4. The teeth can be straightened.
Straight teeth give an esthetic appearance of the teeth, while a good bite provides a good function. Orthodontics is a treatment that straightens the teeth and corrects the bite at the same time. In addition, a pleasing facial profile, a pretty smile and beautiful tooth alignment should be sought after.
What types of tooth alignment problems disturb esthetics and function? Typical cases are shown below.
High Canine
| A high canine is a blocked-out eyetooth. This prevents the canines from playing the important role of controlling the function of the lower jaw. | 
|
Spaces between Teeth
| Neighboring teeth do not contact each other. The continuity of the dental arch is vital for the longevity of the teeth. | 
|
Open Bite
| The upper and lower front teeth normally overlap 3mm or so. There is a big open space between the upper and lower teeth in an open bite case. It is quite a challenge to keep the bite closed after correction. | 
|
Cross Bite
| The lower teeth are in front of the upper teeth. The lower lip is also protruding ahead of the upper lip and appears thicker in the frontal view. | 
|
Protruding upper Front Teeth
| Protruding upper front teeth are susceptible to trauma and pulp damage. A traumatized tooth may become fused to the surrounding bone, which may interfere with orthodontic treatment. |
