Absolutely it is. There are two factors: health and aesthetics.
If teeth remain twisted or crowded, it is far more difficult to maintain dental hygiene. This may lead, in the future, to caries, periodontal disease and even the loss of the teeth.
There are certain features related to orthodontics that if left untreated may lead to: wearing out or fracturing of the tooth surface, poor chewing, tension in the gums and bone, or bad bite, which may lead to headaches or a stiff neck.
Aside from health issues, there is a clear aesthetic benefit to having an attractive smile. Orthodontic treatment not only improves the appearance of the teeth but also that of the lips and face. We should not underestimate the effect of a good smile on our self-confidence or on the development of satisfactory personal and professional relationships.
