What is Tooth Eruption?

Tooth eruption is the natural process in which teeth emerge through the gums and become visible in the mouth. This occurs in a specific sequence, beginning with the eruption of primary (baby) teeth in infancy, typically around six months of age, and continuing with the emergence of permanent teeth during childhood and adolescence. 

The process is influenced by genetics, overall health, and jaw development. While most teeth erupt without complications, some may be delayed, impacted, or cause discomfort. Proper oral hygiene and regular dental check-ups help ensure a smooth eruption process and prevent potential issues.

Tooth Eruption Timeline Chart By Age

Tooth eruption is a natural process where teeth emerge through the gums at different stages of life. It occurs in two phases: primary (baby) teeth and permanent (adult) teeth.

Primary (Baby) Teeth Eruption:

1. Central Incisors:
• Lower: 6–10 months
• Upper: 8–12 months
2. Lateral Incisors:
• Lower: 10–16 months
• Upper: 9–13 months
3. First Molars:
• Lower: 14–18 months
• Upper: 13–19 months
4. Canines (Cuspids):
• Lower: 17–23 months
• Upper: 16–22 months
5. Second Molars:
• Lower: 23–31 months
• Upper: 25–33 months

Baby teeth begin to fall out around age 6, making way for permanent teeth.

Permanent (Adult) Teeth Eruption:

1. First Molars: 6–7 years
2. Central Incisors: 6–8 years
3. Lateral Incisors: 7–9 years
4. First Premolars: 10–12 years
5. Second Premolars: 10–12 years
6. Canines (Cuspids): 9–12 years
7. Second Molars: 11–13 years
8. Third Molars (Wisdom Teeth): 17–25 years (if they erupt)

Most children have all their baby teeth by age 3 and start losing them around age 6. Permanent teeth usually replace baby teeth by age 12-13. Wisdom teeth may not erupt in everyone, and some may require removal.

Regular dental check-ups help ensure healthy eruption and detect any issues early.

This timeline may vary slightly for each individual, but it provides a general guideline for parents and caregivers to monitor their child’s dental development.

Tooth Eruption Timeline Kids

Tooth eruption in kids occurs in two stages: the eruption of primary (baby) teeth and the replacement by permanent (adult) teeth. Baby teeth begin emerging around six months of age, starting with the lower central incisors, followed by the upper central incisors at about eight to twelve months. By the time a child turns one, lateral incisors start appearing, and the first molars typically erupt between 13 to 19 months. Canines emerge between 16 to 23 months, and the second molars, the last of the baby teeth, usually appear between 25 to 33 months. Most children have all 20 baby teeth by age three.

Tooth Eruption Timeline Adults

In adults, tooth eruption refers to the emergence of permanent teeth, which typically begins in childhood and continues into early adulthood. Most permanent teeth erupt between the ages of 6 and 13, starting with the first molars and central incisors around age six, followed by lateral incisors, premolars, canines, and second molars by the early teenage years. 

By the age of 13, most adults have 28 permanent teeth in place. The final set of teeth, the third molars or wisdom teeth, usually emerge between the ages of 17 and 25, though not everyone develops them. In some cases, wisdom teeth may remain impacted or cause complications, requiring extraction. While the timeline for tooth eruption varies slightly from person to person, regular dental check-ups help monitor oral health and ensure proper tooth development.
