Metal braces are typically smaller and more comfortable. These are the traditional braces used in orthodontics that involve metal brackets and wires. Metal braces have stood the test of time and are extremely effective at treating overcrowding as opposed to other options. Orthodontists have the control needed to move teeth using small adjustments. While they are more visible than other braces, today’s metal braces are much smaller and are popular among patients who like to choose multi-coloured elastics to go around the braces.
