There are several types of braces: metal, clear, lingual (braces on the back of the teeth), some need colored rings to hold the wire, and others have small doors that hold the wire without colored rings. All types of braces can straighten teeth well, but some are less noticeable than others. North Texas PDO uses the Damon system, which allows them to straighten your teeth with or without colors.
