Lesson 3 Caring for Your TeethChapter 7




Tooth and Gum Problems

• Healthy Gums Check your gums regularly by

looking at them in the mirror. Your gums should be

bright pink and free from sores.

• What Is Plaque? Plaque is a mixture of bacteria,

saliva, and food particles. It is very sticky and binds

to the enamel of your teeth. The bacteria and acid

found in plaque can cause bad breath and even

worse—cavities!

Chapter 7




Dental Cavities

• What Is a Cavity? A cavity is a hole in your tooth

that is made by acids.

• How Are Cavities Formed? A cavity begins when

plaque forms on your tooth. The plaque holds the

acids very close to the enamel of the tooth. Even

though the enamel is very tough, the acids

eventually eat through it and make a hole.

Chapter 7



Lesson 3 Caring for Your TeethChapter 7

As dentin decays, the cavity eventually reaches the

pulp.

plaque.

Lesson 5 Caring for Your Ears

Objectives

Chapter 7




How You Hear

• Sound Vibrations Ears help you hear because tiny

parts inside your ears vibrate. Loud sounds make

the tiny parts vibrate much too hard. If you expose

your ears to loud sounds too often, the tiny parts of

your ear can break.

Chapter 7



Lesson 5 Caring for Your EarsChapter 7




Other Hearing Problems

• Earwax Buildup Sometimes, earwax builds up and

hardens in the canal. This can block the sound

waves and prevent the eardrum from vibrating.

• Middle Ear Infections Infections in the middle ear

can cause fluid buildup, which can also prevent the

eardrum from vibrating properly.

Chapter 7




Hearing and Ear Care

• Wear ear protection whenever you are around

loud sounds.

• Don’t insert anything into your ear canal.

• Gently clean your ears in the shower.
