What is malocclusion?
Malocclusion refers to any degree of irregular contact of the teeth of the upper jaw
with the teeth of the lower jaw. This would include overbites, underbites, openbites,
and crossbites. There is no specific system of deciding how much misalignment is too
much. Your child's orthodontist will decide whether your child's bite will need correction.
Malocclusion can cause problems with the child's bite, gum tissue, jaw joint, speech
development, and appearance.
Orthodontists are specially trained dentists. They specialize in the development,
prevention, and correction of irregularities of the teeth, bite, and jaws. Orthodontists
also have specialized training in facial abnormalities and disorders of the jaw. A
patient often talks with an orthodontist after receiving a referral from his or her
general dentist. In some cases, a specialist in jaw surgery may need to be consulted.
What causes malocclusion?
There is no one single cause of malocclusion. Many different factors are involved.
These include genetic factors and/or environmental factors. Children who suck their
thumbs or fingers beyond the age of 5 have an increased chance of developing malocclusion.
Children with a very small space between their primary teeth (baby teeth) are at risk
for having problems with malocclusion when their permanent teeth appear. This is because
the permanent teeth are larger and need more space.
How is malocclusion diagnosed?
Malocclusion is usually diagnosed based on a complete history and physical exam of
your child and your child's mouth. Your child's healthcare provider will probably
refer your child to a dentist or an orthodontist for complete evaluation and treatment.
The following tests may also be done to help evaluate the problem:
X-rays. A diagnostic test that uses invisible electromagnetic radiation to produce images
of internal tissues, bones, teeth, and organs onto film of the mouth or head, or to
capture the images in digital form on a computer.
Impressions of the teeth. Imprints of the teeth that are poured with plaster to make models of the mouth to
help evaluate the malocclusion.
Treatment for malocclusion
Specific treatment for malocclusion will be discussed with you by your child's dentist
or orthodontist based on:
Your child's age, overall health, and medical history
Extent of the condition
Your child's tolerance for specific medicines, procedures, or therapies
Expectations for the course of the condition
Your opinion or preference
Treatment is sometimes done in phases depending of the extent of the malocclusion.
In some cases, removal of the baby teeth is needed to help provide room for the permanent
teeth. Select permanent teeth are also sometimes removed. Other treatments may include:
The following foods should be avoided while wearing any type of mouth appliance:
Peanuts or other nuts
There may be some activity restrictions based on the type of appliance that is used.
Discuss this with your child's dentist or orthodontist.
