Tooth Eruption
Alternate Names : Teeth Eruption, Eruption of Teeth, Teething
When a tooth or teeth come through the gum line, that is known as tooth eruption. This is a normal process of the body. The first set of teeth a child has is called the primary or deciduous teeth. As a child loses the primary teeth, the second set of teeth, known as the permanent or secondary teeth, comes through the gum line. Teeth are named for their location in the mouth and the function they serve. Incisors cut the food, and canines tear the food. Premolars crush the food, and permanent molars grind the food.

The typical age for tooth eruption can vary widely from child to child. Usually, the first teeth erupt at about 6 to 8 months of age. The baby, or primary, teeth generally erupt in the following pattern:
Upper teeth:
Central incisors, or the front teeth, appear between 8 and 13 months old.
Lateral incisors, the ones on each side of the front teeth, appear between 8 and 13 months old.
Canines, also known as cuspids, appear between 16 and 23 months old.
First molars appear between 13 and 19 months old.
Second molars appear between 25 and 33 months old.
Lower teeth:
Central incisors appear between 6 and 10 months old.
Lateral incisors appear between 10 and 16 months old.
Canines, or cuspids, appear between 16 and 23 months old.
First molars appear between 13 and 19 months old.
Second molars appear between 23 and 31 months old.
All 20 primary teeth have usually erupted by the age of 30 months or 2 1/2 years old.
Even while the primary teeth are erupting, the permanent teeth develop beneath the primary teeth. When a child is around the age of 6 years old, the primary teeth begin to fall out, and the permanent teeth appear through the gum line. The permanent teeth usually appear in the following pattern:
Upper teeth:
Lateral incisors appear between 8 and 9 years old.
Canine teeth appear between 11 and 12 years old.
First premolar appears between 10 and 11 years old.
Second premolar appears between 10 and 12 years old.
First permanent molar appears between 6 and 7 years old.
Second permanent molar appears between 12 and 13 years old.
Third permanent molar, also known as a wisdom tooth, appears between 17 and 21 years old.
Lower teeth:
Central incisors appear between the ages of 6 and 7 years old.
Lateral incisors appear between 7 and 8 years old.
Canine teeth appear between 9 and 10 years old.
First premolar appears between 10 and 12 years old.
Second premolar appears between 11 and 12 years old.
First permanent molar appears between ages of 6 and 7 years old.
Second permanent molar appears between 11 and 13 years old.
Third permanent molar, or wisdom tooth, appears between 17 and 21 years old.
Usually when the second permanent molar appears, most of the 32 permanent teeth are present.
