A brace or brace and bit is a hand tool used to drill holes, usually in wood. Pressure is applied to the top and the tool is rotated with a U-shaped grip. The U-shaped part is a kind of crankshaft. It gives the brace much greater torque than other kinds of hand drills. A brace can be used to drill much wider and deeper holes than can a gear-driven hand drill.
How Braces Work. Braces straighten teeth by putting steady pressure on your teeth and by staying in place for a certain amount of time. Most kids just need regular braces with wires and rubber bands doing their jobs to keep pressure on the teeth. The wires on your braces help to move your teeth, and the rubber bands help to correct the alignment (say: uh-LYNE-munt), which is the way your teeth line up. If your teeth need a little extra help, you may have to wear head- or neckgear with wires attached to your teeth.
