History of Teeth

Mummy tooth decay

How did the mummy die?

This is what researchers wanted to know. They were studying a mummy they called Djed [jed]. The researchers knew she was a woman. They knew she had lived more than 3,000 years ago in Egypt. Based on the paintings on her coffin, they also knew Djed loved music and was married. And somehow, when she was about 30, Djed died.

Had she been bitten by a cobra? Attacked by a crocodile?

After using modern tools to study Djed, they discovered the surprising answer: She died because of a bad tooth.

The experts took X-rays of Djed’s 3,000-year-old jaw. They saw that one of her teeth had never grown in. Over time, the hole in her gum got infected. Today, this infection could easily be cured with medicines called antibiotics. But those did not exist in Djed’s time. Scientists believe Djed’s infection spread into her blood and killed her.

Terrible Fact of Life

Today, we know that proper brushing and flossing can prevent most serious tooth problems. When we have trouble with our teeth, there are trained dentists who can help.

But look back into history, and you’ll find millions of people suffering from horrible tooth pain. Knights would charge into battle with oozy sores on their gums. Princesses would cover their rotting teeth with hankies when they smiled. Many people lost most or all of their teeth by the time they were middle-aged. George Washington had only one natural tooth left by the time he became president!

This is why people were always looking for ways to feel less pain and have better smiles.

We now know that proper brushing and flossing is important. It can prevent most serious tooth problems. Trained dentists can help us when we have trouble with our teeth.

But look back into history. Millions of people suffered from very bad tooth pain. Knights went into battle with oozy sores on their gums. Princesses covered their rotting teeth with hankies when they smiled. Many people lost most or all of their teeth by the time they were middle-aged. George Washington had only one natural tooth left by the time he became president!

This is why people were always looking for ways to feel less pain and have better smiles.

Barbers as Dentists?

Some long-ago tooth treatments were not so different from what we do today. The Romans, for instance, understood that teeth needed to be replaced when they fell out. So they used bone, wood, or ivory to create fake teeth. Those teeth were similar to the false teeth people wear now. In Egypt, people made braces out of cat intestines.

By the 1700s, some people were using science to tackle tooth problems. Dentists were better trained. They used proper tools to fix and remove teeth.

But only the rich went to dentists. Most people relied on barbers to care for their teeth. That’s right: The same person who cut your hair also yanked your teeth—with pliers.

The worst part?

There weren’t many ways to help the pain caused by tooth problems.

Obsessed With Teeth

In the 1800s, people understood more about taking care of teeth. Dental schools opened across Europe and the U.S. New laws stated that dentists had to have a license. So barbers could no longer pull teeth. And in the years to come, Americans became obsessed with their teeth.

Today, around 300,000 dentists, hygienists, and orthodontists work in the U.S. The most common tooth problem? Cavities. These form when bacteria make acids that eat away at our teeth and create holes. Dental experts have powerful X-ray machines to spot cavities and other problems. Their tools clean teeth and gums. They give special medicine to stop pain. And they use braces to straighten teeth.

Many dentists volunteer to help people who have trouble paying for dental care. Sadly, none of this was around to help Djed. But if scientists ever study our bodies in the future, they probably won’t find that any
of us died because of a bad tooth.

SUGAR TROUBLES

Humans first started to have tooth problems about 10,000 years ago. That’s when people began farming wheat, corn, and other grains. After we eat these grains, our bodies turn them into sugar, which causes cavities.

TOOTH ROBBERS

In the 1800s, when a soldier died during a battle, criminals would steal his teeth. They would sell these teeth to dentists, who used them to fix the smiles of rich people.

MAGICAL WATER?

A mineral called fluoride is added to tap water in parts of the U.S. Why? Because fluoride, also found in many toothpastes, protects teeth from cavities. People whose homes have water with fluoride tend to have healthier teeth.

Step-by-Step Lesson Plan

1. PREPARING TO READ

Preview Text Features/ Set a Purpose for Reading (10 minutes)

  • Direct students to the labels on page 10 that say “Paired Texts” and “One Topic, two stories.” Ask them to read aloud the titles and subtitle on pages 10 and 13. Then ask students to identify the topic of both stories. (how people have taken care of their teeth over time)
  • Point out the word gruesome on page 10 and explain that it refers to something that is disgusting or frightful. Then direct students to the photos and captions on page 10. Read aloud the captions with the class. Which photos do students think are gruesome? Fascinating? Why do they feel this way?
  • Point to the subheads on pages 11 and 12. Explain that the word obsessed means thinking about something constantly.
  • Direct students to the timeline on page 13. Read aloud the first and last entries with the class. Remind students to read each entry in the top row of the timeline before reading the bottom row.
  • Call on volunteers to read aloud the Think and Read box on page 11 and the Think and Write box on page 13. As students read both texts, ask them to look for details that describe tooth problems and care long ago and today.

