start at 3 months, others after 12.
- Late bloomers: "At 10 months, one of my twins had five teeth; the other just got his first," Oller tells USA TODAY.
- Red flags: No teeth by 12 months? Schedule a dental checkup. Some pros advise waiting until 18 months unless there are other concerns.
Why the Delay? Causes of Late Teething
While genetics often dictate the pace, factors like premature birth, low birth weight, or malnutrition can slow things down. Rarely, developmental conditions (e.g., Down syndrome) or endocrine disorders play a role. But most delays are harmless: "Usually, the answer is simple—their teeth just aren't ready yet," Oller explains.
Complications to watch for:
- Trouble chewing solids
- Speech delays
- Difficulty making certain facial expressions
Soothing Strategies & When to Relax
- Symptoms: Drooling, gum-rubbing, mild fever (<100.4°F), and irritability are normal.
- Comfort tips: Offer chilled (not frozen) teething toys, gentle gum massages, or pediatrician-approved pain relievers.
Bottom line: "Teething isn't a race," says Oller. Celebrate those gummy smiles while they last—those pearly whites will arrive on their own schedule.
