Your gums anchor your teeth in your mouth and keep them in place.
Your teeth aid in forming certain speech sounds. Your teeth help shape and give structure to your mouth.

8. Tooth decay begins with the formation of plaque.
Tooth and Gum Problems
Tooth decay begins with the formation of plaque.
plaque A soft, colorless, sticky film containing bacteria that grows on your teeth
The germs in plaque cause bad breath. If left on the teeth, these germs combine with sugars to form an acid that causes tooth decay and gum disease.
If plaque is not removed, it eventually hardens and becomes tartar.

9. Tooth and Gum Problems
The germs in plaque cause bad breath. If left on the teeth, these germs combine with sugars to form an acid that causes tooth decay and gum disease.

10. Keeping Teeth and Gums Healthy
The three things you can do to prevent teeth and gum problems are brushing, flossing, and eating right.
When you brush, use a toothpaste that contains fluoride.
Brushing cleans the teeth, removes plaque, and stimulates the gums.
Flossing removes food particles and plaque from between the teeth and under the gum line that the toothbrush cannot reach. Flossing also helps to clean underneath braces.
Limit foods that are high in the mineral calcium and low in sugar.

Healthy Skin
Your skin is the biggest organ of your body.
The two main layers of the skin are the epidermis and the dermis.
The skin acts as a waterproof shield that defends the body against germs. It maintains body temperature and allows you to feel and sense pressure and temperature.
epidermis The thinner outer layer of the skin
dermis The thicker inner layer of the skin

13. The most important part of skin care is cleansing.
You should protect your skin with sunscreen.
sunscreen A cream or lotion that filters
out some UV rays
As your body develops, sweat glands become more active. Bacteria can grow in areas where you sweat, such as under your arms. Washing sweat away keeps your skin clean and smelling fresh.
The sun’s ultraviolet (UV) rays can cause sunburn and wrinkles and can increase your risk of skin cancer. Avoid direct sunlight between the hours of 10:00 A.M. and 4:00 P.M. Choose sunscreens with a sun protection factor (SPF) of 15 or higher.
The sun’s rays are strongest between the hours of 10:00 A.M. and 4:00 P.M.

15. Your hair is made up of a substance called keratin.
Healthy Hair
Your hair is made up of a substance called keratin.
The roots of the hair are in the dermis and are housed in pockets called follicles.
As new hair cells are formed, old ones are forced out.
The part of the hair that you can see is the shaft. The shape of your hair shafts determines whether your hair is wavy, curly, or straight. Like living skin, hair gets its color from the pigment melanin.

Hair Care
Tips for maintaining healthy hair include:
Wash regularly with a gentle shampoo and conditioner
Let hair dry naturally or use a hair dryer on low heat

Common conditions include:
Dry scalp
Oily scalp
Dandruff
Head lice
dandruff The flaking of the outer layer of dead skin cells
Dry scalp and oily scalp can be corrected by choosing the right shampoo.
