An underbite is characterized by the lower jaw extending out, causing the lower front teeth to sit in front of the upper front teeth.
Spacing problems may be caused by missing teeth, or they may only be a cosmetic issue.
Upper Front Teeth Protrusion
The appearance and function of your teeth can be effected by this type of bite. It is characterized by the upper teeth extending too far forward or the lower teeth not extending far enough forward.
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.
The upper teeth sit inside the lower teeth, which may cause abnormal tooth wear and misaligned jaw growth.
The upper front teeth bite deeply over the lower front teeth, sometimes causing the lower front teeth to bite into the roof of the mouth.
Normal chewing is effected by this type of bite, in which the upper and lower front teeth do not touch making it difficult to bite off pieces of food. Openbite may cause a number of unwanted habits, such as tongue thrusting or, strangely, tongue thrusting might cause open bite. A thumb sucking habit may also contribuite to this problem. Severe openbites may not be correctable by braces.
