Great
Looking Teeth!
Thanks
to fluoride in toothpaste and drinking water, better nutrition
and improved dental care, Americans' teeth are healthier
than ever. But that doesn't mean you can neglect yours.
Decay
is still one cause of tooth loss, but gum disease is responsible
for most tooth loss in adults age 35 and older. The best way
to prevent these and other problems is to master the basics
of daily dental care, especially the proper ways of brushing
and flossing.
A great
looking smile is often the first thing that people will notice
about you and it is an easy thing to maintain if you take
proper care of your teeth.
Tooth
Growth & Development
What's
the difference between "baby" teeth and permanent teeth?
At
between six and ten months of age, most infants begin to get
their "baby" teeth. The central Incisors (front middle teeth)
usually come in first, and then teeth begin appearing on either
side and work their way back to the second molars. By the
time a child has reached three years old, most of the "baby"
teeth should be present. The process begins to repeat itself
when the child is about seven years old.
The central
Incisors fall out first and are replaced by permanent teeth.
By the age of 21, most people have all of their permanent
teeth. "Baby" teeth are important because they hold the place
for permanent teeth and help guide them into correct position.
"baby" teeth play an important role in the development of
speech and chewing. Are there different types of teeth? What
do they do? Your teeth look different from one another because
they are designed to do different things. The Incisors are
the teeth in the very front. They're the sharpest teeth, built
to cut food and shaped to shovel the food inward.
The Canine
teeth are in the corners of your mouth. Because they're meant
for grasping and tearing food, they have very long roots.
Premolars are located just behind your Canine teeth. Premolars
have a more flat chewing surface because they're meant for
crushing food.
The Molars
are the last teeth towards the back of your mouth. Molars
are much bigger than the Premolars and have bigger, flatter
chewing surfaces because their job is to chew and grind the
food into smaller pieces.
The
parts of a tooth?
A
tooth is basically made up of two parts: the crown and the
root. The crown is what you see when you smile or open your
mouth. It's the part that sits above your gumline. The root
is below the gumline. It makes up about 2/3rds of the tooth's
total length. Four different tissues make up each tooth. The
enamel is the durable, white covering. Enamel protects the
tooth from the wear and tear of chewing.
Dentin
supports the enamel on your teeth. It's a yellow bone-like
material that's softer than enamel and carries some of the
nerve fibers that tell you when something is going wrong inside
your tooth.
The Pulp
is the center of the tooth. It's a soft tissue that contains
blood and lymph vessels, and nerves. The pulp is how the tooth
receives nourishment and transmits signals to your brain.
Cementum
is what covers most of the root of the tooth. It helps to
attach the tooth to the bones in your jaw. A cushioning layer
called the Periodontal Ligament sits between the cementum
and the jawbone. It helps to connect the two.
Dental
Fact: Did you know that the enamel on your teeth is
the hardest substance in your body?

