Dental braces are appliances which are used to align or straighten the teeth and guide the teeth to the corrected position. They are made up of wires, brackets, and bands. Braces aid to correct irregular teeth positioning, jaw correction, improvement in chewing and smile aesthetics. Your dentist is the best person to guide on treatment options and modalities depending upon dentition.
The major reason for getting Braces on is to improve the facial appearance, what people do not know is that there are any other implications which require orthodontic treatment like open bite, jaw structure, crossbite etc.
