The teeth for each child differ from shape, size as well as their location. Normally, there are 20 primary teeth at birth as per the American Dental Association (ADA). These baby teeth begin to erupt during the first 6 months since birth. The shedding of these primary teeth (which is also known as deciduous teeth) varies at different times during childhood. Permanent teeth, on the other hand, usually begin to erupt starting at the age of 6. This article will help you learn and explain to you thoroughly when the primary teeth erupt and fall out as well as what age the permanent teeth start to erupt.

The chart below displays the time period when baby teeth generally come in and shed. Take note that this timetable is just a generic guide and that the tooth eruption time period for each child can be different.
Upper Teeth | Erupt | Shed |
Central incisor | 8-12 mos. | 6-7 yrs. |
Lateral incisor | 9-13 mos. | 7-8 yrs. |
Canine (cuspid) | 16-22 mos. | 10-12 yrs. |
First molar | 13-19 mos. | 9-11 yrs. |
Second molar | 25-33 mos. | 10-12 yrs. |
Lower Teeth | Erupt | Shed |
Second molar | 23-31 mos. | 10-12 yrs. |
First molar | 14-18 mos. | 9-11 yrs. |
Canine (cuspid) | 17-23 mos. | 9-12 yrs. |
Lateral incisor | 10-16 mos. | 7-8 yrs. |
Central incisor | 6-10 mos. | 6-7 yrs. |

As seen on the time table above, the first primary teeth start to come in during the first 6 months of the baby’s age. Generally, the first 2 teeth to come in are the 2 lower central incisors. The next teeth to erupt are the upper 4 incisors then the following teeth to erupt slowly come in pairs – about 10 on each side of both the upper and lower jaws. These baby teeth erupt until all 20 deciduous teeth are complete by the time the kid reaches 2-3 years of age to 6-7 years old.
The following timetable demonstrates when the permanent teeth (adult teeth) normally start to erupt. Similar to the chart for the teeth eruption of children above, this timetable is a common guide. The time period for the teething for each person may vary.
Upper Teeth | Erupt |
Central incisor | 7-8 yrs. |
Lateral incisor | 8-9 yrs. |
Canine (cuspid) | 11-12 yrs. |
First premolar (first bicuspid) | 10-11 yrs. |
Second premolar (second bicuspid) | 10-12 yrs. |
First Molar | 6-7 yrs. |
Second Molar | 12-13 yrs. |
Third molar (wisdom tooth) | 17-21 yrs. |
Lower Teeth | Erupt |
Third molar (wisdom tooth) | 17-21 yrs. |
Second Molar | 11-13 yrs. |
First Molar | 6-7 yrs. |
Second premolar (second bicuspid) | 11-12 yrs. |
First premolar (first bicuspid) | 10-12 yrs. |
Canine (cuspid) | 9-10 yrs. |
Lateral incisor | 7-8 yrs. |
Central incisor | 6-7 yrs. |

The first permanent teeth to erupt vary for each kid. The first adult teeth to emerge in some young ones are the molars while the first permanent incisors are the first to erupt in some others. Normally, almost all of the 28 adult teeth will emerge when the child reaches 13 years old. When a kid reaches the age of 17 to 21, about 1 to 4 wisdom teeth (also called as third molars) will come in, making a total of 32 permanent teeth.
