Where the bite is okay and the top teeth line up with the bottom teeth, but the teeth are crooked, crowded or turned.
Where the upper teeth appear to stick out past the lower teeth commonly referred to as an "over bite," "over jet," "deep bite" or "buck teeth."
Where the lower teeth appear to stick out past the upper teeth called an "under bite".
These are two common problems in children that have their origin in discrepancies between the size of the jaws (top and bottom), or discrepancies between the size of the teeth and the amount of space available.
- A posterior cross bite can appear at an early age, and depending on its cause (malpositioned teeth or misaligned jaws) treatment may be warranted early.
- Anterior open bites refer to a condition in which the top and bottom front teeth are not in contact (they do not touch each other when the patient bites). The origins of open bites can be traced to habits that patients have or had in the past, and occasionally to discrepancies between the sizes of the jaws.
