Common Problems

Malocclusion – Bad Bite

A malocclusion is a misalignment or incorrect relation between the teeth of your upper and lower jaw when they are closed. Basically it means having crooked teeth or a “poor bite”. Malocclusions are often associated with other dentofacial deformities. They are among the most common dental problems and their treatment benefits greatly of early diagnosis. Most cases of malocclusion are hereditary, so if a member of the family has bite problems or crooked teeth, then a check up with an orthodontist is strongly recommended at an early age.

Orthodontic treatment can correct the way teeth and jaws line up. Below are the most commonly encountered malocclusions, which are all treated by Dr. Randy L. Gittess.

braces for Crowding

Teeth 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.

Braces for Overjet

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.

Braces for Overbite

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.

Braces for Openbite

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.

Braces for Spacing

Teeth 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.

Braces for 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.

Braces for Underbite

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.