Preview Vocabulary (15 minutes)

  • We have highlighted in bold six words that may be challenging and defined them on the page. Preview these words by projecting or distributing our Vocabulary Skill Builder and completing it as a class. You may also play our Vocabulary Slideshow, where images and audio help students with comprehension and fluency.
  • Highlighted words: infected, intestines, pliers, hygienists, orthodontists, bacteria

2. CLOSE READING

Reading and Unpacking the Text

  • First read: Students should read the article and the timeline one time for general comprehension.
  • Second read: Distribute the Close-Reading and Critical-Thinking Questions to the class. Preview them together. Ask students to read the articles again and answer the questions as a class or in small groups. (These questions are now available in Google Forms on our site, so students can type in their answers and send them to you.)

Close-Reading Questions (30 minutes)

  • Read the first section of “History of Teeth.” What caused Djed’s death in ancient Egypt? (cause and effect) Her gums became infected. That infection spread into her blood and killed her.
  • Read “Terrible Fact of Life.” Explain in your own words why people were always searching for ways to “feel less pain and have better smiles”? (summarizing) People suffered from horrible tooth pain, gum sores, and rotting teeth. By the time they were middle-aged, many people lost their teeth from tooth decay.
  • Why don’t people suffer from these serious tooth problems today? (compare and contrast) Today, people care for their teeth by brushing, flossing, and visiting their dentists.
  • Read “Barbers as Dentists?” What treatments used by ancient Romans and Egyptians are similar to modern-day tooth care? (key details) Romans made fake teeth from bone, wood, or ivory. Egyptians used cat intestines to make braces.
  • How did tooth care change in the 1700s? (main idea) Trained dentists used tools to fix and remove teeth.
  • Read “Obsessed With Teeth.” How do dental experts today use modern tools to care for our teeth? (key details) X-ray machines identify problems. Other tools clean teeth and gums. Special medicine stops pain and braces straighten teeth.
  • Read “Teeth Through Time.” What tooth problem did people have 10,000 years ago? How did people in ancient times treat this problem? (putting ideas together) They developed cavities after eating grains that turned into sugar. They filled cavities with silver, earwax, and mashed-bird brains.
  • Why is tap water with fluoride called “Magical Water”? (drawing conclusions) When fluoride is added to drinking water, people have healthier teeth.

Critical-Thinking Question (10 minutes)

  • Think about the article and the timeline. What are three common tooth problems that people suffered from for thousands of years? How did they solve these problems long ago and today? (putting ideas together) People suffered from tooth pain, infections, and crooked teeth. Hebrews used salt to treat the pain, and in the 1700s people used crushed ladybugs. Today, dentists stop tooth pain with special medicine. In ancient times, there was no cure for a tooth infection. Today, dentists use antibiotics. To straighten teeth, ancient Egyptians made braces out of cat intestines. Today, many Americans wear braces.

3. SKILL BUILDING

Putting Ideas Together

  • Distribute our Putting Ideas Together Skill Builder. Have students complete it in small groups.
  • Discuss the assignment in the Think and Write box on page 13. Remind them to use descriptive details from both the article and timeline, including the captions on page 10.

Differentiate and Customize
For Second-Graders

Direct students to the second column on page 11. Ask them to follow along while you read aloud the first three sentences in the second paragraph. Help students identify the adjective and the noun it modifies in each sentence. (horrible tooth pain; oozy sores; rotting teeth)

For Small Groups

Have students read the article and timeline together. Ask them to write and illustrate two more entries for the timeline. These new entries should be based on information from the article.

For Struggling Readers

Read the lower-Lexile version of the articles aloud while students follow along. Ask them to underline details that describe how people took care of their teeth in ancient times, in the 1700s, and today.

For Advanced Readers

Have students read the article and timeline silently. Ask them to create an illustrated poster that shows how people solved a particular tooth problem in ancient times, in the 1700s or 1800s, and today.
