Preventative Dentistry
Preventative dentistry relies on good oral hygiene
and regular dental care, and is important throughout
your life, whatever your age. By practicing good
oral hygiene at home and visiting your dentist
regularly, you will help prevent dental problems
and save time and money. In the process, you
can
save your teeth and gums.

Fighting Plaque
By fighting plaque you can keep your teeth for
a lifetime. Today, in fact, older adults are keeping
their natural teeth longer because of scientific
developments and an emphasis on preventative dentistry.
Good oral hygiene requires an understanding of
plaque. Plaque is a sticky, colorless layer of
bacteria. When you eat carbohydrates (foods made
of sugar or starch) you feed this plaque, which
in turn produces acids that attack tooth enamel,
cause cavities, and develop a hard substance called
calculus (tartar). Uninterrupted, the acid attacks
can result in tooth decay and gum disease (also
known as periodontal disease). If left untreated,
gum disease can cause loss of teeth and bone.
At any age, you can begin the fight with plaque
and keep your teeth and gums healthy. It's really
quite easy. Simply:
- Brush your teeth twice a day
with a soft-bristled toothbrush and fluoride
toothpaste to remove food particles and plaque
from the tooth surfaces. While you're at it,
brush the top surface of your tongue to eliminate
bad breath and bacteria buildup.
- Clean between your teeth daily
with floss or an interdental cleaner. Decay-causing
bacteria can linger between teeth where toothbrush
bristles can't reach. Flossing removes plaque
and food particles from between the teeth and
under the gum line.
- Eat a balanced diet and limit
between-meal snacks. If a snack is needed, nutritious
foods such as raw vegetables, plain yogurt,
cheese or a piece of fruit should be chosen.
- Schedule regular check-ups.
Visit your dentist regularly (every 6 months)
for professional cleanings and oral exams.
- Ask your dentist about dental sealants,
a protective plastic coating that can be applied
to the chewing surfaces of the back teeth where
decay often starts.
- Wear mouth protection such
as a mouthguard when you play contact sports
or extreme sports.

Preventing Tooth Decay
Tooth decay (cavity or caries) can develop on
any surface of any tooth. Because cavities grow,
they are much easier and less expensive to treat
when they are small. A decaying tooth may not
hurt, so you may have a cavity and not realize
it. The dentist checks for tooth decay at your
regular check-ups and will periodically use x-rays
to check for decay between teeth. The dentist
treats tooth decay by cleaning out the cavity
and placing a restoration (filling) in the tooth.
By following the strategies listed above, you
can prevent tooth decay.

Preventing Gum Disease
Gum disease (also called periodontal disease)
is an infection of the tissues that support your
teeth. It is a major cause of tooth loss in adults.
Because gum disease is usually painless, you may
not know you have it. At each regular checkup
the dentist will measure the depth of the shallow
v-shaped crevice (called a sulcus) between your
tooth and gums to identify whether you have gum
disease.
Gum disease is caused by plaque, a sticky film
of bacteria that constantly forms on the teeth.
These bacteria create toxins that can damage the
gums.
Periodontal diseases attack just below the gum
line in the sulcus, where they cause the attachment
of the tooth and its supporting tissues to break
down. As the tissues are damaged, the sulcus develops
into a pocket; generally, the more severe the
disease, the greater the depth of the pocket.
Periodontal diseases are classified according
to the severity of the disease. The two major
stages are gingivitis and periodontitis.
In the early stage of gum disease, called gingivitis,
the gums become red, swollen and bleed easily.
At this stage, the disease is still reversible
and can usually be eliminated by daily brushing
and flossing.
In the more advanced stages of gum disease, called
periodontitis, the gums and bone that support
the teeth become seriously damaged. The teeth
can become loose, fall out, or have to be removed
by a dentist.
Some factors increase the risk of developing
periodontal disease:
- Tobacco smoking or chewing
- System-wide diseases such as diabetes
- Some types of medication such as steroids,
some types of anti-epilepsy drugs, cancer therapy
drugs, some calcium channel blockers, and oral
contraceptives
- Bridges that no longer fit properly
- Crooked teeth
- Fillings that have become defective
- Pregnancy
If you notice any of the following signs
of gum disease, see your dentist immediately:
- Gums that bleed easily
- Red, swollen, tender gums
- Gums that have pulled away from the teeth
- Persistent bad breath or bad taste
- Pus between your teeth and gums
- Permanent teeth that are loose or separating
- Any change in the way your teeth fit together
when you bite
- Any change in the fit of partial dentures

It is possible to have periodontal disease and have no warning signs.
That is one reason why regular dental checkups
and periodontal examinations are very important.
Treatment methods depend on the type of disease
and how far the condition has progressed.
Good oral hygiene at home is essential to keep
periodontal disease from becoming more serious
or recurring. You don't have to lose teeth to
periodontal disease. Brush, clean between your
teeth, eat a balanced diet, and schedule regular
dental visits for a lifetime of healthy smiles.
Normal, healthy gums: Healthy
gums and bone anchor teeth firmly in place.
Gingivitis: Gums are red, swollen
and bleed easily.
Periodontitis: Unremoved plaque
hardens into calculus (tartar). As plaque and
calculus continue to build up, the gums begin
to recede (pull away) from the teeth, and pockets
form between the teeth and gums.
Advanced periodontitis: The
gums recede farther, destroying more bone and
the periodontal ligament. Teeth — even healthy
teeth — may become loose and need to be
extracted.
The good news is that you can help prevent gum
disease by taking good care of your teeth every
day and having regular dental checkups.
You should replace your toothbrush every three
or four months — or sooner if the bristles
become frayed. A worn toothbrush will not do a
good job of cleaning your teeth. Children's toothbrushes
often need replacing more frequently than adults
because they can wear out sooner.
People who have difficulty handling dental floss
may prefer to use another kind of interdental
cleaner. These aids include special brushes, picks,
and sticks. If you use interdental cleaners, ask
your dentist about how to use them properly to
avoid injuring your gums.
