Dr. Bradley Nirenblatt will tell you that keeping your teeth clean is more important than ever when you have braces. Food bits have more spots than usual to hide in your mouth, so you must be diligent in order to avoid bad breath, swollen gums, discolored teeth and cavities. If you remove plaque regularly during treatment, you'll experience better results and could possibly reduce your treatment time.
Here is a very concise video explaining the proper way to floss your teeth with braces. Give Nirenblatt Orthodontics a call if you have more questions about flossing. Enjoy!
