How Long Does It Take for Permanent Teeth to Grow?

Permament TeethWhile there are only 20 primary teeth, most people have 32 permanent teeth in their mouth by the time they reach adulthood. While these teeth are referred to as permanent, they must be taken care of properly if they are to last. The timeline for permanent teeth emergence usually occurs during the years between the age of six and the early twenties.

Permanent Teeth Timeline

Ages 6 to 9

When looking at the timeline for permanent teeth, it’s important to note that the earliest ones replace primary teeth that fall out to make room for them. The first molars emerge between the ages of 6 and 7 on both the upper and lower jaws. Next in the timeline for permanent teeth are the lower central incisors that come in between ages 6 and 7, while the upper ones emerge between ages 7 and 8. The lateral incisors appear next (lower ones between the ages of 7 and 8 and upper ones between the ages of 8 and 9).

Ages 10 to 13

According to the timeline for permanent teeth emergence, the years between 10 and 12 will see the eruption of a number of teeth. Between the ages of 10 and 11, the first premolars (first bicuspids) of the upper jaw emerge. Between the ages of 10 and 12, the first premolars (first bicuspids) on the lower jaw emerge, and the second premolars (second bicuspids) break through the gums. Between the ages of 11 and 12, the upper canine teeth (cuspids) erupt along with the second premolars (second bicuspids) on the lower jaw. Between the ages of 11 and 13, the second molars on the lower jaw erupt through the gums. Between the ages of 12 and 13, the second molars on the upper jaw emerge. However, this isn’t the end of the timeline for permanent teeth.

The Third Molars

Also known as the wisdom teeth, the third molars are the last teeth to erupt. When they appear during the normal timeline for permanent teeth, the wisdom teeth emerge between the ages of 17 and 21.
