An orthodontic proxabrush (or proxy brush) is used to clean under the wire of your braces. It will help keep the hard to reach areas around your brackets clean for healthy teeth and gums.
It should be used in addition to regular brushing and flossing. It will not only help you keep each bracket clean, but it will help avoid those unsightly white marks left on teeth once braces are removed.
White marks on teeth after braces treatment are usually permanent and are the result of poor brushing and flossing.
