Primary Teeth- (Baby)

• Primary teeth are your first set of teeth.
• You usually have all of these by the time you are
  3 years old.
• There are 20 Primary teeth in all.
• When you get to be at the age of 5 or 6 these
  teeth begin to fall out.

3
Permanent Teeth (Teen)

• Primary teeth fall out because theyre being
  pushed out by the permanent teeth coming in.
• Most people have all of their permanent teeth by
  the age of 14.
• There are a total of 28
• permanent teeth.

Wisdom Teeth (Wise)

• Around about age 20, four more teeth called
  wisdom teeth grow in at the back of the mouth.
• They complete the adult set of 32 teeth.

Tooth Tour The Crown Enamel

• The part of the tooth you can see above the gum
  is the crown of your tooth.
• The crown of each tooth is covered with enamel.
• The enamel works as
• the tooths own personal
• bodyguard.

Dentin Pulp

• Dentin makes up the largest part of the tooth and
  is similar
• to bone. It is also very
• hard.
• Dentin protects the
• innermost part of the
• tooth called the Pulp.

Pulp Continued

• The pulp is where each tooths nerve endings are
  found.
• The nerve endings
• inside the pulp send
• messages to your brain
• like, that soup is too
• hot!
• The pulp also contains
• the tooths blood vessels which
• help the tooth and keep it alive and
• healthy.

Cementum

• Both the dentin and pulp go all the way down into
  the root of the tooth, which is under the gum.
• Cementum (which is like your bodys glue), holds
  the root of each tooth to your jawbone.

Final Tutorial

• Now that youve learned some basics about your
  teeth, its important to know how to keep those
  teeth in tip top shape.
• Brushing your teeth with fluoride toothpaste is
  your best bet when it comes to keeping your teeth
  in tip-top shape. Try to brush after eating or at
  least twice a day. It's especially important to
  brush before bedtime. Brush up and down, rather
  than side to side. You'll also want to floss your
  teeth - at least once a day. That removes food
  and plaque that gets stuck in between your teeth.
