Orthodontic Dentistry Frequently Asked Questions
Q. What is orthodontic dentistry?
A. Orthodontic Dentistry or Orthodontics is described by the American Association of Orthodontics as the branch of dentistry that specializes in the diagnosis, prevention, and treatment of dental and facial irregularities.
Q. What is an orthodontist?
A. An orthodontist is a dentist who has undergone specialized orthodontic training to diagnose, prevent, and treat dental and facial irregularities in patients.
Within the U.S., orthodontists are required to complete a two- to three-year advanced residency program in orthodontics following the completion of their four-year graduate dental program. Each of these programs must be accredited by the American Dental Association's Commission on Dental Accreditation.
Q. What causes orthodontic problems?
A. Most problems are inherited, including tooth size and jaw size. These orthodontic problems may lead to crowding of teeth or spacing of teeth.
Overbites, underbites, extra or missing teeth, and irregularities of the jaws, teeth and face also are inherited.
Other orthodontic problems can be caused by accidents, pacifier or thumb sucking, dental disease, or the premature loss of either the primary or permanent teeth.
Q. What habits contribute to "bad bites"?
A. A number of childhood habits can lead to orthodontic problems, such as thumb or finger sucking, sucking on a pacifier, sucking on a lip, mouth breathing (often caused by enlarged tonsils and adenoids), fingernail biting, and "tongue thrust."
Q. When should a child's screening with an orthodontic dentist be scheduled?
A. The orthodontic dentist will advise the parent as to when to schedule an evaluation. It generally will be when the child is between the ages of seven and ten.
An early consultation is advised to identify any potential problems that require treatment. Delaying treatment can multiply some orthodontic problems.
Between the ages of 8 and 12, jaws are still growing; after that, the jawbones begin to harden and it may be more difficult to correct certain conditions.

How Malocclusion - or Bad Bite - Can Be Fixed by Braces for Teeth
It is ironic that one of the most common dental disorders is also the most neglected. The way the teeth fit together when the jaw closes and chews is of profound importance to the long-term health of your teeth.
If surfaces of the teeth interfere with how the jaw moves, the teeth can be worked loose or the enamel can be worn away. The muscles that move the jaw are very powerful and can do major damage to the teeth when the biting surfaces don't fit together properly.
The problem can be compounded if teeth interfere with functional muscle patterns, the jaw muscles will attempt to "erase" the part of the tooth that interferes by grinding against it all the more. This can lead to even more severe wear or it may crack off a cusp or split the tooth. Or it may loosen the tooth or cause it to move out of alignment. The excessive muscle activity often results in pain in the muscle itself. All of the jaw muscles can become sore including the temporal muscles that are the source of many so-called tension headaches.
Some excessive muscle activity may be caused by emotional stress. But with some special exceptions, damage done by stress induced grinding and clenching can be minimized to a manageable level by equalizing the biting surfaces that are in conflict with jaw movements. Proper fitting of braces for teeth can solve the problem by gently moving the teeth into a more optimal position.
The power of the jaw muscles may surprise you. Some people can exert over 900 pounds of compressive force with their jaw muscles so you can imagine how much damage such force can do when you close into a single tooth and then work it from side to side. The effect is very much like working a fence post loose as the bone around the root breaks down. If you can put your finger on any tooth in your mouth, and then squeezing your teeth together causes the tooth to move, you can be sure that it is just a matter of time before there will be a problem with that tooth.
Sometimes the muscle forces that work the tooth sideways stimulates bone around the root to build up and become stronger. When that happens, the tooth actually bends in its socket and this creates a microscopic chipping away close to the gum line to form a deep groove in the tooth. This is called an abfraction. These deep grooves at the gum line are often mistaken for toothbrush abrasion, but scientists have shown us that the grooves are actually the results of bending of the tooth in its socket. These grooves can lead to much sensitivity in those teeth because the opening into the tooth exposes nerves that can be exquisitely sensitive. Correction of the bite with Dental Braces to remove excessive lateral forces on the teeth in most instances either eliminates the sensitivity completely or reduces it to a much more acceptable level.
Patients should be aware that much confusion surrounds the importance of a harmonious bite, including many misconceptions that have been fostered by flawed research that has failed to properly relate the bite interferences to the position and condition of the temporomandibular joints. Knowledgeable clinicians, however, are very much aware of this relationship and can achieve excellent results with braces for teeth that will help make both your teeth and your jaw muscles more comfortable by bringing your whole biting into harmony.
