With an overbite, the upper front teeth extend out over the lower front teeth, which can cause the lower front teeth to bite into the roof of the mouth.
In an underbite, the lower jaw extends out, causing the lower front teeth to sit in front of the upper front teeth.
An openbite is when the upper and lower front teeth do not overlap. This causes all the chewing pressure to be placed on the back teeth, which then makes chewing less efficient and may contribute to significant tooth- or teeth-wear. An overbite is typically the result of oral habits, such as tongue thrusting or thumb sucking.
In a crossbite, the upper teeth sit inside the lower teeth, which can lead to tooth stratification and misaligned jaw growth. In order to close the mouth, crossbite sufferers will usually have to move their lower jaw to the side or forward. This incorrect bite leads to an improper use of the lower jaws and sometimes brings about facial imbalance.
Upper Front Teeth Protrusion
With this type of bite, the upper teeth extend too far forward or the lower teeth are too far behind. This can have a significant impact on the appearance and function of teeth.
Dental Midlines Not Matched
When the dental midlines do not match, the back bite does not properly fit and match. This can have a negative effect on jaw function and proper dental function.
A missing incisor usually occurs when the teeth do not develop properly. It can also be the result of trauma.
Spacing usually results in gaps between the teeth. This generally happens when the teeth are smaller than normal and/or the jaws are bigger than normal. It can also occur when there are protrusive teeth, missing or impacted teeth, or abnormal tissue attachments to the gums.
In an overjet, the lower teeth are too far behind the upper front teeth. This can be caused by a skeletal asymmetry of the upper and lower jaw; flared upper incisors; missing lower teeth; or a combination of all three problems. In addition, oral habits such as thumb or finger sucking or tongue thrusting can worsen the condition.
Crowding occurs when teeth do not have sufficient room to erupt from the gum. It can often lead to periodontal problems and dental decay since it is more difficult to clean overlapping teeth’s surfaces.
