At Firestone Pediatric Dentistry & Orthodontics, we believe that knowledge empowers parents to better support their child’s oral health. That’s why we’ve created this easy-to-follow tooth eruption guide, so you know what to expect as your child’s smile develops—starting with baby teeth and continuing through the eruption of permanent teeth.

Baby Teeth (Primary Teeth) Eruption Timeline

Most children begin to get their baby teeth around 6 months of age, and the full set of 20 primary teeth is usually in place by age 3. Here’s a general guide:

• 6–10 months – Lower central incisors
• 8–12 months – Upper central incisors
• 9–13 months – Upper lateral incisors
• 10–16 months – Lower lateral incisors
• 13–19 months – First molars
• 16–22 months – Canines (cuspids)
• 23–33 months – Second molars

These primary teeth play a critical role in speech, chewing, and guiding permanent teeth into the proper position later on.

Permanent Teeth Eruption Timeline

Most children begin losing baby teeth around age 6. The full set of 28 adult teeth (not including wisdom teeth) typically finish coming in by age 12–13. Here's the usual pattern:

• 6–7 years – Lower and upper central incisors
• 7–8 years – Lateral incisors
• 9–12 years – Canines
• 10–12 years – Premolars (first and second)
• 6–7 years – First molars
• 11–13 years – Second molars
• 17–21 years – Third molars (wisdom teeth, if present)

Tooth eruption can vary slightly from child to child. Our team monitors this process closely during your child’s routine visits to ensure proper development.

Why Monitoring Tooth Eruption Matters

Tracking the eruption of baby and permanent teeth is an important part of preventive pediatric dental care. Early or delayed eruption, extra teeth, or crowding can signal the need for orthodontic intervention. We use digital X-rays and growth assessments to monitor these milestones and identify issues early—ensuring your child’s oral development stays on track.
