Eating with a fixed tooth brace. Girl with a fixed tooth brace eating an apple. The orthodontic brace consists of small metal brackets that are glued to each tooth, plus a wire that is fitted to connect the brackets. The wire is tightened and it slowly, over weeks and months, corrects the alignment of the teeth. The procedure is usually carried out in children, but adult teeth can also be realigned.
