Crowding is a common orthodontic problem. Crowded
teeth can be unattractive and difficult to clean.
Protruded teeth
Protruded teeth can be unattractive and more prone
to damage. The lower front teeth often over-erupt
and damage the palate behind the top front teeth.
Under bite
The lower front teeth protrude beyond the upper
teeth.
An under bite can be unattractive and can cause
uneven wear of the front teeth.
Deep
bite
The upper front teeth cover the lower teeth.
A deep bite can cause excessive wear of the front
teeth and gum damage behind the upper front teeth
Open bite
An open bite exists when some teeth don't meet.
It can cause eating problems, speech problems, and
excessive wear of those teeth which do meet. An open
bite can also be unattractive.
Cross
bite
The upper teeth should fit outside the lower teeth
like a lid on a box. If the upper jaw is too narrow,
the lower jaw usually swings to one side to allow
the teeth to mesh. A cross-bite results.
Missing teeth
Missing teeth can be very unattractive.
By moving all teeth into correct position, proper
space can be created to facilitate replacement of
the missing teeth.
Thumb
sucking
Sucking the thumb (or fingers) can deform nearby
teeth and supporting bone.
