Babies usually start getting teeth around 4–7 months old, but there’s a wide normal range from about 3–12 months.

Typical teething timeline

Here’s a commonly used rough timetable for when do babies teeth come in (baby teeth/primary teeth):

[3] [3] [3] [3] [9][3] [9][3] [3] [3] [9][3] [9][3]
Tooth Upper jaw Lower jaw
Central incisors (front middle teeth) 8–12 months6–10 months
Lateral incisors (next to middle) 9–13 months10–16 months
First molars 13–19 months14–18 months
Canines (cuspids) 16–22 months17–23 months
Second molars 25–33 months23–31 months
Most kids have a full set of 20 baby teeth by around age 3.

What parents usually notice

Common signs that teeth are coming:

  • Extra drooling and chewing on hands or toys.
  • Swollen or bumpy gums where the tooth will appear.
  • Fussiness, especially at night, and disrupted sleep.
  • Slightly decreased appetite or more interest in cold foods.

Mild temperature elevation can occur, but a real fever, bad cough, vomiting, or diarrhea is not considered “just teething” and should be checked by a doctor.

When timing is “late”

There’s a big normal range, and some babies get their first tooth after their first birthday and are still healthy. As a general rule of thumb, it’s reasonable to ask a pediatrician or pediatric dentist to take a look if:

  • No teeth by about 12–15 months.
  • Teeth seem very crooked or asymmetrical as they erupt.
  • Your child has other growth/development concerns at the same time.

Quick care tips once teeth show

  • Gently wipe or brush the new teeth twice a day with a soft baby toothbrush and water.
  • Avoid letting baby fall asleep with a bottle of milk or juice, which can increase cavity risk.
  • For discomfort, many pediatric sources recommend chilled (not frozen) teething rings or a clean cold washcloth to chew on; ask your pediatrician before using any medicines.
