Tracking Your Baby's First Teeth
Recording when each of your baby's 20 primary teeth erupts gives you a personal milestone record and helps identify any teething concerns to discuss with your dentist. Most babies follow a broadly predictable eruption sequence, though individual timing varies significantly - up to 6 months either side of average is normal.
Once your baby's first tooth appears, the ADA and AAPD recommend scheduling their first dental visit immediately - within 6 months of that first tooth, or by age 1. This early visit is about establishing habits, not finding problems. See our Baby Teeth Eruption Chart for a full visual timeline of all 20 primary teeth, and our Pediatric Fluoride Dosage Calculator to confirm the right toothpaste amount once brushing begins.
Primary Tooth Eruption Order
Baby teeth typically erupt in a predictable sequence, though the timing varies considerably between children:
- Lower central incisors - first teeth to appear, usually 6–10 months
- Upper central incisors - 8–12 months
- Upper lateral incisors - 9–13 months
- Lower lateral incisors - 10–16 months
- First primary molars - 13–19 months (upper), 14–18 months (lower)
- Primary canines - 16–22 months (upper), 17–23 months (lower)
- Second primary molars - 25–33 months (upper), 23–31 months (lower)
A full set of 20 primary teeth is usually complete by age 2.5–3. To track which permanent teeth replace each primary tooth and when, use our Child's Dental Age Calculator.
