Baby teeth grow first in the lower center of the baby's mouth, which are the bottom central incisors.
These bottom central incisors are then followed shortly by the top 2 front teeth or the upper central incisors.
The bottom front teeth in a baby erupt or grow between the ages of 6 months to 10 months of age.
Then the top front teeth erupt or grow between the ages of 8 to 12 months old and then finally the top and bottom side teeth or lateral incisor teeth grow or erupt by 9 to 16 months of age.
Although every baby is different and some baby begin cutting teeth or growing teeth as early as 4 months of age or even as late as 12 months of age.
The age at which the 32 human teeth grow is between ages 17 to 25.
Your full set of 32 permanent human teeth often grow in between your late teens and early twenties or between age 17 to 25.
The 32 human teeth is the final set of teeth, which is also achieved when your 4 third molars, which are often called "wisdom teeth," fully erupt in the back of your mouth.
Between the ages of 6 to 13, most of your baby teeth fall out and are then replaced by 28 permanent teeth.
Then between the ages of 17 to 25, the last 4 of your teeth also known as your "wisdom teeth" often emerge to complete the 32 tooth set.
And because your wisdom teeth can also cause crowding sometimes or become impacted, many adults usually have the wisdom teeth removed, which leaves them with only 28 permanent teeth.
While 32 teeth is the anatomical standard for human adults (including four wisdom teeth), having all 32 naturally is actually somewhat rare in adulthood.
Many adults instead actually end up with 28 teeth because wisdom teeth are frequently extracted due to crowding or impaction.
Here is why having a complete set of 32 is uncommon:
Wisdom Tooth Agenesis: A significant portion of the population is congenitally missing one or more wisdom teeth.
Orthodontic Extractions: Dentists frequently remove premolars or wisdom teeth to correct alignment issues.
Hyperdontia: Having more than 32 teeth is also a recognized dental anomaly (affecting up to 3.8% of the population), while naturally keeping all 32 teeth into late adulthood is incredibly uncommon.
Most adults have 32, children have 20 — but your exact number matters less than the condition of those teeth.
Healthy teeth support your nutrition, confidence, and overall health.
