Common Problems


In an underbite, the lower teeth and/or jaw are positioned too far forward relative to the upper teeth.  It can cause facial disharmony, jaw discomfort, and excessive wear of the teeth.


Spacing problems may be caused by missing or impacted teeth, or they may be caused when the size of the teeth is not in harmony with the jaw size. Spaces allow food to impact between the teeth, which can lead to gum and bone problems later in life.

Upper Front Teeth Protrusion (Overjet)

This is a common orthodontic problem where the top front teeth are positioned too far forward relative to the lower teeth and jaw.  The cause can be hereditary in nature or it can be created by other factors such as thumb-sucking or lip-biting.  Front teeth in this type of bite are twice as likely to be fractured in injuries to the face or mouth.


Crowding occurs when the size of the teeth exceeds the space available in the jaw. The teeth turn and overlap and they grow in. Crowding can make it very difficult to properly care for the teeth and when teeth are pushed out of position they can develop gum and bone defects. While children are still growing, an orthodontist can often re-arrange the teeth and work with growth to bring the teeth into the correct position. In moderate to severe cases of crowding, however, teeth may need to be removed.


In a crossbite, one or more upper teeth sit inside the lower teeth. This can cause tooth damage and/ or misaligned jaw growth and stress on the jaw joint (TMD). If the crossbite is caused because the upper jaw is too constricted, it can be corrected with an expander.

Deepbite (Overbite)

The upper front teeth have grown over and cover up the lower front teeth, sometimes causing the lower front teeth to bite into the roof of the mouth.  It can also cause excessive wear of the incisor teeth.


Proper chewing is impacted by this type of bite, in which the upper and lower front teeth do not overlap. Openbite may cause a number of unwanted habits, such as tongue thrusting.

Dental Midlines not Aligned

This type of problem is caused when the back bite does not match appropriately or when the front teeth are out of alignment.  It may negatively impact jaw and dental function.
