Predict when your baby's teeth will emerge — track tooth eruption stages from first tooth to full set of 20 primary teeth
Enter your baby's birth date to see their teething timeline.
Our Teething Age Calculator uses established pediatric dental research to predict which teeth your baby should have at their current age. The calculator compares your child's age in months against standard tooth eruption timelines developed by the American Academy of Pediatric Dentistry.
Baby teeth (also called primary teeth or deciduous teeth) typically emerge in a predictable sequence, though the exact timing varies from child to child. The calculator considers the average age ranges for each tooth type — incisors, canines, and molars — to determine your child's teething stage.
The typical order of tooth emergence is: lower central incisors first, followed by upper central incisors, upper lateral incisors, lower lateral incisors, first molars, canines, and finally second molars. Most children have all 20 primary teeth by age 3.
| Tooth Type | Upper Jaw | Lower Jaw | Typical Age Range |
|---|---|---|---|
| Central Incisor | 8-12 months | 6-10 months | 6-12 months |
| Lateral Incisor | 9-13 months | 10-16 months | 9-16 months |
| First Molar | 13-19 months | 14-18 months | 13-19 months |
| Canine (Cuspid) | 16-22 months | 17-23 months | 16-23 months |
| Second Molar | 25-33 months | 23-31 months | 23-33 months |
Monitoring your baby's tooth eruption timeline is important for their overall health and development. Understanding what to expect helps you prepare for each stage of teething and ensures your child's dental development stays on track.
Identify potential delays in dental development early. If teeth are significantly behind schedule, you can consult your pediatric dentist to address any underlying issues.
Know when to expect teething symptoms and prepare in advance. Understanding the timeline helps you recognize teething-related discomfort versus other causes of fussiness.
Start brushing at the right time for each tooth. Good oral hygiene habits should begin with the very first tooth to prevent early childhood cavities.
Understand normal vs. delayed teething patterns. Every baby develops at their own pace, and knowing the typical ranges helps reduce unnecessary worry.
Most babies get their first tooth (lower central incisor) between 6-10 months of age. However, some babies are born with a tooth, while others don't get their first until 12-14 months. Both extremes are usually normal, but consult your pediatrician if no teeth by 18 months.
The typical order is: lower central incisors (6-10 months), upper central incisors (8-12 months), upper lateral incisors (9-13 months), lower lateral incisors (10-16 months), first molars (13-19 months), canines (16-23 months), and second molars (23-33 months). The lower teeth usually emerge before the upper counterparts.
Common teething symptoms include: increased drooling, chewing on objects, swollen or tender gums, irritability, trouble sleeping, decreased appetite, and mild temperature elevation (under 100.4°F / 38°C). Fever over 101°F is NOT caused by teething and requires medical attention.
Safe remedies include: clean chilled (not frozen) teething rings, gentle gum massage with a clean finger, cold washcloth to chew on, and over-the-child's-age-appropriate pain relievers (consult your pediatrician). Avoid teething gels with benzocaine, amber necklaces (choking hazard), and frozen teethers (can damage gums).
The American Academy of Pediatric Dentistry recommends a first dental visit by age 1 or within 6 months of the first tooth emerging, whichever comes first. Early visits help establish good oral hygiene habits and detect issues early.
