Oral Hygiene Basics:

What Are the
Different Parts of a Tooth?
- Crown: the top part of
the tooth, and the only part you can normally
see. The shape of the crown determines the
tooth's function. For example, front teeth are
sharp and chisel-shaped for cutting, while
molars have flat surfaces for grinding.
- Gumline: where the
tooth and the gums meet. Without proper
brushing and flossing, plaque and tartar can
build up at the gumline, leading to gingivitis
and gum disease.
- Root: the part of the
tooth that is embedded in bone. The root makes
up about two-thirds of the tooth and holds the
tooth in place.
- Enamel: the outermost
layer of the tooth. Enamel is the hardest,
most mineralized tissue in the body, yet it
can be damaged by decay if teeth are not cared
for properly.
- Dentin: the layer of
the tooth under the enamel. If decay is able
to progress its way through the enamel, it
next attacks the dentin, where millions of
tiny tubes lead directly to the dental pulp.
- Pulp: the soft tissue
found in the center of all teeth, where the
nerve tissue and blood vessels are. If tooth
decay reaches the pulp, you usually feel pain.
What Are the
Different Types of Teeth?
Every tooth has a specific job or function (Use
the dental arch in this section to locate and
identify each type of tooth):
- Incisors: the sharp,
chisel-shaped front teeth (four upper, four
lower) used for cutting food.
- Canines: sometimes
called cuspids, these teeth are shaped like
points (or cusps) and are used for tearing
food.
- Premolars: these teeth
have two pointed cusps on their biting surface
and are sometimes referred to as bicuspids.
The premolars are for crushing and tearing.
- Molars: used for
grinding, these teeth have several cusps on
the biting surface.

What
Is Good Oral Hygiene?
Good oral hygiene results in a mouth that
looks and smells healthy. This means:
- Your teeth are clean
and free of debris
- Gums are pink and do
not hurt or bleed when you brush or
floss
- Bad breath is not a
constant problem
If your gums do hurt or
bleed while brushing or flossing, or you
are experiencing persistent bad breath,
see your dentist. Any of these conditions
may indicate a problem.
Your dentist or hygienist can help you
learn good oral hygiene techniques and can
help point out areas of your mouth that
may require extra attention during
brushing and flossing.
How
Is Good Oral Hygiene Practiced?
Maintaining good oral hygiene is one of
the most important things you can do for
your teeth and gums. Healthy teeth not
only enable you to look and feel good,
they make it possible to eat and speak
properly. Good oral health is important to
your overall well-being.
Daily preventive care, including proper
brushing and flossing, will help stop
problems before they develop and is much
less painful, expensive, and worrisome
than treating conditions that have been
allowed to progress.
In between regular visits to the dentist,
there are simple steps that each of us can
take to greatly decrease the risk of
developing tooth decay, gum disease and
other dental problems. These include:
- Brushing thoroughly
twice a day and flossing daily
- Eating a balanced diet
and limiting snacks between
meals
- Using dental products
that contain fluoride, including
toothpaste
- Rinsing with a
fluoride mouthrinse if your dentist
tells you to
- Making sure that your
children under 12 drink fluoridated
water or take a fluoride supplement if
they live in a non-fluoridated area.
| Proper
Brushing Technique |
 |
 |
 |
|
Tilt
the brush at a 45°
angle against the
gumline and sweep or
roll the brush away from
the gumline.
|
Gently
brush the outside,
inside and chewing
surface of each tooth
using short
back-and-forth strokes.
|
Gently
brush your tongue to
remove bacteria and
freshen breath.
|
|
| Proper
Flossing Technique |
 |
 |
 |
|
Use
about 18" of floss,
leaving an inch or two
to work with.
|
Gently
follow the curves of
your teeth.
|
Be
sure to clean beneath
the gumline, but avoid
snapping the floss on
the gums.

What
is Proper Nutrition?
Proper nutrition means eating a balanced
diet so your body can get the nutrients
needed for good health. Every day, your
body renews itself, building new muscle,
bone, skin and blood. The foods you eat
provide the building blocks for these new
tissues. If your diet is low in the
nutrients your body needs, your mouth may
have a more difficult time resisting
infection.
If children do not eat a balanced diet,
their teeth may not develop properly. In
order for them to develop strong,
decay-resistant teeth, children need a
balanced diet with emphasis on calcium,
phosphorous, and proper levels of
fluoride.
What
are the Different Types of Nutrients?
A balanced diet consists of the following
nutrients:
- some carbohydrates
- the essential fatty
acids (found in fats)
- the essential amino
acids (found in proteins)
- fifteen vitamins
- approximately
twenty-five minerals
- water
Since our bodies are not
able to manufacture all the nutrients we
need, especially certain vitamins, we must
get them from food or supplements. The
U.S. Department of Agriculture advises
eating the following each day for the
general population:
- 6 to 11 servings of
bread and cereals
- 3 to 5 servings of
vegetables
- 2 to 4 servings of
fruit
- 2 to 3 servings of
dairy products
- 2 to 3 servings of
meat, poultry, fish, eggs, beans or
nuts
Why
is it Important to Eat Right?
A poor diet can lead to gum disease and
tooth decay.
Foods high in carbohydrates, sugars and
starches greatly contribute to the
production of plaque acids that
attack tooth enamel. Eventually, these
acids can cause tooth enamel to break
down, forming a cavity.
If you must eat foods high in sugar or
starch, try to eat them during meals
rather than between meals, and avoid any
foods that stick to your teeth as these
can produce more plaque. Most meals
already contain acid-producing ingredients
so, the less you expose your teeth to
these ingredients, the less plaque acids
attack your tooth enamel. Also, saliva
production rises during meals, helping
rinse food from the mouth.