Wisdom Teeth
Wisdom
teeth or third molars usually appear around the age of 17
- 20. Wisdom teeth are an asset to the mouth when they are
healthy and properly positioned. Often, however, problems
develop that require their removal. When the jaw isn't large
enough to accommodate wisdom teeth, they can become impacted
(unable to come in or misaligned). Wisdom teeth may grow sideways,
get stuck under adjacent teeth, emerge only part way from
the gum or remain trapped beneath the gum and bone, develop
cysts and cause other kinds of problems. A large proportion
of the population does not have enough room for wisdom teeth
to assume a normal position.
Extraction of wisdom teeth is generally recommended
when:
Wisdom teeth only partially erupt. This leaves an opening
for bacteria to enter around the tooth and cause an infection.
Pain, swelling, jaw stiffness and general illness can result.
There is a chance that poorly aligned wisdom teeth will
damage adjacent teeth. A cyst (fluid-filled sac) forms, destroying
surrounding structures such as bone or tooth roots. Patients
should ask the dentist about the health and positioning of
their wisdom teeth.
The dentist may make a recommendation for removal or
send the patient to an oral surgeon for further evaluation.
What
is Plaque?
Plaque
is a film of bacteria and mucous that grows on your teeth.
Some of the bacteria in the plaque make acids which decay
your teeth. Other kinds of bacteria in the plaque make toxins
which cause gum disease. The easiest and most effective way
to remove the plaque from your teeth is to brush and floss.
Those costly rinses just don't do it! When the plaque is hardened
on your teeth it is called tartar or calculus. Then you need
a Dental Hygienist or Dentist to remove it by "scaling" the
tartar off.
Brushing
Brushing
removes food particles and plaque from your mouth, making
your teeth look cleaner and breath feel fresher. Brush at
least twice a day with a fluorinated toothpaste that has the
American Dental Association (ADA) seal of acceptance. Use
a toothbrush with soft, rounded bristles and replace it every
three months. Follow theses steps to clean all surfaces...
First...
To clean outer surfaces, tilt the brush so its bristles point
toward the gums. Use short, side-to-side strokes, moving across
your teeth in a circular motion. Also clean the gums.
Next...
To clean chewing surfaces of the molars, hold the brush flat.
Gently scrub your teeth by moving the brushed back and forth.
Then...
To clean inner surfaces of your back teeth brush in a circular
motion at a 45-degree angle. And don't forget the gums. To
clean the inner surfaces of your front teeth, hold the brush
vertically and use gentle up and down strokes.
Flossing
Brushing
keeps your teeth fairly clean, but it can't reach plaque and
food between teeth and under the gum line. Daily flossing
will keep plaque from building up in these hard to reach areas.
There are two types of floss -- waxed and unwaxed. Use whichever
you prefer. To make sure you floss all your teeth, start behind
the upper and lower molars at one side of your mouth and work
toward the other side and it up. Break off about 12 inches
of floss and wind most of it around your middle fingers.
Slide
the floss between the teeth using a gentle sawing motion until
it reaches the gum line. Carefully slide the floss between
the gum and tooth following the shape of the tooth. Scrape
the sides of the tooth by moving the floss up and down. Unwind
and use clean floss as you continue flossing.
How Do Braces Work?
Having
straight teeth is important. Teeth that are crooked or out
of place (misaligned) affect the way a person chews and talks
and how their smile looks. Because they have unnatural spaces,
crooked teeth are harder to clean and are more likely to have
cavities. In some cases, crooked teeth can affect the way
the jaws line up and can cause pain and discomfort. One method
to correct this is to have Orthodontic treatment (or braces
and retainers as they are sometimes called).
Orthodontic
treatment works by exerting a gentle pressure over time to
straighten teeth that are growing, or have already grown,
out of place.
Braces
have three basic parts:
1)
Brackets - brackets that are attached to each tooth
2)
Bonding or band - the material that attaches the bracket to
the tooth
3)
Arch Wire - a thin metal wire that runs from bracket to bracket
Braces have come a long way from the "train track" look of
years ago.
Today,
many orthodontic patients can get braces that attach to the
backs of the teeth, or use transparent brackets. A retainer
is a custom-made, removable appliance that helps keep teeth
in their new, straightened position after braces have been
removed. Retainers can also be used to treat more minor orthodontic
problems.
Endodontic
Treatments (Root Canal Therapies)
Our
teeth are meant to last a lifetime. Sometimes, however, damage
occurs to a tooth (often from a deep cavity or an injury that
causes a tooth to crack) and the inside of the tooth becomes
infected. This infection damages the pulp of the tooth. Left
untreated, the damaged pulp can cause infection that will
damage the bone around the tooth and cause swelling and pain.
If the damaged tooth is left untreated it becomes infected.
Your dentist or a dental specialist called an Endodontist,
may have to perform an endodontic treatment (often called
Root Canal Therapy) to save it. Endodontic treatment involves
opening the tooth, removing the damaged pulp, cleaning, shaping,
filling and sealing the tooth.

Tips For Dental Care
 |
Use
fluoride, which strengthens tooth enamel and helps
prevent the bacteria in plaque from causing cavities.
Some drinking water is fluoridated, and toothpastes
and mouth rinses with the ADA seal contain proper
amounts of fluoride. |
|
 |
Eat
a balanced diet that includes fruits and vegetables,
cereals, dairy products, and meat. Calcium is essential
for strong teeth and bones. Good sources include
milk, cheese, yogurt, and tofu. |
|
 |
Don't
chew on hard substances like ice or popcorn kernels
and don't grind your teeth. These habits can damage
to the enamel. |
|
 |
Cigarettes
and chewing tobacco can stain your teeth, and contribute
to gum disease or even cause oral cancer. |
|
 |
Excessive
amounts of coffee, tea or red wine may stain in
your teeth. |
|
 |
See
your dentist every six months for a general check
up and cleaning. |

Replace
That Old Tooth Brush!
--
Dentists and hygienists recommend changing your
toothbrush at least three times a year. Most Americans
replace their toothbrushes every 9 to 12 months.
But dentists recommend replacing a toothbrush every
three to four months, because worn bristles may
not clean teeth and gums effectively. So if your
current brush has seen better days, make a change.
And while you're at it look for a toothbrush that
has dual bristles to remove bacterial plaque between
teeth at the gum line. |
