Metal Braces can be silver or golden. The are very strong and can withstand most types of treatment. At first, gums and cheek tissue may become irritated, but there are several first aid tricks to deal with the discomfort such as saltwater rinses and applying wax to the metal brackets.
Most traditional metal braces require an elastic O-shaped rubber band, called a ligature, to hold the arch wire onto the bracket. Sometimes metal tie wires (wires that twist around the bracket) are used in place of elastic ligatures.
Metal brackets tend to be less expensive than other types of brackets. And now, choices of colorful ligatures are available in a rainbow of colors to individualize personal style.
