Orthodontic Conditions 

Orthodontic problems are caused by a variety of factors, including genetic traits and learned habits, such as thumb-sucking and tongue thrusting.  These conditions interfere with normal chewing, biting and speaking functions, and can negatively impact the appearance of teeth.

Here is a brief overview of some of the most common orthodontic conditions:

Overcrowding

Overcrowding occurs when there is limited or no space for adult teeth to erupt and align properly.  As a result of overcrowding, some teeth may twist, become impacted, or grow in a crooked manner.  The crowding of teeth is also known as a Type I malocclusion.  Though overcrowding is generally considered less serious than other types of orthodontic conditions, it looks less appealing and makes it difficult to thoroughly brush and floss teeth.

Overbite

An overbite occurs when the upper arch of teeth projects further than lower teeth.  In a more serious case, the lower teeth are completely overlapped by the upper teeth.  Signs of an overbite include a protruding upper lip, a gummy smile and the noticeable wearing of front teeth.

Underbite

An underbite is the reverse of an overbite, where the lower teeth are projected further than the upper teeth.  In many cases, the cause of an underbite is either a short upper jaw bone or an excessively large lower jaw bone.  Signs of an underbite include a protruding lower lip and a chin that appears overly large.

Crossbite

In many cases, an underbite also causes a crossbite.  Crossbite is the tilting of the lower teeth in relation to the upper teeth. This causes the upper teeth to hit the lower teeth on the tongue side, as opposed to the outside.
