Picture of Types of Braces
Metal braces are still used, but many other options are available. Brackets — the parts that attach to each tooth -- can be clear, tooth-colored, or multi-colored. They can even be attached to the back of the tooth so they are out of view. There are even "invisible" braces that use a series of clear, plastic molds to gradually move the teeth into alignment.
