Crowding is a common orthodontic problem.
Crowded teeth can be unattractive and difficult to clean.
Protrusion
Protruded teeth can be unattractive
and are more prone to damage.
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 crossbite 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.
