  1. All About Teeth By: Christina Beacham CS 100 BYU Fall 2004

  2. 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 they’re 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.

  4. 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.

  5. 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 tooth’s own personal bodyguard.

  6. 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.”

  7. Pulp Continued • The pulp is where each tooth’s 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 tooth’s blood vessels which help the tooth and keep it alive and healthy.

  8. 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 body’s glue), holds the root of each tooth to your jawbone.

  9. Final Tutorial • Now that you’ve 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.
