1. What is orthodontics?
Orthodontics is the branch of dentistry that specializes
in the diagnosis, prevention and treatment of dental
and facial irregularities. The technical term for these
problems is "malocclusion," which means "bad
bite." The practice of orthodontics requires professional
skill in the design, application and control of corrective
appliances, such as braces, to bring teeth, lips and
jaws into proper alignment and to achieve facial balance
|

2. At what age can people
have orthodontic treatment?
Children and adults can both benefit from orthodontics,
because healthy teeth can be moved at almost any age.
Because monitoring growth and development is crucial
to managing some orthodontic problems well, the American
Association of Orthodontists recommends that all children
have an orthodontic screening no later than age 7. Some
orthodontic problems may be easier to correct if treated
early. Waiting until all the permanent teeth have come
in, or until facial growth is nearly complete, may make
correction of some problems more difficult.
An orthodontic evaluation at any age is advisable
if a parent, family dentist or the patient’s
physician has noted a problem.

3. What causes orthodontic
problems (malocclusions)
Most malocclusions are inherited, but some are acquired.
Inherited problems include crowding of teeth, too much
space between teeth, extra or missing teeth, and a wide
variety of other irregularities of the jaws, teeth and
face.
Acquired malocclusions can be caused by trauma (accidents),
thumb, finger or dummy (pacifier) sucking, airway
obstruction by tonsils and adenoids, dental disease
or premature loss of primary (baby) or permanent teeth.
Whether inherited or acquired, many of these problems
affect not only alignment of the teeth but also facial
development and appearance as well.

4. What are the most
commonly treated orthodontic problems?
|
|
Crowding: Teeth
may be aligned poorly because the dental arch is small
and/or the teeth are large. The bone and gums over the
roots of extremely crowded teeth may become thin and recede
as a result of severe crowding. Impacted teeth (teeth
that should have come in, but have not), poor biting relationships
and undesirable appearance may all result from crowding. |
|
|
Overjet
or protruding upper teeth: Upper
front teeth that protrude beyond normal contact with the
lower front teeth are prone to injury, often indicate
a poor bite of the back teeth (molars), and may indicate
an unevenness in jaw growth. Commonly, protruded upper
teeth are associated with a lower jaw that is short in
proportion to the upper jaw. Thumb and finger sucking
habits can also cause a protrusion of the upper incisor
teeth.
|
|
Deep
overbite: A deep overbite or deep
bite occurs when the lower incisor (front) teeth bite
too close or into the gum tissue behind the upper teeth.
When the lower front teeth bite into the palate or gum
tissue behind the upper front teeth, significant bone
damage and discomfort can occur. A deep bite can also
contribute to excessive wear of the incisor teeth.
|
|
|
Open bite:
An open bite results when the upper and lower incisor
teeth do not touch when biting down. This open space between
the upper and lower front teeth causes all the chewing
pressure to be placed on the back teeth. This excessive
biting pressure and rubbing together of the back teeth
makes chewing less efficient and may contribute to significant
tooth wear.
|
|
|
Spacing:
If teeth are missing or small, or the dental arch is very
wide, space between the teeth can occur. The most common
complaint from those with excessive space is poor appearance.
|
|
|
Crossbite:
The most common type of a crossbite is when the upper
teeth bite inside the lower teeth (toward the tongue).
Crossbites of both back teeth and front teeth are commonly
corrected early due to biting and chewing difficulties.
|
|
|
Underbite or lower
jaw protrusion: About 3 to 5 percent
of the population has a lower jaw that is to some degree
longer than the upper jaw. This can cause the lower front
teeth to protrude ahead of the upper front teeth creating
a crossbite. Careful monitoring of jaw growth and tooth
development is indicated for these patients.
|

5. Why is orthodontic
treatment important?
Crooked and crowded teeth are hard to clean and maintain.
This may contribute to conditions that cause not only
tooth decay but also eventual gum disease and tooth
loss. Other orthodontic problems can contribute to
abnormal wear of tooth surfaces, inefficient chewing
function, excessive stress on gum tissue and the bone
that supports the teeth, or misalignment of the jaw
joints, which can result in chronic headaches or pain
in the face or neck.
When left untreated, many orthodontic problems become
worse. Treatment by a specialist to correct the original
problem is often less costly than the additional dental
care required to treat more serious problems that
can develop in later years.
The value of an attractive smile should not be underestimated.
A pleasing appearance is a vital asset to one’s
self-confidence. A person's self-esteem often improves
as treatment brings teeth, lips and face into proportion.
In this way, orthodontic treatment can benefit social
and career success, as well as improve one’s
general attitude toward life.

6. How long will orthodontic
treatment take?
In general, active treatment time with orthodontic appliances
(braces) ranges from one to three years. Interceptive,
or early treatment procedures, may take only a few months.
The actual time depends on the growth of the patient’s
mouth and face, the cooperation of the patient and the
severity of the problem. Mild problems usually require
less time, and some individuals respond faster to treatment
than others. Use of rubber bands and/or headgear, if
prescribed by the orthodontist, contributes to completing
treatment as scheduled.
While orthodontic treatment requires a time commitment,
patients are rewarded with healthy teeth, proper jaw
alignment and a beautiful smile that lasts a lifetime.
Teeth and jaws in proper alignment look better, work
better, contribute to general physical health and
can improve self-confidence.

7. How is treatment accomplished?
Custom-made appliances, or braces, are prescribed and
designed by the orthodontist according to the problem
being treated. They may be removable or fixed (cemented
and/or bonded to the teeth). They may be made of metal,
ceramic or plastic. By placing a constant, gentle force
in a carefully controlled direction, braces can slowly
move teeth through their supporting bone to a new desirable
position.

8. How important is patient
cooperation during orthodontic treatment?
Successful orthodontic treatment is a "two-way
street" that requires a consistent, cooperative
effort by both the orthodontist and patient. To successfully
complete the treatment plan, the patient must carefully
clean his or her teeth, wear rubber bands, headgear
or other appliances as prescibed by the orthodontist,
and keep appointments as scheduled. Damaged appliances
can lengthen the treatment time and may undesirably
affect the outcome of treatment. The teeth and jaws
can only move toward their desired positions if the
patient consistently wears the forces to the teeth,
such as rubber bands, as prescribed. Patients who do
their part consistently make themselves look good and
their orthodontist look smart.
To keep teeth and gums healthy, regular visits to
the family dentist must continue during orthodontic
treatment. Adults who have a history of or concerns
about periodontal (gum) disease might also see a periodontist
(specialist in treating diseases of the gums and bone)
on a regular basis throughout orthodontic treatment.
