Detecting Bite Problems

An orthodontist reviews many factors when first making an orthodontic evaluation. Although treatment plans vary from patient to patient, depending on the position and size of the jaws and teeth, the following facts are noted during an evaluation.

Please take a few minutes to review the diagrams below. This is part of what Dr. Henson will be looking for when he examines your bite.

Do the upper front teeth protrude or stick out?

This is excessive flaring of the upper front teeth and is one of the more common problems in orthodontics.

Is there a deep overbite?

The upper front teeth cover the lower, causing too much vertical overlap. Excessive vertical overlap (”overbite”) leads to excess wear of the teeth and shortening of the lower face.

Is there an underbite?

The upper front teeth fit inside the lower front teeth.

Is there an open bite?

You can stick your tongue between the front teeth when the back teeth are together.

Is there too little space for the teeth, or crowding?

Here the teeth appear quite crowded and may even overlap.

Are there large gaps or spaces between the teeth?

Here, you can see noticeably large spaces or gaps between the teeth.

Do the front teeth line up? Is the midline centrally located on your face?

The center line of the upper and lower front teeth should line up with each other and be located in the center of the face. When they do not, the probable cause is drifted teeth or a shifted lower jaw resulting in an improper bite.

Do the back teeth line up or do you have a cross bite?

If the upper back teeth fit inside, rather than outside, the lower back teeth, then you have a crossbite.
