A malocclusion is a deviation in intramaxillary and /or intermaxillary relations of teeth from normal occlusion. Also referred to as a bad bite, malocclusions are often associated with other dentofacial deformities. The American Association of Orthodontists recommends all children get a check-up with an orthodontist by age 7.

Crossbite of Front or Back Teeth

The upper teeth sit inside the lower teeth, which
may cause tooth stratification and misaligned
jaw growth.

Overbite

The upper front teeth extend out over the lower
front teeth, sometimes causing the lower front
teeth to bite into the roof of the mouth.

Underbite

The lower front teeth extend over the upper
front teeth, less common than the overbite
and mainly effecting those of Asian decent.

Openbite

Proper chewing is impacted by this type of bite, in
which the upper and lower teeth do not overlap.
Open bite may be caused by things like thumb
sucking or tongue thrusting.

Crowding

Crowding occurs when teeth have insufficient
room to erupt from the gum. Crowding can often
be corrected by expansion, and many times
tooth removal can be avoided.

Excess Spacing

The opposite of crowding is spacing, an excess
of space for teeth which results in gaps between
the teeth. This problem often occurs when the
teeth are smaller than the available space.
Dental Midlines Not Matched

Protruded Teeth

When the upper front teeth stick out too far
forward, or the lower teeth don’t extend
enough this is called protrusion. Because of
the abnormal contact between the upper and
lower front teeth it could cause injury to the
lower teeth. It also causes poor bites and
may even be from uneven jaw growth.
This problem can be caused by thumb
and finger sucking.

This type of problem is caused when the back bite does not fit and match appropriately, which may negatively impact jaw and proper dental function.

Also, if you notice any of further common problems in your child, check with your orthodontist:

Final treatment decisions should be made between the parent, child’s dentist and orthodontist.
