Baby Teeth Eruption: A Complete Guide for Parents
Understanding when your child's teeth should appear - and when to be concerned - is one of the most common parenting questions. This chart uses AAPD 2026 eruption data for all 20 primary (baby) teeth and 32 permanent teeth to give you an age-specific assessment.
Once you know your child's current dental stage, our First Tooth Tracker lets you log exact dates for each tooth, while the Dental Age Calculator provides a broader developmental overview including shedding timelines.
Primary Teeth Eruption Order and Timeline
All 20 primary teeth erupt in a broadly predictable sequence, though individual timing can vary by 4–6 months either side:
- 6–10 months: Lower central incisors (first teeth in most babies)
- 8–12 months: Upper central incisors
- 9–16 months: Lateral incisors (upper then lower)
- 13–19 months: First primary molars
- 16–23 months: Primary canines
- 23–33 months: Second primary molars (last baby teeth)
Use our Pediatric Fluoride Calculator to confirm the right toothpaste amount for each eruption stage, and pair brushing with our 2-minute Brushing Timer in Kid Mode.
Permanent Teeth: When Baby Teeth Are Replaced
Permanent teeth begin erupting around age 6, initially alongside remaining baby teeth - creating the mixed dentition phase. The sequence broadly mirrors the primary eruption order:
- Age 6–7: First permanent molars and lower central incisors
- Age 7–8: Upper central incisors, lower lateral incisors
- Age 8–9: Upper lateral incisors
- Age 9–12: Canines and premolars
- Age 11–13: Second permanent molars
- Age 17–21: Third molars (wisdom teeth) - often impacted, frequently extracted
During the mixed dentition phase (ages 6–12), orthodontic assessment is valuable. Use our Orthodontic Readiness Checker to assess whether your child is ready for an ortho evaluation, and our Braces Cost Estimator to plan financially.
