Orthodontics is a branch of dentistry which involves:
A thorough and proper assessment and evaluation of the current alignment of your teeth & jaws.
Diagnosing the relationship between the sizes of the jaws, the sizes of the teeth, and, how they fit together in both upper and lower jaws. This involves x-rays (front, profile and possibly hand in kids), photos and models of your teeth.
Exploring the various options of treatment to improve/rectify the above. (Normally presented and discussed with you in a dedicated consultation appointment). This includes estimate of costs & length of treatment.
The treatment involves the movement of teeth into the best possible position to allow straighter, more aesthetically pleasing smile and a more balanced and stable bite going forwards.
