Primary Teeth (Baby Teeth)
The primary teeth begin their development when the
fetus is five weeks old, but do not appear in the
mouth until the lower central incisors erupt at
approximately six months of age. The normal ages of
eruption vary greatly from child to child, although the
sequence in which the teeth erupt does not.

For example, the lower central incisors may appear
as early as two months of age or as late as 12
months. Occasionally a lower incisor may be in place
at birth.

The primary teeth are of major importance to the
child's appearance, chewing ability and eventual
health of their permanent teeth!
The Sequence of Appearance of the Primary Teeth
Every child usually has 20 primary teeth, four each of the five kinds. All 20 of the primary teeth are
usually in place by the time the child is three years old. They generally appear as follows (See the
figure above):

Primary central incisors: (a) 4 to 14 months of age
Primary lateral incisors: .(b) 8 to 18 months of age
Primary canine teeth: ....(c) 14 to 24 months of age
Primary first molars: ......(d) 10 to 24 months of age
Primary second molars: .(e) 20 to 26 months of age
Permanent Teeth
As each of the primary teeth is lost naturally, it is
replaced by a permanent tooth. Heredity plays a
major role in determining the schedule. The figure
above presents the typical case.

The sequence of appearance of the permanent
teeth

Permanent central incisors.....(1): 5 to 9 years
Permanent lateral incisors......(2): 6 to 10 years
Permanent canine teeth.........(3): 8.5 to 14 years
First premolars (bicuspids).....(4): 9 to 14 years
Second premolars (bicuspids)(5): 10 to 15 years
Permanent first molars ..........(6): 5 to 8 years
Permanent second molars......(7): 10 to 15 years
Third Molar..............................(8): 17 to 25 years
Healthy Gums
Healthy gums are essential for healthy growth and development of teeth and continued oral health.
An effective program of preventive dental care is the best assurance that your child will have a lifetime
of excellent oral health!

Gum (periodontal) disease can be prevented by taking the most important step of cleaning your
child's teeth daily. The first stage of gum disease, called gingivitis, occurs in almost all children, so you
should not assume that gum disease cannot occur in your child. Regular visits to our clinic is helpful in
controlling gingivitis.

Dr. Shah can help you learn how to prevent gum disease by teaching both you and your child on how
to brush and floss your child's teeth. Brushing does only half the job, flossing completes it. Your child
should not be expected to master these skills before they are eight years old. They will need your
help to clean their teeth properly.
What is Gum Disease?
Signs of Gum Disease
Cause of Gum Disease
Gum disease starts as a
simple inflammation, and if
neglected, can eventually
destroy the bone that
supports the teeth in the jaws.

Don't be misled. Although
infection is present, there is
seldom any pain.
In the first stage of gum
disease, inflammation and some
bleeding of the gums occur.

An advanced form of gum
disease is periodontitis, which
to the eye resembles gingivitis,
except that some loss of the
bone has occurred. Bone loss in
this stage can be detected only
with the help of an X-ray.
Gum disease is caused by
plaque, a thin, sticky film that
forms daily on the teeth.

If it is not removed by daily
brushing and flossing, food
particles and many kinds of
bacteria mixed with plaque will
cause gum disease.
Common Conditions that can Cause Plaque to Form
Plaque is more easily formed and stubbornly retained in the conditions and circumstances listed below:

  • Emergence (eruption) of the teeth
  • Mouth breathing causes gum tissue to become abnormally dry and easily irritated
  • Crooked teeth (maloccllusion)
  • Oral habits, such as thumb sucking
  • Improper brushing habits
  • Diseases, such as chicken pox, herpes and canker sores. These diseases are, in part,
    associated with gingivitis because they are painful, particularly when the teeth are brushed
  • Some medications. Always inform us of any medications your child may be taking.
The Importance of Proper Diet
Your child's diet is very important in maintaining the healthy condition of their teeth and gums. Teeth
and gums require the same adequate nutrition needed by the rest of the body to stay healthy. Food
that cannot be removed by the saliva and the mouth's normal cleaning actions should be avoided,
unless the teeth are brushed immediately.
