devices used by orthodontists to gradually reposition teeth to a more favorable alignment.
Today's braces are generally less noticeable than those of the past. Brackets, the part of the braces that hold the wires, are bonded to the front of the teeth. These brackets can be metal, clear, or tooth-colored. Wires that are used for braces today are also less noticeable. In some cases, brackets may be put on the back of the teeth (lingual appliances). Modern wires are also less noticeable than their predecessors. Today's wires are made of "space age" materials that exert a steady, gentle pressure on the teeth, making the tooth-moving process faster and more comfortable for patients.
