Metal braces are fixed braces that consist of metal brackets which are attached to the front surface of your teeth and are connected with a metal wire. Fixed braces need to be put on and removed by a dentist or an orthodontist, which is why they are ‘fixed'. Patients can wear them on both the top and bottom arches or just on one arch, depending on the requirement of the case. The metal brackets are connected by a wire thta gradually applies pressure ton the teeth and guides them into the desired position over time.
