Crowded teeth or overlapped teeth.
The upper front teeth completely overlap the lower teeth. Also known as overbite.
Noticeably large gaps between teeth.
The upper back teeth bite on the inside of the lower teeth.
Front Teeth Lining Up (Midlines)
The spaces between the two lower front teeth should line up with each other, as well as with the bridge of the nose. When they do not, the probable cause is drifted teeth or a shifted lower jaw, resulting in an improper bite.
The patient can stick his or her tongue between the upper and lower front teeth when the back teeth are together.
Protruding Upper Teeth
This is the most common orthodontic problem and is sometimes called “buck teeth.” Protruding upper teeth can sometimes be called overjet.
The upper front teeth fit inside the arch of the lower teeth.
