The child who are at the age of 6 and 10 years old have 28 number of mixture of primary teeth and permanent teeth appear in their mouth. And child have 28 number comprise of 8 incisor, 4 canine, 8 premolar and 8 molar teeth.
We know that milk teeth is fall out and new teeth is emerging that is known as permanent teeth. Primary teeth are smaller in size and white in colour than the permanent teeth. By the time of child is 2 to 3 years of age all primary teeth should have erupted.
● incisors: total number of Incisor present in child having 6 and 10 years old is 8. Lower Central Incisor in child, their emerging time is 6 to 10 month and fall out after completion of 6 to 7 year. Lower lateral Incisor their emerging time is 10 to 16 month and fall out after completion of 7 to 8 years.
In upper Central Incisor their emerging time is 8 to 12 months and their fall out time is 6 to 7 years. And upper Lateral Incisor their emerging time is 9 to 13 months and their fall out time is 7 to 8 years.
● canine: total number of canine teeth present in child having 6 and 10 years old 4. Canine teeth is also known as cuspid. First upper canine is erupted and than lower canine. Upper canine their emerging time is 16 to 22 months and their all out time is 10 to 12 years. Emerging time of lower canine is 17 to 23 months of child and their fall out time is 9 to 12 years old.
● premolar :- total number of premolar teeth present in child is 12 who are at the age of 6 and 10 years old child. First upper premolar teeth is emerging out and then lower premolar teeth. Upper first premolar teeth emerging time is 13 to 19 months and their fall out time is 9 to 11 years.
Upper second premolar teeth their emerging time is 25 to 33 months and their fall out time is 10 to 12 years.
Lower first premolar teeth erupted in 14 to 18 months child and they shed about 9 to 11 years of completion of age. And lower second premolar teeth their emerging time is 23 to 31 months and their fall out time is 10 to 12 years.

so the child who are at the age of 6 to 10 years have 28 number of mixture of temporary teeth and permanent teeth in their mouth, comprise of 8 number of Incisor, 4 number of canine, 8 number of premolar and 8 number of molar teeth.
How many teeth does a child have at 13 years ?
