Metal braces are made of brackets that are bound to the tooth by either glue or a tight metal band. A thin wire runs through the brackets, applying pressure to the teeth. This pressure causes teeth to shift position, thereby straightening teeth and correcting bite and spacing issues.
Greg Jorgensen, DMD, Dentistry, answeredAll braces work by creating pressure against the teeth that causes the bone to remodel (or reform) around the tooth in the new position. These forces can be created by wires, bends in the wires, elastics (rubber bands), springs, or other attachments. Once the teeth are in their new position, the braces no longer produce pressure and can be removed.
