The Scoop on Baby Teeth

Have you wondered whether your child is normal in eruption or losing of baby teeth? The following will give a good guide on what's normal and expected during a child's younger years.

The chart below shows when a child's primary teeth (also called baby teeth or deciduous teeth) should erupt and shed. Eruption times vary from child to child.

TThe first teeth begin to break through the gums at about 6 months of age. Usually, the first two teeth to erupt are the two  two bottom front teeth.

 

Next, the top four front teeth emerge. After that, other teeth slowly begin to fill in, usually in pairs -- one each side of the upper or lower jaw -- until all 20 teeth (10 in the upper jaw and 10 in the lower jaw) have come in by the time the child is 2 ½ to 3 years old.

Primary Teeth Development Chart
Upper Teeth	When tooth emerges	When tooth falls out
Central incisor	8 to 12 months	6 to 7 years
Lateral incisor	9 to 13 months	7 to 8 years
Canine (cuspid)	16 to 22 months	10 to 12 years
First molar	13 to 19 months	9 to 11 years
Second molar	25 to 33 months	10 to 12 years
Lower Teeth
Second molar	23 to 31 months	10 to 12 years
First molar	14 to 18 months	9 to 11 years
Canine (cuspid)	17 to 23 months	9 to 12 years
Lateral incisor	10 to 16 months	7 to 8 years
Central incisor	6 to 10 months	6 to 7 years

Other primary tooth eruption facts:

• A general rule of thumb is that for every 6 months of life, approximately 4 teeth will erupt.
• Girls generally precede boys in tooth eruption.
• Lower teeth usually erupt before upper teeth.
• Teeth in both jaws usually erupt in pairs -- one on the right and one on the left.
• Primary teeth are smaller in size and whiter in color than the permanent teeth that will follow.
• By the time a child is 2 to 3 years of age, all primary teeth should have erupted.

Shortly after age 4, the jaw and facial bones of the child begin to grow, creating spaces between the primary teeth. This is a perfectly natural growth process that provides the necessary space for the larger permanent teeth to emerge. Between the ages of 6 and 12, a mixture of both primary teeth and permanent teeth reside in the mouth.

Why Is it Important to Care for Baby Teeth?

While it's true that baby teeth are only in the mouth a short period of time, they play a vital role. Baby teeth:

• Reserve space for their permanent counterparts
• Give the face its normal appearance.
• Aid in the development of clear speech.
• Help attain good nutrition (missing or decayed teeth make it difficult to chew, causing children to reject foods)
• Help give a healthy start to the permanent teeth (decay and infection in baby teeth can cause damage to the permanent teeth developing beneath them)
