CHEW ON THIS!Test your tooth knowledge with these true or false questions.
Q: George Washington, our first president, had wooden teeth. T or F
A. False. However, Washington did have truly terrible teeth and tried many different kinds of false teeth. Hippopotamus teeth, cow teeth, even teeth mad from ivory. In colonial times, it was not unusual for someone to be missing half his or her teeth.
Q: Paul Revere was a patriot, a silversmith, and also a dentist. T or F
A. Basically true. While he never filled cavities, he did for a brief time advertise that he would make gold false teeth.
Q: Your teeth are the hardest bones in your body. T or F
A. True, except that teeth aren’t bones exactly. And, while they are hard, they are not that hard. It is still a very good idea to wear mouth guards whenever you play sports.
Q: The Egyptians invented toothbrushes. T or F
A. False. Toothbrushes were invented in China about 500 years ago. The first nylon bristle toothbrush appeared in 1938. However, Egyptians did care about their teeth. They chewed on ragged sticks to help keep them clean.
Q: Rats and mice are called rodents because of their teeth? T or F
A. True. The word rodent means to chew or gnaw. Rats and mice have to constantly chew in order to wear down their teeth. The fact is that their teeth never stop growing.
Q: Shark have many teeth. T or F
A. Boy is that true! In fact, they have rows and rows of teeth. They also replace any teeth they lose. A shark can have upwards of 50,000 teeth in as lifetime.
Q: All mammals have especially sharp teeth called canines for tearing food apart.T or F
A. False. Humans do. But mammals like horses and cows are plant eaters. They don’t have canines. And some whales don’t have teeth at all.
Q: . Teeth can’t possibly be a living part of the human body. T or F
A. False. Teeth are kept alive by the blood and nerves at their center.
Q: All around the world, people believe that the tooth fairy visits the children who put a tooth underneath their pillow. T or F
A. False. In many countries, it is thought that a mouse visits and exchanges the tooth for a candy or coin.

The sweet life of taking care of your child’s teethTooth Be Told Names of Individual teeth: The mouth is divided into four parts called quadrants – the upper left quadrant, the upper right quadrant, the lower left quadrant, and the lower right quadrant. Then, each individual tooth in the quadrant is given a name. For example the two upper and two lower teeth at the center of your mouth are called centrals, and the central on the upper right side of your mouth is called an upper right central.Tooth or Consequences The remaining permanent teeth are designated as follows: Central: The two upper and two lower teeth in the very center of your mouth. Lateral: The teeth just adjacent to the centrals. Cuspid: The pointy teeth just behind the laterals. These teeth have one cuspal (or point). Cuspids are also called canines. First Bicuspid: The teeth just behind the cuspids. These teeth have two cuspals (or points) Second Bicuspid: The teeth just behind the first bicuspids. These teeth have two cuspals. First Molar: The teeth just behind the second bicuspids and have a level surface with four cuspals. Second Molar: The teeth just behind the first. These teeth also have a level surface with four cuspals. Third Molar: The teeth just behind the second molars. These teeth also have a level surface with four cuspals. Apex: The very bottom of the root of your tooth Cementum: A bony substance covering the root of a tooth. Crown: The part of your tooth above your gum. Dentin: The calcium part of a tooth below the enamel. Enamel: A hard ceramic which covers the exposed part of your teeth.
Tooth Be ToldYour mother might have told you to “chew your food,” however most people do not do this well. When the idea of sitting down for a relaxing meal takes second � ddle to the pressures and stress of our modern-day, on-the-go lifestyles, it is no surprise that many people do not take the time to chew their food.
Tooth or ConsequencesMost people think that digestion begins in the stomach. Yet, this process actually begins in the mouth.
• The action of chewing breaks down food into smaller particles. This results in the food having increased surface area, an important factor in good digestion.
• Chewing food well allows it to be exposed to saliva for a longer period of time. Saliva lubricates the food, making it easier to pass through the digestive system.
• When food is not well chewed, the food particles are too big to break down properly. Incomplete digestion occurs. Nutrients do not get extracted from the food.
• The process of chewing also signals the stomach that the entire digestive process has begun.
An Extra Bite for Mom and DadA good rule of thumb for chewing food is: If you can tell what kind of food you are eating from the texture of the food in your mouth (not the taste), then you haven’t chewed it enough. For example, if you are chewing broccoli and you run your tongue over the stalk and can tell that it is still a stalk, don’t swallow, keep chewing. You need to keep on chewing until you can’t tell it’s the stalk.
Can you label the parts of your digestive system?
stomach
mouth
anus
large intestine
rectum
small intestines
esophagus
Your MouthIt all starts with that � rst bite. Your teeth rip o� a piece of apple. Boy does that taste good! Now the glands in your mouth get busy spraying saliva. That makes the apple mush wetter. Chemicals in the saliva start to break it apart. Just a few more chews. Now your tongue pushes the wet mess to the back of your mouth. A trap door opens! Down it goes.
Your EsophagusThe mush is pushed down a long tube called the esophagus. Muscles squeeze the tube as if it’s a tube of toothpaste. The mush reaches the bottom. Another trap door opens! Plop!
Your StomachThe apple mush lands in your stomach. Think of this place as the inside of a pink hot water bottle. Muscles on the outside contract. The contents inside slosh back and forth, back and forth. It feels like waves in the ocean. Meanwhile, stomach acid sprays out from the stomach walls. The chemicals and the movement break the slop apart even more.
Your Small IntestinesNow another trap door opens. The mush is pushed down into your small intestines. More chemicals from places like your kidneys break the mush apart even more. Small � nger-like sponges soak up the nutrients. Like a sponge, they absorb what your body can use. Those nutrients � ow to your blood stream. They get delivered to places all over your body.
Your Large IntestineMeanwhile the leftovers keep on traveling. In the large intestine the leftovers start to dry up. Liquids are removed to become pee.
Your RectumThe rest continues to move down the digestive system. In the rectum, things dry out. What’s left gets smaller and harder. It has been a long journey. Everything you eat has been put to good use. The stu� that your body can use has been recycled. The rest leaves as pee or poop.
Chewing is the � rst step in digestion. And without digestion, your body wouldn’t get what it needs to live and grow.

The digestion process begins with your teeth. Here’s how it works…
