Common Bite Problems

If your jaws don’t line up, your teeth don’t meet. The same is true if your teeth are turned, crowded, or missing. Bite problems fall into three main classes. You may have one or more of these common bite problems.

Jaws line up – Normal bite with crooked teeth (Class I): Jaws line up, but teeth may be crowded, turned, or spaced apart, some may be trapped in bone under the gum surface (impacted).

Jaws don’t line up – Overbite (Class II): Upper jaw is too large and sticks out (protrudes) over lower jaw. Or lower jaw is too small and too far back. Upper teeth protrude, often called “buckteeth.”

Jaw don’t line up – Underbite (Class III): Lower jaw is too large or too far forward. Or upper jaw is too small. Lower teeth close in front of upper teeth.

Other Common Orthodontic Problems

Other problems can occur even when the jaws line up well. The problems below may happen on their own or along with one of the classes described above.

Open Bite: Some of the back teeth close well, but other teeth don’t meet.

Closed (Deep) Bite: Upper teeth overlap lower teeth too much. Lower front teeth may hit the roof of the mouth while chewing.

Crossbite: Some of the upper teeth close behind lower teeth.
