Orthodontics is a branch of the dentistry. They adjust the upper and lower jaws that are positioned improperly and correct the irregularities in the teeth. These corrections are necessary to prevent tooth decay and also to restore an aesthetic appearance. For best results, the treatment is recommended after the age of 7 and before adulthood. Although the treatment lasts 1-2 years, it may vary from person to person. The treatment of adults last longer than teenagers. To straighten them and move them into a better position, the treatment is applied by experienced orthodontists with the help of brackets attached to the teeth. Brackets are transparent or tooth colored. They can be removable or fixed.
