Braces, or orthodontic treatment, can benefit both children and adults. And recent advances in esthetics have made braces less noticeable than in the past. Brackets, the part of the braces that holds the wires, are bonded to the front of the teeth and can be metal, clear or toothcolored. Sometimes the brackets can be fastened to the back of the teeth. Newest in esthetic orthodontic treatment are “invisible” braces – clear, removable, molded plastic aligners that move your teeth into new positions.
