Orthodontics deals with correcting irregularities on teeth and jaw bones by means of brackets as well as other modern methods.

Orthodontic therapy, though ideally applied during mixed dentition period, can be realized at any age in contrary to common belief. Malocclusion and convoluted teeth lead aesthetic, functional and phonation impediments. As teeth don't contact each other on ideal contact points, decays are formed easily. All these malformations can be eliminated with orthodontic therapy.

On the other hand, severe skeletal defects cannot be solely corrected with orthodontic therapy . Instead both orthodontic and orthognathic surgical treatment should be applied together. Detailed information is given about orthognathic surgery under Mouth Tooth Jaw Diseases and Surgery.
